Example Challenges for CTF-Gameserver setup

This repository will be processed by an ansible script. The directory structure has to be:

chal1
    checker
        challenge.py
        requirements.txt
    vuln ... an ansible role
        tasks
            main.yml
    exploit
        xxx ... put your exploit here for manual testing
chal2
    ...

Testing your checker

You must install the CTF-Gameserver locally:

git clone --branch kdctf https://github.com/KaindorfCTF/ctf-gameserver.git

Now create a virtualenv and install it (assuming you are in the checker directory):

virtualenv -p /usr/bin/python3 ENV
source ./ENV/bin/activate
pip install /path/to/ctf-gameserver/
pip install -r requirements.txt

Now you can test your checker using:

python checker.py <ip> <team-net-no> <tick>

With parameters:

• ip: IP of your target service
• team-net-no: irrelevant (use 1 for instance)
• tick: tick number (use incrementing numbers starting with 0)
