Maybe you've got the OS X firewall configured to prevent
connections to
port 6666? That doesn't seem to be default, because I didn't have to
adjust the firewall for my experiment.
Another possibility is that the ssh daemon on the linux box is
restricted from opening local connections. It wouldn't surprise
me if this is disabled by default by SELinux for instance :-(

I am still puzzled. I don't think it is a postgresql problem since I
can't forward to other daemons running on the linux box.
I have noticed a error in the message file on the linux box that
is generated when ever I try to connect from the mac.

It appears that I have to somehow tell the linux box about the Mac....
This does not appear to be necessary when talking to the mac from the
linux box.
Sigh,
