Project description

Cap: lightweight package for use network captures

PyPI version PyPI downloads GitHub PyPI - Python Version

The idea is to read and write capture files like it is really a serialized data. The API is ment to be close as possible to json and pickle APIs.

Installation:

install the package by:

pip install cap

or from the source:

python setup.py install

Usage:

read cap:

import cap
captured_packets = cap.load(open("C:\\test.cap", "rb"))

filter about somthing

ip_v4_captured_packet = []
for captured_packet in captured_packets:
    if captured_packet.data[12:14] == '\x08\x00':
        ip_v4_captured_packet.append(p)

dump filtered packets

cap.dump(ip_v4_captured_packet, open('C:\\new_test.cap', "wb"))

Have a nice use and please report about problems and issues. Thank you.
