Welcome to LQ.

The easiest way would probably be to set up public key authentication using SSH:

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...)
thanks

Sure, once you have set up the authentication you just need to loop through each host in a list and run the command - ie:
hosts="hosta hostb hostc"
for host in $hosts;do
ssh user@$host command
done

mmm this is nice, but someone told me that there is a command i think P2 or something like that : P2 command host-list . is it a valid command?
thanks
