Unix+clones Execute Commands on Multiple Linux or UNIX Servers part II
Post date: December 28, 2005, 04:12 Category: System Views: 1020 Comments: 0
Tutorial quote: I have already covered how to execute commands on multiple Linux or UNIX servers via shell script. The disadvantage of script is commands do not run in parallel on all servers. However, several tools exist to automate this procedure in parallel. With the help of tool called tentakel, you run distributed command execution. It is a program for executing the same command on many hosts in parallel using ssh (it supports other methods too). Main advantage is you can create several sets of servers according requirements. For example webserver group, mail server group, home servers group etc. The command is executed in parallel on all servers in this group (time saving). By default, every result is printed to stdout (screen). The output format can be defined for each group.
Unix+clones Sudo FAQ

Tutorial quote: Sudo is a simple program which allows the administrator to give regular users extra permissions to execute the commands they would normally not be allowed to use. Thanks to sudo, we can execute commands that are usually restricted to the root account. In practice, it looks like that: instead of typing su ->password -> command you type sudo command. In order to use sudo you need to configure it properly. This FAQ is supposed to help you with this task.

Tutorial quote: Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecure channels. It is intended as a replacement for telnet, rlogin, rsh, and rcp. For SSH2, there is a replacement for FTP: sftp.This might be useful if you are trying to connect everytime to your server remotely.

Unix+clones How To Look Like A UNIX Guru
Post date: October 29, 2006, 20:10 Category: Miscellaneous Views: 2936 Comments: 0
Tutorial quote: UNIX is an extremely popular platform for deploying server software partly because of its security and stability, but also because it has a rich set of command line and scripting tools. Programmers use these tools for manipulating the file system, processing log files, and generally automating as much as possible.

If you want to be a serious server developer, you will need to have a certain facility with a number of UNIX tools; about 15. You will start to see similarities among them, particularly regular expressions, and soon you will feel very comfortable. Combining the simple commands, you can build very powerful tools very quickly--much faster than you could build the equivalent functionality in C or Java, for example.

This lecture takes you through the basic commands and then shows you how to combine them in simple patterns or idioms to provide sophisticated functionality like histogramming. This lecture assumes you know what a shell is and that you have some basic familiarity with UNIX.

Debian Mini-Howto for User Mode Linux
Post date: April 12, 2005, 12:04 Category: System Views: 725 Comments: 0
Tutorial quote: UML ("User Mode Linux") allows you to run multiple Linux servers on one physical machine. This can be handy for many different purposes. For example, you might want to give different people root rights, but prevent them from interfering with one another. Or, you might want to have several identically configured servers, one for production, one for development, and one for testing, but without investing in multiple physical machines.

Once you have prepared your machine for running UML instances as described in the following section, adding new instances will take less than five minutes. The preparation, however, might take a bit longer.
