It's not painful but it still requires a few steps. Here I log them.
First thing is to make sure you installed Python 2.x. Not sure about whether Python 3 has similar steps. Also, here I assume Homebrew
is installed too. If any of the following codes result in a Permission denied
error, append sudo
in front the commands.
pip install scapy
pip install git+git://github.com/hellais/pypcap.git
brew install --with-python libdnet
After that, remember to configure the Homebrew's site-packeges so Python recognizes them. Below is an example. Detailed steps can be found above the summary
in the terminal after running brew install ...
mkdir -p ~/Library/Python/2.7/lib/python/site-packages echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth
Now you should be able to use Scapy.
Here is a piece of example code for DNS sniffing using Scapy.
from scapy.all import * interface = 'en0' filter_bpf = 'udp port 53' def dns_sniff(pkt): print pkt.summary() print "start" sniff(iface=interface, filter=filter_bpf, store=0, prn=dns_sniff)
Thank you so much!
Np 🙂
