PyStack

Pystack, is a python framework that allow to create small TCP/IP stacks in an easy manner in order to obtain a wanted behavior. The applications are multiples and there is currently no any module that provide similar functionnalities in python.

It is developped above the Scapy framework to bring some network stateful functionalities adding to it multiple protocols implementations themselves architectured into a stack which allow the different layers to communicate. All this brings the IP stack in userland and then allow to do anything on network packets like modifying the network stack behavior without patching the Linux kernel.
