Arp cache poisoning using scapy

[bakbakinfo123]

I am trying to get the arp cache poisoning working with scapy and python but having problems

The python script itself is very simple:
root@ubuntu:/home/joker/Downloads/scapy-2.2.0/scripts# cat arp_poison.py
#!/usr/bin/env python

import sys

from scapy.all import *

arpcachepoison("00:22:fa:98:5e:04", "192.168.1.131")

The error I am getting is illegal IP address. How do I fix it?



root@ubuntu:/home/joker/Downloads/scapy-2.2.0/scripts# python arp_poison.py
WARNING: No route found for IPv6 destination :: (no default route?)

It looks to me like arpcachepoison wants two IP's, not a MAC and an IP.

This works. Although it shouldn't.

The documentation should be changed to reflect this. As per document:

arpcachepoison
arpcachepoison(target,victim,interval=60)
Poison target’s cache with (your MAC,victim’s IP)

It makes more sense to assign a MAC to the vitim ip to falsly claim and poison the network so ideally the documentation is correct the the command does not work as such. However the command with 2 IPs does the thing correctly.. So change documentation? How do one go about it?

Also all the items in () need to have "" or it gives syntax error. Is that how it should work?
