Editor’s Note

Dear All,

It is already the fifth issue of BSD magazine and we all hope there will be another 50...and more! I hope you will like

the refreshed layout of the magazine – short news and a little reorganization of the content. Hopefully, you will find it

useful and helpful in your journey to BSD world.

This issue is devoted to FreeBSD distribution. We did our best to cover the most interesting and useful topics in

form of a step-by-step tutorials, so that everybody can take the chance do it.

For beginners we prepared the article describing the process of FreeBSD 7.1 installation and configuration. In

the how-to’s section we covered topics like OpenSMTPD, GNOME desktop on FreeBSD, packaging software, Jabber

server, building wireless router, CPU scaping and much more.

In security corner you will find articles devoted to LDAP authentication and Snort Intrusion Detection Scanner. For

those of you, who are interested in multimedia on BSD systems, Donald T. Hayford wrote a great article on building

an embedded video web server. We also included lots of tips&trick by Dru Lavigne and Mikel King.

As always, we are waiting for your comments, replies, ideas and suggestions. If you would like to become BSD

author or betatester, don’t hesitate- keep the mails coming in!

Enjoy!

CPU Scaling on FreeBSD UNIX

Slawomir Wojciech Wojtczak (vermaden)

Comparing FreeBSD to other sollutions like Solaris or Linux

implementations, that directly follow Intel’s defined C-states

and P-states for CPU, FreeBSD goes a bit further by offering

the end user every possible frequency that the CPU can run

on, this may sound misleading, but things will be simple afte

Installing FreeBSD 7.1 with Enhanced

Security (Jails)

Remko Lodder

This article will guide people that are new to FreeBSD on

installing the software and enhancing it’s security by setting

up FreeBSD jails that will give service to for example an

webserver.

DVD description

LDAP Authentication on OpenBSD Boxes

Nicolas Grenèche

LDAP (Lightweight Directory Access Protocol) is a massively

used protocol to store user’s information. This protocol is

implemented in OpenLDAP, a directory software available on

every operating system’s package manager.

how-to’s

FreeBSD and Snort Intrusion Detection

System

Svetoslav P. Chukov

What is an intrusion detection system? The Intrusion Detection

System shortly called IDS is a software and/or hardware

designed to help you to detect attempts of accessing computer

systems, mainly through a network, such as the Internet.

OpenSMTPD

Gilles Chehade

In this issue I will shamelessly take the opportunity to write

about the smtp server that was imported into the OpenBSD

source tree last November. It isn’t enabled yet, it isn’t even

linked to the build, but it is doing good progress and this

article will describe what it currently does.

Getting a GNOME Desktop on FreeBSD

Jan Stedehouder

‘Why would you want to install GNOME on FreeBSD? It’s a

KDE system!’ This summarizes some remarks I got when

checking out how to install the GNOME desktop environment

on a FreeBSD box.

Build An Embedded Video Web Server

With NetBSD

Donald T. Hayford

While it’s safe to say that the recently developed USB video

driver was built and tested using only a desktop “i386-

compatible” machine, the beauty of NetBSD is that the same

driver will work on any NetBSD-supported hardware. So grab

your favorite embedded processor and let’s try some video.

Packaging Software for OpenBSD – Part 2

Edd Barrett

In the last article in this series, we looked at how to package

a simple piece of open source software for OpenBSD. In

this article we build on what we learned last time and move

onto some more advanced features provided by the ports

system in order to package software with more complex

needs.

tips & tricks

FreeBSD Tips

Dru Lavigne

Whether you’re new to FreeBSD or have been using it for

some time, learning a new trick or two can save you time

and increase your user experience.

A Jabber Data Transfer Component

Eric Schnoebelen

So, you’ve got your Jabber server up and running, the family

using it, and you’re still in contact with your friends on the

„walled garden” networks. You’re having family meetings in

using a conference room, and all the family communications

are secure. What next?

Maintaining System Coniguration Files

Using Subversion

Mikel King

Recently I was asked about maintaining a data center full of

servers. More specifically about maintaining a repository of

the configuration files for all servers in the data center. And

this is what I am going to show you in this article.

Building a FreeBSD Wireless Router

Eric Vintimilla

Why use a FreeBSD machine as a wireless access point?

Don’t most Internet Service Providers give you a free modem/

router? While this may be true most of the time, it is not

always the case. Besides, building your own is easy, and it

gives a great deal of options for both System Administrators

and control freaks alike!
