Can't connect to remote kernel on Mac OS 10.6

[Nate Dudenhoeffer]

I am running Mathematica 7.0, on Mac OS 10.5, running on a PPC processor. I
have no problem linking to kernels on other Macs similar to mine. I cannot
connect to a remote kernel on a 64bit Intel Mac running Mac OS 10.6 (Snow
Leopard). I can access the kernel in terminal with ssh
nate@IPAddress/Applications/Mathematica.app/Contents/MacOS/MathKernel.
But I cannot create a link from within Mathematica. I have tried a lot
of suggestions from various websites.

I reported this problem over a month ago to Wolfram (on a Premier
subscription account) and have not heard anything about what the
problem is or what the fix is. As far as I have been able to track it
down, it is a change in how Java and/or ssh behave under Snow Leopard.
I've found no solution either.

Thanks for the response Mike. I know that the handling of SSH is much more
restrictive in Snow Leopard. I have used a port monitor (linksnitch) to
monitor ports on one of my remote PPC machines, and it appears that I am
only using port 22 (standard SSH). Also I can launch to kernel remotely in
terminal, but can't create a link in mathematica. Which leads me to believe
that the problem is with Java. If you do get a solution with Wolfram,
please keep me informed.
