Last night at PLUG N we were talking about running the same command on a bunch of servers. Here is some follow-up for that. I was thinking of "multixterm", which seems to be part of the expect-dev (possibly just expect on some distros), but the references on the NIST site seem otherwise dead.  Then there is "Execute commands simultaneously on multiple serversUsing PSSH/Cluster SSH/Multixterm"  and "Parallel SSH execution anda single shell to control them all" . There's this non-Interactive one: http://www.stearns.org/fanout/ Run non-interactive commands on remote machines simultaneously And of course, CFEngine , Puppet  and chef  and a comparison of a bunch of config management tools , but these are all more heavy duty than the original topic. I haven't really used any of them, but from my brief survey, PSSHsounds the most interesting since it includes (scriptable) pssh, pscp,prsync, and pnuke. http://code.google.com/p/parallel-ssh/ If anyone (Kevin?) dives into these, let us know how it works out.
I have not used pssh yet, it's in the todo list, but I have experimented a bit with classic SSH and SUDO to automate user creation on multiple servers.
It took me some time to deal with sudo asking for a password, but I reached a somewhat acceptable solution. By the way, if someone knows of an ssh-agent-like sudo agent, that could transport my sudo session from a machine to another, I'd love to hear about it.
Here is the blog post I wrote: http://jve.linuxwall.info/blog/index.php?post/2011/07/22/Using-ssh-agent-with-a-relay-to-create-a-user-account-on-multiple-servers
