Submit a challenge idea

Got a real Linux task that would make a good hands-on challenge? Pitch it below — pick a category (or suggest a new one), set a difficulty, and describe the scenario. We review every submission.

Challenge title *

A short, action-oriented name — e.g. “Fix the broken nginx config”.

Category *

Which track does it fit best?

Difficulty (optional)

How hard should it be?

New category name *

What should we call this new track?

Describe the challenge * 0 / 4000

What's the scenario and what should the player accomplish? The more concrete, the better — what state the box starts in, what's broken, and the goal.

How would we know it's solved? (optional) 0 / 4000

A concrete success check helps us auto-grade it — e.g. a file exists with given contents, a service is active, a command returns something.

Your name (optional)

So we can credit you if we add it.

Email (optional)

Only if you'd like us to follow up.

✅

Thanks — got it!

Your challenge idea is in our review queue. If it's a good fit you may see it land in the catalog. 🙌
