Use ssh's -X flag:
somehost> ssh -X user@remotemachine
remotemachine> echo $DISPLAY
somehost.example.com:10.0
remotemachine> xclock &
Don't forget to enable X forwarding in /etc/ssh/sshd_config:
X11Forwarding yes

ssh X11 forwarding is much more secure than DISPLAY/xhosts/xdm etc...,
because:
1. Your X11 server doesn't have to listen to port 6000
(You don't have to add '-listen_tcp' to startx command)
2. The communication between server and client is encrypted
Of course, YMMV.
