Protohacks are a series of network programming challenges. The goal is to write a server for a given protocol and host it on a public IP.

Protohackers challenges you to create servers for network protocols. We give you the protocol spec. You write the server and host it. We automatically test it. There's a global leaderboard for the fastest solve times.

1. Grab your Public IPv6 (recommended) or IPv4 from icanhazip.com
2. If you're behind a NAT, create an ssh tunnel from a VPS to your machine and use the IP of the VPS.
3. Run make to see a list of all the solutions.
4. Run make <solution> to run a specific solution.
5. Go to Protohackers and check your solution.
