I found a good article for those out there that are having difficulties in understanding what xdmcp is used for: http://www.rru.com/~meo/pubsntalks/xrj/xdm.html You must understand that each local client wishing to connect to a server that is logged into a remote host via xdmcp needs to pass a -auth %AUTHORITY_FILE% command line parameter, where %AUTHORITY_FILE% is a reference to your .Xauthority file for the current session. If you're logged into a remote host, it is fairly unlikely that you are going to have the %AUTHORITY_FILE% accesible on your local host. Harold
