Is there a reason you must use rsh? Are you using rsync perhaps? If so
you can probably use SSH and make that passwordless using public/private
keys. SSH comes enabled and ready by default on almost every OS you’ll
find (need to open the TCP port in the firewall) and you can use rsync
with the SSH command to do what you are after. SSH is also secure where
rsh is completely open to the world.
Good luck.
