Hosting

This challenge should be a Docker container that runs the Python script leet2.py every time someone connects on port 40001. All the proper files are included in here. The command to build the docker container is (when located inside of this directory):

sudo docker build -t leet2 .
sudo docker network create -d bridge leet2

The command to start the challenge is:

sudo docker run -p 40001:40000 --detach --name leet2 --network leet2 leet2:latest

The command to stop the challenge (since CTRL+C won't work) is:

sudo docker stop leet2
