A python3 wrapper around libsniff

Project description




I wanted to have a nice cython/python wrapper around libsniff. This name might confuse you, I just care about sniffing wifi packets from a nic in monitor mode.


pip install libsniffpy


Simple: Low level usage

from sniff import get_socket

# You might have to adjust 
s = get_socket("wlan0mon")
# or whatever big number, forgot how big those frames are lel
raw = s.recv(3000)

Advanced: Iterate over the Radiotap frames

from sniff import get_socket, type_predicate, subtype_predicate, loop
from sys import stderr
from dpkt import ieee80211
from dpkt.radiotap import Radiotap

if __name__ == "__main__":
    mgmt_predicate = type_predicate(ieee80211.MGMT_TYPE)
    probe_request_predicate = subtype_predicate(ieee80211.M_PROBE_REQ)

    mgmt_packets = filter(mgmt_predicate, loop("wlan0mon"))
    probe_requests = filter(probe_request_predicate, mgmt_packets)
    for pkg in probe_requests:

Guidance for n00bs

This lib opens a raw socket for a monitor mode enabled interface. It needs privs that your user probably don't have.

Either you run this stuff as root or you do sth like this:

sudo setcap cap_net_raw,cap_net_admin=eip

on a wrapper script that calls your python interpreter.
