While SSH is a powerful tool for controlling a computer remotely, not all applications can be run over the command line. Some apps (like Firefox) and hacking tools (like Airgeddon) require opening multiple X windows to function, which can be accomplished by taking advantage of built-in graphical X forwarding for SSH.
SSH, or the secure shell, is the de-facto way or accessing a computer remotely, allowing anyone to log in and administer a computer over a local or remote network. Many useful apps can be controlled this way, but those requiring an interactive window aren't able to open when summoned over SSH. To make this happen, we'll need to forward the data from the remote computer to a server running on our local machine, which will display the remote application in a window on our local screen.
What Can't You Do Without x11 Forwarding
Most hackers are familiar with the basic use of SSH for everything from accessing your Linux system remotely to transferring files over a network. For command-line applications, SSH can give you complete control without any modifications, running programs like Besside-ng, Bettercap, and Kismet without any issues.
The limitations of SSH become clear as soon as we try to do something like run Airgeddon, which requires multiple windows to open and execute programs to feed data back to the main program. Without launching these programs in additional graphical windows, Airgeddon won't work, making it seemingly useless for a hacker with only a remote SSH connection.
