功能丰富的 Perl: 管理 Linux 配置文件
一般的开发者用于定位、学习和调试配置文件的所花费的时间,比您预期的要更长。不过,使用一个您可能每天都在用的工具:CVS 树,您就可以节约那些时间——并减轻精力和挫折的负担。使用这些技巧来备份、发布最令您头痛的 Linux ™(和 UNIX ®)配置文件,并使其变得可移植。

Linux threading models compared: LinuxThreads and NPTL点击:22
 分类:Linux 时间:2006-8-6 21:11:37 xds2000收录 复制到我的网摘
developer must knows key differences about LinuxThreads and NPTL.
Let's review the high points of LinuxThreads' design specifics:

One of the notable features of LinuxThreads is the manager thread. The manager thread fulfilled these requirements:

The system must be able to react to fatal signals and kill the entire process.
The de-allocation of memory used as stacks must happen after a thread is finished. Therefore, the thread cannot do this itself.
Terminating threads must be waited on so that they don't turn into zombies.
The de-allocation of thread-local data requires iterating over all threads; this must be done by the manager thread.
If the main thread needs to call pthread_exit(), the process is not terminated. The main thread goes to sleep, and it is the job of the manager thread to wake up the main thread when all other threads have been killed.

Linux iSCSI target implementation
Linux iSCSI target implementation
The Linux iSCSI target driver allows to export an arbitrary number of block devices via the iSCSI protocol to other clients on a TCP/IP network. The clients will then see these devices as normal SCSI devices.

For more information about the iSCSI protocol see the latest protocol draft at http://www.ietf.org/internet-drafts/draft-ietf-ips-iscsi-20.txt.

This driver requires a recent Linux 2.4 kernel. The README file in the archive contains more detailed instruction on how to configure and build the driver. The latest driver release is linux-iscsi-target-20040211.tar.gz (Older releases are moved into this directory).

iSCSI initiator drivers for Linux are available from

Solve application problems with tracing
Peer into the behavior of an application with truss. When an application doesn't work as expected, you typically look at application and system logs as a first recourse. But when logs don't help, UNIX?provides a powerful set of tools that you can use to trace the application while it runs. Armed with these traces and a bit of knowledge about UNIX, you can easily solve your application problems.

Setting Up A Highly Available NFS Server | HowtoForge - Linux Howtos and Tutorials点击:17
 分类:Linux; NFS_Server 时间:2006-3-28 0:28:51 xds2000收录 复制到我的网摘
Setting Up A Highly Available NFS Server
NFS server可以看作是一个FILE SERVER,它可以让你的PC通过网络将远端得NFS SERVER共享出来的档案MOUNT到自己的系统中,在CLIENT看来使用NFS的远端文件就象是在使用本地文件一样。 NFS协议从诞生到现在为止,已经有多个版本,如NFS V2(rfc1094),NFS V3(rfc1813)(最新的版本是V4(rfc3010)。
In this tutorial I will describe how to set up a highly available NFS server that can be used as storage solution for other high-availability services like, for example, a cluster of web servers that are being loadbalanced. If you have a web server cluster with two or more nodes that serve the same web site(s), than these nodes must access the same pool of data so that every node serves the same data, no matter if the loadbalancer directs the user to node 1 or node n. This can be achieved with an NFS share on an NFS server that all web server nodes (the NFS clients) can access.

中国Linux公社 - 编译你自己的Linux内核(Kernel)点击:23

编译你自己的Linux内核(Kernel)
本文的结构如下。首先讨论你在Internet的什么地方能够找到内核的源码以及如何安装这些源码, 然后通过屏幕截图讨论使用图形界面配置内核。 一旦内核配置完毕,它就需要被编译,但是一个新编译的内核并不能直接使用。 首先,新内核需要和引导程序“lilo”一起安装,然后,在使用lilo前你必须写配置文件“/etc/lilo.conf”。 另外,还有需要指出一些特殊的要点(specific points),比如笔记本电脑需要的PCMCIA支持。 看上去象信用卡的PCMCIA,小型板卡(small inserts)通常负责联网任务,在2.4.x的内核中已经可以直接提供支持。 但之前的内核需要重新编译安装后才能提供PCMCIA支持。SuSE Linux还有一个问题,那就是ALSA声卡驱动程序的音效支持。 这些驱动程序并不是内核的一部分,它们需要被编译进去然后重新安装,因为原始的驱动程序通常没有工作。 更麻烦的是,从一个系列的内核转到另一个系列的内核,比如从2.2.x系列转到2.4.x系列, 可能会由于使用某种(某些)内核工具(kernel utilities)而产生一些问题。 这就是所谓的“modutils”(译者注:可以看为“Modules Utilities”的所写,这样就不会对这个名称感到费解了),包括代码(code)需要载入(load)的内核模块(kernel module):图3解释了什么是内核模块。 有时新内核不知道如何处理老的modutils,所以你必须编译和安装更新版本的modutils。 这样的问题虽然不多但是它们的确存在,而且目前只能预先指出它们。

Encrypt filesystems with EncFS and Loop-AES
Encrypted filesystems may be overkill for family photos or your résumé, but they make sense for network-accessible servers that hold sensitive business documents, databases that contain credit-card information, offline backups, and laptops. EncFS and Loop-AES, which are both released under the GNU General Public License (GPL), are two approaches to encrypting Linux filesystems. I'll compare the two and then look at other alternatives.

CLI Magic: Tracking system performance with sar
Sar is the "system activity report" program found on *nix systems. In Linux, you can usually find it in the sysstat package, which includes programs and scripts to capture and summarize performance data, then produce detailed reports. This suite of programs can be useful in tracking down performance bottlenecks and providing insight into how the system is used throughout the day.

linux下的tcp调优

Red Hat 7.3 的缺省值如下:
tcp_fin_timeout 180
tcp_keepalive_time 7200
tcp_window_scaling 1
tcp_sack 1
tcp_timestamps 1
在下面的设置中,更改某些值能增加服务器可处理的 TCP/IP 连接的数量,缩短服务器在终止失效连接前的等待
时间,禁用一些不必要的 IP 扩展。把这些设置添加到 /etc/sysctl.conf 文件,然后重新启动网络守护程序(
/etc/rc.d/init.d/network restart )。

# Decrease the time default value for tcp_fin_timeout connection
net.ipv4.tcp_fin_timeout = 30
# Decrease the time default value for tcp_keepalive_time connection
net.ipv4.tcp_keepalive_time = 1800
# Turn off tcp_window_scaling
net.ipv4.tcp_window_scaling = 0
# Turn off the tcp_sack
net.ipv4.tcp_sack = 0
#Turn off tcp_timestamps
net.ipv4.tcp_timestamps = 0

恢复 EXT3 Superblock 的正确方法
前几天遇到一个 Linux Ext3 文件系统超级块(Superblock)错误问题.


.... bad superblock on /dev/hda4一个同事做的恢复, 结果把数据都抹掉了. 后来想想, 当时的直接 fsck 的恢复方法不对. 正确的方法应该是这样的:

1 获取错误的出错磁盘(或者设备)块的大小.
有很多种方法可以得到. 比如,


# tune2fs -l /dev/hda4其实大多数情况下是 1 K.

Sniffing packets over your LAN is an invaluable tool for debugging network problems or collecting measurements. Sometimes the commonly available tools, such as tcpdump or ethereal, will not exactly fit your needs and writing your own sniffer can be of great help. Thanks to the LPF, you can do this in a simple and efficient way.
