ReverseSSH

Following a Python networking tutorial found here: YouTube Playlist.

Reverse SSH allows one computer to establish a connection onto another computer, and gain control without necessarily having been given permission.

The server.py file runs first, listening for any connections. This server script is running on the host. When client.py runs (containing the ip address of the host), a connection is established. This connection is from the client to the host (Client -> Host). Using this connection in the other direction (Client <- Host) is why it's called Reverse SSH - we're reversing the initial SSH connection direction.

In our code, the server.py file contains s.accept() to accept new connections. This method returns a new Socket object [1], which contains a connection which the server can use to send data back to the client.

To summorise: a client connects to the server, the server uses this connection to send data back over that connection.
