Linux
Linux is the operating system behind 96% of the world's top one million web servers, every major cloud provider, the entire container ecosystem (Docker, Kubernetes, Podman), most embedded devices, and a growing share of developer desktops. If you work in DevOps, cloud, cybersecurity, backend development, data engineering, or system administration, Linux is not optional — it is the platform.
This is the main Linux hub at Dargslan. You will find every Linux eBook we publish here, organized into nine focused subcategories: Linux Fundamentals (your first commands and the filesystem), Linux Administration (users, services, systemd, logs), Linux Security (SSH hardening, firewalls, SELinux, AppArmor, fail2ban), Linux Networking (the modern ip command, DNS, routing, firewalls, packet capture), Linux Servers (web, database, mail, file servers in production), Linux Storage (LVM, RAID, ZFS, NFS, iSCSI, backup strategies), Linux Certification (Linux Essentials, LPIC-1, LPIC-2, RHCSA, RHCE, CompTIA Linux+), Debian/Ubuntu (the most popular desktop and server distribution), and RHEL/AlmaLinux (the enterprise standard).
Every book in this category is built around the same philosophy: teach Linux the way professionals actually use it — from the command line, with real commands you run on real systems, on multiple distributions so the knowledge transfers. We deliberately avoid the two failure modes that kill most Linux books: the 800-page reference no one finishes, and the toy tutorial that leaves you stranded the moment you face a real production problem. Our books are short, focused, and exam-aligned where it matters.
The recommended starting points depend on your goal. For complete beginners we suggest the Linux Essentials 8-Volume Series followed by Linux Administration. For certification candidates, jump straight to the dedicated LPIC-1, LPIC-2, or RHCSA preparation books. For DevOps and cloud engineers who need Linux production-ready, start with Linux Security and Linux Servers. For SREs and senior administrators, the Linux Storage and Linux Networking deep dives close the most common knowledge gaps.
