Note that this is a serious security risk running this command. It measn
that anyone can connect to your X server and listen for keybord events
and log usernames and passwords! If both client and server machine are
behind a firewall that prevents incoming connections on ports 6000
through 6063, then you are only at risk from machines inside your
firewall.

Doesn't the DISPLAY variable have to be in upper case? In bash shell, I
tend to use the following:

	export DISPLAY=niels:0.0
