Tentakel to execute commands on multiple Linux or UNIX Servers

Many times, you want to execute a command not only on one server, but also on several servers. For example, find out * Version of kernel * Version of Apache web server * Update static html or images files on all web servers via rsync * Find out user information, server information, memory usage etc * Security/patch checking tentakel 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.

ssh on multiple servers Using cluster ssh -- Debian Admin

Ever had to make the same change on more than one Linux/unix server? Find it annoyingly painful to keep repeating the exact same commands again and again and again? This tool addresses exactly this problem. You run a utility (cssh) providing a number of server names as parameters, and then xterms opens up to each server with an extra “console” window. Anything typed into the console is replicated into each server window (so, for examples, you can edit the same file on N machines at the same time, or run the same commands with the same parameters across those servers). It is also possible to type into the server windows directly, or temporarily disable replication to one or more of the servers through the “Hosts” menu.

SSH Filesystem

by 2 others
This is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side there's nothing to do. On the client side mounting the filesystem is as easy as logging into the server with ssh. The idea of sshfs was taken from the SSHFS filesystem distributed with LUFS, which I found very useful. There were some limitations of that codebase, so I rewrote it. Features of this implementation are: * Based on FUSE (the best userspace filesystem framework for linux ;-) * Multithreading: more than one request can be on it's way to the server * Allowing large reads (max 64k) * Caching directory contents
