The Story Of The Extra Audio Track: Recording Music With OpenBSD
Contributed by weerd on Sat Mar 31 14:40:01 2012 (GMT)
from the Puffy Burst Into Song dept.

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.

It's Official: OpenBSD Helps Me Do Better Science
Contributed by jj on Fri Mar 23 07:58:41 2012 (GMT)
from the sudo-make-me-coffee-in-parallel dept.

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!

from the bugs-be-gone dept.

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 
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.

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

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!

SI6 Networks: OpenBSD Well Ahead Of The Pack In IPv6 Fragment Handling Sanity (and RFC compliance)
Contributed by pitrh on Tue Feb 21 14:09:10 2012 (GMT)
from the they weren't supposed to exist dept.

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.

Read the full article over at the SI6 site: IPv6 NIDS evasion and improvements in IPv6 fragmentation/reassembly

SSH Mastery pre-orders now available, to benefit OpenBSD
Contributed by weerd on Sat Feb 18 08:51:26 2012 (GMT)
from the plant-a-tree dept.

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 for details

SSH Mastery: A Very Welcome Addition to Any Unix User's Bookshelf
Contributed by pitrh on Sun Jan 22 18:18:22 2012 (GMT)
from the crypted intartubes dept.

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.
