The Book of PF

Request Review copy

San Francisco, CA (September 26, 2014) — Network administrators have secured their networks with OpenBSD's PF for more than a decade. But the world of the Internet is changing, and that means PF and OpenBSD need to change too.

In the third edition of The Book of PF (No Starch Press, Oct 2014, 248 pp., $34.95), author Peter N.M. Hansteen returns with more of the life-saving PF and BSD help that made the first two editions such a hit. With the help of this fast-paced, clear, instructional guide, readers will master the latest PF developments to build strong and secure networks better able to handle today's network demands.

The Book of PF gives readers just what they need to know to use PF with the latest versions of OpenBSD, FreeBSD, and NetBSD. Hansteen walks through the crucial steps for basic and advanced setups, from getting started with PF to basic packet filtering, handling services for small and large networks, fighting attackers, logging, monitoring, and more. With IP version 6 a growing reality and OpenBSD replacing ALTQ with a new traffic-shaping system, skillful handling of the new, dramatically different PF is essential to admin success—and The Book of PF is that essential guide.

The Book of PF arrives in fine bookstores everywhere this October.
