mussh

MUltihost SSH Wrapper

Mussh is a shell script that allows you to execute a command or script over ssh on multiple hosts with one command. When possible mussh will use ssh-agent and RSA/DSA keys to minimize the need to enter your password more than once. Unlike clusterssh or mssh, mussh is just a shell script wrapper for ssh with concurrency support. It is intended to make running identical commands or scripts on almost any number of hosts possible with minimal overhead. There is no GUI and the only language used is bash.
