Question

Iam尝试在https://null-byte.wonderhowto.com/how-to/build-arp-scanner-using-scapy-and-python-0162731/

之后在Mac OS上执行ARP

继承我的代码（或他的）

import sys
from datetime import datetime
from scapy.all import srp,Ether,ARP,conf
conf.verb = 0
ans, unans = srp(Ether(dst="ff:ff:ff:ff:ff:ff")/ARP(pdst = '192.168.1.0/24'), timeout = 2, iface = 'en0', inter = 0.1)


for snd, rcv in ans:
    print rcv.sprintf(r"%Ether.src% - %ARP.psrc%")

我在Mac OS上运行，它给了我错误：

Traceback (most recent call last):
  File "arp.py", line 5, in <module>
    ans, unans = srp(Ether(dst="ff:ff:ff:ff:ff:ff")/ARP(pdst = '192.168.1.1/24'), timeout = 2, iface = 'en0', inter = 0.1)
  File "/Library/Python/2.7/site-packages/scapy/sendrecv.py", line 378, in srp
    a,b=sndrcv(s ,x,*args,**kargs)
  File "/Library/Python/2.7/site-packages/scapy/sendrecv.py", line 133, in sndrcv
    r = pks.nonblock_recv()
  File "/Library/Python/2.7/site-packages/scapy/arch/pcapdnet.py", line 672, in nonblock_recv
    p = self.recv(MTU)
  File "/Library/Python/2.7/site-packages/scapy/arch/pcapdnet.py", line 653, in recv
    pkt = self.ins.next()
  File "/Library/Python/2.7/site-packages/scapy/arch/pcapdnet.py", line 390, in next
    s,us = h.getts()
AttributeError: 'NoneType' object has no attribute 'getts'

我的ifconfig输出是：

我很确定在同一网络中连接的设备的IP为192.168.1.141，但为什么它找不到它？任何帮助将不胜感激

尝试运行命令sudo pip install pypcap以使错误消失。有关详细信息，请参阅this GitHub Issue。

Mac OS上的Scapy ARP设置为en0不起作用
