VNC through SSH gateway

emdiesse · 03-04-2014, 11:32 AM

I am trying to connect from a windows or linux machine ('Laptop') through a SSH server ('Server') to a VNC server ('Desktop').

I have attached a diagram which best demonstrates exactly what I am trying to achieve

What I have tried so far is this:

[emdiesse@Laptop]$: ssh home.net
emdiesse@Server password:*****

[emdiesse@Server]$: ssh -L 5901:localhost:5901 Desktop
emdiesse@Desktop password:*****

[emdiesse@Desktop]$:vncserver
New 'X' desktop is Desktop:1

[emdiesse@Laptop]$: vncviewer home.net:5901

Error in TightVNCViewer: No connection could be made because the target machine actively refused it

I have port forwarding set up on my router for SSH (22) and VNC (5901) going to my Server

So, now I'm a bit stuck

Does any of this make any sense and am I doing anything right, what next?

Thanks

Yes and no...

You should be able to find lots of examples on how to ssh tunnel to another server.
What is home.net? dynamic DNS hostname?

You will need to foward port 22 from the router to your ssh server.

ssh -L 5901:vncserver:5901 username@home.net

Start vncviewer on the laptop and select localhost as the server.

ssh -L 5901:vncserver:5901 username@ssh-server

vncviewer localhost

Sorry, home.net is dynamic dns (well, an example)

I have just tried:
ssh -L 5901:vncserver:5901 username@ssh-server
vncviewer localhost::5901

and it works

Thank you very much.
