This port is referred to as If you create additional VNC server instances, they will be presented as port as :2 , port as :3 , and so on. Up to this point, our VNC server is up and running. Now we need to configure the commands that will be executed by the server every time we start a VNCV instance.

Execute the command below:. If another instance were running on another port, say or , we would execute the commands vcnserver -kill :2 and vncserver -kill :3 , respectively. To configure VNC, we will need to create a file called xstartup file in the. Execute the commands below:.

That ensures that the VNC server only accepts connections incoming from the server where it is installed. To get around this and connect to the VNC server from our local machine, we will establish an SSH tunnel from our local machine to the server. That is also an additional layer of security as only users with SSH access to the server can connect to the VNC server.

You can choose whichever one you prefer. On Windows you can use PowerShell or a terminal emulator such as Cmder. In my case, I will execute the command below:. Alternatively; you can add a -f argument which runs SSH tunneling in the background. Now to connect securely to your VNC server, launch the VNC client application and connect with the address localhost :.

If you are connecting to your server using Putty, create an SSH tunnel using the procedure below. On the left side of the Putty window, scroll down and get to the SSH option. Extend it and select the Tunnels option. Enter the details as shown in the image below—Port as the source port and localhost as the destination address. We will also use systemd to launch our VNC server on boot. With that done, we can now start, stop and restart our VNC server as a system service.
