19.8 Summary
Remote access to the GNOME desktop environment of an Ubuntu system can be enabled by making use of Virtual Network Computing (VNC). Comprising the VNC server running on the remote server and a corresponding client on the local host, VNC allows remote access to multiple desktop instances running on the server.
The standard remote server solution for the GNOME desktop is Vino. Once installed, remote desktop sessions can be established from other Linux systems using a remote desktop viewer such as Remmina.
When connecting from non-Linux systems such as Windows or macOS, it is necessary to disable Vino’s encryption requirements. Once disabled, connections from client systems should be established using SSH tunneling.
When the VNC connection is being used over a public connection with Vino encryption disabled, the use of SSH tunneling is recommended when connecting to ensure that the communication between client and server is encrypted and secure.
