Packet-Maze

An interactive training tool for budding network programming enthousiast's!

Are you a packet wizard? How's your packet craft? Find out with this interactive trainer!

Start off by doing a little setup (skip if you know what you're doing)

Setup

There are two main dependencies - bcc and Python.

BCC

Find your OS and follow their installation guide - it's fantastic:

• https://github.com/iovisor/bcc/blob/master/INSTALL.md

Once you have bcc setup on your system - run the following on the 'admin' or 'teacher' box.

Python3

If you don't want to run things as sudo - the folloing might work:

sudo setcap CAP_NET_RAW+ep "$(readlink -f `which python3`)"

Otherwise, install the Python requirements and start packet_maze.py

sudo python3 -mpip install -r ./requirements.txt
sudo python3 packet_maze.py --iface eth0

Play

Let students know your IP address and MAC address and have them 'play' the following levels.

Register! : 0 - ARP - Link

Register by sending an ARP reply packet across the link with a source hardware address of FE:ED:ME:13:37:55 to the interfaces broadcast address

Baby Steps... : 1 - IP - Internet

Take the next steps in the wide new world of internet protocol by crafting an evil IP packet, with a payload containing your desired username max length of 10 bytes

Are you Alive? : 2 - ICMP - Internet

Kick off the next stage by sending, as an IPv4 payload, a type 13 ICMP packet with an id value of hex 42, a sequance value of 88 and an Originate timestamp as the IPv4 address 1.3.3.7

Yeet! : 3 - UDP - Transport

Traverse the transport layer by sending an UDP packet from and to port 55555 with a payload of [x)0.0(x]

A Short Conversation. : 4 - TCP - Transport

Traverse the transport layer again by setting up a TCP session on port 55555, with the first data packet containing a payload of ACK\x00\x01\x02\x03 which is PSH'd

World-Wide-Webz : 5 - HTTP - Application

Finish by leveraging a well known application level protocol - HTTP - complete this by sending a HTTP OPTIONS request for all resources using HTTP/13 at the destination port of 55555

Docker

No - it's another layer of silly - you have to expose sys/modules and install the same kernel headers for docker to insert the module anyways - why do that? Open an Issue if you've a great reason.
