Any number of clients can connect to a vncserver. A simple example is given below where vncserver is running on It is expected that the user has access to this file on the server through SSH or through physical access. In either case, place that file on the client's file system in a safe location, i. For servers offering SSH connection, an advantage of this method is that it is not necessary to open any other port than the already opened SSH port to the outside, since the VNC traffic is tunneled through the SSH port.

For example:. Make sure to Start or Restart the vncserver. The VNC server has been setup on the remote machine to only accept local connections. Now, the client must open a secure shell with the remote machine Once connected via SSH, leave this shell window open since it is acting as the secured tunnel with the server.

Alternatively, directly run SSH in the background using the -f option. On the client side, to connect via this encrypted tunnel, point the vncviewer to the forwarded client port on the localhost. What happens in practice is that the vncviewer connects locally to port which is tunneled to the server's localhost port The connection is established to the right port within the secure shell.

What it does is that the -f switch will make ssh go in the background, it will still be alive executing sleep Notice the double colon — vncviewer's syntax is [host]:[display ] or [host]::[port]. In ConnectBot , connect to the desired machine. Tap the options key, select Port Forwards and add a port:. Tested with Remmina.

Issuing x certificates is beyond the scope of this guide. However, Let's Encrypt provides an easy way to do so. Alternatively, one can issue certificates using OpenSSL , share the public key with the client and specify it with the -XCA parameter. An example is given below the server is running on The VNC protocol currently only uses 7 mouse buttons left, middle, right, scroll up, scroll down, scroll left, scroll right which means if your mouse has a back and a forward button these are not usable and input will be ignored.

Optionally xte found in xautomation and xbindkeys can be used on the server to map the keyboard key presses back to mouse button clicks if needed. Install evrouter AUR and xautomation on the client. Configure evrouter, see Mouse buttons evrouter and evrouter man pages for instructions and tips on how to find the correct device name, window name, button names etc.

Example config:. Start evrouter on the client. With above configuration keyboard key XF86Back is sent to the VNC server when clicking the back button on the mouse, and XF86Forward is sent when clicking the forward button. If needed it is possible to map the keyboard keys back to mouse button clicks on the server.

In this case it might be a good idea to use keyboard keys which are never on the client or server. Install xautomation and xbindkeys on the server. This is a known issue introduced upstream. Most probably this is due to the application strictly requiring the composite Xorg extension. For example webkit based app: midori, psi-plus, etc. Verify that the user is not logged into a physical X session, unless this option was configured with x0vncserver.

See Section 9. Leave the remaining lines of the file unmodified. The -geometry argument specifies the size of the VNC desktop to be created; by default, it is set to x Set the password for the user or users defined in the configuration file. Note that you need to switch from root to USER first.

The stored password is not encrypted; anyone who has access to the password file can find the plain-text password. Proceed to Section 9. If you want to configure more than one user on the same machine, create different template-type service files, one for each user. In both these files substitute USER with the correct user name. Starting VNC Server. To start or enable the service, specify the display number directly in the command. The file configured above in Procedure 9.
