python_samples

Simple project with samples written in Python.

Current features

Server: receives connections on port 1234 and resend the content to a mirror server Mirror server: receives connections on port 4321 Client: sends connections request to port 1234

Running

Run both servers first to enable the listening on ports. Client server simply makes a request and receives a response. Therefore, should be run after servers are listening.

In different processes (terminal tabs, for example), run:

$ python server_socket.py

$ python mirror_socket.py

$ python client_socket.py

Future features

• error handling: code assumes every host is connected and responds correctly
• response length: code assumes a maximum of 64 bytes, but a dynamic header with message length should be provided.
• threaded servers: main server and mirror server run only one thread, but a high request period would take the system down.
• end of program: main server should end if received a "end of file" request or something similar.
• configuration: most parameters (ip addresses, ports, messages) are fixed.

Other enhancements

• methods descriptions: comment major methods to quickly understand their behaviour.
• software testing: add automated software testing
