python绝技 — 用Scapy解析TTL字段的值

Posted 2020-08-20

 

 

#!/usr/bin/env python
#--*--coding=utf-8--*--
#打印收到的数据包的源IP和TTL值

from scapy.all import *

def testTTL(pkt):
	try:
		if pkt.haslayer(IP):
			ipsrc = pkt.getlayer(IP).src
			ttl = str(pkt.ttl)
			print ‘[+] Pkt FROM: ‘+ipsrc+‘   TTL: ‘+ttl
	except:
		pass

def main():
	sniff(prn=testTTL,store=0)

if __name__ == ‘__main__‘:
	main()
