I've turned off the firewall and disabled the hosts.allow system on both abc and the remote system. I've tried different remote systems, different versions of vncserver and vncviewer. To use an ssh tunnel, we must start the vnc server using ssh, with this command (this assumes that the default port is used): ssh -t -L 5900:localhost:5900 remote-machine 'x11vnc -localhost -display :0' You are probably familiar with ssh, but let’s analyze this command.

We will also show you how to securely connect to the VNC server through an SSH tunnel. Huh?!? After days of trying to figure this out, I'm stuck. This guide covers the steps necessary for installing and configuring a VNC server on Ubuntu 18.04. So the next day, I changed back to the original ISP and router, and it still didn't work. Too bad because I had it set up nicely with the ssh-tunnel and all.

Been through this with TightVNC when I realised the TightVNC server only supports virtual desktops. If you can for example from 'client' login with SSH on 'server' as user 'woof' you on 'client' create an SSH-tunnel from 'localhost:5900' to 'server:5900', i.e. If x11vnc doesn't work well I will have to hope I can restore RealVNC. So as to SSH-tunnel the VNC connection you need to create that tunnel. I changed ISPs and routers, and it stopped working. Installing x11vnc will get RealVNC uninstalled. edit file/usr/share/applications/hildon/sktopso that it will launch your new python script /usr/bin/myx11vnc.py instead of original /usr/bin/x11vnc.I have been using vnc through a ssh tunnel for years successfully, that is until about a week ago.

VNC client software (it will be part of the package for the TightVNC installer).

PuTTY client on the client computer ( ).

VNC server software running on the host computer(in this case we will be using TightVNC : ).

OpenSSH server on the host computer ( ).

To tunnel VNC traffic over SSH, the following requirements need to be met : So in order to make it secure with encryption, we would need to tunnel traffic over SSH. ssh -L 61000:localhost:5901 -N -l username VNCserverIP. It connects port 61000 on the local machine to port 5901 on the server via an SSH tunnel. By default, RFB is not a secure protocol. The following command must be run on the client computer from which you are connecting to the VNC server. It uses Remote Frame Buffer(RFB) protocol to remotely control another computer. VNC as we know is a graphical desktop sharing system. I have a VNC server (x11vnc) configured to allow me to log into the machine at the local display (:0) via SSH tunnel, following the instructions here. Why would you want to tunnel VNC traffic over SSH?
