The VNC viewer will then ask for your user/password to connect to the VNC server, after which the connection to the remote desktop will be complete. With the tunnel created we can now use a VNC viewer to connect to localhost:1, which is the local endpoint of the SSH tunnel (VNC display :1 will get translated into port 5901). Leave the terminal window with the tunnel command open, as closing it will also close the SSH tunnel. In most cases TCP port 5901 needs to be tunneled, which corresponds to VNC display :1 (port 5902 would correspond to display :2, etc).Īfter executing the command above the SSH tunnel will have been set up and you will be logged into one of the login nodes. To test which keyboard layout is active, you can enter a few test characters at the login prompt and remove them again before entering your actual login name.Workstation$ ssh -L 5901:r34n4:5901 uses the ssh command to set up an encrypted tunnel that forwards TCP port 5901 on your local machine to port 5901 on the GPU node r34n4 on Lisa, using the interactive visualization node as access point. Also look out for your keyboard layout to prevent any mishaps during the login (Y and Z might be switched due to a different keyboard layout). Please keep in mind to always check your spelling since the VNC login is case sensitive. Access Customer Control Panel’s page of your instance > Manage > VNC Password: Then find the server you’re trying to connect to and copy-paste the VNC credentials.Īfter entering this information, please press the connect button and type in your VNC password.Ĭontabo customers can easily change the VNC password. In case you’re a Contabo customer, just login to Customer Control Panel and click on Your services page. Contact your provider if not sure about the credentials. The standard port number is 5900, although it may change depending on your server setup. Now prepare your login credentials for VNC. Our customers can use VNC when working with their virtual instance, VPS or VDS. That being said, VNC can be invaluable in a situation when you can’t connect to your server using standard methods. Remote Framebuffer protocol was built as an easy solution to a wide variety of systems and configurations, allowing greater capability than older protocols.Īlthough easy to set up and use, VNC is lacking in security in comparison to mainstream protocols, such as SSH or Windows Remote Desktop. The transmission itself uses open-source Remote Framebuffer protocol, compatible with operating systems such as macOS, Windows and Linux. It’s typically used to control your remote instance via graphical interface, meaning you use your local keyboard and mouse to work on a remote computer. VNC or Virtual Network Computing is a platform allowing you to control a remote computer, server or other device. In this guide I will show you how to connect to your VPS (or any server) using VNC.
