Subject: Re: ssh tcp forwarding

One thing on the port forwarding.  You really should make the 
host between the two ports be 'localhost'.  Otherwise, if you have
firewalls inbetween, this will never work (BTW, vnc works fine 
over ssh, but I think you will get confused if you have a VNC server
running on the same machine you are trying to run the client on,
as both the server, and the ssh port forwarding will be listening
on port 5900.  I use the following line to get away from this:
-L 5904:localhost:5932 home
Then I always fire up my VNC session @ home on server :32
and I do a connect via localhost:4

HTH....
