About Fragscapy

This project is a command-line tool that can be used to generate ‘fragroute-like’ tests using Scapy.
Fragroute‘s goal was to intercept network packets and modify them “on-the-fly” according to the configuration defined in a config file. So automating tests of different modifications, requires to kill Fragroute, write a new config file and restart Fragroute over and over.
