KNZLABS :: Hands-On Labs

How to Use the Labs

1. In the Lab Operations panel below, click Snapshot Baseline once to capture the clean starting state, then Push Labs to Nodes to distribute the task sheets and graders to ~/labs/ on each lab node.
2. SSH from your laptop to the node for the lab you're working: ssh knzadmin@192.168.4.71 (key auth, no password). The node for each lab is noted on its card in the Graded Labs section.
3. Read the task sheet — click Read tasks → on the lab's card in the Graded Labs section below.
4. Work the tasks on the node. Reboot when the task list says so.
5. Grade your work — open the Lab Grader tile in the Graded Labs section below, then click the grader for the lab you completed. The pass/fail report appears in the Lab Operations console.
6. Between drills, click Reset All Nodes (or a per-node reset) in the Lab Operations panel below to roll back to your clean baseline.

Lab Operations

Buttons below execute against the lab infrastructure from this portal. The portal SSHs to ATLAS through a restricted action whitelist — you don't need a terminal open. SSH from your laptop into the lab nodes still works the same way (it's separate).

Lab Hosts

Graded Labs

Each lab targets one RHCSA v9 objective domain. Work the tasks on the live lab host, reboot when the task list says so, then run the grader. Red Hat's passing score is 70%.
