If you don't know someone who can help you, this book can get you through the tough spots; you just need will.
Putnam
The author has a very straightforward yet humorous writing style, and he neither talks down to the reader nor assumes that you are a SysAdmin and networking god.
David
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.

OpenBSD is lauded for its security features -- this is THE OS to use for serious firewalls or secure web servers and the like. However, it is small and obscure compared to the better known, more popular FreeBSD, and of course there are 10 Linux users for every 1 person who has even heard of OpenBSD.
Until now, installing and using OpenBSD required reading numerous man pages and online FAQs and tutorials. OpenBSD's documentation is pretty good, but for the average person who just wants to try it out, it's an awful lot to wade through, with few navigational aids available. And the OpenBSD mailing lists are notoriously unforgiving of anyone who asks questions without having read every pertinent document first.
"Absolute OpenBSD" is just what this OS needed to make it more accessible to a wider user base. It takes you step by step through installation, configuration, and implementation, and then covers a number of more advanced topics, including no less than three very comprehensive chapters devoted to pf, OpenBSD's own packet filtering program. (OpenBSD uses this instead of ipchains or iptables, which is what you will find on other BSDs or Linux.) It tells you what every service you might want to run (or not) is, and where they are found and how to configure them. It goes through the contents of OpenBSD's /etc directory, file by file.
The author has a very straightforward yet humorous writing style, and he neither talks down to the reader nor assumes that you are a SysAdmin and networking god. He does assume that you have some familiarity with UNIX-style OSs and basic UNIX/Linux commands.

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.

Six months ago I was happy to read Michael Lucas' "Absolute BSD," and today I'm glad I read "Absolute OpenBSD." This author knows just what to cover, and to what detail. To test the book's relevance I bought an OpenBSD 3.3 CD-ROM set and installed it, following Lucas' directions. I tried many of the procedures in the book, and found Lucas' instructions to be accurate on the whole. (Right now I'm rebuilding a system to incorporate a security patch that needs certain static binaries to be recompiled from source.)

Lucas provides the background and skills needed to get a working OpenBSD system. Although some of the most basic UNIX-type material appears by necessity in both "Absolute" books (these are both BSDs!), Lucas knows where each OS' strength lies. In his FreeBSD book, he spends more time on general purpose server services. Web, FTP, email, DNS, etc. all get their own chapters. In this OpenBSD book, Lucas devotes multiple chapters to topics that matter most to OpenBSD users -- security and packet filtering. While lots of people run Web, etc. on OpenBSD platforms, OpenBSD offers unique features in its systrace system call access control and PF packet filtering tools. Beyond these OpenBSD strengths, Lucas gives plenty of coverage to the routine yet crucial system administration tasks of adding and removing applications, and upgrading and patching the OS itself.

On the downside, some have commented on "rough editing." While the book has some typos, I didn't find them all that distracting. Beware p. 344, though -- I think "tag=OPENBSD3_2" should read "tag=OPENBSD_3_2". (This is subtle but could be important.) I also found the description of network layers in ch 8 to be perplexing.

If you want to use the internet with minimal security risks, you want to use OpenBSD -- but there are aren't that many intro materials. Just getting a box set up, so that you can search the web for answers is tough. If you don't know someone who can help you, this book can get you through the tough spots; you just need will.

With this book, you can install the OS and get on the Web securely and quickly. Almost all your problems will not be with OpenBSD itself, but with your complicated DSL modem, ISP or sendmail.

There's very practical information in this book (e.g. IP aliasing -- good if you want hidden machines on your LAN) that isn't in more encyclopedic books. This is one of the best things about this book, the very high signal to noise ratio. If you want a reference for OpenBSD, try the FreeBSD books -- some are excellent, and they are similar enough to OpenBSD that you'll be able to get done what you need to get done. But read and re-read Lucas's book before you try new things.

The author didn't make clear that OpenBSD attempts to prevent failures proactively, even if it means you get cryptic and alarming warnings. Where other OS's silently accept or ignore potentially bad things (e.g. ARP cache poisoning), OpenBSD sounds the alarm. If you've simply misconfigured stuff, these warnings can scare you. Just look on the web for answers; others have made these same mistakes.

More details on how to recover from mistakes would have been nice. E.g. what to do if you suboptimally partition the disk, or what if you get the IP address wrong. You better know something about Unix beforehand. Notes on how to fix major problems (e.g.
