Python模拟ICMP包

主要使用Scapy来完成

基础环境

VM1(192.168.1.226)

|

|

VM2(192.168.1.125)

 

vm1封装icmp包发给vm2

vm1脚本:

#! /usr/bin/env python

from scapy.all import *

target = "192.168.1.125"
ip = IP()
icmp = ICMP()
ip.dst = target

icmp.type = 0
icmp.code = 0
send(ip/icmp)

 

vm2脚本

from scapy.all import *

packetCount = 0

def customAction(packet):
    global packetCount
    packetCount += 1
    if len(packet)>0 and len(packet[0])>1:
      if hasattr(packet[0][1],'src') and packet[0][1].src == '192.168.1.226' and packet[0][1].dst=='192.168.1.125':
        print packet.show()
    #return "Packet #%s: %s ==> %s" % (packetCount, packet[0][1].src, packet[0][1].dst)
    return None

sniff(filter="ip",prn=customAction)

  

这样我们就可以使用iptables来添加规则限制icmp的各种type各种code包了
