remote_update.pl is a script that uses Expect, PERL, and SSH to perform automated remote administration on a large number of hosts. The script is given a set of passwords, a list of remote hosts, a collection of files to copy over, and a set of scripts to run on the remote hosts. The only thing required to be running on the remote machines is SSH. It tries to copy all of the needed files and scripts to the remote machine via SCP as a non-root user, SSH in as the non-root user, su to root on the remote machine if applicable, and then execute the scripts you provided. This process is cycled for every host given. su'ing to root can be turned off, and also the tasks can be parallelized in multiple processes.
