I just did 'ssh' to one of the Linux hosts and when the connection was made, I 
got this:

Warning: No xauth data; using fake authentication data for X11 forwarding.

Does this possibly have something to do with the problem I mentioned in my 
initial post in this thread?  I am going to Google that error and see if I 
can find something.
