Today I reconfigured one of my servers, and it’s a note about how to run remote application from your desktop by using X11 and ssh..

My home system is running on KUbuntu, and the local server is running on LUbuntu.

LUbuntu (remote machine)

First of all, you need to install SSH server on the remote machine.

$ sudo apt install openssh-server
$ systemctl enable ssh
$ systemctl start ssh

The further SSH server configuration is out of scope of this article, but you can use this link as a reference https://documentation.ubuntu.com/server/how-to/security/openssh-server/index.html

KUbuntu (local machine)

Login via SSH with the -X parameter, and user and IP of the machine, eg

$ ssh -X user@192.168.100.222

Now run the application from the remote machine. It will be shown on your desktop. For example terminal

$ qterminal
