Python Penetration Testing Cookbook

How to do it...

We can create a simple port scanner with the socket module, following are the steps:

1. Create a new file called port-scanner.py and open it in your editor.
2. Import the required modules, as follows:

import socket,sys,os 

Import the socket module along with the sys and os modules

3. Now we can define the variables for our scanner:

host = 'example.com' 
open_ports =[] 
start_port = 1 
end_port = 10 

Here we define the starting and ending ports that we plan to scan

4. Get the IP from the domain name:

ip = socket.gethostbyname(host) 

Here we use the gethostbyname method in the socket module. This will return the IP of the domain

5. Now we can write a function to probe the port:

def probe_port(host, port, result = 1): try: sockObj = socket.socket(socket.AF_INET, ...
