With extreme care.

If you must do this, look at the system and exec commands in order to actually execute the commands. Pay particular attention to the multi-argument forms of both those functions, and use them, if possible--they're more secure.

Also, read perlsec and run in taint mode (-T), and do security checks on the commands that the server receives.

IMHO with the information provided, it would be best to have the script on one server parse out the commands then do a form of remote command via ssh or kerberized (encrypted) rsh.

open(CMDS, "file_of_commands"); while (<CMDS>) { chomp; # ssh -l username machine "$_"; }
