I've the following two lines in Xaccess * LISTEN xx.xx.xx.xx where xx is the server ip. So it should give access to any server to xdm. I also notice these errors in xdm.log: xdm error (pid 9961): server open failed for myhost:0, giving up xdm error (pid 4191): Display myhost:0 cannot be opened xdm error (pid 4191): Display myhost:0 is being disabled where myhost is the nodename of L. I also realsed I might not need xdmcp, as I seem to be able to run graphical apps on S with ssh X11 forwarding. In which case all I need are the actual applications I run, e.g xterm or xpdf. So your initial responce to my question makes sense to me now. many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 928 8233 Fax: +44 (0)117 929 4423
