Configured?...... It just works like this. You imply some degree of 'control' and knowledge which I don't possess! Client is usually a PC from which the user makes a telnet sesssion to the LINUX box to start a task - and also runs an Xserver (the free MIX one) locally. We also use Acorn clients which connect via xdm. But anyone can seemingly 'send' tasks to the screen. On Mon 26 Mar, Mark Evans wrote:
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.
