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

说明与用途

tmpfs.tech 提供真实、隔离的 VM 供学习者进行 Linux 系统管理实践，解决真实问题并获得自动评分。

问题

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

结果

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

工作流

• 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

证据

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.
