probemon

A simple command line tool for monitoring and logging 802.11 probe frames

I decided to build this simple python script using scapy so that I could record 802.11 probe frames over a long period of time. This was specifically useful in my use case: proving that a person or device was present at a given location at a given time.

Usage

usage: probemon.py [-h] [-i INTERFACE] [-t TIME] [-o OUTPUT] [-b MAX_BYTES]
                   [-c MAX_BACKUPS] [-d DELIMITER] [-f] [-s]
