- The Book of PF, 2nd Edition
A No-Nonsense Guide to the OpenBSD Firewall
- by Peter N. M. Hansteen
- ISBN-13: 978-1-59327-274-6
- November 2010.
The first sentence of this book is, "This is a book about building the
network you need". Taking it from there, Peter walks you through the whys
and the hows of building the high performance, low maintenance network you need,
using OpenBSD tools.
The book covers all bases from the basic one machine configuration and basic
local area networks, all the way up to configurations with traffic shaping and
load balancing with "self healing" networks and countermeasures against common
problems such as DoS attempts and spamming. A basic understanding of TCP/IP
and some Unix knowledge is assumed.

The Design and Implementation of the 4.4 BSD Operating System
- by Marshal Kirk McKusick, Keith Bostic, Michael J. Karels, John S. Quarterman
At 549 pages plus an index, this book must be considered comprehensive.
McKusick, Bostic and Karels are well known as prime movers at
Berkeley CSRG (Computer Systems Research Group) during the 4.3/4.4BSD
period. This book covers the 4.4 and 4.4-Lite releases, and discusses
everything you wanted to know about how the system operates. Not
100% applicable, but probably the closest there is to an overall
system internals manual for OpenBSD.
Source Code Secrets: The Basic 386BSD Operating System Reference
(Volume 1 of Operating System Source Code Secrets)
- by L. W. Jolitz, William Jolitz; 1997
The Jolitzes built the first port of BSD to the PC-386 architecture,
and deserve a lot of credit for making BSD portable to this low-cost
architecture. The earliest versions, called "386bsd", were described
in articles in Dr. Dobbs Journal. This book goes beyond the articles,
and provides a comprehensive annotated collection of source code.
Not all of it applies to modern versions of OpenBSD, of course, but
you can still learn a lot from it.

Begins with the basic commands and finishes with advanced programming
techniques. Offers strong coverage of systems calls.
An Introduction to Berkeley Unix and ANSI C

for self-study, requires no previous knowledge of Unix. Covers the fundamentals
of programming; the correct use of syntax; programming style, debugging, logic,
and system programming with C.
4.4 BSD User's Reference Manual (URM)
- published by O'Reilly, 1994
This is just a reprint of the man pages for users.
Your OpenBSD distribution includes the online man pages,
which are specific to OpenBSD, and more up-to-date. So
you don't need this one: use the man command instead.
4.4 BSD System Manager's Manual (SMM)
- published by O'Reilly, 1994
This book details what you need to know to run a BSD system.
Quite a bit of this material is relevant to OpenBSD.
Unfortunately it is currently out of print.
Worse, due to licensing restrictions from AT&T,
the electronic editions of these were not included in the
They are not included with OpenBSD.
BSD mit Methode
- published by C&L Computer- und Literaturverlag GmbH, 1998

three freenix BSDs covering the essentials of installation, X configuration
and system administration, as well as PERL programming and tips on
LaTeX/Lyx. The book also covers the KDE desktop environment.
Includes older versions of OpenBSD on the two included CD-ROMs.
Lehmann's Online Bookshop. However, you might want to pick up a more
recent version of the CD-ROM.
The OpenBSD PF Packet Filter Book

- Unix Made Easy
- by John Muster
- A general Unix book that covers all areas of the system.
- UNIX Power Tools
- by Jerry D. Peek, Tim O'Reilly, and Mike Loukides
This book is now in its third edition. It discusses
hundreds of neat tricks, little-known techniques, and add-on utilities.
Be aware that many of the utilities are either included with OpenBSD
or, more commonly, are already available as ports or packages.
So most of section 52.03, complaining about how hard it is to port
software to different UNIXes, can be disregarded if you learn about the
that is part of OpenBSD.

- by Rod Smith
Book explaining techniques for Multi-booting.
- UNIX System Administration Handbook
- by Evi Nemeth, Garth Snyder, Scott Seebass, Trent R. Hein

- Lions' Commentary on UNIX 6th Edition with Source Code
- by John Lions
Although the UNIX described in this book is to BSD as a Model T Ford
is to a 70's Mustang or Thunderbird, UNIX inventor Ken Thompson
claims that "After 20 years, this is still the best exposition
of the workings of a 'real' operating system." Originally circulated
in illicit photocopies, this is the book that most first- and second-generation
UNIX hackers cut their code-teeth on. Recommended as a good introduction
to how a timesharing OS works, if you've not been inside one before.
Substantially shorter than the McKusick book above.
- The Practice of Programming
- by Brian W. Kernighan and Rob Pike
Brian Kernighan had a hand in two other books which we recommend even though they're not UNIX specific, but are useful to programmers on UNIX and elsewhere.
This book covers practical programming considerations for C, C++ and Java.

This book is similar to The Practice of Programming, but older. The

- by W. Richard Stevens, Stephen A. Rago
This is a very detailed and easy to read book. It has several examples
that you can learn from. There is plenty of information about library and
system calls, and associated information so that you can use them.
This book along with the OpenBSD manual pages
make an excellent combination.
- The C Programming Language
- by Brian W. Kernighan and Dennis M. Ritchie
This is a clear and concise guide to the C programming language,
perhaps the only one you will ever need. It focuses strictly on the C language,
not how to use your compiler or anything else.
- C: A Reference Manual
- by Samuel P. Harbison and Guy L. Steele
If you only had two books on C, then along with The C Programming Language, this would be your second one!
This book is not a tutorial (hence the title), it deals with syntax, data types,
ISO C library functions, and C/C++ compatibility.
- The Art of Software Security Assessment

documents) as well as using OpenSSH as an end user.
Although using Linux as a reference OS, many of the examples also have
a description how to get things done under BSD.
In a separate cookbook chapter, several scenarios from daily work are solved
Furthermore, this book is the first German book to cover VPN via OpenSSH.
- SSH, The Secure Shell.
- by Daniel J. Barrett and Richard Silverman
- The Definitive Guide. OpenSSH is covered in detail.
- TCP/IP Illustrated, Volume 1

is an encyclopedia of the TCP/IP protocol suite. This book provides information,
and diagrams useful to understand the suite to its lowest level.
Home enthusiasts, developers, and network administrators alike will enjoy this

industry, in the public sector, and by individuals for their personal
privacy, such as in electronic mail. This Handbook will serve as a
valuable reference for the novice as well as for the expert who
needs a wider scope of coverage within the area of cryptography.
It is a necessary and timely guide for professionals who practice
the art of cryptography.
