Released: PBI Builder 2.4

pc-bsd logo 100x100A small update to the PBI Builder software, version 2.4, has been released.

This version adds a few new variables to the module creation process, which allows developers to pick “target” ports they wish to have autopopulated and added to the resulting PBI file.

Programs under PC-BSD are completely self-contained and self-installing, in a graphical format. A PBI file also ships with all the files and libraries necessary for the installed program to function, eliminating much of the hardship of dealing with broken dependencies and system incompatibilities. PBI files also provide developers and packagers with advanced scripting and user interaction in an entirely graphical format, making the entire install procedure similar to what a user would expect from other popular graphical operating systems.

For full details, please take a look at the changelog, and the wiki page.

Released: m0n0wall 1.236

m0n0wall logo 100x100M0nowall version 1.236 was released last week in order to address a security issue in the ISC DHCP client. If you don’t use the DHCP client on WAN or if you trust the DHCP server(s), there’s no need to upgrade.

1.236 also includes a few captive portal fixes imported from the 1.3b branch, so if you use the captive portal, that would be another reason to upgrade.

Microsoft backed Barrelfish OS goes “open source”

Microsoft has released the first snapshot of the Barrelfish operating system, an operating system written especifically for multicore environments.

The Barrelfish team, a group of researchers from Microsoft Research Cambridge and the technology university ETH Zurich, says it is “motivated by two closely related trends in hardware design: first, the rapidly growing number of cores, which leads to a scalability challenge, and second, the increasing diversity in computer hardware, requiring the OS to manage and exploit heterogeneous hardware resources.”

Tthe project has been under way for about two years and builds on ideas researchers have had for years about how system will evolve to keep up with hardware advancements.

In Barrelfish, each core has its own kernel and does not share memory as it does in Windows or Linux. Instead, the cores communicate by passing messages, what researchers term a “multikernel” model.

Barrelfish is still in a research phase and its code released under the 3-clause BSD-style Open Source licence.  The software is free to download.

We all know how Microsoft has dealt with and treated opens source software in the past. Michael Kerner, from internetnews.com, remarks:

As a BSD style license and without any clear open/public source code repository, this isn’t an open source operating system like Linux or even say FreeBSD. The way I see it, open source here is a means of distribution and a way for people to openly see what the researcher have done and not necessarily as a means of collaboration or contribution.

Report from EuroBSDCon 2009

eurobsdcon2009Nik Clayton, site reliability engineer at Google,  has written up an account of what he’s seen, heard and done at EuroBSDCon 2009.

I’m no stranger to EuroBSDCon. After attending several very successful conferences in the US, three FreeBSD contributors and I decided that Europe needed a BSD conference too. In November 2001 we were proud to host 160 or so delegates in the first European BSD Conference. Over the last couple of years I haven’t been able to keep as up to date with the latest developments in the BSD world, so I was very interested to attendEuroBSDCon 2009, organised in collaboration with the UK Unix User Group.

With the conference split in to several tracks it was impossible to attend every talk, so I decided to focus primarily on those that talked about how BSD systems were helping people solve problems in the real world. Links to all the papers, slides, and in some cases audio from the presentations can be found at conference schedule page.

The first talk I attended was “How FreeBSD Finds Oil,” given by Harrison Grundy. Harrison runs a consultancy company in the US providing clustered computing systems to oil and gas companies.

Continues here…

Most reliable hosting sites – September 2009

netcraft logoNetcraft‘s monthly reliability monitoring showed a bit of a mixed picture in September. Linux took the number 1 place.  IN the top10 FreeBSD took places 3, 7 and 10.

DataPipe (who use FreeBSD) was one of the most reliable hosting company sites in August, and only narrowly missed out on the same achievement in September. DataPipe has shown some good results over the past six months, notching up five top-ten appearances, including three first places.

All the details here.

FreeBSD: Like Linux

Kuvaton has a picture of operating systems, comparing them with cars. Or should I say, a picture of cars compared with operating systems?

FreeBSD: Like Linux but takes more cargo on the expense of being less customable.

os_cars

I like the VMS one. What do you think of these comparisons? OK, fair or ridiculous?

This picture reminds me of the OS user mugshots that I posted a while back.

BSD Mag issue 6 – BSD Security & OpenBSD 4.5

bsd magazineThe 6th issue of BSD Mag is now available. The topic for this month is BSD Security & OpenBSD 4.5.

Interested in the BSD Mag but don’t want to commit to a subscription yet? Have a look at these 3 free issues (PDF) and decide.

This is the table of contents of the latest issue:

Installing OpenBSD

OpenBSD 4.5 is the latest version of OpenBSD released in May, 2009. This article will walk you through its installation in great details. For a quick start boot the attached DVD with OpenBSD 4.5.

Postgresql, shared memory and BSD

This series of articles will compare a basic installation of Postgresql on various flavors of BSD, and compare the performance between them given similar shared memory settings.

Triple booting Windows 7, Ubuntu 9.04 and PC-BSD 7.1

In this article we will give a step-by-step guide to installing three different operating systems on the same hard drive.

BuildaSearch a FreeBSD Web Service

BuildaSearch is a web service which allows users to build a custom search engine or site search in less than five minutes. No coding skills are necessary when building a custom search. Users can customize their colors, backgrounds, logos, and search results.

Web Servers for Embedded NetBSD

Web-based user interfaces have become ubiquitous for all sorts of electronic gear these days. If you are building a network-capable device, chances are you will want to add a web server to your device’s software, as well – it’s generally cheaper than a hardware interface and far easier to change or update.

Out-of-the-box sshfs on NetBSD 5.0

Sshfs makes it possible to mount a remote directory tree onto the local machine. Only ssh access is required for this.

FreeBSD Security Event Auditing

Security is increasingly a hot topic in systems administration. Vulnerable systems get patches, firewalls get set up and password policies are enforced. But in the end, all these measures cannot eliminate the risk of a system break-in. They can only reduce it.

Securing OpenSSH server

OpenSSH is free implementation of SSH suite. Many of us use it on a daily basis and got so used to it we couldn’t imagine our lives without it.

Staying Secure using PC-BSD

“Help! Pop-ups are destroying my computer!” I cannot count how many times I have heard those words come from my brother’s mouth.

Stop Hackers With Protection Script

I suppose you have a border server that is freely accessible from the internet or you just want to have a secure machine. Whichever the case is, I will tell you my story.

OpenBSD on the Sharp Zaurus

If you look at the OpenBSD Platforms page ( http://openbsd.org/plat.html ) you’ll see Zaurus down at the bottom. Is it there just so that the OpenBSD team can safely say that they support a multitude of platforms, from Alpha to Zaurus?

Questions and Answer Session of the BSD Certification Group Community

Recently, the BSD Certification Group (BSDCG) asked via their mailing lists for questions regarding the BSDCG or the BSDA exam, offering to answer them in this issue of BSD Mag.

Interview with Albert Whale

My name is Albert Whale, the President of ABS Computer Technology. I am a resident of Pittsburgh, PA, and I work with my company on Security and Consulting opportunities on an international basis.

Interview with Matt Juszczak

Recently I had the opportunity to sit down with Matt Juszczak creator of BSDJobs.net and ask him some questions about the project. I would like to thank Matt for taking the time out of his busy schedule to talk with me about the project. The following is a synopsis of that Q&A session.
