Practice labs
- Five quick tasks: files, users, a service: In fifteen minutes you complete an archive, a user, a group permission, a service enable and a cron line task.
- Five quick tasks: networking and storage: In twenty minutes you do and verify static address, persistent route, logical volume, swap file and NFS mount tasks.
- Five mixed tasks, all reboot-proof: In twenty-five minutes you do RAID, reverse proxy, firewall, timer and resource-limit tasks, reboot and prove they all persisted.
- Set up key-based hops between two machines: You set up passwordless SSH between the two mock servers and confirm by hostname that each task lands on the right machine.
- Export on one machine, mount on the other: You export a share on the first server, mount it persistently on the second, reboot both and verify access.
- Proxy on one machine, back end on the other: You start the back end on the second server, configure the reverse proxy and firewall on the first and show access works only through the proxy.
- Find the option from the man page alone: Without internet you find the required option for three commands with man and --help and run them.
- Find a tool you can't name using local help: Using only apropos and /usr/share/doc you find the tool for the job and derive a working setting from an example configuration.
- Configure an unfamiliar service from its docs: You get a service you've never seen running with the required settings using only its man page and example files and verify it.
- Order tasks by points and time: You order a ten-task list by estimated time and weight and write the five you would do first, with reasons.
- Drop a stuck task and come back: Across six tasks, one deliberately long, you drop the stuck one within five minutes, finish the others and return at the end.
- Verify every task before finishing: You test eight seemingly finished tasks one by one with verification commands and find and fix the two that break on reboot.
