Hi Don.
Sorry - my earlier explanation was poorly worded. Some clarification:
These aren't commands that get automatically executed at launch of X11.
They're simply quick ways for us to get an xterm window on a remote
machine. Your example of an ssh command is one I'd likely put into a
customized 'Applications' menu under X11. (Of course, then I'd have to
set up ssh on the Sun boxes...)
The first time I run X11 after boot, I can get a local xterm. I can
also use the 'Applications' menu items we have, and they work (i.e. the
new xterm window appears, mid-rlogin to the remote sun machine).
If I then quit and relaunch X11, I can still get local xterms. However,
the commands we've added to the 'Applications' menu no longer work - if
we use one, nothing apparently happens (no xterm window at all).
Hmmm...after restart, if I simply type the 'xterm ...' command in a
local xterm, it works (i.e. I get a new xterm window, prompting me for a
password on the remote sun machine.) Hmmm...
Logout and login again doesn't make any difference. It seems to require
a reboot to restore the initial behaviour.
Funny that the commands in the menu work the first time X11 is launched
after boot, and not afterwards.
If I replace the '-exec rlogin <name>' with '-exec xclock', xclock
eventually appears on my display (along with the xterm window it was
launched from).
We actually use csh on the macs and suns - some of our software is
intended to run in csh, and consistency is a good thing.
I'll look into my environmental variables on local xterms some more.
Thanks!

Good thing you asked for suggestions, not solutions...
As far as I know, items in the 'Applications' menu don't automatically
get executed when X11.app is launched. But when you say "If we quit X11
and relaunch it, the xterm window no longer appears." it sounds as if
the you're saying the do get automatically executed. Is that the case?
In the context of my above question, are you sure that it is the command
in the Applications menu that isn't working? Do you have a similar one
in a .xinitrc file -- because one there would get executed at startup --
and maybe that's the command that only works the first time?
After you relaunch X11.app, can you start a local xterm?
If you can start a local xterm, what happens if you type that command in
it?
What if you logout and login instead of rebooting?
How about if you reverse the order -- rlogin first and then start an
xterm on the remote machine?
I do this with ssh, like this:
ssh -f -X remote.host xterm -bg lightsalmon -title WhatEver
If you never solve the problem, perhaps that would be an acceptable
work-around.
Have you checked all your environment variables in both contexts, and
compared them?
What if you change the -exec rlogin to something innocuous, such as
-exec xclock ?
(not that I expect that to reveal much, but if xclock works while rlogin
doesn't, that would seem to eliminate a whole class of causes)
10.2 is fairly old. Somewhere along the line Apple changed the default
shell from tcsh to some other shell (bash, I think), and if I remember
correctly, tcsh was still the default in 10.2 (but the memory is
definitely hazy). Check your shell initialization scripts.

Hi there.
We've just switched to using X11 on Tiger (10.4.2), having used OS X
10.2.n until now.
We use X11 to get access to a couple of Sun machines. We have
customized the 'Applications' menu in X11 with lines like:
so we end up with an xterm window rlogged in to the remote sun machine.
This used to work perfectly. Now, it works for only the first time we
run X11 on one of our new macs. If we quit X11 and relaunch it, the
xterm window no longer appears. A reboot fixes the problem temporarily.
Any suggestions?
Thanks,
Chris J.
