Let me also add that if you permit ssh access to the machines
(preferably by key only), a spectacularly useful tool is "clusterssh"
(aka "cssh").  It fires up ssh sessions to a list of machines, each in
its own window, plus a "master" window where whatever you type gets sent
to ALL the other windows.  "yum install clusterssh".
