FreeBSD foundation\’s 2013 fundraising results

The FreeBSD foundation finally counted all the money they made in 2013
$768,562 from 1659 donors
Nice little blog post from the team with a giant beastie picture
\”We have already started our 2014 fundraising efforts. As of the end of January we are just under $40,000. Our goal is to raise $1,000,000. We are currently finalizing our 2014 budget. We plan to publish both our 2013 financial report and our 2014 budget soon.\”
A special thanks to all the BSD Now listeners that contributed, the foundation was really glad that we sent some people their way (and they mentioned us on Facebook)

OpenSSH 6.5 released

We mentioned the CFT last week, and it\’s finally here!
New key exchange using elliptic-curve Diffie Hellman in Daniel Bernstein\’s Curve25519 (now the default when both clients support it)
Ed25519 public keys are now available for host keys and user keys, considered more secure than DSA and ECDSA
Funny side effect: if you ONLY enable ed25519 host keys, all the compromised Linux boxes can\’t even attempt to login
New bcrypt private key type, 500,000,000 times harder to brute force
Chacha20-poly1305 transport cipher that builds an encrypted and authenticated stream in one
Portable version already in FreeBSD -CURRENT, and ports
Lots more bugfixes and features, see the full release note or our interview with Damien
Work has already started on 6.6, which can be used without OpenSSL!

Crazed Ferrets in a Berkeley Shower

In 2000, MWL wrote an essay for linux.com about why he uses the BSD license: \”It’s actually stood up fairly well to the test of time, but it’s fourteen years old now.\”
This is basically an updated version about why he uses the BSD license, in response to recent idiocy from Richard Stallman
Very nice post that gives some history about Berkeley, the basics of the BSD-style licenses and their contrast to the GNU GPL
Check out the full post if you\’re one of those people that gets into license arguments
The takeaway is \”BSD is about making the world a better place. For everyone.\”

OpenBSD on BeagleBone Black

Beaglebone Blacks are cheap little ARM devices similar to a Raspberry Pi
A blog post about installing OpenBSD on a BBB from.. our guest for today!
He describes it as \”everything I wish I knew before installing the newly renamed armv7 port on a BeagleBone Black\”
It goes through the whole process, details different storage options and some workarounds
Could be a really fun weekend project if you\’re interested in small or embedded devices

Secure communications with OpenBSD and OpenVPN

Starting off today\’s theme of encryption…
A new blog series about combining OpenBSD and OpenVPN to secure your internet traffic
Part 1 covers installing OpenBSD with full disk encryption (which we\’ll be doing later on in the show)
Part 2 covers the initial setup of OpenVPN certificates and keys
Parts 3 and 4 are the OpenVPN server and client configuration
Part 5 is some updates and closing remarks

FreeBSD Foundation Newsletter

The December 2013 semi-annual newsletter was sent out from the foundation
In the newsletter you will find the president\’s letter, articles on the current development projects they sponsor and reports from all the conferences and summits they sponsored
The president\’s letter alone is worth the read, really amazing
Really long, with lots of details and stories from the conferences and projects

Use of NetBSD with Marvell Kirkwood Processors

Article that gives a brief history of NetBSD and how to use it on an IP-Plug computer
The IP-Plug is a \”multi-functional mini-server was developed by Promwad engineers by the order of AK-Systems. It is designed for solving a wide range of tasks in IP networks and can perform the functions of a computer or a server. The IP-Plug is powered from a 220V network and has low power consumption, as well as a small size (which can be compared to the size of a mobile phone charger).\”
Really cool little NetBSD ARM project with lots of graphs, pictures and details

Experimenting with zero-copy network IO

Long blog post from Adrian Chad about zero-copy network IO on FreeBSD
Discusses the different OS\’ implementations and options
He\’s able to get 35 gbit/sec out of 70,000 active TCP sockets, but isn\’t stopping there
Tons of details, check the full post

News Roundup

OpenZFS office hours

Our buddy George Wilson sat down to take some ZFS questions from the community
You can see more info about it here

License summaries in pkgng

A discussion between Justin Sherill and some NYCBUG guys about license frameworks in pkgng
Similar to pkgsrc\’s \”ACCEPTABLE_LICENSES\” setting, pkgng could let the user decide which software licenses he wants to allow
Maybe we could get a \”pkg licenses\” command to display the license of all installed packages
Ok bapt, do it

pkgng 1.2 released

bapt and bdrewery from the portmgr team released pkgng 1.2 final
New features include an improved build system, plugin improvements, new bootstrapping command, SRV mirror improvements, a new \”pkg config\” command, repo improvements, vuXML is now default, new fingerprint features and much more
Really simple to upgrade, check our pkgng tutorial if you want some easy instructions
It\’s also made its way into Dragonfly
See the show notes for the full list of new features and fixes

ChaCha20 and Poly1305 in OpenSSH

Damien Miller recently committed support for a new authenticated encryption cipher for OpenSSH, chacha20-poly1305
Long blog post explaining what these are and why we need them
This cipher combines two primitives: the ChaCha20 cipher and the Poly1305 MAC
RC4 is broken, we needed an authenticated encryption mode to complement AES-GCM that doesn\’t show the packet length in cleartext
Great explanation of the differences between EtM, MtE and EaM and their advantages
\”Both AES-GCM and the EtM MAC modes have a small downside though: because we no longer desire to decrypt the packet as we go, the packet length must be transmitted in plaintext. This unfortunately makes some forms of traffic analysis easier as the attacker can just read the packet lengths directly.\”

Is it time to dump Linux and move to BSD

ITworld did an article about switching from Linux to BSD
The author\’s interest was sparked from a review he was reading that said \”I feel the BSD communities, especially the FreeBSD-based projects, are where the interesting developments are happening these days. Over in FreeBSD land we have efficient PBI bundles, a mature advanced file system in the form of ZFS, new friendly and powerful system installers, a new package manager (pkgng), a powerful jail manager and there will soon be new virtualization technology coming with the release of FreeBSD 10.0\”
The whole article can be summed up with \”yes\” – ok, next story!

OpenZFS devsummit videos

Kicking off the ZFS episode, we\’ve got…
The OpenZFS developer summit discussion and presentation videos are up
People from various operating systems (FreeBSD, Mac OS X, illumos, etc.) were there to discuss ZFS on their platforms and the challenges they faced
Question and answer session from representatives of every OS – had a couple FreeBSD guys there including one from the foundation
Presentations both about ZFS itself and some hardware-based solutions for implementing ZFS in production
TONS of video, about 6 hours\’ worth
This leads us into our interview, which is…

Interview – George Wilson – Soft Eng at Delphix – wilzun@gmail.com / @zfsdude

KM: Can you tell us a little about yourself how you first got involved with ZFS?
AJ: Which features have you worked on in the past?
KM: Which platform do you personally use ZFS on, and for what tasks?
AJ: So what exactly is the OpenZFS project about?
KM: What do you hope the future of OpenZFS will bring?
AJ: When are we going to see native encryption?
KM: Are there some new features you\’re currently hacking on?
AJ: Is there anything specific you\’d like to see added to ZFS in the future?
KM: How did the developer summit and hackathon go?
AJ: Where can people go to get involved with development, and what\’s currently needed?
KM: Anything else you\’d like to mention?
