If you are running an Xserver with
export DISPLAY=WWW.XXX.YYY.ZZZ:0.0
it is possible to use another user's display to make your tasks appear there - simply by using their IP address.
This could be useful - but it can also be annoying when some abuse it.
An X server can use various methods to restrict clients. The simplist is xhost, which allows restriction by IP address. There is also what is called the MIT cookie mechanism, usually employed on workstations using XDM. Tell us a bit more about how your system is configured. -- Mark Evans St. Peter's CofE High School Phone: +44 1392 204764 X109 Fax: +44 1392 204763
