Practical info:
  - The real server is in the docker container. This container is to be considered as a distant machine without any physical access possible (popping a shell, dumping the memory or debugging the server in the container are prohibited). *Ideally*, the container logs should not be observed as well.

  - The 'private' directory should never be entered as it contains the necessary files for the server to run and could spoil the challenge.

  - 3 flags in the format "ASF{XXXX}" can be found and retreived from the container server.

  - Simply execute 'run_chall.sh' without any argument to start the container, server and the challenge as a whole.
