PcapPy
PcapPy is a Python wrapper for libpcap purely written in Python. That's right! No need to compile anything using ugly wrapper frameworks like Cython, Pyrex or SWIG (yuck!). Using the pure power of ctypes, PcapPy will give you that warm fuzzy feeling at night.
Installation
Simple:
sudo easy_install pcappy
Winning!
Example
Sure why not:
#!/usr/bin/env python
from pcappy import PcapPyOffline, open_offline
from sys import argv
if not argv[1:]:
print 'usage: %s <dump.pcap>' % argv[0]
exit(-1)
# Open the file
p = open_offline(argv[1])
# or this instead: p = PcapPyOffline(argv[1])
# Parse only HTTP traffic
p.filter = 'tcp and port 80'
def gotpacket(d, hdr, data):
print d, hdr, repr(data)
d['count'] += 1
# pass in some random parameters to loop()'s callback. Can be any python object you want!
d = {'label': 'HTTP', 'count': 0}
# Parameters are count, callback, user params
p.loop(-1, gotpacket, d)Now run it:
python example.py dump.pcap
Et Voila! You're off to the races!
