scapyHunt - A series of Network Security puzzles and challenges designed to educate users on packet manipulation and common network attacks.

Creates a TUN/TAP interface for a software defined network, over which packets will be sent by the user- either hand crafted or using a variety of tools- in order to achieve a given objective.

Uses scapy, a Python packet manipulation library.
