Re: VNC - SSH / question, problem

Michael,

First let me appologize for being so dumb about this. I'm very new to SSH
and I figure I'm missing something here.
What you describe is what I'm trying to do. This is what I have done step
by step.

1. I have VNC & Cygwin SSH on WINXP pc 1. (CYGWIN sshd is running. Looks
like the srvany/firedaemon method is not needed or is it?) I also just
generated an RSA key for it but not sure how to get it to the registry.
2. I have SSH on WINME pc 2.
3. Run SSH on WINME with the parameters for fowarding: -L 5902:WINXP:5901
WINXP
4. I then run VNCviewer localhost:2 from WINME (connect to itself thinking
it will foward to WINXP).

Instead of the foward to WINXP, I get the double mirror effect.
Is this correct? Where am I going wrong?
Should step 4 be VNCviewer WINXP:1 ? If so, how do I know it's tunneling
through SSH?

I believe SSH is setup correctlyt on WINXP since I can go to a session and
perform the ssh-host-config.
SSH on the client side on WINME also executes.

Many Thanks.
Carl
