What is Pcapy?
Pcapy is a Python extension module that interfaces with the libpcap packet capture library. Pcapy enables python scripts to capture packets on the network. Pcapy is highly effective when used in conjunction with a packet-handling package such as Impacket, which is a collection of Python classes for constructing and dissecting network packets.

Compiling the source and installing
As this extension is written in C++ it needs to be compiled for the host system before it can be accessed from Python. In order to compile and install the source, execute
from the directory where Pcapy's distribution has been unpacked. This will install the extension into the default Python modules path (you might need special permissions to write there). For more information on what commands and options are available from setup.py, run:
python setup.py install
python setup.py --help-commands
This extension has been tested on Linux and Windows 2000 and XP systems and is known to work there. However, it should work on any box where Python and libpcap are available.
