SIMPLE TCP TESTING TOOL

Simple tools to manually test socket programming project. Requires python3.

Features:

• Arguments can be inputted via command line arguments vs via interactive console
• Verbose mode vs silent mode
• SSL/TLS wrapped socket (optional)
• Does not require additional python module (only using socket, argparse, ssl, and sys)

Common Usage:

• python3 simple_tcp.py -s -p 3000: start server socket on port 3000 and accept connection from all interface
• python3 simple_tcp.py -c -h 192.168.1.20 -p 3000: connect to 192.168.1.20:3000
• python3 simple_tcp.py -i: interactive mode, the script will ask for host, port and mode interactively (easier for noobs)

Arguments:

• "-h"/"--help": display all command line arguments
• "-a"/"--host": (optional) set target host, ex: -a 192.168.137.20, will default to localhost if not set
• "-p"/"--port": (optional) set target port, ex: -p 8888, will default to 80 if not set
• "-b"/"--buffer": (optional) set buffer size, ex: -b 1024, will default to 4092 if not set
• flag mode: "-s"/"--server" or "-c"/"--client", can only choose one, will default to client mode if not set
• flag interactive: "-i"/"--interactive", ask for host, port, buffer, and mode interactively (automatically assumed if no arguments provided)
• flag verbose: "--verbose", display verbose output (useful for debugging)

SSL Arguments:

• flag ssl: "--ssl": add this flag to use ssl mode
• "--ssl_server_certificate": set path to ssl server certificate (for ssl server mode only)
• "--ssl_server_privatekey": set path to ssl server private key (for ssl server mode only)
• "--ssl_client_ca": set path to certificate authority (CA)'s certificate (for ssl client mode only)
