Palo Alto Log Cruncher

Introduction

pacrunch.py is a Python application that can "crunch" Palo Alto traffic log files. This script was written for work in a hurry and it is my intention to go over it and fix it in the future, there may be some overlooked bugs. It was a useful script for essentially one niche purpose.

To Do

  • Add more command line arguments.
  • Clean up the code.
  • Figure out more useful features to add.
  • Add support for IPv6 (Hard to do currently as my workplace doesn't support IPv6 yet).

Features

  • Deduplicate rows by specifying a column that should be unique.
  • Remove empty rows.
  • Remove specific columns by their header name.
  • Perform a reverse DNS lookup on IP addresses and add a new column with the results.
  • Override the local host DNS server and specify your own.

This is the first official release and it may have some bugs.
