Trooper Proxy Chain is a module in charge of create a chain in the proxy communication.

Each middle chain has two processes and two ports: the ssh connection to the server with the specific port for the socket connection to the remote server and a local TCP server (other process and port).
The last chain has only one process and one port to connect to the final destination.
