How to kick everyone around you off wifi with Python


This script will find the most powerful wifi interface and turn on monitor mode. If a monitor mode interface is already up it will use the first one it finds instead. It will then start sequentially hopping channels 1 per second from channel 1 to 11 identifying all access points and clients connected to those access points. On the first pass through all the wifi channels it is only identifying targets. After that the 1sec per channel time limit is eliminated and channels are hopped as soon as the deauth packets finish sending. Note that it will still add clients and APs as it finds them after the first pass through.

Upon hopping to a new channel it will identify targets that are on that channel and send 1 deauth packet to the client from the AP, 1 deauth to the AP from the client, and 1 deauth to the AP destined for the broadcast address to deauth all clients connected to the AP. Many APs ignore deauths to broadcast addresses.

# Console colors
W  = '\033[0m'  # white (normal)
R  = '\033[31m' # red
G  = '\033[32m' # green
O  = '\033[33m' # orange
B  = '\033[34m' # blue
P  = '\033[35m' # purple
C  = '\033[36m' # cyan
GR = '\033[37m' # gray
T  = '\033[93m' # tan

Set up terminal colors. Not perfect since some different terminal setups may break the colors but I can’t find a common setup that this doesn’t work with… yet.

How to measure packets per second or throughput on high speed network interface – Xmodulo

There are many traffic monitoring tools available on Linux, which can monitor/classify network traffic, and report real-time traffic statistics in fancy user interfaces. Most of these tools (e.g., ntopng, iftop) are powered by libpcap, which is a packet capture library used to monitor network traffic in user space. Despite their versatility, however,libpcap-based network monitoring tools cannot scale to handle traffic on multi Gigabit rate network interfaces, due to the overhead associated with user-space packet capture.

In this tutorial, I will present simple shell scripts that can monitor network traffic on per-interface basis, without relying on slow libpcap library. These scripts are fast enough to support multi Gigabit rates, but only suitable if you are interested in “aggregate” network statistics on per interface basis.

The secret for the scripts lies in sysfs virtual filesystem which is used by the kernel to export device- or driver-related information to user space. Network interface related statistics are exported via /sys/class/net/<ethX>/statistics.
