QLC Plus

QLC+ is a free software to control DMX or analog lighting systems like moving heads, dimmers, scanners etc.

This project is a fork of the great QLC project written by Heikki Junnila that aims to continue the development of QLC and to introduce new features.

The primary goal is to bring QLC+ at the level of other lighting control commercial softwares.

Google’s fair use victory is good for open source

Let me first explain the main facts and claims in the lawsuit, and then why Google’s fair use victory is a good thing not only for Google but also for open source developers, for software developers more generally, and for the public.

So why is this a victory for the open source community as well as for Google? The main reason is because open source programs are often designed to interoperate with, either as complements or substitutes for, existing programs.

Hurst is wrong in asserting that Google’s fair use victory means that anyone can freely appropriate whatever they want from open source and other programs.

Be your own VPN provider with OpenBSD

We’ve covered how to build a BSD-based gateway that tunnels all your traffic through a VPN in the past – but what if you don’t trust any VPN company?
It’s easy for anyone to say “of course we don’t run a modified version of OpenVPN that logs all your traffic… what are you talking about?”
The VPN provider might also be slow to apply security patches, putting you and the rest of the users at risk
With this guide, you’ll be able to cut out the middleman and create your own VPN, using OpenBSD
It covers topics such as protecting your server, securing DNS lookups, configuring the firewall properly, general security practices and of course actually setting up the VPN

FreeBSD vs Gentoo comparison

People coming over from Linux will sometimes compare FreeBSD to Gentoo, mostly because of the ports-like portage system for installing software
This article takes that notion and goes much more in-depth, with lots more comparisons between the two systems
The author mentions that the installers are very different, ports and portage have many subtle differences and a few other things
If you’re a curious Gentoo user considering FreeBSD, this might be a good article to check out to learn a bit more

Kernel W^X in OpenBSD

W^X, “Write XOR Execute,” is a security feature of OpenBSD with a rather strange-looking name
It’s meant to be an exploit mitigation technique, disallowing pages in the address space of a process to be both writable and executable at the same time
This helps prevent some types of buffer overflows: code injected into it won’t execute, but will crash the program (quite obviously the lesser of the two evils)
Through some recent work, OpenBSD’s kernel now has no part of the address space without this feature – whereas it was only enabled in the userland previously
Doing this incorrectly in the kernel could lead to far worse consequences, and is a lot harder to debug, so this is a pretty huge accomplishment that’s been in the works for a while
More technical details can be found in some recent CVS commits

Building an IPFW-based router

We’ve covered building routers with PF many times before, but what about IPFW?
A certain host of a certain podcast decided it was finally time to replace his disappointing consumer router with something FreeBSD-based
In this blog post, Kris details his experience building and configuring a new router for his home, using IPFW as the firewall
He covers in-kernel NAT and NATD, installing a DHCP server from packages and even touches on NAT reflection a bit
If you’re an IPFW fan and are thinking about putting together a new router, give this post a read

News Roundup

On profiling HTTP

Adrian Chadd, who we’ve had on the show before, has been doing some more ultra-high performance testing
Faced with the problem of how to generate a massive amount of HTTP traffic, he looked into the current state of benchmarking tools
According to him, it’s “not very pretty”
He decided to work on a new tool to benchmark huge amounts of web traffic, and the rest of this post describes the whole process
You can check out his new code on Github right now

Using divert(4) to reduce attacks

We talked about using divert(4) with PF last week, and this post is a good follow-up to that introduction (though unrelated to that series)
It talks about how you can use divert, combined with some blacklists, to reduce attacks on whatever public services you’re running
PF has good built-in rate limiting for abusive IPs that hit rapidly, but when they attack slowly over a longer period of time, that won’t work
The Composite Blocking List is a public DNS blocklist, operated alongside Spamhaus, that contains many IPs known to be malicious
Consider setting this up to reduce the attack spam in your logs if you run public services

ChaCha20 patchset for GELI

A user has posted a patch to the freebsd-hackers list that adds ChaCha support to GELI, the disk encryption system
There are also some benchmarks that look pretty good in terms of performance
Currently, GELI defaults to AES in XTS mode with a few tweakable options (but also supports Blowfish, Camellia and Triple DES)
There’s some discussion going on about whether a stream cipher is suitable or not for disk encryption though, so this might not be a match made in heaven just yet

PCBSD update system enhancements

The PCBSD update utility has gotten an update itself, now supporting automatic upgrades
You can choose what parts of your system you want to let it automatically handle (packages, security updates)
There’s also a new graphical frontend available for it
The update system uses ZFS + Boot Environments for safe updating and bypasses some dubious pkgng functionality

Bitrig 1.0 released

If you haven’t heard of it, Bitrig is a fork of OpenBSD that started a couple years ago
According to their FAQ, some of their goals include: only supporting modern hardware and a limited set of CPU architectures, replacing nearly all GNU tools in base with BSD versions and having better virtualization support
They’ve finally announced their first official release, 1.0
This release introduces support for Clang 3.4, replacing the old GCC, along with libc++ replacing the GNU version
It also includes filesystem journaling, support for GPT and – most importantly – a hacker- style console with green text on black background
One of the developers answered some questions about it on Hacker News too

Is it time to try BSD?

Here we get a little peek into the Linux world – more and more people are considering switching
On a more mainstream tech news site, they have an article about people switching away from Linux and to BSD
People are starting to get even more suspicious of systemd, and lots of drama in the Linux world is leading a whole new group of potential users over to the BSD side
This article explores some pros and cons of switching, and features opinions of various users

Poudriere 3.1 released

One of the first things we ever covered on the show was poudriere, a tool with a funny name that’s used to build binary packages from FreeBSD ports
It’s come a long way since then, and bdrewery and bapt have just announced a new major version
This new release features a redesigned web interface to check on the status of your packages
There are lots of new bulk building options to preserve packages even if some fail to compile – this makes maintaining a production repo much easier
It also introduces a useful new “pkgclean” subcommand to clean out your repository of packages that aren’t needed anymore, and poudriere keeps it cleaner by default as well now
Check the full release notes for all the additions and bug fixes

Firewalling with OpenBSD’s pf and pfsync

A talk by David Gwynne from an Australian conference was uploaded, with the subject matter being pf and pfsync
He uses pf to manage 60 internal networks with a single firewall
The talk gives some background on how pf originally came to be and some OpenBSD 101 for the uninitiated
It also touches on different rulesets, use cases, configuration syntax, placing limits on connections, ospf, authpf, segregating VLANs, synproxy handling and a lot more
The second half of the presentation focuses on pfsync and carp for failover and redundancy
With two BSD boxes running pfsync, you can actually patch your kernel and still stay connected to IRC

News Roundup

Infrastructural enhancements at NYI

The FreeBSD foundation put up a new blog post detailing some hardware improvements they’ve recently done
Their eastern US colocation is hosted at New York Internet, and is used for FTP mirrors, pkgng mirrors, and also as a place for developers to test things
There’ve been fourteen machines purchased since July, and now FreeBSD boasts a total of sixty-eight physical boxes there
This blog post goes into detail about how those servers are used and details some of the network topology

The long tail of MD5

Our friend Ted Unangst is on a quest to replace all instances of MD5 in OpenBSD’s tree with something more modern
In this blog post, he goes through some of the different areas where MD5 still lives, and discovers how easy (or impossible) it would be to replace
Through some recent commits, OpenBSD now uses SHA512 in some places that you might not expect
Some other places require a bit more care…

DragonFly cheat sheet

If you’ve been thinking of trying out DragonFlyBSD lately, this might make the transition a bit easier
A user-created “cheat sheet” on the website lists some common answers to beginner questions
The page features a walkthrough of the installer, some shell tips and workarounds for various issues
At the end, it also has some things that new users can get involved with to help out

Experiences with an OpenBSD laptop

A lot of people seem to be interested in trying out some form of BSD on their laptop, and this article details just that
The author got interested in OpenBSD mostly because of the security focus and the fact that it’s not Linux
In this blog post, he goes through the steps of researching, installing, configuring, upgrading and finally actually using it on his Thinkpad
He even gives us a mention as a good place to learn more about BSD, thanks!

PC-BSD Updates

A call for testing of a new update system has gone out
Conversion to Qt5 for utils has taken place

Microsoft (hearts) Linux, for Azure’s sake

Microsoft now loves Linux.

This was the message from Microsoft CEO Satya Nadella, standing in front of an image that read “Microsoft [heart symbol] Linux,” during a Monday webcast to announce a number of services it had added to its Azure cloud, including the Cloudera Hadoop package and the CoreOS Linux distribution.

Microsoft has rolled out an astonishing 300 major new features and services in Azure in the last 12 months.
There are 10,000 new Azure customers per week.
There are currently 350 million Azure Active Directory users.
Over 2 million developers using Visual Studio Online.
Where once customers were using only basic Azure services, 60% are now using the higher level services.

and…

CoreOS support in Azure. Container-optimized Linux distribution with a minimal memory footprint is available starting today in the Azure Marketplace.

Lets Fork it!

Shall we fork Fedora?

Not really, it’s doing great. Maybe we’re not veteran enough?

Roll up your sleeves, we may need to fork Debian.

Note that the linked Debian Fork page specifically says that the anonymous developers behind it support a proposal to preserve options in init systems, rather than demanding the removal of systemd, and are not opposed to change per se. They just don’t want other parts of the system to be wholly dependent on systemd. “We contemplate adopting more recent alternatives to sysvinit, but not those undermining the basic design principles of “do one thing and do it well” with a complex collection of dozens of tightly coupled binaries and opaque logs.”

We\’re back again! On this week\’s packed show, we\’ve got one of the biggest tutorials we\’ve done in a while. It\’s an in-depth look at PF, OpenBSD\’s firewall, with some practical examples and different use cases.

We\’ll also be talking to Peter Hansteen about the new edition of \”The Book of PF.\” Of course, we\’ve got news and answers to your emails too, on BSD Now – the place to B.. SD.

Headlines

ALTQ removed from PF

The classic packet queueing system, ALTQ, was recently removed from OpenBSD -current
There will be a transitional phase between 5.5 and 5.6 where you can still use it by replacing the \”queue\” keyword with \”oldqueue\” in your pf.conf
As of 5.6, due about six months from now, you\’ll have to change your ruleset to the new syntax if you\’re using it for bandwidth shaping
After more than ten years, bandwidth queueing has matured quite a bit and we can finally put ALTQ to rest, in favor of the new queueing subsystem
This doesn\’t affect FreeBSD, PCBSD, NetBSD or DragonflyBSD since all of their PFs are older and maintained separately

FreeBSD Quarterly Status Report

The quarterly status report from FreeBSD is out, detailing some of the project\’s ongoing tasks
Some highlights include the first \”stable\” branch of ports, ARM improvements (including SMP), bhyve improvements, more work on the test suite, desktop improvements including the new vt console driver and UEFI booting support finally being added
We\’ve got some specific updates from the cluster admin team, core team, documentation team, portmgr team, email team and release engineering team
LOTS of details and LOTS of topics to cover, give it a read

OpenBSD\’s OpenSSL rewrite continues with m2k14

A mini OpenBSD hackathon begins in Morocco, Africa
You can follow the changes in the -current CVS log, but a lot of work is mainly going towards the OpenSSL cleaning
We\’ve got two trip reports so far, hopefully we\’ll have some more to show you in a future episode
You can see some of the more interesting quotes from the tear-down or see everything
Apparently they are going to call the fork \”LibreSSL\” ….
What were the OpenSSL developers thinking? The RSA private key was used to seed the entropy!
We also got some mainstream news coverage and another post from Ted about the history of the fork
OpenBSD developer Reyk Floeter implemented privilege separation to store RSA keys in a separate process as an additional mitigation against key leakage from attacks such as heartbleed in relayd and OpenSMTPD
You can compile libressl for other OSes
Consider donating to the OpenBSD foundation – this fork will benefit all the other BSDs too

NetBSD 6.1.4 and 6.0.5 released

New updates for the 6.1 and 6.0 branches of NetBSD, focusing on bugfixes
The main update is – of course – the heartbleed vulnerability
Also includes fixes for other security issues and even a kernel panic… on Atari
Patch your Ataris right now, this is serious business

News Roundup

New Xorg now the default in FreeBSD

For quite a while now, FreeBSD has had two versions of X11 in ports
The older, stable version was the default, but you could install a newer one by having \”WITH_NEW_XORG\” in /etc/make.conf
They\’ve finally made the switch for 10-STABLE and 9-STABLE
Check this wiki page for more info

GSoC-accepted BSD projects

The Google Summer of Code team has got the list of accepted project proposals uploaded so we can see what\’s planned
OpenBSD\’s list includes DHCP configuration parsing improvements, systemd replacements, porting capsicum, GPT and UEFI support, and modernizing the DHCP daemon
The FreeBSD list was also posted
Theirs includes porting FreeBSD to the Android emulator, CTF in the kernel debugger, improved unicode support, converting firewall rules to a C module, pkgng improvements, MicroBlaze support, PXE fixes, bhyve caching, bootsplash and lots more
Good luck to all the students participating, hopefully they become full time BSD users

Complexity of FreeBSD VFS using ZFS as an example

HybridCluster posted the second part of their VFS and ZFS series
This new post has lots of technical details once again, definitely worth reading if you\’re a ZFS guy
Of course, also watch episode 24 for our interview with HybridCluster – they do really interesting stuff

PCBSD weekly digest

Preload has been ported over, it\’s a daemon that prefetches applications
PCBSD is developing their own desktop environment, Lumina (there\’s also an FAQ)
It\’s still in active development, but you can try it out by installing from ports
We\’ll be showing a live demo of it in a few weeks (when development settles down a bit)

All the tutorials are posted in their entirety at bsdnow.tv
Send questions, comments, show ideas/topics, or stories you want mentioned on the show to feedback@bsdnow.tv
If you\’ve got something cool to talk about and want to come on for an interview, shoot us an email
Also if you have any tutorial requests, we\’d be glad to show whatever the viewers want to see
It looks like OpenBSD 5.5 CD sets are already starting to show up in people\’s mail boxes – we\’ll have the full details of the release next week

Blink a new fork of Webkit announced by Google looks to reignite the age old browser war, but this time around Mike and Chris think it’s only going to hurt developers, support personnel, and end users.

Plus the return of a notorious patent troll, and you won’t believe what they are claiming this time. Betting on the OUYA, a big batch of your emails, and much more!
