Forward graphical applications through ssh

It is possible to execute graphical applications on a remote machine and have their output showing on the local machine through a ssh connection.

Set up the server

Set up the server to permit X forwarding:

• Edit /etc/ssh/sshd_config
  • Set X11Forwarding yes
• service ssh reload
• apt install xauth

Connect from the client

• ssh -X {usual ssh connection parameters}: The flag -X enables X forwarding for this session
• Execute any graphical command

If you want to make X forwarding enabled by default for a certain connection, add ForwardX11 yes to the appropriate line in ~/.ssh/config
