The Book of PF: A No-Nonsense Guide to the OpenBSD Firewall


The Book of PF: A No-Nonsense Guide to the OpenBSD Firewall Cover


Synopses & Reviews

Publisher Comments:

A solid understanding of OpenBSD's PF subsystem is a necessity for any network administrator working in a BSD environment. PF is the heart of the OpenBSD firewall but there are few quality books and resources for learning PF, which is often a difficult tool to master. This second edition of The Book of PF is an up-to-date, no-nonsense guide to harnessing the power of PF. Author Peter Hansteen covers NAT (network address translation) and redirection, wireless networking, spam fighting, failover provisioning, logging, and more. New additions include coverage of CARP load balancing, and expanded coverage of traffic shaping (including ALTQ queue disciplines such as HFSC), and logging and monitoring. Written for anyone who has felt lost in PF's manual pages or baffled by its massive feature set, The Book of PF, 2nd Edition will help you confidently build the high-performance, secure, low maintenance network you need. (This edition also reflects new developments in OpenBSD, PF, FreeBSD 8.0, and NetBSD 5.)

About the Author

Peter N. M. Hansteen is a consultant, writer and sysadmin based in Bergen, Norway. A longtime Freenix advocate, Hansteen is a frequent lecturer on FreeBSD and OpenBSD topics, an occasional contributor to BSD Magazine and writes a frequently slashdotted blog at http://bsdly.blogspot.com. Hansteen was a participant in the original RFC 1149 implementation team. The Book of PF is an expanded follow up to his very popular online PF tutorial (http://home.nuug.no/~peter/pf/).
