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". ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - CDN Systems, Internap, Inc. http://www.internap.com - - - - When in doubt, mumble. - ----------------------------------------------------------------------
