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."

    Comments about oreilly Absolute OpenBSD, 2nd Edition:

    Michael W. Lucas only writes one kind of book: Incredibly useful, entertaining, and lacking in fluff. This second edition of Absolute OpenBSD is no exception. Virtually all the new features in OpenBSD are well described here, along with overviews of each protocol covered. My only complaint, and it's a small one, is the absence of a example configuration for a pf firewall handling SIP and RSTP traffic. Even so, Lucas provides the conceptual tools to accomplish this and many other things using OpenBSD.

    Get up to speed with OpenBSD

    Comments about oreilly Absolute OpenBSD, 2nd Edition:

    With the ever-increasing variety of cloud-based web application platforms, the likelihood of a developer needing to deploy and administer a full-fledged server or VPS seems to be getting smaller all the time. However, situations still arise when running your own hardware is advantageous for your application. Absolute OpenBSD by Michael W. Lucas is a great way for someone who is a 'geek-but-not-yet-sysadmin' to get acquainted with the ins and outs of administering an OpenBSD installation.

    Lucas's writing is very cogent and informative: Throughout the book I either felt like a) I understood what he was talking about, or b) if my lack of experience kept me from understanding particular section, I knew what man pages or other resources I could utilize to better familiarize myself with a particular concept. I found the chapters on pre-installation planning, disk partitioning, group accounts, and configuring sudo to be especially useful in enhancing my own understanding of how OpenBSD works. The two chapters on PF also helped me wrap my head around OpenBSD's packet filtering system and even include some discussion about bandwidth management (one of reasons I originally wanted to look into PF).

    My objective for reading Absolute OpenBSD was to familiarize myself with the various installation, configuration, and maintenance tasks required to run an OpenBSD system, and for me it has served as a very good resource in this regard.
