Welcome to the Monastery, avatarengineer!

Can you describe in a bit more detail as to what you're trying to achieve? Are you wanting to write a script that can listen on multiple ports, and write/log information if those ports are touched? Or are you wanting to develop something that tries to 'see' when existing listening services receive requests and then logging that?

Beyond that, can you share what you've tried so far, or at minimum, show what/where you've researched?
