On my Computer I have installed a standard SuSE Linux 8.1 Pro with Grafik-Login. I want to detach the binding of my X-Server to an IP-Socket or restirct it to some IP-Adresses (localhost, ...)

In the config-file "/etc/X11/xdm/XServers" I have changed ":0 local /usr/X11R6/bin/X :0 vt07" to ":0 local /usr/X11R6/bin/X :0 vt07 -nolisten tcp". But nothing happens. After a reboot the X-Server ist still listening on port 6000.

Aehm, die you really reboot? Not just log out? I do exactly the same thing with my setup here, and I've never seen a problem with it.

Does any one knows how I can solve the problem?

Please type "sync", hit the reset button and see again with

netstat -anp|grep LISTEN

Basically, you'd have to restart xdm/kdm to make this work. You can do so by running

rcxdm stop sleep 10 rcxdm start

as root.
