I have a cluster setup at the momment doing distrubuted compiling tasks over 3 computers: my master (localhost) and 2 of my slave nodes on a private subnet. I was going to use OpenPBS and issue tasks in the form of a script: ie shutdown all slaves at once etc, a portable batch system, but my question is this: Without using OpenPBS and the like, how could I get a script or something simuler to open up an ssh session with one of my nodes and issue a command. My slaves are setup using host based authentication with a blank ssh dsa key (so once you gain root on the master it is an instant connection to my slaves).
How would this be possible without physicaly initiating an ssh connection to my slaves and using the keyboard to execute a linux command. You get the idea
Thanks a ton.
its just as simple as ssh node01 <command> wow I totaly overlooked that
