You sysadmin types who need to run
the same commands on multiple
systems may be interested in this
code!
From the page:
"Cluster SSH opens xterm windows with connections
to specified hosts and an administration console. Any
text typed into the administration console is replicated
to all other connected and active windows. This tool is
intended for, but not limited to, cluster administration
where the same configuration or commands must be
run on each node within the cluster. Performing these
commands all at once via this tool ensures all nodes
are kept in sync. This tool works on Solaris and Linux,
and should work on other POSIX systems (e.g.
OpenBSD)."
