rsh and rlogin use two different ports (513, 514), check whether the
appropriate holes are in your server firewall (/etc/syconfig/iptables).
Then make sure the client accepts the callback traffic (on some random
port) from the server.
And then forget about it and use ssh :-) , unless you'll never have any
untrusted machine on your network..
Cheers
