What’s Inside the Fourth Edition ⚙️

This edition has been fully updated for Ubuntu 22.04 LTS, bringing new coverage of Snap packages, hardware enablement updates, and the latest tools. You’ll start by planning your server’s role and choosing the right hardware or virtual platform.

You’ll manage users and groups, configure sudo, and set up password policies. You’ll master essential commands, edit files with Nano and Vim, and write backup scripts with rsync. The book also covers process management, systemd, networking, and storage, along with strategies for keeping your server secure and up to date.
