Hello: Which socket numbers does X11 use for client-server communication? I am assuming this is socket based communication, is this correct? Are a "group" reserved for this purpose? If so where is this written down?

Which socket numbers does X11 use for client-server communication? I don't know what a "socket number" is. When using X11 over TCP, TCP port (6000 + N) is used, where N is the display number. I forget exactly how many were registered with the TCP authority. If so where is this written down? See the Connection Setup section of the protocol specification (page 553 in the DP book).

To the best of my knowledge, the Server and Clients make _initial_ contact over the "well-known tcp ports" 6000 + n where n equals your display number (eg, foo:0.0 uses port 6000, foo:3.4 uses port 6003). Once the initial connection and verifications are made, a unique port is agreed upon (how, I'm not sure) for further server/client communications on a per client basis. > Alan Thomas Gilg tomg@cv.hp.com
