(Free)BSD myths dispelled

January 15, 2008 By iXsystems Leave a Comment

FreeBSD myths dispelled As the BSD projects (DragonFlyBSD, FreeBSD, NetBSD, and OpenBSD) have grown in size, a number of persistent myths have grown up around them. Some of these are perpetuated by well meaning but misguided individuals, others by people pursuing their own agendas.

This page aims to dispel those myths while remaining as dispassionate as possible.

BSD, the more Unix-like OS

November 1, 2007 By iXsystems 2 Comments

This is an interesting blog post looking at the BSD as a viable alternative to Linux. The BSDs are less hyped and are in some areas superior to Linux:

“The BSDs have been around for a long time – longer than Linux. But they have received much less attention than Linux in the press because they have fewer noisy supporters. Nevertheless, they continue to thrive, because of their similarities to, and differences from, Linux. Like Linux, the BSDs are free, fast and have a variety of software available for them. In addition, BSD kernels tend to be more stable than Linux kernels, BSDs run on a wider variety of hardware and have fewer security issues.

But where the BSDs tend to really shine is in networking. TCP/IP speed tests run on identical hardware often show the BSDs to be faster than Linux. While the Linux community has focused on enabling Linux to use more esoteric hardware, the BSD community has worked on making the network infrastructure faster and easier to extend. This has caused a number of network hardware vendors to use customized versions of BSDs, particularly NetBSD, as the internal operating systems of their commercial products.

As the lesser-known players in the free operating system market, the BSD development groups have had more opportunity to work on the core of their products. FreeBSD has the largest market of the BSDs and gets the most development interest. NetBSD runs on an incredible variety of CPUs, including some systems that leave even the fastest Intel chips in the dust. OpenBSD’s main focus is security, and it attracts developers for whom that is the main concern.

…

It is well known that many large Internet service providers use one of the BSDs (FreeBSD) to run their production mail and Web servers. It is common to find BSD-based Internet servers that have not crashed or been rebooted in years.

… any shop that is considering Linux should also take a look at the BSDs, particularly if they want stability and less excitement in their operating system.”

Differentiating Among BSD flavours

May 26, 2007 By iXsystems Leave a Comment

This website deals mostly with FreeBSD and systems derived from or based on this superb operating system. However it’s also good to be aware of other BSD systems that are around and the reason why they exist or why have been developed: OpenBSD (secure by default – the world’s most secure OS), NetBSD (runs on nearly every platform imaginable, including a bread toaster! and in some sense Apple’s MacOS X. (See Unix family tree here)

There’s a good article on Serverwatch.com explaining the history, the differences between and common features of the 4 main BSD systems.

Organizations that want to use a public Unix variant have two solutions from which to chose: Linux and BSD. The much talked about Linux camp contains a variety of distributions that include different utilities and tool sets. The same is true of the less frequently covered BSD camp. This article compares and contrasts the four main BSD variants and offers recommendations for both server- and desktop-based solutions.

There are four main BSD variants. Three of these (FreeBSD, OpenBSD, and NetBSD) are totally free; the fourth (Mac OS X) is technically the core part of an operating system that most wouldn’t even consider a BSD variant. To understand the differences between the various versions, let’s briefly recap the history of BSD to understand how the different versions have developed.

Unix and BSD Family Trees

May 24, 2007 By iXsystems 2 Comments

Recently I came across two interesting websites that show an up-to-date family tree of Unix and BSD operating systems, and thought that those of you who are not too familiar with the different Unix and Unix-like systems might find these pages interesting.
