This is a piece of glueware that sticks up different components from hardware detection to real-time web display.
USAGE:
echo "input" | python parser.py
or, better yet if airodump-ng available
airodum-ng <necessary args> | python parser.py
This script will print out all parsed source and dest MAC address. I'm currently working to send those information to a mysql database and then display it in real time (via php or ios app).
