DECwindown v. X11 problem

[gerry at swift.cs.tcd.ie]

I have tried (without success) to run a simple "hello world" X
application on a 5810 running Ultrix V3 and "standard" MIT X with
the display on a 2100 running Ultrix V4 with DECwindows. It works
fine if the application is run on a 5820 running V4 with DECwindows.
I have placed entries for remote nodes in /etc/X0.hosts. What am I
doing wrong? We run KERBEROS, could this be part of the problem?
