The easiest way would probably be to set up public key authentication using SSH:
i use RedHat 7.2, i have many pcs in my LAN (linux m/c). i wrote a program and i want to ask is there any command that can help me to run this program on all these machines at ones from my server? is it possible?
Is there any other way to be done programmatically? i want to write a shell script (tcsh or bash) r to use Perl that execute my program on each m/c (i have a list of the names...)
