Scapy/Wifi Database

Overview

This page covers the use of Scapy to monitor wifi channels and populate a database with observations. These observations are completely passive and are at the physical layer (hardware) only. No network traffic.

Here's how this script is going to break down:

• Functions to deal with getting wifi card information, turning it off and on, and putting it in monitor mode
• Functions to define channel hopping behavior
• Functions to filter and print out information
• Function that handles each packet
• Functions to deal with new access points and new clients
• Main function

These functions will all be assembled into a script that we'll be able to run, and have Scapy monitor the packets coming in through a wifi interface and assemble a database of wifi observations directly from those packets.
