Once authenticated, the ports will be forwarded and you can connect your VNC client to localhost:0 (or whatever screen number appropriate) and you should be good to go. When you want to perform an VNC over SSH connection, you would first need to connect to the SSH server. It also assumes that you have administrative privileges. It assumes that the remote system is running the OpenSSH SSH server and TigerVNC server and is configured with the IP address 192.168.56.100. When you are ready, click Open to connect to the remote system and create the session. In 7.10, I could use the command below to create an SSH tunnel and then VNC through it: ssh -L 5900:27.28.29.30:5900 ubs27.28.29. This recipe requires two systems, a CentOS system hosting the VNC server (remote system) and a local computer with a VNC client to connect to it. This will save time if you want to use this configuration again in the future. This is only normally used when connections are to tunnelled through a custom. You can name and save this configuration from the Session screen. In the Sessions configuration screen, specify the host name ( in this example). In this case, you can use either the name of the remote host or ‘localhost’ in the destination field. It is valid for the VNC server to be the same system you are connecting to by ssh. Because this is a local forwarding, the source port can be accessed later as localhost:5900. Repeat as desired although only one port forwarding is required to use VNC. This will add it to the list of forwarded ports. For each VNC port you want to forward, you need to add a Local forwarded port.īy default, VNC screen :0 uses port 5900/tcp, screen :1 uses 5901/tcp, etc.įor each port you want to forward, in the Port forwarding section enter:ĭestination: :5900Īnd click Add. On your local system, start putty and in the configuration window click on Tunnels under the SSH menu. Once the VNC connection is terminated logout or exit from the ssh session and the ssh tunnel is closed.

A normal VNC connection should be established to the remote system. The port number will follow the display indicated (5900+display). There are times when you need to remote into a Linux desktop. In this example, a VNC client on your local computer will connect to a remote VNC server (:0) using port forwarding with an SSH connection to another remote host (). Just change it to a ':1' to use 5901 as indicated in the second ssh example. If your network doesn't allow connections into the default VNC port 5901, you can tunnel it through SSH. Using tunnels with SSH is a powerful method to access services on systems behind a firewall or that are otherwise inaccessible.
