The question I posted to xperts and sun-managers was:
===========================================================================
I have a problem exchanging windows between a Silicon Graphics
Iris workstation and a SUN sparcstation 1 running Motif and openwindows
respectively. It is actually a one-way problem. Getting windows from the SUN
to display on the iris is no problem, but it doesn't work the other way round.
I have already tried starting up openwin with the '-noauth' option (which
disables MIT-MAGIC-COOKIE) and am sure I have set xhost and DISPLAY
appropriately.
The error message I keep getting from the iris is:
--- iris1 12# dgl error (TCP connect): Connection refused dgl error (default init): default dglopen(sun1.lett.kun.nl:0.0,4) returned -127 ---I am not really sure what the problem really is, the first line suggests security, the second something about the graphics library on the iris - the SUN only has a monochrome display.
Any potentially useful hint would be appreciated. ===========================================================================
SOLUTION:
The problem was not authorization but dgl stuff that I don't have on the SUN, this became clear when I started an xterm instead of an SGI application - it worked perfectly (why couldn't I work this out myself???).
Thanks to everyone who send a suggestion, I just include all suggestions here.

This is easy...you tried to start a _GL_ application and have it display on your Sun, which does not have Distributed GL support!
Many neat SGI supplied tools use GL, not vanilla X :-(

Don't know anything about the SGI window mgr but your problem sounds similar to one I had between Sun and DEC stations.
DECterm could display on Sun but cmdtool could not display on DEC.
To make sure it is not purely an X auth problem, find a copy of xterm for SGI and try to display it on the Sun. If this works, then auth is not the problem.
What I expect is that you will need to find out what _extra_ Motif libraries your SGI app is using and get the appropriate support libraries for the Sun.

It looks like the application you are trying to start is expecting to use GL to draw graphics, and since you are not using the local display on the iris then it is looking for a GL server on the remote machine. Does the SUN have a GL server running? If not, then you can't run this application remotely.

try using the IP number rather than name in your display info. I have to do that on my Sun's to get the application to display properly.
