You know you can do this with SSH and host keys, right? It's a more 
secure than doing stuff via rsh.

Just do the following:

1. Uncomment "PermitRootLogin without-password" in /etc/ssh/sshd_config.
2. As root run ssh-keygen, pick your cypher and password, and then put 
it in .ssh/authorized_keys on the remote host.
3. Restart the serving host's sshd using /etc/rc.d/sshd restart.

Voila. Much better than using rsh.

(I admit I skipped or glossed over a few steps, but if you want more 
information they're available in the manpages :)..).
