Overview

Absolute OpenBSD: UNIX for the Practical Paranoid by Michael W. Lucas

The definitive guide to OpenBSD

Foreword by Henning Brauer, OpenBSD PF Developer

OpenBSD, the elegant, highly secure Unix-like operating system, is widely used as the basis for critical DNS servers, routers, firewalls, and more. This long-awaited second edition of Absolute OpenBSD maintains author Michael Lucas's trademark straightforward and practical approach that readers have enjoyed for years. You'll learn the intricacies of the platform, the technical details behind certain design decisions, and best practices, with bits of humor sprinkled throughout. This edition has been completely updated for OpenBSD 5.3, including new coverage of OpenBSD's boot system, security features like W^X and ProPolice, and advanced networking techniques.

You'll learn how to:

  • Manage network traffic with VLANs, trunks, IPv6, and the PF packet filter
  • Make software management quick and effective using the ports and packages system
  • Give users only the access they need with groups, sudo, and chroots
  • Configure OpenBSD's secure implementations of SNMP, DHCP, NTP, hardware sensors, and more
  • Customize the installation and upgrade processes for your network and hardware, or build a custom OpenBSD release

Whether you're a new user looking for a complete introduction to OpenBSD or an experienced sysadmin looking for a refresher, Absolute OpenBSD, 2nd Edition will give you everything you need to master the intricacies of the world's most secure operating system.

"The definitive book on OpenBSD gets a long-overdue refresh."

-Theo de Raadt, OpenBSD Founder

Just reading the Absolute OpenBSD book really isn't enough to learn a lot of the aspects of the OpenBSD operating system, but the book definitely gives you a great reference and information to fall back on when learning how to use OpenBSD or learning something new about it. For me it really wasn't the learning the feel of Linux/BSD that gave me some trouble in OpenBSD since being familiar with Slackware Linux helps out for learning the feel, but it was mainly just some of the major differences between them such as PF vs. IPTables for example. This book helped me get past the learning curve of starting the OpenBSD, and in the end the servers of mine running the OS seen an improvement all around in getting things done. I doubt by just reading this book that a user could know OpenBSD inside and out without prior GNU/Linux or BSD familiarization, but the book does a good job at going over the OpenBSD operating system and it's security features/advantages along with going into detail about just about anything pertaining to this extremely secure and locked down operating system, also will allow even veteran OpenBSD users to possibly learn something new. The last great thing about this book is that it's fairly up to date, but did leave one thing out that I would have liked to seen in the book; the CARP system that is new since OpenBSD 3.5. But I guess since CARP just came around since 3.5, it's understandable that it wasn't really covered in this book. All in all I would recommend this book to anybody with GNU/Linux or BSD experience and looking to expand their knowledge into OpenBSD, but for newer users of this type of system I would recommend also seeking more information from the OpenBSD manual pages or have a OpenBSD machine on hand for trying things while you read through the book.
