• distrib contains all distributable files for all users
• generate contains all relevant source code used to generate the challenge (if not in service directory)
• service contains all the files needed to host the challenge on a server

Setting up challenges for hosting

You may require sudo permissions to run these commands.

Requirements

Challenges that require hosting uses Docker to isolate the challenges.
To install Docker for the common Linux distributions, run the script at: https://get.docker.com/

Setting up a challenge

1. Change your directory to the challenge you would wish to host.
2. Run the build.sh scripts in either the root directory of the challenge or the service directory.
3. Type docker inspect <containername> or enter the docker via docker exec -it <containername> sh and ifconfig to find the IP address and head to that IP.
4. When attempting the challenges in your local setup, do take note to change all *.chal.gryphonctf.com to your local ip
