In applying the knowledge on the pages below, you may encounter commands not covered here that you'll need information on and how to use.
This isn't the whole site. It's one road through it. Nine stops, each
building on the last. Sysadmin skill isn't the goal here — it's
just what happens if you actually finish the walk.
-
Fundamentals
The commands you'll type without thinking about it, eventually.
-
VI
You'll live in this over SSH. Learn it before you need it in a crisis.
-

-
Filesystem
What you've actually been navigating this whole time.
-
Users-Groups
Who owns what, and who's allowed to touch it.
-
Security
Locking down what you now understand well enough to protect.
-

Disks, volumes, and what happens when one fails.
-
NetworkManager
Getting a box talking to the network it's sitting on.
-
LAMPS
Put it all together and build something that actually runs.
Everything else on the site is still here when you need it — see the
full section index. This is just one way in.
