X / X11 forwarding over SSH - an alternative to remote desktop
The usual way to run remote systems graphically is through some kind of remote desktop service. Like VNC or remote desktop (RDP). An alternative way is X forwarding which forwards remote application windows over SSH and displays them on the local system. Example, with one Linux client and one Linux host: Host: /etc/ssh/sshd_config must contain X11Forwarding yes xauth must be installed (apt-get install xauth) Client: ~/.ssh/config. should contain: Compression yes ForwardX11 yes How to use: Login to the host as usual using SSH, for example: ssh examplehost -l username Add -X if you haven't added X11Forwarding yes to your local config file: ssh examplehost -X -l username Then run a desktop application, like mate-terminal on the host. The program will pop up on your local machine if everything works as expected. You may even start a full desktop session. For example, in MATE you run mate-session. Add -C for compression.

Multiple hosts and compression
To use multiple hosts and compression on some, do this in the config file: Host example.com Compression yes ForwardX11 yes Host * ForwardX11 no
