I am a Sys Admin with 7 years UNIX experience (Solaris 2.6-9, DG-UX, SCO Unixware/Openserver, Red Hat Linux4-Ent3, Nokia IPSO) and have started to move into the BSD realm over the last year. I have always had an interest in OpenBSD because of the security first attitude and I started using FreeBSD on several servers last year.

Now I find myself with several sparc64 machines with nothing to do. Looking over my network, I see that I can use a bridge with pf enabled in a couple of places as well as a Load Balancer or two. So in comes OpenBSD.

This book was a pleasure to read and reference while getting the OpenBSD boxen in line. It covers the basics of installing, upgrading, patching, and other Sys Admin tasks. It also has three chapters on pf (the firewall for openbsd) which is a major strength of this os.
It was a great intro and fun read (my wife thinks I am disturbed for reading it at the pool :-), while then turning to the OpenBSD FAQ for more insight.

I have become a rabid fan of OpenBSD and see it having a larger role in future deployments of mine.
If you are new to OpenBSD with some Unix-type background, this is the book you need to get started with little fuss.

If you know anything about Unix/Linux then you will love this book. I have found it hard to put this book down and would recomend it to anyone looking to move/use OpenBSD. This book is written for those who are probably new to BSD OS's and have some Linux/Unix experience. I would say that someone new to the *nix enviroment will learn a great deal from this book as well, but having some background will help greatly. A must read from cover to cover. I even read the Intro and I never do that. Cheers to the author and thank you for all the help. "Newbies please read before you post"

A very good book for users with an intermediate knowledge of UNIX/Linux. Some sections, such as the TCP/IP primer will be redundant for many, but apart from that (and a few grammatical errors;)), a great read.

5.0 out of 5 stars Excellent Contribution Feb. 24 2004
Michael Lucas has provided some of the most useful documentation to the BSD family that's available. From his OnLamp columns to his two No Starch Press BSD books, he's given both new and experienced BSD users some great material.
Absolute OpenBSD follows the tradition. This is not a reprint or rewording of the online OpenBSD documentation available. It's like doing a walk-through of an OpenBSD install and configuration with an experienced sysadmin who speaks plain-talk, makes jokes that aren't corny (well, sometimes at least <g>) and gets to the point.
If you're interested in the OpenBSD world, or have a bit of a history with OpenBSD but want to fill in the gaps, or just further your understanding of this awesome operating system, buy this book.

5.0 out of 5 stars A thorough and comprehensive instructional guide Dec 11 2003
Absolute OpenBSD is a thorough and comprehensive instructional guide by Michael W. Lucas to the most secure operating system in the world, with fewer holes than any version of Linux or Windows, and developed expressly for its correctness, security, and reliability, free for any use or purpose. Individual chapters offer a straightforward guide to installing and configuring Open BSD, implementing its unique security features, building flexible customized firewalls, encrypting filesystems, upgrading painlessly, and much more. Absolute OpenBSD is a very highly recommended and distinctly "user friendly" resource for OpenBSD users everywhere.

By Doug M
Before reading this book, I had tried out OpenBSD a little, but I was left with many questions, and online documentation can be a bit intimidating at times. So when I found this book at the bookstore, I was thrilled. I am happy to say that this book really did live up to expectation.
The intended audience of this book were people who knew there way around Unix and Linux. One need not be a veteran user, but as the author points out, you are expected to know basic command line stuff. If you are there, you will find this book to be a very easy going, yet thorough introduction to OpenBSD.
This book walks you all the way through the origins of BSD, through installation (an excellent section of the book), to usage, compiling kernels, and so on. You get a well-rounded coverage of a very interesting operating system.
I also really like the author's style of writing. On the one hand, you get a genuine sense of professionalism, but on the other hand, he cracks some good jokes throughout. If you are a system admin of any sort, you will certainly appreciate the humor.
In closing, I would definitely recommend this book to anyone who's had some experience with Unix and Linux. OpenBSD is a operating system few have tried, but I think after reading this book, you will definitely want to go out and try it yourself. The book is definitely time and money well spent.
