You need to have gdm, kdm or xdm running as an xdmcp server (on port
177) before this will work.

If you are starting from runlevel 3, then you might want to edit
/etc/X11/gdm/gdm.conf to change:

[xdmpc]
Enable=true

and then run the daemon manually (as root).

If already you boot at runlevel 5, then just enabling xdmpc will do
the trick.

If you don't want to run gdm (or whatever) on your local machine,
then later in the config file do this:

[servers]
#0=/usr/bin/X11/X
#1=/usr/bin/X11/X

That is, comment out both of these two lines (to force gdm to only
run on a network socket).

Modify any of this as appropriate for whatever display manager
daemon you want to use.

Hmm, if an xdm daemon wasn't running on the target machine then I'm
suprised that it didn't simply say "connection refused".

Oh, a warning: gdm uses tcp_wrappers, so make sure that the entries
in /etc/hosts.allow and /etc/hosts.deny protect the daemon but still
allow connections from your 10.102/8 network to work.
