Absolute OpenBSD, 2nd Edition

The best-selling standard work on OpenBSD, fully revised and expanded!

OpenBSD is the world’s most secure networked operating system, in wide use by Internet Service Providers, corporations, and embedded systems manufacturers. The original Absolute OpenBSD was the go-to work on this operating system, earning praise for a decade after its release.

The first copy of Absolute OpenBSD off the press was auctioned off to support the OpenBSD Foundation.

coverThis new edition is fully rewritten and contains the latest details about key OpenBSD features such as the PF packet filter, network VLANs and trunks, packaged software, building your own releases, diskless installs, and more, more, more.

Absolute OpenBSD goes into depth on the features that set OpenBSD apart from the crowd of free UNIX-like operating systems. It reaches beyond explaining what to type, and instead takes the reader into why things work that way.

    Praise for the First Edition:

    This is an excellent book for users and system administrators who want to migrate to the OpenBSD operating system.” ACM Computing Reviews

    “[This] is a well-written book that hits its market squarely on target. Those new to OpenBSD will appreciate the comprehensive approach that takes them from concept to functional execution. Existing and advanced users will benefit from the discussion of OpenBSD- specific topics such as the security features and pf administration.” –Slashdot

    “My current favorite is Absolute OpenBSD: Unix for the Practical Paranoid by Michael W. Lucas from No Starch Press. Anyone should be able to read this book, download OpenBSD, and get it running as quickly as possible.” — Infoworld, December 29, 2006

    “I recommend Absolute OpenBSD to all programmers and administrators working with the OpenBSD operating system (OS), or considering it.”Dr. Dobbs

    ‘Six months ago I was happy to read Michael Lucas’ “Absolute BSD,” and today I’m glad I read “Absolute OpenBSD.” This author knows just what to cover, and to what detail.’ –TaoSecurity
