Ah, thank you. > At least on my Debian "hamm" system, the unix-domain socket used by X11 > is /tmp/.X11-unix/X0 Ah, hidden things surprise me then and when.

My matn concern is that everyone can connect a viewer to the server, just by guessing a 6 to 8 character password encrypted by a fixed key DES algorithm. The key is plain visible in the source code. And connecting a viewer without -shared option will probably terminate every other viewer session. This is sooo bad. I still cannot see all the implications (as there is domain socket, TCP and RFB ((used by VNC)) protocolls now), but it is much clearer now. Thank you! Marcus -- "Rhubarb is no Egyptian god."
