ProtocolStack

ProtocolStack

This repository is for learning network programming in Go and mainly aims to implement TCP/IP stack.

Requirements

• OS: Linux
• Go: 1.14.x or higher

Instructions

ProtocolStack needs a TAP device for its capability. For the reason, this project uses a virtual machine (Linux) to run the application.

1. Preparing for using the virtual machine

Software required is as follows:

• Mutagen
• Vagrant
• VirtualBox

Note: Mutagen synchronizes files between local system and virtual machine.

2. Controlling the virtual machine

vm.sh controls the virtual machine. The available commands are as follows:

• start
• stop
• restart

You can perform the commands below:

> ./vm.sh start   # Start the VM and create a Mutagen session.
> ./vm.sh stop    # Stop the VM and terminate the Mutagen session.
> ./vm.sh restart # Restart the VM and recreate the Mutagen session.

Note: Remote debugging with GoLand

• See the instruction for more detail.

  • Compile and run Go code using WSL 2 and GoLand

3. Compile

It is able to compile the application with make:

> make compile

4. Running application

Start as echo server

./bin/pstack server

Start as client

./bin/pstack ping -c 192.0.2.1

Note: make supports the commands below:

• build build project
• clean clean up caches
• compile resolve dependencies, and build the program
• fmt run formatter
• gen generate source code
• lint run linters (golangci-lint)
• resolve resolve dependencies
• test run all tests

Supported Protocols

• Ethernet
• ARP
  • Request
  • Reply
• IP
  • v4
  • v6
• ICMP
  • Echo Request
  • Echo Reply
• TCP
• UDP

Examples

• ICMP Echo Reply
