Packet Manipulation via Scapy

This repository is lab for NCTU course "Introduction to Computer Networks 2018".

---

Abstract

In this lab we are going to learn how to use Scapy - a powerful interactive packet manipulation program, which can forge or decode packets of a wide number of protocols, send them on wire, capture them, match requests and replies, and much more.

Objectives

This lab aims to learn how we use Scapy and Python to program a simple network protocol and observe the behavior of packet sending and receiving via Wireshark.

1. Basic knowledge of Docker
2. Linux networking
3. Python with Scapy
4. Wireshark
5. Git & GitHub
