Hi,
I have started some people off with Ubuntu Linux (as I use it myself) and I have setup their machines with an SSH server so I can remote login.

I can login and use VNC using windows from work but I just cannot seem to do it when I login via my ubuntu box.

When setting up SSH, i do this:

so now i expect any activity on port 5900 (VNC) on my machine to be forwarded to the remotely connected machine.

I then fire up terminal services (in Ubuntu) and start a VNC connection to localhost, but instead of the connection being forwarded to the remotely connected machine I just get a loopback to my machine.

i have also tried this line:

but this doesnt seem to work either.

Am I doing something wrong?? Any help much appreciated.

From what I can tell, it sounds like you've got a local vnc server running on your machine. If that's the case, it's taking precedence over the ssh forwarded port at the same number. Try forwarding a different port, e.g.
Also, some services won't like being contacted from 'localhost', so try it like above (i.e. with an explicit server name.

It's always good to run ssh with -vv to see what's going on when debugging this sort of thing.

Good luck.

Thanks alot for your help. I changed the port that SSH should listen for on my machine and then started vnc on the new port and it worked!!

You are also correct that I have a vnc server on my machine as well (i connect to it from work). I just assumed that if i setup SSH to fwd on port 5900 then my computer would ignore any requests to connect on the localhost on that port (seems to work in windows using putty) - would like to understand why it doesnt work in ubuntu.

Anyhow - again, thanks.
