Services from saarCTF 2020

Prerequisites

To build any of the services, first build the base-image

cd base-image
bash docker-build.sh

Building services

Once the base-image has been built, enter a service directory and use docker-compose, e.g.:

cd saarXiv
docker-compose up --build -d

Running checkers

Every service comes with a checkers directory, which contains a python-script named after the service. Running this script should place a flag in the service and try to retrieve it subsequently. Caveat: Make sure the gamelib is in the PYTHONPATH, e.g.:

PYTHONPATH=../../ python saarxiv.py
