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.

wiconfig - simplifies the configuration of wireless interfaces
Contributed by sean on Fri Jan 13 17:09:22 2012 (GMT)
from the airborne packets dept.

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.

A Week of OpenBSD Hacking In Slovenia: Developers Report From s2k11 (Part 3)
Contributed by pitrh on Fri Nov 4 10:09:22 2011 (GMT)
from the roomful of puffies dept.

s2k11 T-shirt design For a few days in September (16th through 23rd), the Slovenian capital Ljubljana was also the World Capital of OpenBSD hacking, hosting the s2k11: General hackathon, with 25 developers participating. We asked each of the the developers to send us a short summary of what happened at s2k11 as soon as they'd caught up on sleep, and several of them obliged quickly.

We published a small selection in Part 1 and Part 2 of this series, here we present the third and final installment, with insights into the development process and previews of features that may soon appear in -current and snapshots before they make it into an upcoming release.

Slovenian interview with Theo
Contributed by mitja on Tue Oct 18 06:00:00 2011 (GMT)
from the babelfish-is-out-swimming dept.

The main Slovenian daily newspaper Delo has published their interview with Theo which they did during s2k11. For those Undeadly readers that do not understand Slovenian, we've approached Delo to ask them for permission to translate and publish their article. Even though the interview was targeted at general public, it offers a valuable insight on some less technical aspects of OpenBSD.
