FreeBSD USB Audio

I recently got a Behringer UMC22 sound card for video conferencing and DJing. This page documents what I’ve learned about using this sound card, and USB audio in general, on FreeBSD.
tl;dr: Everything works as long as the sound card follows the USB audio device class specification.

Kyua: An introduction for NetBSD users

Kyua's current goal is to reimplement only the ATF tools while maintaining backwards compatibility with the tests written with the ATF libraries (i.e. with the NetBSD test suite).
Because Kyua is a replacement of some ATF components, the end goal is to integrate Kyua into the NetBSD base system (just as ATF is) and remove the deprecated ATF components. Removing the deprecated components will allow us to make the above-mentioned improvements to Kyua, as well as many others, without having to deal with the obsolete ATF code base. Discussing how and when this transition might happen is out of the scope of this document at the moment.

Keeping backup ZFS on Linux kernel modules around

I'm a long term user of ZFS on Linux and over pretty much all of the time I've used it, I've built it from the latest development version. Generally this means I update my ZoL build at the same time as I update my Fedora kernel, since a ZoL update requires a kernel reboot anyway. This is a little bit daring, of course, although the ZoL development version has generally been quite solid (and this way I get the latest features and improvements long before I otherwise would).

Command-line Tools can be 235x Faster than your Hadoop Cluster

As I was browsing the web and catching up on some sites I visit periodically, I found a cool article from Tom Hayden about using Amazon Elastic Map Reduce (EMR) and mrjob in order to compute some statistics on win/loss ratios for chess games he downloaded from the millionbase archive, and generally have fun with EMR. Since the data volume was only about 1.75GB containing around 2 million chess games, I was skeptical of using Hadoop for the task, but I can understand his goal of learning and having fun with mrjob and EMR. Since the problem is basically just to look at the result lines of each file and aggregate the different results, it seems ideally suited to stream processing with shell commands. I tried this out, and for the same amount of data I was able to use my laptop to get the results in about 12 seconds (processing speed of about 270MB/sec), while the Hadoop processing took about 26 minutes (processing speed of about 1.14MB/sec).

FreeBSD Laptop Find Out Battery Life Status Command

I know how to find out battery life status using Linux operating system. How do I monitor battery status on a laptop running FreeBSD version 9.x/10.x/11.x/12.x?
You can use any one of the following commands to get battery status under FreeBSD laptop including remaining battery life and more.

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 ***

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 ***

BSDCan 2014 talks and reports, part 2

• More presentations and trip reports are still being uploaded
• Ingo Schwarze, New Trends in mandoc
• Vsevolod Stakhov, The Architecture of the New Solver in pkg
• Julio Merino, The FreeBSD Test Suite
• Zbigniew Bodek, Transparent Superpages for FreeBSD on ARM
• There's also a trip report from Michael Dexter and another (very long and detailed) trip report from our friend Warren Block that even gives us some linkage, thanks! ***

Beyond security, getting to know OpenBSD's real purpose

• Michael W Lucas (who, we learn through this video, has been using BSD since 1986) gave a "webcast" last week, and the audio and slides are finally up
• It clocks in at just over 30 minutes, managing to touch on a lot of OpenBSD topics
• Some of those topics include: what is OpenBSD and why you should care, the philosophy of the project, how it serves as a "pressure cooker for ideas," briefly touches on GPL vs BSDL, their "do it right or don't do it at all" attitude, their stance on NDAs and blobs, recent LibreSSL development, some of the security functions that OpenBSD enabled before anyone else (and the ripple effect that had) and, of course, their disturbing preference for comic sans
• Here's a direct link to the slides
• Great presentation if you'd like to learn a bit about OpenBSD, but also contains a bit of information that long-time users might not know too ***

FreeBSD vs Linux, a comprehensive comparison

• Another blog post covering something people seem to be obsessed with - FreeBSD vs Linux
• This one was worth mentioning because it's very thorough in regards to how things are done behind the scenes, not just the usual technical differences
• It highlights the concept of a "core team" and their role vs "contributors" and "committers" (similar to a presentation Kirk McKusick did not long ago)
• While a lot of things will be the same on both platforms, you might still be asking "which one is right for me?" - this article weighs in with some points for both sides and different use cases
• Pretty well-written and unbiased article that also mentions areas where Linux might be better, so don't hate us for linking it ***

Expand FreeNAS with plugins

• One of the things people love the most about FreeNAS (other than ZFS) is their cool plugin framework
• With these plugins, you can greatly expand the feature set of your NAS via third party programs
• This page talks about a few of the more popular ones and how they can be used to improve your NAS or media box experience
• Some examples include setting up an OwnCloud server, Bacula for backups, Maraschino for managing a home theater PC, Plex Media Server for an easy to use video experience and a few more
• It then goes into more detail about each of them, how to actually install plugins and then how to set them up ***

Code review culture meets FreeBSD

• In most of the BSDs, changes need to be reviewed by more than one person before being committed to the tree
• This article describes Phabricator, an open source code review system that we briefly mentioned last week
• Instructions for using it are on the wiki
• While not approved by the core team yet for anything official, it's in a testing phase and developers are encouraged to try it out and get their patches reviewed
• Just look at that fancy interface!! ***

Upcoming BSD books

• Sneaky MWL somehow finds his way into both our headlines and the news roundup
• He gives us an update on the next BSD books that he's planning to release
• The plan is to release three (or so) books based on different aspects of FreeBSD's storage system(s) - GEOM, UFS, ZFS, etc.
• This has the advantage of only requiring you to buy the one(s) you're specifically interested in
• "When will they be released? When I'm done writing them. How much will they cost? Dunno."
• It's not Absolute FreeBSD 3rd edition... ***

CARP failover and high availability on FreeBSD

• If you're running a cluster or a group of servers, you should have some sort of failover in place
• But the question comes up, "how do you load balance the load balancers!?"
• This video goes through the process of giving more than one machine the same IP, how to set up CARP, securing it and demonstrates a node dying
• Also mentions DNS-based load balancing as another option ***

PCBSD weekly digest

• This time in PCBSD land, we're getting ready for the 10.0.2 release (ISOs here)
• AppCafe got a good number of fixes, and now shows 10 random highlighted applications
• EasyPBI added a "bulk" mode to create PBIs of an entire FreeBSD port category
• Lumina, the new desktop environment, is still being worked on and got some bug fixes too ***
