Learn › Linux Foundations › Navigation
A real Linux machine, no test attached. It is the exact same outpost the Navigation lab runs on: recon-base and all, with ls, cd, tree and Tab completion ready.
Use it to wander, to rehearse before the module test, or to try the thing you were afraid to try during one. The machine is wiped and rebuilt on every launch, so nothing you do here can go wrong in any way that matters.
Connect in the browser or over SSH, exactly like a lab. The task ticker will still light up if you happen to do lab tasks. It is keeping score of nothing.
Practice The Open Outpost (playground) in a real Linux terminal at The Linux Camp. Progress is verified automatically as you type commands on the machine.
