Multi thread Python program(Stable, Persistence) that will make a Reverse TCP connection and grant Command line to the pc.

Need a client and server scripts written in python. The server script dont need to be compiled to exe. It will run on linux. All the server script do, is wait for a connection from the client. The client script need to be compiled to exe with the Freeze_cx (I will explain why). The client should be stable and make reverse connection, it should give me a command line on the pc it ran. I need the connection to be very stable. I been using this script the same way [login to view URL] Its not stable enough. And i don't have the option to run the server script from another terminal on linux, and intercept more incoming connections. Ounce i run the server script i need to exit the connection from PC-1 for example and then log to PC-2. And i might lose the other connections.
