Alexandre Ratchov (ratchov@), OpenBSD developer and composer of one of the extra audio tracks on the newly released audio CD, writes in to tell us how he created the song:

As the "Sonate aux insomniaques" track was just released, I take few minutes to explain how the audio track was produced and where it comes from.

The music is entirely inspired by a poem titled "Sonate aux insomniaques" by Guillaine Dioudonnat. The initial plan, was to work with Guillaine to turn it into a song. But it turned out that the text would add constraints to the rhythm, which would make harder to make the music reflect the universe created by the poem. That's why there are no lyrics.

Kristaps Dzonsons wrote in with an article about how OpenBSD helps him produce better research. Kristaps writes,

It's no secret that OpenBSD is an excellent research platform. From packages(7) for specialised software to out-of-the-box httpd(8), sshd(8), and so on, it's a no-brainer to pop OpenBSD onto a workstation and just get to work.

In this article, I explore how OpenBSD's clean code and sane defaults recently saved the day. For great science!

As Theo de Raadt (deraadt@) announced in a message to the misc and announce mailing lists, pre-orders for the upcoming OpenBSD 5.1 have opened.

Date: Tue, 13 Mar 2012 20:47:24
From: Theo de Raadt 
To: announce@cvs.openbsd.org
Subject: pre-orders activate for OpenBSD 5.1

It is that time again.  I have just activated pre-orders for CDs,
tshirts, and posters for the 5.1 release -- due May 1.

    http://openbsd.org/orders.html

At the same time, I am making available the song that will come out
with the release (hmm, it is still moving out to the ftp mirrors at
the moment, but that is ok).  The song and details of it are linked
from:

And this time there's even more goodies available for you to grab for your collection.

Gabor Pali wrote in to announce and invite OpenBSDers to the upcoming BSD-Day in Vienna, Austria. Gabor writes,

Dear All,

I am glad to inform you that we are again organizing a "DanuBSDCon" (aka. BSD-Day). It is going to be held at the UAS Technikum Wien in Vienna, Austria on Saturday May 5, 2012 as part of the Austrian Linuxweeks (Linuxwochen).

We would like to invite everybody — anybody who is just looking for an excuse to make a short trip to Central Europe, spend a nice weekend in Vienna, join us for a beer, talk about her favourite topic, or meet fellow developers from the region (and from other BSD flavours), or accidentally will not be able to make it to Canada :-)

So, please contact me if you are interested!

In a blog post titled IPv6 NIDS evasion and improvements in IPv6 fragmentation/reassembly, security consultants SI6 Networks report on some experiments they conducted recently in order to test IPv6 fragment handling in various general-purpose operating systems.

While the authors did not say so in so many words, the conclusion is that OpenBSD is ahead of the pack in both RFC compliance as well as sane and secure handling of IPv6 fragments.

Michael W. Lucas writes in with news about his book, SSH Mastery:

The OpenBSD Project is selling SSH Mastery print version as a fund-raiser. If you've been waiting for a print copy, this is your chance.

If you don't need it, you know someone who is still using passwords with SSH. Buy a copy. Slap them soundly with it.

The book is now available from the OpenBSD site. Please visit http://www.openbsd.org/books.html for details

On n’y croyait plus à l’arlésienne, mais cette fois on n’a jamais été aussi proches.. je veux bien sûr parler de rthreads, les threads in-kernel qui remplacent (enfin!?) les antédiluviens pthreads en userspace. Commencés en 2005 par tedu@, laissés un peu à l’abandon par faute de temps/motivation, ils ont été relancés par guenther@, pour être maintenant activés par défaut, juste après le tagging de 5.1. Evidemment, maintenant il faut tester tout ça, rebuilder tous les ports etc, donc des snapshots devraient faire leur apparition rapidement.. enjoy!

Cet article a pour objectif d’expliquer comment installer un bureau Gnome complet sur OpenBSD. Faites simplement # pkg_add gnome Puis, dans /etc/rc.conf, mettez “dbus_daemon” à la variable pkg_scripts : pkg_scripts="dbus_daemon" # startx /usr/local/bin/gnome-session

Introduction Le système des ports a été conçu afin de pouvoir faire fonctionner des applications tierces avec OpenBSD. Ces applications sont portées afin de respecter les exigences du système OpenBSD tel que la hiérarchie du système de fichier. De plus les ports permettent de maintenir plus facilement les applications (installation, suppression, mise à jour) et de garder un système propre. Une application portée est certifiée fonctionnelle. Un ports génère un package qui pourra ensuite être ins…

Cet article a pour objectif d’expliquer comment maintenir son système OpenBSD à jour en suivant la branche -current. Commençons par récupérer les sources de la branche -current : # cd /usr # export CVSROOT=anoncvs@anoncvs.fr.openbsd.org:/cvs # cvs -d$CVSROOT checkout -P src

Cet article a pour objectif d’expliquer comment mettre à jour son système OpenBSD, sa configuration, et ses packages. Il est compatible avec toutes les versions d'OpenBSD. Tout d'abord, on va se placer dans le dossier personnel de root, et télécharger le fichier appelé “bsd.rd”, sur lequel nous démarrerons pour mettre à jour : (je le récupère ici sur mon ftp favori, situé à Paris)

Contexte J'ai un PC plus ancien sous Ubuntu qui sert à mes enfants. Après plusieurs mises à jour du noyau, beaucoup d'installations de packages à l'essai, j'ai eu envie d'un grand nettoyage. Et au passage d'y installer un OpenBSD comme laboratoire de développement, serveur internet derrière ma Freebox.

The first paragraph of this book's afterword reads:

“ "You now know more about SSH, OpenSSH and Putty than the vast majority of IT professionals! Congratulations". ”

That claim will be true for any reader of SSH Mastery who has read the book up to that point and has incorporated at least some of the elements of the configurations it describes into their own environments.

Le langage forth sous Unix Le minimum vital à savoir Le langage forth, (ici gforth), est un langage de forte abstraction, un peu comme l'assembleur, mais sa simplicité et sa souplesse en font un langage très intéressant. Il n'a malheureusement pas eu le succès qu'il mérite. On le retrouve dans tout un tas de domaines + ou - connus, machines outils, l'ordinateur des années 80 le Micronique Hector HRX (ainsi que les modèles MX bien sur), dans la boot PROM des machine SunMicrosystems (sparcstatio…

Bonjour, voici un petit script que j'ai développé en réponse à la lenteur, à mon goût, de la commande “pkg_info -Q” pour la recherche de packages. Il suffit de l'exécuter directement en ”./packages” ou en le copiant dans /usr/local/bin/ et en lançant directement la commande packages.

In episode 208 of his bsdtalk podcast, Will Backman talks about how he uses OpenBSD virtual machines to aid in his teaching of a Unix course at the University of Maine, along with details of why he chose it and how it helps round-out his pupils' understanding of different Unixes.

The podcast files (15min, 7MB) are available here:

Daniel M wrote in about the wiconfig script that he wrote to handle moving a laptop between networks:

So, I got tired of doing my little time saving workarounds every time I connected to a wireless network and decided to look for a solution. Several people have posted little wireless scripts here, to misc@ and minor modifications to help simplify and automate the configuration of wireless, but the scripts never seemed to go far enough.
