Howto Use SSH To Run Command On A Remote Machine

This article examined a simple, but powerful, method to run commands on a remote machine using combination of ssh and a shell script:

Use Secure Shell (SSH) to run commands on remote UNIX systems and, with some simple scripts, put together a system that enables you to manage many systems simultaneously from one machine without having to log in directly to the machines themselves. Also examine the basics of a distributed management system and some scripts and solutions using the technique.

I have already covered how to execute commands on multiple Linux or UNIX servers via a shell script. The disadvantage of shell 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 (highly recommended) , you run distributed command execution. Also, you can execute commands on multiple Linux or UNIX servers using special tools such as multixterm from expect project.
