X Listening

Hi Anyone know how to stop X-windows and port 6000 from listening on SuSE 8.2 ? I've already tried changed the line ... :0 local /usr/X11R6/bin/X :0 vt07 to :0 local /usr/X11R6/bin/X :0 vt07 --nolisten tcp but X-windows is still listening on port 6000. What else do I need to change ? Thanks -- Richard
