I had been working with Unix and Linux flavors for sometime, and this book has been a blessing for me. I need a book that was willing to detail every aspect of the OpenBSD ( at least the most relevant), kernel, workarounds, etc. And it does its job. Many Thanks,ed

I purchased this book from Amazon on March 4th, 2007. Two months and five days later, after two conversations with Amazon employees who assured me that I would receive the book, they still have not shipped it.

It appears that Amazon simply does not have the book. I phoned the publisher, No Starch Press, and they don't have a copy either. A PDF is available for download, but that's all.

At this writing, the Amazon listing still says that the book "usually" ships in one to two weeks. Amazon is apparently selling a product that it does not have to sell.

If you want this book, you might do better to buy one of the used ones.

I'm no security freak, but I love the OpenBSD concept: security above all. When I took a course in Unix operating systems, I was introduced to OpenBSD, and recommended to purchase this text. Albeit outdated (it covers version 3.2, and OpenBSD is now at 4.0), the book offers an overview of all the basics, including 3 whole chapters on the pf firewall.

Because of its general nature, the author, Lucas, does not solely focus on pf, but instead adds flair to an extremely hostile operating system environment. I don't recall ever working with a more difficult system from scratch. Lucas really helped in getting me through some of the more cryptic areas of installation and configuration. The book itself is quite basic, so if you need something specific, like a korn shell book, look elsewhere. His style also makes the book itself a fun read, I must admit, because of his colorful presentation.

I've had this book for more than a year now.

This may be the most fun textbook-with-no-pictures I've ever read.

Realy I bought the book, I didn't have any OpenBSD contact and I bought the OpenBSD CDs to try it and play, and the book arrived before the OpenBSD's CDs and I begun to read, and learned me how to install OpenBSD, When the CDs arrived realy was very easy to install and get my first steeps in this OS.

So many computer books today are 800 pages of word bloat. Michael not only keeps the writing lively, but in K&R fashion, he gives a lot of information in a succint way. Highly recommended and an easy read. Also note, he gives a complete picture of openbsd from A-Z Not too tedious and not too broad. I have not found a linux book this nice.
