Deploy¶

Deployment configuration for the "heap3" challenge. Uses xinetd inside a Docker container to serve the challenge over TCP.

Prerequisites¶

Ensure ../publish/ contains chall, libc.so.6, and ld-linux-x86-64.so.2 (see ../build/README.md and ../publish/README.md), and that ../flag exists (the flag file for this challenge).

Building the image¶

The build context must be the parent directory (..), so files from publish/, deploy/, and the flag file can all be copied in:

docker build -t heap3-deploy -f Dockerfile ..

Running the container¶

docker run -d --rm -p 31013:31337 --name heap3-container heap3-deploy

The challenge is now reachable at localhost:31013:

nc localhost 31013

Stopping the container¶

docker stop heap3-container
