Hi.. I would really appreciate some help.
My office computer runs Win2K. (ip 128.220.18.11) I installed openssh
from www.networksimplicity.com I can ssh from my notebook (Mac
powerbook) into my office machine. I am also do the vncviewer into the
windows machine. However, I cannot use vncviewer via ssh into the
Win2K. I also cannot use the vncviewer via ssh into the Win2K from a
Linux machine. I suspect it is a problem with either the sshd server
on thw win2K or the vncserver on the win2K. I have already added the
'AllowLoopback' and 'LoopbackOnly' to the registry.

Here is what I did:
ssh -L 5900:128.20.18.11:5900 128.20.18.11 myname@128.220.18.11

The authentication goes through, i get a prompt telling me i am in
c:\openssh

Then I start "vncviewer localhost:0"
and nothing happens.
But in the ssh session, I see messages telling me "channel 2
:connection refused" as I start vncviewer.

Can some give me some guidance what to do?

Thanks in advance
