VNC is a protocol where you use your keyboard/mouse/screen an mouse to monitor or control a remote system.
This document is a real-world implementation of the document(s) found at Archlinux Wiki - TigerVNC.
NOTE: The setup is not implementing any VNC encryption so SSH will be used to establish the connection.
The benefit of using SSH is that you can easily adapt this to target any remote server.
On the system to be controlled install package
Replace the phrase
$USERNAME with the username of the actual user you want to configure.
Create the file
~/$USERNAME/.vnc/config with content (replace session according to your installation)
session=openbox geometry=1400x900 localhost dpi=96
Create a password for the user using
/etc/tigervnc/vncserver.users and append
Start a vncserver at the selected display
systemctl enable --now vncserver@:2
Install the package
SSH provides a secure channel and using key based authentication is the recommended method.
Open a ssh connection using port mapping
ssh $USERNAME@client -L 9902:localhost:5902
Then launch the VNC viewer and input the following connection details then click connect
Input the password created earlier (ignore the warning as we are using an encrypted connection) and you will see the remote system.
