pyportscan.py is a port scanner I created written in python. It uses a simple multi threaded technique and will try to connect to every port you define either range for -r option or specified ports using -s followed by port numbers separated by commas.

This program is intended for individuals or pentesters to test their network to automate the process of checking what ports are opened on a remote server.
