Thanks! I installed the freenx-server on my wife's CentOS 5.1 and
nxclient on my F9. All works well, even running ssh on a non-standard
port.
The other way does not work, i.e. with freenx-server on my F9, trying to
connect from anywhere else. I configure the connection (correctly, as far
as I can tell), I try to log in, it connects but then gives me an error
message. I click on details and this is what I see:

want to try: ssh -X myserver; /usr/libexec/nx/nxnode --agent to test the
basic functionality. Session log follows:

The session file it's looking for is, as one might guess, in failed:

I'm not running selinux on F9 or any of my machines. I've looked at at
~/.nx/temp/12707/runlog and I have no idea what might be wrong. It's
rather long, but I'll post it in case someone is willing to take a look
at it. Thanks for any help.
