고장실습소: Fix the Broken Thing at the Console
A free Korean-language network and infrastructure troubleshooting lab for practicing failures in networks, firewalls, Linux servers, and cloud environments.
Field notes
Scenarios begin with a customer request and expose a simulated topology, device console, and live log stream rather than a passive lesson. The interface supports IOS-style network commands, Linux diagnostics such as journalctl, and AWS-like cloud operations; it also offers a “모르겠어요” option that reveals an answer and its reasoning. The page identifies the CLI as an educational simulation, not a Cisco product, and says the service has no login, ads, or subscription.
