Packet Wizardry - Ruling the Network with Python

In this tutorial I will cover techniques involving packet construction and manipulation to master the network from the Python command line. No prior knowledge of Python is required, however I guess that when you're as excited about this as I am, you will want to start learning it right away. However, prior knowledge of common network attacks is recommended.

In this tutorial you will get a practical jumpstart into hacking in the network area. The lack of alot of practical information on hacking at the network level makes me guess many hackers have little knowledge about the subject. Maybe you know the basics of TCP/IP and know how to use Nmap.
Maybe you can even do some tricks such as Idle scanning using Hping2. But what exactly have you coded using Libnet? Ever coded a basic sniffer using Libpcap?

Anyway, regardless of your knowledge in the area of network attacks and reconnaissance, this guide would be very interesting.
