SSH

The most common approach to visualization is by initiating an SSH connection with the ForwardX11 flag set. The most common flags are:

ssh -X someone@something.ip.address #ForwardX11
ssh -Y someone@something.ip.address #ForwardX11Trusted
ssh -XY somone@something.ip.address #ForwardX11 ForwardX11Trusted 

This method can be used on Linux, MacOS(with XQuartz) and Windows(with Xming). However, a more practically useful method is to modify the ssh configuration file itself. The following snippet can be added:

Host *
  ForwardAgent yes
  ForwardX11 yes
  ForwardX11Trusted yes
  XAuthLocation /opt/X11/bin/xauth # For a Mac with XQuartz

For Linux (and Windows with WSL 2) machines, which xauth will provide the path for the XAuthLocation variable. Now the user is free to connect directly:

ssh someone@something.ip.address # Reads the ssh configuration

A quick test to see if X forwarding is working is to type

xclock

which should open up a small clock gui showing the local time.
