Assignment for Networking 01 on the Hogeschool Rotterdam.

Usage

I used the following libraries

socket, threading, json, argparse, time

python3 main.py [-h] [--host HOST] [--port PORT] [--h2 H2] [--p2 P2] mode

The program can be run in different modes:

client1 or 1: Run as client1. This requires Client2 to be running already because Client2 initiates a socket server to which client1 connects

client2 or 2: Run as client2.

client1 or 1: Run automated. This creates 2 threads, client1 and client2. Both threads connect to the server. Client2 thread creates a socket server, to which client1 connects. After client1 has received data from the server it sends this data to client2 which than completes the request

When using 2 computers, make sure the port is opened in your firewall

Example Usages:

python3 main.py automated

$ python3 main.py automated
Automated testing. We setup 2 sockets to the target server(145.24.222.133:55550).
Client2 deploys a socket server and client1 connects to this server.
IP address for the server is just localhost, with port 55551
