Unfortunately I am not using XDMCP. I am logging in to my RedHat box on
the console under X11, then telneting to a remote box and trying to
display a client on my machine.

This was exactly my problem. ``/etc/init.d/ipchains status'' output
included the following:
Chain input (policy ACCEPT):
target prot opt source destination ports
REJECT tcp -y---- 0.0.0.0/0 0.0.0.0/0 * -> 6000:6009
I commented out the relevant line from /etc/sysconfig/ipchains and
reload the firewall rules with ``/etc/init.d/ipchains restart''.
Incomings X11 connections now work.
Thanks,
Mike
