MaheshaBSD Server Edition Has Been Just Released!
Juraj Sipos
Many newcomers to FreeBSD find it difficult to setup their own FTP/WWW server quickly and, on the other hand, experienced users sometimes need to take precautions for unexpected crash situations – that is, to have a strategy for time economization and portability, as these two are valuable assets in our rushing world. From this article you will find out ow to run a simple and smart FTP/WWW server.

Tuning ZFS on FreeBSD
Martin Matuska
ZFS is a modern 128-bit file system based on the copy-on-write model. It originates from the OpenSolaris project and has first appeared in FreeBSD in 2008. ZFS has many innovative features including an integrated volume manager with mirroring and RAID capabilities, data checksumming and compression, writable snapshots that can be transferred between systems and many more. In this article the author is going to discuss several tuning options including sysctl(2) knobs and give examples how can ZFS performance and efficiency can be measured and evaluated. This article is intended for FreeBSD users with ZFS version 28 available since 8.3-RELEASE and 9.0-RELEASE.

MPD5 – VPN Server with FreeBSD Setup and Management
Antonio Francesco Gentile
Mpd5 is a fast, flexible and secure way to make VPN connections on FreeBSD. It requires very few resources and supports a wide range of protocols, a great tool for network managers. By reading this article you will learn to setup and manage a VPN server PPTP based.

PostgreSQL Partitioning
Luca Ferrari
In the previous articles the main features of PostgreSQL, including server-side programming were shown. In this article a simple application scenario will be used to demonstrate the capability of partitioning huge amounts of data into different tables in different spaces transparently.

DNSSEC Part 4: Securing DNS Transactions
Paul Ammann
In the June 2012 issue, we outlined the threats, security objectives, and protection approaches for various DNS transactions. This article provides the steps involved in implementing those approaches, as well as operational best practices that go with those implementations.

Deploy a Full-featured Mail Server on OpenBSD 5.1 with iRedMail
Zhang Huangbin
iRedMail installs and configures mail server binary packages automatically from the official software repositories provided by Linux/BSD distribution venders. These packages include: Postfix, Dovecot, Apache, OpenLDAP, MySQL or PostgreSQL, Amavisd and Roundcube. The article is dedicated to Open Source edition of the program.

freebsd-update as Intrusion Detection System
Michael W. Lucas
One of the most annoying things a sysadmin can endure is a system intrusion. A script kiddie might only install an IRC bot, but a skilled intruder can carefully replace core system binaries so as to exploit more systems or extract more data. An Advanced Persistent Threat (APT) intruder might even patch and secure a penetrated system, so as to delay detection…

Taming the Blowfish with a Dog
Antoine Jacoutot
This article is meant to be a quick, yet comprehensive overview of using Kerberos to manage user passwords and single-sign-on on OpenBSD. It is by no way an exhaustive documentation about Kerberos – entire books have been written about it!

Upgrading Ports Using Portmaster
Edward Tan
On a FreeBSD server, the system administrator has the choice of using either packages (binary) or the ports system (source). Packages are precompiled binaries from the source in the ports system. These packages come with some sane default options. It is sufficient for a server with minimum customization.

Hardening FreeBSD with TrustedBSD and Mandatory Access Controls (MAC) Part 2
Michael Shirk
Most system administrators understand the need to lock down permissions for files and applications. In addition to these configuration options on FreeBSD, there are features provided by TrustedBSD that add additional layers of specific security controls to fine tune the operating system for multilevel securit.y From this article you will learn the configuration of the Mandatory Access Controls provided by FreeBSD and how to apply the concepts of the Biba model to FreeBSD.

DNSSEC Part 3: Securing the DNS Hosting Environment
Paul Ammann
DNS security can be distilled into two maxims: always run the latest version of your chosen DNS software package, and never provide unnecessary information or services to strangers. Put another way, keep current and be stingy! The truth is: DNS servers are susceptible to the same types of vulnerabilities (platform, software, and network-level) as any other host on the Internet. This article will provide guidelines for secure configuration of the DNS hosting environment. The author focuses on three areas: content control of the zone file, securing the DNS host platform and software.

Interview with Gabriel Weinberg, Founder of DuckDuckGo
Diego Montalvo & BSD Team

DNSSEC: Threats to DNS Transactions Part 2
Paul Ammann
The threats to a DNS transaction depend on the type of transaction. Name resolution queries and responses (DNS query/response) between DNS clients (stub resolver or resolving name server) and DNS servers (caching/resolving name server or authoritative name server) could involve any nodes in the Internet. Paul, in his article, looks at protocol-based threats to the operation and administration of DNS.

Anatomy of a FreeBSD Compromise Part 6
Rob Somerville
While it is impossible to secure a server against every possible form of attack that the dark side may muster, by taking defensive steps the system administrator can make life exceedingly difficult for the hacker and can delay if not totally avoid a successful attack. Rob claims that while many of the suggestions are probably second nature to most admins, it cannot be stressed enough with busy schedules and tight deadlines the importance of preventative maintenance which has a tendency to slip down the priority list. Rob also examines some techniques that can assist in identifying and delaying attacks.

Using Qjail to set up the basejail
Benedict Reuschling
FreeBSD’s jail system offers process isolation within a separate environment in order to secure the host system. In case of a compromised service, only the jail running that service is affected. In a similar fashion, ZFS allows the creation of a separate filesystem for each jail. Benedict, in his article, explains how jails can be quickly instantiated using a third party wrapper script called Qjail.

PostgreSQL: Server-Side Programming Part 2
Luca Ferrari
Luca claims that one great advantage of PostgreSQL is that it can run functions written in several foreign languages other than pure SQL and its extension plpgsql or the standard C. There are extensions that allow developers to write procedures using Java, Perl, Python and even Bash-like scripting! In this article Perl will be used as a language for both triggers and procedures showing how PostgreSQL can be flexible for server-side programming.

Synchronization Problems or: How I Learned to Stop Worrying and Love the Sleep Mutex
Joseph Kong
When two or more threads executing on different processors simultaneously manipulate the same data structure, that structure can be corrupted. Fortunately, FreeBSD contains multiple solutions to this problem. Joseph addresses his article to the problem of data and state corruption caused by concurrent threads.

ZFS Madness with BEADM - How To
Sawomir Wojciech Wojtczak (vermaden)
Some time ago Slawomir found a good, reliable way of using and installing FreeBSD and described it in my Modern FreeBSD Install 1 2 HOWTO. Now, more then a year later he come back with his experiences about that setup and a proposal of newer and a lot better way of doing it.

A Fresh Look at the Warden for PC-BSD 9.1
Kris Moore
For the PC-BSD 8.x series, new jail management software named “Warden” was first introduced. This software provided users a brand new graphical method of managing FreeBSD jails on their desktops. For 9.1 Warden has been given a complete makeover, and incorporated directly into the base system. Read the article to find out what are the new features that make PC-BSD 9.1 more versatile than ever for jail administrators and users.

Intro to DTrace
Carlos Atonio Neira
Sometimes you wish you had a comprehensive tool for profiling and debugging without having to maintain a chain of tools, merge their outputs and put some glue here and there to extract meaningful information from it. We now have a tool called DTrace, originally developed by Sun. From this article you will find out how to setup DTrace in your Freebsd box. The author will test also some of the providers available for DTrace and see the output.

A Web Application Firewall for Nginx
Benedikt Niessen
When servers got compromised web applications present themselves very often as the entry point. In most cases the reason is an outdated script with known or unknown vulnerabilities or an in-house development which is not properly validating submitted data. Well this is nothing new to you, I hope. The questions is what we can do to prevent this. By reading this article you will learn how to set up a high performance, low maintenance Web Application Firewall in NGINX. This what you will find in this article is just a sample of what you can read in a new book written by Benedikt Niessen. Unfortunately, published in German, but who knows – maybe soon the english edition will be available as well.

Introducing EasyPBI – Making PBI Modules With a Few Mouse Clicks
Jesse Smith
In this article we are going to talk a bit about Push Button Installer (PBI) packages and how we can quickly create these packages from existing software in the FreeBSD Ports Collection. The tool we will be using to facilitate the creation of these packages is called EasyPBI and it can be installed from FreeBSD Ports.

Mysql-zrm: Enterprise Level Backups for MySQL
Giovanni Bechis
Setting up MySQL backup and restore processes typically takes up a lot of a DBA’s time and attention. With mysql-zrm we can setup a backup strategy without the need of creating complex custom shell scripts.Once we have our MySQL server up and running we need a backup strategy to save our data. Instead of using complex scripts written around mysqldump we could use a software that has many feautures to backup our databases and that is easy enough to deploy.

Anatomy of FreeBSD Compromise (Part 5)
Rob Somerville
In the penultimate part in our series, we will compromise a FreeBSD server using different techniques. The *BSD family are some of the most secure operating systems available today. Security is very much a fundamental philosophy and mindset, as it is very difficult to implement once software is written. Earlier versions are not so secure (unless patched) so I have created another FreeBSD 7.0 test server, as well as our 6.1 and 5.0 hosts. Let’s see what happened…

Hardening FreeBSD with TrustedBSD and Mandatory Access Controls (MAC)
Michael Shirk
Most system administrators understand the need to lock down permissions for files and applications. In addition to these configuration options on FreeBSD, there are features provided by TrustedBSD that add additional layers of specific security controls to fine tune the operating system for multilevel security. From this article you will learn the configuration of the Mandatory Access Controls provided by FreeBSD. You fill also find out how to apply the concepts of multilevel security model to FreeBSD.

Security Best Practice for DNS Servers
Paul Ammann
What happens when a trusted server turns out not to be so trustworthy, whether by accident or by intent? Many client machines are only configured with stub resolvers and use trusted servers to perform all of their DNS queries on their behalf. In many cases, the trusted server is furnished by the user’s ISP and advertised to the client via DHCP. Besides accidental betrayal of this trust relationship — whether by server bugs, successful server break-ins, etc. — the server itself may be configured to give back answers that are not what the user would expect.

Here Comes the Cloud
Diego Montalvo
In the past couple of years the term “cloud” has been on every tech news headline from companies offering “cloud” computing or start-ups running killer “cloud” based services. After a lot of thinking and rewriting I decided “cloud” can mean different things, it all depends on how it is being referenced. For example “cloud” by itself is short for Internet or long for web. (…) Cloud-computing has also began to infuse itself into different BSD flavors: Amazon’s Elastic Compute Cloud (EC2) offers users the choice of FreeBSD and NetBSD AMIs (Amazon Machine Instances). Where as RootBSD offers users a choice of BSD on Xen based virtual private services with full technical support.

Developing Applications Using mport
Caryn Holt
In the February issue, you saw how to use the mport system as an end user. In MidnightBSD, you can access the mport features as a developer and add support for mport to your existing C, C++ or Objective C application. (…) The mport library allows developers to integrate some or all of mport features into their own applications without calling exec(). This article is just an introduction to the many features available to MidnightBSD application developers. I would recommend going to the MidnightBSD website for further information.

Taking the BSDA Certification Exam
Dru Lavigne
The first article in this series (in the February 2012 issue) addressed some common misconceptions about certification and described why you should be BSDA certified. The second article in this series (in the March 2012 issue) discussed how to prepare for the BSDA certification exam. This article will provide some background information on how the exam is delivered and why. It will then describe where to take the exam and how to arrange for an exam if there currently isn’t an examination event or testing center near your location.

Installing OpenBSD 5.0 on VMware Server
Toby Richards
We’re going to install OpenBSD 5.0. With the information in this article, you’ll learn how to install it both on your own computer and via VMware Server. For my example, I’ll use my own Bsdvm.com account.

Installing FreeBSD on Amazon AWS EC2 Cloud Services
Diego Montalvo
I have had an AWS account since Amazon first introduced the Elastic Compute Cloud (EC2). But to be honest back in the day it was fairly cryptic to get an instance running, the AWS web interface was in it’s infancy and documentation was limited. From this article you will learn how to install a FreeBSD on Elastic Compute Cloud and run a Virtual Server on the Cloud.

PostgreSQL: Replication
Luca Ferrari
In the previous articles we saw ho to set up a PostgreSQL cluster, how to manage backups (either logical or physical) and how internally transactions work. In this article we will see how it is possible to replicate a running cluster to another instance in order to have a fully mirrored and active “stand-by” node. Most of the configuration will be done by simple shell scripts in order to both show required instructions and to allow readers to replay several time the experiments. Please note that configurations shown in this article are for didactic purposes only, and represent only a starting point for replica environments.

Interview with Mark Price
Diego Montalvo & BSD Team
I don’t think cloud is anything specifically new. I think its just a term that describes the trend in businesses outsourcing more IT functions. My experience with IT people in general is that IT people are very possessive and territorial, wanting to have lots of servers doing lots of things in-house. The ‘cloud’ idea just says “OK, we are going to outsource some of this boring technology stuff and instead concentrate on what’s really important to us”. Read the interview with President of Tranquil Hosting and owner of RootBSD to find out what is his view on the Cloud.

The Greater Benefits of Open Source Software
Paul Ammann
In contrast to proprietary software produced by most commercial manufacturers, Open Source software is written and perfected by volunteers, who freely share the programming code that would otherwise be kept secret. (…) Let’s address Open Source as a market phenomenon, stating some of the basic facts and seeking to clarify some misconceptions that have emerged in recent treatment of the issue.

MaheshaBSD-2.0 — What's New On The Lake Manasarovar?
To readers who have not yet come across the 2010 May issue of the BSD Mag, where MaheshaBSD-1.0 was first introduced, I reiterate that MaheshaBSD is a free homemade project – a Live CD based on FreeBSD that puts together the Hindu feel and FreeBSD. A few things give it this touch – for example, a possibility to use 4 keyboard layouts also with Devanagari (an Indian script used for writing Sanskrit and contemporary Indian languages) and IAST (transliteration of Sanskrit), the author’s Xmodmap solution. Its name is derived from Mahesha, one of the names of Lord Shiva. The name Mahesha (MaheshaBSD) was chosen because Lord Shiva is armed with the same weapon as FreeBSD – the trident.

GhostBSD: A Brief Overview
GhostBSD was created to encourage the use of FreeBSD users with little experience, and also for those curious who want to learn freebsd in a simple, or for those seeking a more robust alternative to the current options available in Linux kernels. An operating system with graphical environment, simple and useful, as is implemented in GhostBSD, it helps enthusiasts to take their first steps, provides more security and incentive to experiment.

How Do I Study for the BSDA Certification?
The previous article in this series addressed some common misconceptions about certification and described why you should be BSDA certified. This article will discuss how to prepare for the BSDA certification exam.

GDB(1) and Truss for Debugging
Sometimes you are lucky to have the source code for the program you need to debug. However, there are times when the source code isn’t available. When all hell is breaking loose, what do you do? On your unix machine there are tools that can save the day. OpenBSD, FreeBSD and NetBSD all have the ktrace utility for following the various kernel related activities of a given process. FreeBSD has a tool specifically for tracing system calls. It’s called truss(1) and when used together with gdb(1) it can give you a clearer view into a black box.

PostgreSQL: MVCC and Vacuum
In the previous article readers have seen how to quickly install and configure a PostgreSQL cluster, as well as how to do logical backups, using pg_dump(1) and physical backup (with particular regard to Point In Time Recovery). This article shows a little more about PostgreSQL internals and how it exploits MVCC for high concurrency. Readers will also learn about the importance and usage of vacuum for regular maintanance.

Beowulf Clusters with DragonflyBSD
There are two types of computing clusters: High availability (HA) clusters are designed so that if one computer fails, the other(s) take over its job. HPC clusters enable many computers to do the same job together so that processing power is increased. We’re going to focus on the latter. An HPC cluster on consumer grade hardware is called a Beowulf after the classic poem written sometime between 700 – 1000 AD. Beowulf technology is the result of a 1994 cooperative research project between NASA and several universities. Since DragonflyBSD development focuses so much on performance, it seems the best option for a BSD Beowulf. In fact, HPC clusters are one of the stated design goals of DragonflyBSD.

Have you ever needed to set up a VPN for Microsoft Windows or Mac OS X users? From this article you will find out how to configure OpenBSD and npppd to provide PPTP and L2TP VPN’s in a few easy steps. In January 2010, npppd was imported into the OpenBSD source tree and this software can act as a PPTP/L2TP VPN server and also as a PPPOE server. Because npppd is still under active development and still missing some features, it is not linked to the standard build yet, so to install the program you first need to build it from OpenBSD source tree.

Anatomy of a FreeBSD Compromise (Part 4)
Continuing our security series, we will look at the vulnerabilities on our test network. From the last article, we discovered that to penetrate a system we continually needed to move from the general to the specific, and to identify the most vulnerable system on our network depending on what services were running on it.

Customizing Your PC-BSD 9.0 Desktop
One of the most important new features of PC-BSD 9.0 is the ability to customize your desktop with a variety of different FreeBSD packages, such as desktops, window-managers, servers, drivers and more. This is done through the new pc-metapkgmanager utility and it’s front-ends, which allows users to quickly and easily select a bundle of packages, such as KDE or GNOME, to install. This ability in effect allows a user to deploy a custom FreeBSD based desktop without the hassle of using the command-line and manually resolving dependency issues. Lets take a look at how this can be used in the new PC-BSD 9 desktop.

The MidnightBSD Package Management Tools
One of the most tedious tasks in setting up and maintaining a personal computer is installing software applications. The BSD community has historically handled this by providing users a ports system to compile software and later some package management software. This approach has worked well for power users. The Linux community has built some user friendly package management tools with command line and graphical user interfaces. In minutes, one can install a new web browser or word processor.

Why Should I Become BSDA Certified?
If you are reading this magazine, you are interested in learning more about BSD systems. Perhaps you have seen this magazine’s ads for BSD Certification and want to learn more about this certification program or perhaps you think that certification is not for you. This article addresses some common misconceptions about certification and describes why you should be BSDA certified. This article outlined some of the benefits provided by a psychometrically valid certification program as well as some tips for learning the skills needed to pass a certification exam.

What Can’t You Do On The command-line?
Most of us have all grown accustomed to some form of true graphical interface to our computers. But there’s always that group of so-called `geeks’, which remain to work at a simple 80?24 console. But that’s just for geeks, or is it?

PostgreSQL: From Installation to PITR
“The most advanced open-source database available anywhere”, this is the comment for the PostgreSQL package. PostgreSQL is an enterprise-level ORDBMS very stable and reliable, with a rich set of features that make it competing with well known commercial databases. PostgreSQL is released under a BSD license, has a very comprehensive documentation and is maintained by a set of database experts around the planet. In this article you will learn how to install and set up a PostgreSQL cluster, how to interact with the system and how to make backups of your databases.

OpenBSD with SUN JAVA & Netbeans
This article is designed for Java developers who wants to have a good operating system for their works. You will learn how to setup SUN Java system and Netbeans on your OpenBSD desktop.This article is based on OpenBSD 5.0 version.

Data Classification Policy
A good sysadmin realizes that security is more than firewalls, encryption, patching, and other technical considerations. One common saying is: “The only secure computer is one that’s not plugged into the network.” Humbug! A clever intruder will easily trick the user into plugging that Ethernet cable back into its socket. The weakest point in any network is the human element.
I want to share with you my data classification policy.

Load Balancers. Enterprise Load & Service Availability
The world is a complex place. A term that means one thing to one person may mean something completely different to someone else. Take Load Balancers for example. How many different Load Balancers can you think of?

Anatomy of a FreeBSD Compromise (Part 3)
Continuing in our security series, we will look at the tools essential to securing and exploiting systems.In the previous articles, the author looked at the culture and processes behind hacking exploits, as well as some possible real-life examples. In this article we will look at some of the tools used to penetrate, test and secure devices as well performing analysis and discovering vulnerabilities. While the examples here are non-destructive, it is recommended that these tests are carried out on a private test network and definitely not on the Internet or without your employer’s approval. To do so may well be in breach of your ISP’s or employers Acceptable Use Policy and could lead to legal action against you.

Counting Our Losses
2011, a hefty year as they all say. Even Discovery Channel has specials on the events of this year. The devastating earthquake in Japan, the war on terrorism finally claimed their hard sought-after victim and even the untimely death of Steve Jobs has a special. But what about the real heroes? The heroes behind the screens, outside of popular media?

What’s New in FreeBSD 9.0
FreeBSD 9.0-RELEASE introduces many new features which benefit FreeBSD users, application developers, and companies that use or base their products on FreeBSD. This article provides an overview of some of these features, including references to additional information.

Home Brew Captive Portal With OpenBSD
Have you ever used a public wireless network that has a splash screen such that you have to agree to certain terms before going to the Internet? The author of this article will show you step by step how to build one of those using OpenBSD’s Packet Filter (pf).

Puppet on FreeBSD
This article aims to jumpstart a system administrator on how to use Puppet (configuration management tool), to manage server’s configurations, particularly on FreeBSD. From this article you will find out what is Puppet and how to deploy servers by using it.

FreeBSD IPS With Snort Inline
A number of articles have been written covering the basic configuration of Snort in IDS mode on the different BSD operating systems. One feature that is not typically discussed is Snort’s ability to integrate with ipfw that allow for inline IPS mode on FreeBSD. This article covers the basic configuration of Snort in IPS mode on a FreeBSD server.

malloc(9): The Kernel’s General Purpose Memory Allocator
The release of 4.3BSD in 1988 introduced a new memory allocation mechanism intended to be general enough to effectively meet the needs of diverse kernel subsystems requiring dynamic memory allocation. This article gives an overview of malloc(9) and its corresponding function free(9) and explains how this type of dynamically allocated memory is managed within the kernel.

Keeping FreeBSD’s Base System and Packages Up-To-Date
In tis article the author deals with an ungrateful topic of keeping both FreeBSD’s base system and installed packages up-to-date. Read it to learn more about upgrading/updating FreeBSD system, adding/removing packages and get some knowledge about Ports concept and its genaral usage.

Anatomy of a FreeBSD Compromise (Part 2)
Continuing in our security series, the author will look at the ways that “the bad guys” can gain access and what can be done to mitigate this risk. As mentioned in the previous article, the author highlighted this time some of the reasons why servers and systems are inherently insecure and why it is impossible to 100% secure any system. In this article, he will examine some of the common techniques used to gain control and what we can do to mitigate the risks.

Elephants in Prato
The first official Italian PGDay was organized by a bunch of volounteers and passionates, including the author, in 2007. At that time ITPUG did not exist at all. The conference catch the attention of several other PostgreSQL related communities, including Japan PostgreSQL Users’ Group (JPUG), and had a lot of special guests including members of the core team. This quickly lead the organizers to extend the conference from one day only to a two days event.

Commissioning FreeBSD with the Drupal Content Management Framework – Part 1
With nearly 6000 modules and PHP support Drupal offers a sophisticated web development platform as well as a thriving community. Drupal, originally conceived by Dries Buytaert, has a reputation of being an extremely capable DContent Management System (CMS) albeit with a steep learning curve. While many criticisms concerning the complexity of the interface will be addressed in the forthcoming Drupal 7 release (which is currently in the alpha stage), Drupal 6 excels in stability, flexibility and high quality code. The developers also subscribe to a transparent policy towards security issues, and have a dedicated security team which ensures that core modules remain high quality. Used as the basis of many high profile sites.

Do you know about troubles that could bring this simple transaction like WiFi network card purchase?Some might ask – is it necessary to buy a WiFi-card instead of a simple AccessPoint (AP)? At first glance you can figure out that there exist the fine models of ADSL-modems with wireless capabilities and that could work as AP. However, it should be noticed that: a) not all home connections to an Internet-provider go through a „copper” like phone- or cable-line; b) you simply need to add a WiFi-capability to an already working gate; c) a WiFi-card itself costs several times cheaper of AP.

Interview with Dirk H. Schulz

Installing a Citrix Client on FreeBSD
As our computing needs change, so does our criteria for selecting an operating system. Today, my job and my family are in different cities.

Writing shellcode for Linux and *BSD
A shellcode is a sequence of machine language instructions which an already-running program can be forced to execute by altering its execution flow through software vulnerabilities (e.g. stack overflow, heap overflow or format strings).

How To Convert Text to Voice Using Festival and Lame in FreeBSD
In 2007 I built a web-based IM/ Chat Service which was later launched as an iPhone web app. Making a long story short I retired the service in 2008 and that was that.

FreeBSD Squid proxy with Parental Controls How-To
Traditionally, web pages were served via a webserver such as Apache and transmitted via the network on port 80 to a web-browser.

Network monitoring with Nagios and OpenBSD PART 2
So our OpenBSD-based network now includes redundant firewalls (http://www.kernel-panic.it/openbsd/carp/index.html), domain name servers (http://www.kernel-panic.it/openbsd/dns/index.html), a mail gateway (http://www.kernel-panic.it/openbsd/mail/index.html) and a web proxy cache (http://www.kernel-panic.it/openbsd/proxy/index.html).

Introduction to MidnightBSD
MidnightBSD was founded in 2006 by Lucas Holt. The project is a FreeBSD 6.0 fork with an emphasis on creating a desktop focused BSD.
While there are other BSD desktop projects (most notably PC-BSD and DesktopBSD), we wanted to create an entire desktop centered BSD from the kernel all the way up to the standard applications. We want a BSD that a grandmother could install and use.

The FreeBSD Ubuntu challenge
FreeBSD makes a great server, but can it rise to the challenge of running Compiz as a workstation?
One of the many criticisms of Open Source software (indeed even FreeBSD) is that it is not ready for the desktop.

Network monitoring with Nagios and OpenBSD PART 1
So our OpenBSD-based network now includes redundant firewalls, domain name servers, a mail gateway and a web proxy cache. (Read previous issues of BSD Magazine) All the services provided by these machines are particularly critical and can’t afford even minimal downtime. Redundancy may give us the time to recover a failure before having angry users trying to knock down our door, but it doesn’t free us from the responsibility to detect and solve ongoing problems.

Replacing Microsoft Exchange Server

Maintenance Systems over BSD
I was talking in previous articles about how to run applications widely used in the Industry that can be supported by BSD apart of classical IT services.
As clear example of this is SAP Suite. SAP covers all possible asset management to control the cost related to production and also maintenance but as per tighted cost in investments today, the Plants must run 24/7 with maximum reliability and productivity possible.

Low Resource PCs with FreeBSD
FreeBSD is my pick for best modern operating system to use on older PCs. I can’t believe how many used PCs end up as landfill while students, educators, low income families and others go without a computer at all.

Making the Unknown Giant Visible and Known

Introduction to NanoBSD
NanoBSD is a tool developed by Poul-Henning Kamp phk@FreeBSD.org. It creates a FreeBSD system image for embedded applications, suitable for use on a Compact Flash card (or other mass storage medium).

Secure Your Wireless with IPsec
Wireless access is all the rage. Wireless this, wireless that. Hot spots are turning up everywhere. Many are free. Many have absolutely no security. There are several in my neighborhood. I have no idea who is running them, but at least one is wide open.

Redundant firewalls with OpenBSD, CARP and pfsync
Firewalls are among the most critical network components, since their failure may cause entire groups of machines to remain offline. The damage may range from the public (web, mail, etc.) servers to become unreachable to the outside world up to being unable to surf this web site!

I have a very large PHP/MySQL application running on FreeBSD 6.0. Before we go any further let’s get it out of the way: yes, I should upgrade to a more current version, but when you have a big system running a lot of sites in a live environment, well, you often end up a couple of versions behind the most recent stable release.

BSD File Sharing – Part 4. SSH

MaheshaBSD: A Live CD Project From The Lake Mansarovar
MaheshaBSD is the name for a Live CD project. Why Mahesha? What does it mean? Mahesha is one of the 1008 names of Lord Shiva – Supreme God of the universe who stands above all gods. This name was chosen because Shiva’s weapon is the same as the FreeBSD’s one – the trident. There is yet another important correlation – supremacy of the BSD code, which (as many IT professionals believe) stands supreme above all operating systems. The connection of Lord Shiva and BSD is therefore logical.

OpenBSD as a Primary Domain Controller
Once a Windows-based network grows beyond around a dozen computers, setting up a Primary Domain Controller to simplify and centralize the management of users, computers and network resources becomes a must. But does the Domain Controller necessarily have to be a Windows machine, thus meaning the end of our project of a completly OpenBSD-based server network?
Of course not! Once again, OpenBSD comes to our rescue and, with the help of a few additional pieces of software, it will turn into a full-blown, secure and reliable Domain Controller.

FreeBSD MySQL Clustering How-to
The PHP, MySQL and Apache stack is a very popular implementation on standalone BSD servers but in demanding high availability [HA] environments the twin spectres of redundancy and fail-over rear their heads. In these scenarios, it is essential to eliminate the single point of failure which is the enemy of 100% uptime.

Last time I wrote on SAMBA on different BSD’s. This time I am going to dedicate the article of the series to FTP. Some people do not know that the FTP protocol is the true BSD heritage, as it originated in the 1970’s at Berkeley University, so it is the right thing to dedicate it some space in the BSDMag anyway.

Exploring HAMMER
One of DragonFly’s features is a new file system, called HAMMER. HAMMER has, to quote from the man page, instant crash recovery, large file systems spanning multiple volumes, data integrity checking, fine-grained history retention, mirroring capability, and pseudo file systems HAMMER is available by default on DragonFly BSD.

Embedded OpenBSD
Unix-like operating systems aren’t picky at all. Despite the extreme physical conditions, they can take root on those old computers where most (proprietary) operating systems risk extinction and help them, after years of faithful service, to start new lives as firewalls, routers, proxies…
But sometimes this is not enough: servers must be reliable and old computers aTahomare (guess what?) …old, and this increases their risk of disease. That’s why embedded systems are a great option: they are (relatively) inexpensive, silent, small, reliable… What else could you need? Ok, you have to learn to cohabit with very basic hardware, but the right OS, with the right configuration, will wallow in it!

Making Sense of Data Management on Intelligent Devices
The demand for embedded devices is growing rapidly, and there is a clear need for development of advanced software to deliver new features on limited hardware. Data management is a critical component in these new software systems. Embedded databases are used by portable media players to store information about music and video, GPS devices to store map data, and monitoring systems to log information. These and other leading-edge industries have learned the importance of managing data reliably with a relational embedded data management system.

BSD in the Industry
After several years of slavery with windows based programs, many programs related with Industry or Engineering are opening the doors to the new trends of UNIX like OS. This is a natural evolution because as the Economy crisis strikes on whole World, the IT infrastructures are also under pressure to decrease at maximum the overall cost.

It is similar to the idea that January 1, 2010 A.D. does not really represent the precise time since the birth of Christ (astronomers have proven this to be off by a few years) but we still use it as a time marker.

In this article, I will demonstrate how to install FreeBSD, configure KDE and sound, install additional software, and find resources to learn more about FreeBSD.

FreeBSD’s bsnmp
Any large datacenter or network uses the Simple Network Management Protocol (SNMP). Many Unixlike operating systems use the Net-SNMP toolkit from http://www.net-snmp.org. While Net-SNMP is a powerful and flexible SNMP implementation available for many platforms, it does not support BSDspecific functions.

Pushing BSD as an open source desktop
It may come as a surprise for the majority of computer users, but open source operating systems have a long and solid track record. They form the backbone or crucial building blocks of the ICT infrastructure of companies and organizations. In a world where desktop computing has equaled Windows for such a long time, the ascent of the open source desktop may appear as something new but those desktops are firmly rooted in decades of development.

PC-BSD overview
Everybody wants a stable and secure operating system and wants it at the cheapest possible price. In most cases it is GNU/Linux. But what about when you want something different, something not quite like GNU/Linux? Then you would do well to have a look at FreeBSD. In this article I will take an overview of a certain FreeBSD distribution called PC-BSD.

Sguil 0.7.0 on FreeBSD 7.0
Sguil (www.sguil.net) is an open source suite for performing Network Security Monitoring (NSM). NSM is the collection, analysis, and escalation of [network-based] indications and warnings to detect and respond to intrusions. The author has been using Sguil on FreeBSD since Sguil’s developer, Robert “Bamm” Visscher, created the application in 2001.

systems to boot.

Keep smiling, waste spammers’ time
When you are in the business of building the networks people need and the services they need to run on them, you may also be running a mail service. If you do, you will sooner or later need to deal with spam. This article is about how to waste spammers’ time and have a good time while doing it.

Defense in Depth and FOSS
Protecting your infrastructure is a tough job and one that requires a lot of attention. Meanwhile a lot of new tools are being published that can protect and some that can attack. This war between good and bad can take up a lot of resources, and how much is enough.

BSD 1/2008 NetBSD on the NSLU2
If you own a Network Storage Link (NSLU2) from Linksys, you have a nifty, relatively inexpensive device with an Arm-5TE-compatible Xscale processor, 8 MB of flash memory, 32 MB of SDRAM, two USB ports, and a 10/100 Ethernet port.

OpenBSD pf – the firewall on fire
In this article we will take a look at the king of firewalls – OpenBSD pf. pf has an interesting history as it was developed due to some interesting licensing problems with the firewall code in OpenBSD at that time. This happened well over six years ago. A genius named Daniel Hartmeier set out to hack the
OpenBSD kernel in a beautiful Swiss town and something that began as a patch to the kernel to add firewalling functionality has today become the ultimate tool not only for performing the tasks of a firewall but also for QoS, spam control and traffic normalization.

Instant Messaging with Jabber/XMPP
Instant Messaging-What a Concept! To be able to talk, (or chat as it is commonly called), to someone on the other side of the planet in real-time. WOW! In the 1970’s, when instant messaging first appeared, it was used as an inter office tool, for users of systems like UNIX, to leave messages for others using the same machine, working it way up to a device to communicate with others in the local network.

Interview with FreeBSD developer
One of the major improvements in FreeBSD 7.0 is the performance increase that every owner of MP machines is experiencing. How did they get such a great result? I have interviewed Jeff Roberson, the creator of the ULE scheduler, to learn more about the work done by FreeBSD developers in SMP land.
