UltraVNC Repeater + SSH tunneling

Post by hathanassiou »

Has anybody tried to use SSH tunneling to the VNC repeater to create a secure VNC connection? Would that be more secure than the DSM plugin?

The tunnel would look like:
UltraVNC (viewer) -> PuTTY -> ..... -> OpenSSH server -> UltraVNC Repeater -> UltraVNC (server).
Or the Stunnel could be used instead of SSH.

Would that work?

Thanks for all your incredible work

Yes, it would. I'm doing sth similar at several customer locations with firewalls, that do not allow outgoing connections on port 5900. Most times they allow ssh outgoing and incoming, so I log on to the fw or border gateway and create a ssh tunnel to our corporate fw system to access an internal windows machine. So it looks like:
Client --- BorderGateway ====SSHTUNNEL==== Firewall --- int. Machine

- normal connection
= secure connection
Of course, you can use PuTTY for creating a tunnel on localhost, too. That would look like:
Client === FW/BG ====SSH TUNNEL==== FW/BG --- VNC Host

Is the Stunnel or the SSH better for performance and key infrastructure?
