Strangle 0.3.1

Library for comprehending DNS messages using BIND parsing

Summary

Strangle is BIND for Python: a Python library for parsing DNS messages using libbind. Strangle allows you to see DNS messages in two ways:

• Direct access to the libbind parsing functions (C-style)

• A Python object with various meaningful attributes (OO-style)

Demo

Here is an example of how simple it is to parse DNS messages:

>>> import Strangle
>>> msgFile = file("test/data/www.microsoft.com-query")
>>> msg = Strangle.DNSMessage(msgFile)
>>> msg.id
47096
>>> print msg
ID     : 47096
