Ugh, that's the archaic, telnet epoch way of doing it. It doesn't work
on modern *nix systems for a number of good reasons:

-  there is no client-host authentication as to who gets access to your
X server, anyone can send a window and e.g. log everything you type in
your keyboard, including all of your bank accounts and passwords.

- there is no encryption, so anybody could tap into the connection. 

- the ports are likely blocked by firewalls.

Windows X servers (WinaXe for example) might still ask you whether to
accept such a connection, but really, DON'T USE THIS!

As Florian said, one just needs to use
 $ ssh -X server
This way everything is tunneled through SSH, it uses client-host
authentication, works on every system, can be easily tunneled,
can be compressed on slow connections (pass the -C option) and so on.
