Hands‑on Linux challenges on a real throwaway VM, not a quiz

Description and use

tmpfs.tech offers real, isolated VMs for hands‑on Linux administration practice, letting users solve authentic problems and receive automatic grading.

Problem

Linux tutorials often explain commands but never give real broken systems to fix. Users lack hands‑on experience with authentic troubleshooting scenarios.

Outcome

The platform provides authentic, isolated, and automatically graded Linux challenges, enabling users to practice real troubleshooting without affecting their own machines.

Workflow

• 1. Visit https://tmpfs.tech
• 2. Select a challenge from the catalog
• 3. Receive an in‑browser terminal or SSH access to a fresh VM
• 4. Perform the required troubleshooting or configuration tasks
• 5. Submit the solution
• 6. Receive automatic grading based on the VM’s final state

Evidence

Pick a challenge → you get a real Linux session in an in-browser terminal (or SSH). The task is a genuine scenario, not a quiz: repair broken nginx, write an nftables ruleset, debug a failing systemd unit, fix a storage mount, eradicate cron-based persistence after a breach.
