pcap-ct 1.2.3b1

Python wrapper for the pcap library (ctypes/cffi-based pypcap).

pcap-ct

Python wrapper for the pcap library.

Overview

Python pcap-ct package is a simplified object-oriented Python wrapper for libpcap C library - the current tcpdump.org version, and the WinPcap port for Windows..

pcap-ct is a pure Python package, based on the low-level libcap package.

It is fully compliant implementation of the original PyPCAP 1.2.3 API (with some minor improvements and bug fixes) by implementing whole its functionality in a clean Python instead of Cython and C.

About original PyPCAP:

Borrowed from the original website:

PyPCAP

This is a simplified object-oriented Python wrapper for libpcap - the current tcpdump.org version, and the WinPcap port for Windows.

Example use:

>>> import pcap
>>> sniffer = pcap.pcap(name=None, promisc=True, immediate=True, timeout_ms=50)
>>> addr = lambda pkt, offset: '.'.join(str(ord(pkt[i])) for i in range(offset, offset + 4))
>>> for ts, pkt in sniffer:
...     print('%d\tSRC %-16s\tDST %-16s' % (ts, addr(pkt, sniffer.dloff + 12), addr(pkt, sniffer.dloff + 16)))
...

Windows notes

WinPcap has compatibility issues with Windows 10, therefore it’s recommended to use Npcap (Nmap’s packet sniffing library for Windows, based on the WinPcap/Libpcap libraries, but with improved speed, portability, security, and efficiency). Please enable WinPcap API-compatible mode during the library installation.
