Yep. Pretty weird! You would think that if ssh had a problem it
would show up elsewhere,
too.
Other datapoints:
3) The "BadAtom" happens on commands to the window manager, e.g,.
"xwininfo"
- Also on TclTk, which uses X11 server atoms for IPC
- Regular screen traffic seems unaffected
(i.e., "xwininfo" would be a good tool for testing this bug)
4) FreeBSD 5.3 likes ssh tunneling just fine.
5) Sun users have reported a similar problem. There is a decent
chance that
their version of ssh is somewhat old, like FreeBSD 4.2
6) Pre-Tiger, FreeBSD 4.2 liked ssh tunneling just fine, too.
So it seems that there was a change, perhaps inadvertent, to ssh
that was not entirely
compatible with older ssh servers. New ssh clients talk to new
servers just fine,
old ssh clients talked to old servers just fine, but new clients
talking to old servers
cause X protocol screw-ups.
Since Mac OS, FreeBSD, and probably Sun all use ssh from the same
open-source code
base, I think this is an issue with that code base and has nothing
to do with Apple.
If so, it should show up elsewhere, e.g., old Sun app talking to a
fresh Linux
console. Anyone have the setup to test this assumption?
Have you tried the -Y option to ssh?
Nope. My read is that's just authorization which isn't the issue
here. Also, as soon
as I got my tools to work, I got on to paying work :-).

You NEED to try this option. It sounds EXACTLY like a security
problem to me. Every X client that connects to your Mac OS X box is
assumed to be "untrusted" unless you use -Y to circumvent this. Only
"trusted" clients can do certain actions. The error messages I have
seen caused by this include "OpenGL is not installed", which you
wouldn't connect with security either unless you understand what's
going on.
