Hi,

Thanks for the reply, see below.
 

Sounds like you're setting DISPLAY on anywhere.com to the value that
only works locally on Leopard.  Don't do that.  Nothing in the login
scripts on anywhere.com should touch the DISPLAY value.  Let sshd set
it and forget it.

No, that isn't the problem, the DISPLAY variable is set correctly:

anywhere:> echo $DISPLAY
localhost:14.0

I haven't changed the DISPLAY variable on the remotehost. This worked until I upgraded to Leopard.

What version of ssh are you using on the local machine? (Try `which ssh` to see if you're getting something like a Fink-installed /sw/bin/ssh.)

Leopard's ssh has extra code to deal with Leopard's DISPLAY value (which looks like "/tmp/launch-nnnnnn/:0"). I could imagine other versions of ssh printing that error when used from Leopard.
