For general cluster administration tasks, let me recommend tools such
as:

dsh: like "ssh HOST COMMAND" but does multiple hosts at once
http://www.netfort.gr.jp/~dancer/software/dsh.html

Fabric: remote deployment and remote command running utility
(more oriented toward scripting a solution than ad hoc)
http://fabfile.org/

Puppet, Chef, Kokki: more full-blown cluster management solutions;
based on the idea of writing recipes and running them automatically
