(see security groups for more information). VNC for Ubuntu is a great tool to have, especially if you’re constantly working on or supporting several devices. Once you are connected to your VNC server using an SSH tunnel, you no longer require port 5901 open so it is recommended that you remove this rule from your security groups. Your GUI desktop for your remote session should now open.In the VNC server field enter: localhost:5901.ssh -i /.ssh/ubuntu18.04 -L 5901:127.0.0.1:5901 -N -f -l tecmint 192.168.56.108 Next install vncviewer client such as TigerVNC Viewer as follow s (you can install any other client of your choice). Type the following in your local terminal: SSH -i filepathtoyoursshkey/sshprivatekeyfile.key -L5901:localhost:5901 Start your VNC viewer. On Linux client machine, open a new terminal window and run the following command to create an SSH tunnel to VNC server.There is an example of creating an SSH tunnel to a VNC server running on a compute node of one of our clusters.īelow are instructions for connecting using an SSH tunnel for linux or mac: Connect using an SSH tunnel (see SSH_tunnelling).If you are confident in your ability to setup an SSH tunnel, you may skip this step. This is only meant to test your server-client connection before connecting securely with an SSH tunnel (the next step). Step 1: Create a New xstartup Configuration File We’ll have to configure a new xstartup file, so let’s take a backup of the original: mv /.vnc/xstartup /.vnc/xstartup. However, this is not a secure connection data sent to and from your VM will not be encrypted. If you don’t already have a TightVNC VNC Server then you can follow our tutorial on How to Install VNC Server on Ubuntu 14.04 LTS. Test your connection by opening port 5901 (see security groups for more information about opening ports to your VMs with OpenStack) and connecting using a VNC viewer, for example TigerVNC.

The vncpasswd command can later be used to change your password. This password is used later when connecting to the vnc desktop.

The first time you start a vnc server it will ask you to set a password.
