So I did what you said.

ssh -p 14522 xubuntu.computer.dyndns -L 9000:127.0.0.1:5900

The router port 14522 points to the xubuntu computer port 22.

The terminal window asked for the PW and logged me in successfully.

I started Remote Desktop viewer and put in localhost for Host and 9000
for Port and the popup window said "Connection to host "localhost:9000"
was closed."

In the terminal window it said: "channel 3: open failed: connect failed:
Connection refused"

I did a find and it called it red.local so I used red.local for the Host
and 9000 for the Port.

It took a lot longer, 5-10 seconds, before "Connection to host
"red.local:9000" was closed."

There was no message in the terminal window this time.

Now what do I do? I am logged into the the remote server with ssh.
Which error log do I look at to try to get an idea what is going on?
Should I be looking at the local error log or the remote error log?

Could we be trying to get the router port 5900 not the Xubuntu computer?
The Xubuntu computer has an IP address behind the router of
192.168.1.65. But the terminal window is logged in. This is beyond my
current comprehension.


Thanks for the help.

That sounds like you don't have your VNC server running on your
Xubuntu machine. I'd double check that if I were you. I've got a
train to catch, but I'll look for a response later.

I'd avoid using 9000 if I were you:
http://isc.sans.edu/port.html?port=9000

Did you try as I'd suggested previously?

$ ssh -X <username>@<IPorHostname>

after logging in:

$ firefox

And from the remotes firefox go to the 2Wire and modify what you need.

You can also open the remote config:

$ vino-preferences

Don't forget to close it when you are finished. That way you needn't
worry about VNC responding to unwanted attempts when you're not around.

Using Ubuntu 11.04 I could select System -> Preferences -> Remote
Desktop. Where is the equivalent in Xubuntu 12.04, please.

You have to install a vnc server, xubuntu isn't bundled with one. x11vnc
is a good one.
