All, I am new here. I am trying to get Cygwin working with XDMCP from a Windows 2000 workstation to a Redhat 7.2 server and I am getting the following error. Any Help would be greatly appreciated.. _XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root http://www.x10.com/friends/refer.cgi?lsmithjr@atl.mediaone.net
