This book is a guide to FreeBSD for network administrators; therefore it does not cover basic installation and configuration of FreeBSD, but is about using FreeBSD to build, secure, and maintain networks. After introducing the basic tools for monitoring the performance and security of the system the book moves on to cover using jails-FreeBSD virtual environments-to secure your network. Then it shows how to overcome the different bottlenecks that you may meet depending on the services you are running by tweaking different parameters to maintain a high performance from your FreeBSD server. Next it covers using the ifconfig utility to configure interfaces with different layer protocols and about connectivity testing and debugging tools. After covering using User PPP or Kernel PPP for Point-to-Point Protocol network configuration it explains basic IP forwarding in FreeBSD and the use of the built-in routing daemons, routed and route6d, which support RIPv1, RIPv2, RIPng, and RDISC. Next it covers the OpenOSPFD and OpenBGPD daemons that you can install to run OSPF and BGP on your host. Then it covers setup and configuration of IPFW and PF, and finally looks at some important internet services and how to set them up on your FreeBSD server

NAWF7 shines when it addresses items seldom seen elsewhere. For example, I liked reading about adding and encrypting swap space. The book also covered modern topics like Csup, Portsnap, FreeBSD Update, and other recent additions to the FreeBSD OS. I was disappointed to see only a small mention of Portmaster, however. I liked the tables on pp 102-4 explaining flags seen in ifconfig output, e.g., "SIMPLEX Indicates that the interface cannot hear its own transmissions".
I would like to see more or new coverage of the following in a second edition: 1) system performance monitoring and tuning; 2) advanced networking using Netgraph; 3) more IPv6; 4) creating, modifying, and maintaining FreeBSD ports; 5) large-scale system administration, particularly keeping multiple systems configured and updated appropriately; 6) advanced port and package management, especially maintaining a personal package repository; 7) debugging problems with CURRENT and other in-depth subjects. Topics like these would clearly differentiate NAWF7 from other FreeBSD books.
On a final note, I noticed that FreeBSD's current "Fast IPSEC" implementation doesn't use "options IPSEC-ESP" in 7.0. That is a pre-7.0 convention. I also found the author's language distracting. A real copyeditor should have proofed the book and worked out the English language issues.
Farrokhi clearly knows what he is talking about, there were a number of things I learned from the book. However his native language is not English, and I have to wonder if it was even reviewed by a native English speaking editor. I don't fault the author at all for this, I know how difficult writing a book is and couldn't imagine writing one in anything other than English. Packt dropped the ball here with a complete lack of editing. I started making notes on formatting and grammatical issues but gave up less than 50 pages in as the list grew so quickly it felt like work. Some just made the book harder to read, but several left me wondering what exactly he means.
I think there is a place for a good niche book on more advanced network and system administration topics, and many of the topics covered in this book are suitable. I feel like it doesn't go into enough depth in several areas - there were a number of parts where I felt you were left hanging without adequate explanation. For the second edition, I agree with Bejtlich, focus on those areas he listed and get a native English speaker to copyedit and this could be a five star addition to the lineup of FreeBSD books available.
As for this book, it's definitely not something I would recommend to anyone just getting started with FreeBSD - that isn't its intended audience. I feel more seasoned administrators who frequently work with FreeBSD will find enough value in the content to justify the purchase price. Just don't be prepared for a smooth, easy read.
I certainly hope the author and publisher decide to update this book. It is truly a great reference in learning such a massive system such as FreeBSD.
