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
