在Mac上安装Scapy：“ImportError：没有名为pcapy的模块”

Question

I'm trying to run a python script that involves scapy but I can't seem to get it to run. I keep getting this error

ImportError: No module named pcapy

The script I'm trying to run is:

from scapy.all import *

def arp_display(pkt):
  if pkt[ARP].op == 1: #who-has (request)
    if pkt[ARP].psrc == '0.0.0.0': # ARP Probe
      print "ARP Probe from: " + pkt[ARP].hwsrc

print sniff(prn=arp_display, filter="arp", store=0, count=10)

I've installed XCode, XQuartz, Python, and Scapy using macports

Please let me know what I'm missing! #noob

Answer 1

I had the same problem. I solved this using following steps:

1.) Open terminal and enter the command

sudo pip install --user pcapy

2.) Enter

python

in your terminal

3.) Enter the command

import pcapy

This should fix your problem.

Try installing libpcap and its Python wrapper from source, as listed here , though the latest version is 0.6.4 and not 0.6.2:

$ wget http://dfn.dl.sourceforge.net/sourceforge/pylibpcap/pylibpcap-0.6.4.tar.gz
$ tar xfz pylibpcap-0.6.4.tar.gz
$ cd pylibpcap-0.6.4
$ sudo python setup.py install

Download the latest version of pcapy from this link https://www.coresecurity.com/corelabs-research/open-source-tools/pcapy

Unpack it and from the directory run the following command:

python setup.py install
