Hands-On Penetration Testing with Python

Building a network scanner with Python

Now that we are all set up with our VirtualBox image, let's have a look at a simple Python script that will help us to call Nmap and initiate a scan. Later on, we will optimize this script to make it better. We will finish by making it a full-fledged port scanning Python engine with pause, resume, and multiprocessing abilities:

The information produced by the preceding script is hard for the Python code to filter and store. If we want to store all the open ports and services in a dictionary, it would be hard to do that with the preceding method. Let's think about another way in which the information produced ...
