pfSense 2.1.4 released

The pfSense team has released 2.1.4, shortly after 2.1.3 – it’s mainly a security release
Included within are eight security fixes, most of which are pfSense-specific
OpenSSL, the WebUI and some packages all need to be patched (and there are instructions on how to do so)
It also includes a large number of various other bug fixes
Update all your routers!

DragonflyBSD’s pf gets SMP

While we’re on the topic of pf…
Dragonfly patches their old[er than even FreeBSD’s] pf to support multithreading in many areas
Stemming from a user’s complaint, Matthew Dillon did his own work on pf to make it SMP-aware
Altering your configuration‘s ruleset can also help speed things up, he found
When will OpenBSD, the source of pf, finally do the same?

ChaCha usage and deployment

A while back, we talked to djm about some cryptography changes in OpenBSD 5.5 and OpenSSH 6.5
This article is sort of an interesting follow-up to that, showing which projects have adopted ChaCha20
OpenSSH offers it as a stream cipher now, OpenBSD uses it for it’s random number generator, Google offers it in TLS for Chromium and some of their services and lots of other projects seem to be adopting it
Both Google’s fork of OpenSSL and LibReSSL have upcoming implementations, while vanilla OpenSSL does not
Unfortunately, this article has one mistake: FreeBSD does not use it – they still use the broken RC4 algorithm

BSDMag June 2014 issue

The monthly online BSD magazine releases their newest issue
This one includes the following articles: TLS hardening, setting up a package cluster in MidnightBSD, more GIMP tutorials, “saving time and headaches using the robot framework for testing,” an interview and an article about the increasing number of security vulnerabilities
The free pdf file is available for download as always

Interview – Craig Rodrigues – rodrigc@freebsd.org

FreeBSD’s continuous testing infrastructure

Tutorial

Creating pre-patched OpenBSD ISOs

News Roundup

Preauthenticated decryption considered harmful

Responding to a post from Adam Langley, Ted Unangst talks a little more about how signify and pkg_add handle signatures
In the past, the OpenBSD installer would pipe the output of ftp straight to tar, but then verify the SHA256 at the end – this had the advantage of not requiring any extra disk space, but raised some security concerns
With signify, now everything is fully downloaded and verified before tar is even invoked
The pkg_add utility works a little bit differently, but it’s also been improved in this area – details in the post
Be sure to also read the original post from Adam, lots of good information

FreeBSD 9.3-RC2 is out

As the -RELEASE inches closer, release candidate 2 is out and ready for testing
Since the last one, it’s got some fixes for NIC drivers, the latest file and libmagic security fixes, some serial port workarounds and various other small things
The updated bsdconfig will use pkgng style packages now too
A lesser known fact: there are also premade virtual machine images you can use too

pkgsrcCon 2014 wrap-up

In what may be the first real pkgsrcCon article we’ve ever had!
Includes wrap-up discussion about the event, the talks, the speakers themselves, what they use pkgsrc for, the hackathon and basically the whole event
Unfortunately no recordings to be found…

PostgreSQL FreeBSD performance and scalability

FreeBSD developer kib@ writes a report on PostgreSQL on FreeBSD, and how it scales
On his monster 40-core box with 1TB of RAM, he runs lots of benchmarks and posts the findings
Lots of technical details if you’re interested in getting the best performance out of your hardware
It also includes specific kernel options he used and the rest of the configuration
If you don’t want to open the pdf file, you can use this link too

Feedback/Questions

All the tutorials are posted in their entirety at bsdnow.tv
There, you’ll also find a link to Bob Beck’s LibReSSL talk from the end of May – we finally found a recording!

EuroBSDCon 2014 talks and schedule

The talks and schedules for EuroBSDCon 2014 are finally revealed
The opening keynote is called “FreeBSD, looking forward to another 10 years” by jkh
Lots of talks spanning FreeBSD, OpenBSD and PCBSD, and we finally have a few about NetBSD and DragonflyBSD too! Variety is great
It looks like Theo even has a talk, but the title isn’t on the page… how mysterious
There are also days dedicated to some really interesting tutorials
Register now, the conference is on September 25-28th in Bulgaria
If you see Allan and Kris walking towards you and you haven’t given us an interview yet… well you know what’s going to happen
Why aren’t the videos up from last year yet? Will this year also not have any?

FreeNAS vs NAS4Free

More mainstream news covering BSD, this time with an article about different NAS solutions
In a possibly excessive eight-page article, Ars Technica discusses the pros and cons of both FreeNAS and NAS4Free
Both are based on FreeBSD and ZFS of course, but there are more differences than you might expect
Discusses the different development models, release cycles, features, interfaces and ease-of-use factor of each project
“One is pleasantly functional; the other continues devolving during a journey of pain” – uh oh, who’s the loser?

Quality software costs money, heartbleed was free

PHK writes an article for ACM Queue about open source software projects’ funding efforts
A lot of people don’t realize just how widespread open source software is – TVs, printers, gaming consoles, etc
The article discusses ways to convince your workplace to fund open source efforts, then goes into a little bit about FreeBSD and Varnish’s funding
The latest heartbleed vulnerability should teach everyone that open source projects are critical to the internet, and need people actively maintaining them
On that subject, “Earlier this year the OpenSSL Heartbleed bug laid waste to Internet security, and there are still hundreds of thousands of embedded devices of all kinds—probably your television among them—that have not been and will not ever be software-upgraded to fix it. The best way to prevent that from happening again is to avoid having bugs of that kind go undiscovered for several years, and the only way to avoid that is to have competent people paying attention to the software”
Consider donating to your favorite BSD foundation (or buying cool shirts and CDs!) and keeping the ecosystem alive

Geoblock evasion with pf and OpenBSD rdomains

Geoblocking is a way for websites to block visitors based on the location of their IP
This is a blog post about how to get around it, using pf and rdomains
It has the advantage of not requiring any browser plugins or DNS settings on the users’ computers, you just need to be running OpenBSD on your router (hmm, if only a website had a tutorial about that…)
In this post, the author wanted to get an American IP address, since the service he was using (Netflix) is blocked in Australia
It’s got all the details you need to set up a VPN-like system and bypass those pesky geographic filters

Interview – Marc Espie – espie@openbsd.org / @espie_openbsd

OpenBSD’s package system, building cluster, various topics

Keeping your BSD up to date

News Roundup

BoringSSL and LibReSSL

Yet another OpenSSL fork pops up, this time from Google, called BoringSSL
Adam Langley has a blog post about it, why they did it and how they’re going to maintain it
You can easily browse the source code
Theo de Raadt also weighs in with how this effort relates to LibReSSL
More eyes on the code is good, and patches will be shared between the two projects

More BSD Tor nodes wanted

Friend of the show bcallah posts some news to the Tor-BSD mailing list about monoculture in the Tor network being both bad and dangerous
Originally discussed on the Tor-Relays list, it was made apparent that having such a large amount of Linux nodes weakens the security of the whole network
If one vulnerability is found, a huge portion of the network would be useless – we need more variety in the network stacks, crypto, etc.
The EFF is also holding a Tor challenge for people to start up new relays and keep them online for over a year
Check out our Tor tutorial and help out the network, and promote BSD at the same time!

FreeBSD 10 OpenStack images

OpenStack, to quote Wikipedia, is “a free and open-source software cloud computing platform. It is primarily deployed as an infrastructure as a service (IaaS) solution.”
The article goes into detail about creating a FreeBSD instant, installing and converting it for use with “bsd-cloudinit”
The author of the article is a regular listener and emailer of the show, hey!

BSDday 2014 call for papers

BSD Day, a conference not so well-known, is going to be held August 9th in Argentina
It was created in 2008 and is the only BSD conference around that area
The “call for papers” was issued, so if you’re around Argentina and use BSD, consider submitting a talk
Sysadmins, developers and regular users are, of course, all welcome to come to the event

FreeBSD 10 as a firewall

Back in 2012, the author of this site wrote an article stating you should avoid FreeBSD 9 for a firewall and use OpenBSD instead
Now, with the release of 10.0, he\’s apparently changed his mind and switched back over
It mentions the SMP version of pf, general performance advantages and more modern features
The author is a regular listener of BSD Now, hi Joe!

Network Noise Reduction Using Free Tools

Really long blog post, based on a BSDCan presentation, about fighting spam with OpenBSD
Peter Hansteen, author of the book of PF, goes through how he uses OpenBSD\’s spamd and other security features to combat spam and malware
He goes through his experiences with content filtering and disappointment with a certain proprietary vendor
Not totally BSD-specific, lots of people can enjoy the article – lots of virus history as well

FreeBSD ASLR patches submitted

So far, FreeBSD hasn\’t had Address Space Layout Randomization
ASLR is a nice security feature, see wikipedia for more information
With a giant patch from Shawn Webb, it might be integrated into a future version (after a vicious review from the security team of course)
We might have Shawn on the show to talk about it, but he\’s also giving a presentation at BSDCan about his work with ASLR

Old-style pkg_ tools retired

At last the old pkg_add tools are being retired in FreeBSD
pkgng is a huge improvement, and now portmgr@ thinks it\’s time to cut the cord on the legacy toolset
Ports aren\’t going away, and probably never will, but for binary package fans and new users that are used to things like apt, pkgng is the way to go
All pkg_ tools will be considered unsupported on September 1, 2014 – even on older branches

News Roundup

FreeBSD on OpenStack

OpenStack is a cloud computing project
It consists of \”a series of interrelated projects that control pools of processing, storage, and networking resources throughout a datacenter, able to be managed or provisioned through a web-based dashboard, command-line tools, or a RESTful API.\”
Until now, there wasn\’t a good way to run a full BSD instance on OpenStack
With a project in the vein of Colin Percival\’s AWS startup scripts, now that\’s no longer the case!

FOSDEM BSD videos

This year\’s FOSDEM had seven BSD presentations
The videos are slowly being uploaded for your viewing pleasure
Not all of the BSD ones are up yet, but by the time you\’re watching this they might be!
Check this directory for most of \’em
The BSD dev room was full, lots of interest in what\’s going on from the other communities

The FreeBSD challenge finally returns!

Due to prodding from a certain guy of a certain podcast, the \”FreeBSD Challenge\” series has finally resumed
Our friend from the Linux foundation picks up with day 11 and day 12 on his switching from Linux journey
This time he outlines the upgrade process of going from 9 to 10, using freebsd-update
There\’s also some notes about different options for upgrading ports and some extra tips

PCBSD weekly digest

After the big 10.0 release, the PCBSD crew is focusing on bug fixes for a while
During their \”fine tuning phase\” users are encouraged to submit any and all bugs via the trac system
Warden got some fixes and the package manager got some updates as well
Huge size reduction in PBI format

Faces of FreeBSD continues

Our first one details Shteryana Shopova, the local organizer for EuroBSDCon 2014 in Sophia
Gives some information about how she got into BSD
\”I installed FreeBSD on my laptop, alongside the Windows and Slackware Linux I was running on it at the time. Several months later I realized that apart from FreeBSD, I hadn\’t booted the other two operating systems in months. So I wiped them out.\”
She wrote bsnmpd and extended it with the help of a grant from the FreeBSD Foundation
We\’ve also got one for Kevin Martin
Started off with a pinball website, ended up learning about FreeBSD from an ISP and starting his own hosting company
\”FreeBSD has been an asset to our operations, and while we have branched out a bit, we still primarily use FreeBSD and promote it whenever possible. FreeBSD is a terrific technology with a terrific community.\”

OpenPF?

A blog post over at the Dragonfly digest
What if we had some cross platform development of OpenBSD\’s firewall?
Similar to portable OpenSSH or OpenZFS, there could be a centrally-developed version with compatibility glue
Right now FreeBSD 9\’s pf is old, FreeBSD 10\’s pf is old (but has the best performance of any implementation due to custom patches), NetBSD\’s pf is old (but they\’re working on a fork) and Dragonfly\’s pf is old
Further complicated by the fact that PF itself doesn’t have a version number, since it was designed to just be ‘the pf that came with OpenBSD 5.4’
Not likely to happen any time soon, but it\’s good food for thought

Year of BSD on the server

A good blog post about switching servers from Linux to BSD
2014 is going to be the year of a lot of switching, due to FreeBSD 10\’s amazing new features
This author was particularly taken with pkgng and the more coherent layout of BSD systems
Similarly, there was also a recent reddit thread, \”Why did you choose BSD over Linux?\”
Both are excellent reads for Linux users that are thinking about making the switch, send \’em to your friends

Getting to know your portmgr

This time in the series they interview Bryan Drewery, a fairly new addition to the team
He started maintaining portupgrade and portmaster, and eventually ended up on the ports management team
Believe it or not, his wife actually had a lot to do with him getting into FreeBSD full-time
Lots of fun trivia and background about him
Speaking of portmgr, our interview for today is…

pfSense 2.1-RELEASE is out

Now based on FreeBSD 8.3
Lots of IPv6 features added
Security updates, bug fixes, driver updates
PBI package support
Way too many updates to list, see the full list

New kernel based iSCSI stack comes to FreeBSD

Brief explanation of iSCSI
This work replaces the older userland iscsi target daemon and improves the in-kernel iscsi initiator
Target layer consists of:
ctld(8), a userspace daemon responsible for handling configuration, listening for incoming connections, etc, then handing off connections to the kernel after the iSCSI Login phase
iSCSI frontend to CAM Target Layer, which handles Full Feature phase.
The work is being sponsored by FreeBSD Foundation

MTier creates openup utility for OpenBSD

MTier provides a number of things for the OpenBSD community
For example, regularly updated (for security) stable packages from their custom repo
openup is a utility to easily check for security updates in both base and packages
It uses the regular pkg tools, nothing custom-made
Can be run from cron, but only emails the admin instead of automatically updating

OpenSSH in FreeBSD -CURRENT supports DNSSEC

OpenSSH in base is now compiled with DNSSEC support
In this case the default setting for ‘VerifyHostKeyDNS’ is yes
OpenSSH will silently trust DNSSEC-signed SSHFP records
It is the secteam’s opinion that this is better than teaching users to blindly hit “yes” each time they encounter a new key

Interview – Gilles Chehade & Eric Faurot – gilles@openbsd.org / @poolpOrg & eric@openbsd.org

OpenSMTPD

Q: Could you tell us a little bit about yourselves and how you got involved with OpenBSD?
Q: What exactly is OpenSMTPD and why was it created?
Q: How big is your team of developers? Who’s doing what?
Q: How compatible is it with things like dovecot, spamassassin, etc?
Q: Are there any advantages over the other mail servers like Postfix or Exim?
Q: If someone wanted to switch from them, is it an easy replacement?
Q: The config syntax is very nice and easy to grasp. Was inspired from PF’s at all?
Q: What made you decide to develop a portable version, a la OpenSSH?
Q: Tell us some cool, upcoming features in a future release
Q: Anything else you’d like to mention about the project?
Q: Where can people find more info and help with development if they want?

Tutorial

Using pkgng for binary package management

Live demo
pkgng is the replacement for the old pkg_add tools
Much more modern, supports an array of features that the old system didn’t
Works on DragonflyBSD as well

News Roundup

New progress with Newcons

Newcons is a replacement console driver for FreeBSD
