In high-pressure environments, you don’t have time to Google for hours or scroll through outdated forum posts. You need clear, tested solutions—and fast. Fixing Real-World Linux gives you exactly that.
This book is your field manual for diagnosing and fixing production-level Linux problems. Written for sysadmins, ISSOs, and DevOps professionals who need answers in the heat of the moment, it dives deep into the kinds of failures that actually happen in the real world—and how to recover from them.
Author L. Denise Young, a veteran Linux engineer and cybersecurity advisor, shares practical tactics built from years supporting secure and classified environments.

How to troubleshoot disk, memory, and I/O bottlenecks under pressure
What to do when containers, daemons, or services won’t start
Diagnosing firewall, DNS, and SSH access issues quickly
Handling package conflicts, update failures, and missing dependencies

Recovering from permission hardening mistakes and SELinux denials
Case studies that walk through failures step-by-step

Support hybrid or cloud-based Linux systems
Need a playbook for repeatable troubleshooting and RCA (root cause analysis)
Whether you’re fighting filesystem corruption or chasing a ghost in systemd, Fixing Real-World Linux helps you think like a responder—not just a technician.
