There is no outbound filtering on the script, only inbound, so the 
problem lies at the server end.

Set up an RSA keypair with no passphrase (and guard the private end with 
your life since it's not encrypted), and you can use SSH, which is MUCH 
MUCH more secure than rsh as rsh uses IP based authentication, which is 
trivial to bypass in many situations.
