The Complete FreeBSD, 4th Edition
FreeBSD is by far the most popular version of BSD, the legendary operating system that has contributed a great deal to every version of Unix® in use today (including Mac OS X). Originally a community effort by the University of California at Berkeley, FreeBSD was aimed at making Unix a little friendlier and easier to use. By the time other free operating systems came along, BSD was firmly established and very reliable. And it continues to be today.

For seven years, the FreeBSD community has relied on Greg Lehey's classic, The Complete FreeBSD, to guide them through its configuration and administration. more »
The Book of PF, 2nd Edition
OpenBSD's stateful packet filter, PF, is the heart of the OpenBSD firewall and a necessity for any admin working in a BSD environment. With a little effort and this book, you'll gain the insight needed to unlock PF's full potential.

This 2nd edition of The Book of PF has been completely updated and revised. Based on Peter N.M. Hansteen's popular PF website and conference tutorials, this no-nonsense guide covers NAT and redirection, wireless networking, spam fighting, failover provisioning, logging, and more. more »
iOS and OS X Network Programming Cookbook
Darwin, which forms the core set of components for OS X and iOS, is compatible with the Single UNIX Specification Version 3 and POSIX UNIX. Therefore OS X and iOS are UNIX operating systems. While there are numerous books and articles written to teach network development in a UNIX environment there is surprisingly little dedicated to teaching network development specifically in an Apple environment. In this book we will be covering the standard UNIX networking stack with BSD Sockets as well as Apple's frameworks like CFNetworking and Bonjour.

iOS and OS X Network Programming Cookbook is an enthralling code-focused book on developing client and server applications for the iOS and OS X environments. You will learn how to integrate a number of Unix (BSD Sockets), Apple specific (CFNetworking, NSMutableURLRequest, Bonjour) and third party APIs (AFNetworking, MKNetworking) with your own apps. more »
Designing BSD Rootkits
Though rootkits have a fairly negative image, they can be used for both good and evil. Designing BSD Rootkits arms you with the knowledge you need to write offensive rootkits, to defend against malicious ones, and to explore the FreeBSD kernel and operating system in the process.

Organized as a tutorial, Designing BSD Rootkits will teach you the fundamentals of programming and developing rootkits under the FreeBSD operating system. Author Joseph Kong's goal is to make you smarter, not to teach you how to write exploits or launch attacks. You'll learn how to maintain root access long after gaining access to a computer and how to hack FreeBSD.

Kongs liberal use of examples assumes no prior kernel-hacking experience but doesn't water down the information. All code is thoroughly described and analyzed, and each chapter contains at least one real-world application. more »
