As someone else said, why not use SSH? The r tools use a low numbered source port as a crude sort of authentication in addition to the .rhosts stuff. I seem to remember something about the rsh server connecting back to the client for stderr, though. That might be the port 1023 you're talking about. I don't know if it needs just 1023 or if other ports would be needed by more than one rsh connection. -- Michael Wood [EMAIL PROTECTED]
