|travis| `Read the Docs `__

This is a simplified object-oriented Python wrapper for libpcap -

the current tcpdump.org version, and the WinPcap port for Windows.

Example use #1::

    >>> 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)))

    ...

Example use #2::

    Listing Interfaces

    >>> import pcap

    >>> print ("Interfaces:\n" + '\n'.join(pcap.findalldevs()))

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.

Installation

------------

This package requires:

* libpcap-dev

* python-dev

To install run::

    pip install pypcap

Installation from sources

~~~~~~~~~~~~~~~~~~~~~~~~~

Please clone the sources and run::

    python setup.py install

Note for Windows users: Please download the `Npcap SDK `_, unpack the archive and put it into the sibling directory as ``wpdpack`` (``setup.py`` will discover it).

Sample procedure in PowerShell::

    cd ..

    wget -usebasicparsing -outfile npcap-sdk-0.1.zip https://nmap.org/npcap/dist/npcap-sdk-0.1.zip

    Expand-Archive -LiteralPath npcap-sdk-0.1.zip

    mv npcap-sdk-0.1\npcap-sdk-0.1 wpdpack

    cd pypcap

    python setup.py install

To regenerate code please use::

    cython pcap.pyx

Building docs

~~~~~~~~~~~~~

To build docs you need the following additional dependencies::
