Product Description
FreeBSD--the powerful, flexible, and free Unix-like operating system--is the preferred server for many enterprises. But it can be even trickier to use than either Unix or Linux, and harder still to master.

Absolute FreeBSD, 2nd Edition is your complete guide to FreeBSD, written by FreeBSD committer Michael W. Lucas. Lucas considers this completely revised and rewritten second edition of his landmark work to be his best work ever; a true product of his love for FreeBSD and the support of the FreeBSD community. Absolute FreeBSD, 2nd Edition covers installation, networking, security, network services, system performance, kernel tweaking, filesystems, SMP, upgrading, crash debugging, and much more, including coverage of how to:

• Use advanced security features like packet filtering, virtual machines, and host-based intrusion detection
• Build custom live FreeBSD CDs and bootable flash
• Manage network services and filesystems
• Use DNS and set up email, IMAP, web, and FTP services for both servers and clients
• Monitor your system with performance-testing and troubleshooting tools
• Run diskless systems
• Manage schedulers, remap shared libraries, and optimize your system for your hardware and your workload
• Build custom network appliances with embedded FreeBSD
• Implement redundant disks, even without special hardware
• Integrate FreeBSD-specific SNMP into your network management system.

Whether you're just getting started with FreeBSD or you've been using it for years, you'll find this book to be the definitive guide to FreeBSD that you've been waiting for.

5.0 out of 5 stars Thank goodness for Michael Lucas and FreeBSD, December 20, 2007

By	Richard Bejtlich "TaoSecurity.com" (Metro Washington, DC) - See all my reviews (TOP 500 REVIEWER)    (REAL NAME)

Almost five years ago I reviewed Absolute BSD, Michael Lucas' first book on FreeBSD. I gave that book five stars, back when several other BSD books provided competition. On the eve of 2008, I am happy to say that Michael Lucas is probably the best system administration author I've read. I am amazed that he can communicate top-notch content with a sense of humor, while not offending the reader or sounding stupid. When was the last time you could physically feel yourself getting smarter while reading a book? If you are a beginning to average FreeBSD user, Absolute FreeBSD 2nd Ed (AF2E) will deliver that sensation in spades. Even more advanced users will find plenty to enjoy.

One of the best aspects of AF2E is that it is modern and covers FreeBSD 7.x. The previous edition covered 4.x, and plenty has changed since then. I've used FreeBSD regularly since 4.1.1 (Aug 2000), and AF2E taught me a lot about my favorite OS. Michael's coverage of GEOM, NanoBSD, FreeSBIE, journaling, memory file systems, filesystems in a file, and other topics really opened my eyes. Michael delivers excellent line-by-line explanations of system output, using numbered references to guide the reader.

Another major reason I love AF2E is that it is a good system administration book that covers plenty of FreeBSD nuances. Michael shares many of his experiences running FreeBSD in production, and I always believe he is teaching the reader what he or she needs to use FreeBSD to support customers. For example, I liked the hint on p 221 about disabling hard drive write caching (hw.ata.wc=0 in /boot/loader.conf). I also liked hearing about netstat -m to see kernel memory used for networking.

The book is also very lively for a system administration title. One of my favorite lines appears on p 135:

"Ethernet has many device-like characteristics, and it's simplest for FreeBSD to treat it as a device. Leave this [kernel option alone], unless you're looking for a learning opportunity."

So far AF2E has received all positive reviews, but I'm sure there's some deficiency another reader will report. In an ideal world I would have read more on FreeBSD binary updates, especially those involving minor releases (say 6.2 to 6.3) and major releases (say 6.2 to 7.0). Those developments are too recent to have appeared in the book, but they appear in 7.0 and will provide exceptional power for many users. I think enough completely FreeBSD-specific chapters (performance tuning, /etc, and others) are present that it's easy to say this is an awesome FreeBSD book.

If you want more coverage of Pf (and found AF2E's material lacking), just buy a copy of the new title The Book of PF: A No-Nonsense Guide to the OpenBSD Firewall by Peter Hansteen. If you want more detail on installing certain applications on FreeBSD, buy Building a Server with FreeBSD 7 by Bryan Hong. Kudos to No Starch for publishing AF2E and these other BSD titles.

5.0 out of 5 stars ABSOLUTELY VERY HIGHLY RECOMMENDED!!, December 14, 2007

By	John R. Vacca "Tech Write Independent Reviewer" (Pomeroy, Ohio) - See all my reviews (REAL NAME)

Are you a new Unix administrator? If you are, then this book is for you. Author Michael W. Lucas, has done an outstanding job of writing a book that will enable you to use FreeBSD to provide network services.

Lucas, begins with a discussion of the information resources the FreeBSD Project and its devotees provide for users. Then, the author gives you an overview of installing FreeBSD and others advice on an optimal install. Next, he shows you how the FreeBSD boot process makes your system start, stop, and reboot in different configurations. The author also discusses how to back up your data on both a system-wide and a file-by-file level, and how to make your changes so that they can be easily undone. He continues by describing how to configure the FreeBSD kernel. Then, the author discusses the network and how it works in FreeBSD. Next, he shows you how to make your computer resist attackers and intruders. The author continues by covering some of the details of working with hard drives in FreeBSD, support for other filesystems, and a few network filesystems. Then, he discusses some of the more interesting security features found in FreeBSD. Next, the author describes the many configuration files in FreeBSD and how they operate. He continues by describing the ports and packages system that FreeBSD uses to manage add-on software. Then, the author discusses some of the finer points of running software on FreeBSD systems. Next, he shows you how to use FreeBSD's upgrade process. The author continues by describing DNS and shows you how to install and troubleshoot it. Then, he discusses some of the small programs you'll need to manage in order to use FreeBSD properly. Next, the author describes how to set up an email system on FreeBSD to reliably deliver mail and repel spam and viruses. He continues by showing you how to setup and secure Web and FTP Services. Then, the author goes over some of the fancy techniques FreeBSD supports for mirroring disks, exporting disk devices across the network, and generally having a good old time protecting and manipulating your data. Next, he covers some of FreeBSD's performance-testing and trouble-shooting tools and shows you how to interpret the results. The author continues by showing you some of the more interesting tricks you can do with FreeBSD, such as running systems without disks and with tiny disks, as well as, some live failover and redundancy setups. Finally, the author wraps up by showing you how to deal with those rare occasions when a FreeBSD system fails, how to debug problems, and how to create a useful problem report.

This most excellent book shows you how to manage, patch, and maintain your FreeBSD systems and have a basic understanding of networking, system security, and software management. In other words, after reading this book, you will be armed with a strong working knowledge of how FreeBSD can be used as a powerful desktop or development machine.

5.0 out of 5 stars Best FreeBSD book out there., November 29, 2007

By	Lisandro Grullon "Lisandro Grullon" (New York, NY) - See all my reviews (REAL NAME)

I have been a freebsd user for a little over 3 years in a real network environment with over 1000+ nodes at my facility. At first the handbook seems like a very complicated compilation of how-to's from different individuals, a class mate ask me to grab a copy of Absolute FreeBSD by Michael W.Lucas. I got online and this book was just coming out, so I decided to give a try, after reading half of the book, I have to say that Michael Lucas is an excellent writer; he describes in a very chronological/concise manner using graphics and commands the necessary steps to install, secure and make a useful system out of FreeBSD. Many of us are waiting for the 7.x release, he also cover the material in that upcoming release or at least part of it.

I am really exited about this book, I will be purchasing the OpenPGP book that Michael Lucas also published, as I said he is a great writer and if you want to learn FreeBSD without going through the nuts and bolds of the handbook this is the best source that will teach you step by step this great Operating System.

If you want to learn FreeBSD from in to out, get this book. Period.
