据说scapy是一个很厉害的东西
使用的scapy版本为2.1.0,注意导入包的方式与原书略有差别
scapy_arping.py
#!/usr/bin/env/python
from scapy.all import srp,Ether,ARP,conf
import sys
def arping(iprange="192.168.137.0/24"):
"""Arping function takes IP Address or Network, returns nested mac/ip list"""
conf.verb=0
ans, unans=srp(Ether(dst="ff:ff:ff:ff:ff:ff")/ARP(pdst=iprange), timeout=2)
collection = []
for snd, rcv in ans:
result = rcv.sprintf(r"%ARP.psrc% %Ether.src%").split()
collection.append(result)
return collection
if __name__ == '__main__':
if len(sys.argv) > 1:
for ip in sys.argv[1:]:
print "arping", ip
print arping(ip)
else:
print arping()
运行结果:
[root@centos python]# python scapy_arping.py
[['192.168.137.1', '00:50:56:c0:00:08']]
注意事项:
在运行过程中可能会有ipv6的warning
WARNING: No route found for IPv6 destination :: (no default route?)
解决方法:修改scapy安装目录下的all.py
注释掉下面几行
#if conf.ipv6_enabled:
# from utils6 import *
# from route6 import *
重新python setup.py install即可
