This is another week where I find neat stuff at the start of the week, start the post, and by the time the post date rolls around, those links have been seen everywhere. Yes, I’m complaining I don’t get “First Post!” the way I want.
Your unrelated comics link of the week: Heads or Tails. Chris Ware’s comics are all about using the comic as a way of expressing the movement of time, in so many ways. (via)
I’ve got “coverage” of most every BSD this week.
As you can guess from the title, this week’s BSDNow talks about building OpenBSD packages in bulk among other things, and also interviews Jim Brown of bsdcertification.org.
The March issue of BSD Magazine is out, and this month has an article written by Siju George about how his company is using DragonFly and Hammer for backups.
Remember: If you have a particular port that’s not building in DragonFly, there may be a patch in pkgsrc that could be brought over, as John Marino points out.
Here’s the announcement from Francois Tigeot: DragonFly now uses dynamic binaries in the root filesystem. You will need to do a full buildworld/buildkernel if on 3.7 and upgrading.
I am all over the map this week.
Your unrelated animated image of the week: a seal with hiccups.
Some out-of-the-ordinary things this week.
DragonFly now has a ‘rescue’ system added in, which also functions as a way to mount encrypted filesystems. Does PAM work yet? I don’t know; I may be linking to this earlier than I need to.
I should have seen that pun coming a long time ago. BSDNow 032 is up with an interview of Dru Lavigne and the usual assortment of other recent BSD items.
Release 3.6.2 of DragonFly has been tagged, and ISO/img files are available. This includes an updated OpenSSL for Heartbleed problems. Here’s the changelog. You can, if you haven’t already, update your existing 3.6 systems the normal way.
All the dragonflybsd.org sites (www, bugs, gitweb, lists, leaf) should be available via https now, thanks to a wildcard certificate from InterNetX. Also, all the machines have an up-to-date version (1.0.1g) of OpenSSL installed to prevent the Heartbleed issue.
I’ve wanted more support for virtualized DragonFly systems. Sascha Wildner put together an experimental balloon memory driver to test out, and I ran it on two virtual machines separately, one with it loaded and one without, on the same host system. The problem is, I can’t tell what it does. The two machine reported almost the exact same RAM usage during a buildworld.
Any VMWare/virtualization experts out there able to tell me what needs to be tested to verify this?
If you didn’t know what the Heartbleed bug is, here’s your explanation, plus details. (via). You should probably update your systems.
Francois Tigeot’s rescue ramdisk work is ready for testing. You can pull it directly from his repo and try it out. It’s surprising how small the ramdisk can be crunched.
Note: he now has a newer branch than what is in that linked message.
You know what always makes me happy? When someone shows up out of the blue and says “Here; I did this cause I needed it; everyone can share.” The latest example of that is Imre Vadasz porting bwn(4), for the Broadcom BCM43xx wireless chipset over from FreeBSD to DragonFly.
This is the first Lazy Reading in a while that I hadn’t already started before the previous week’s Lazy Reading was displayed.

Your unrelated comics link of the day: The Very Hungry Rust Monster.
In a thread about video cards on DragonFly, Francois Tigeot listed good ATI cards to try, and pointed out the VESA driver is probably your best bet right now with NVidia cards.
BSDNow 031 is online, with an interview of Pierre Pronchery of EdgeBSD and many other things.
The acpi_thinkpad module (section? code?) has been updated. Update if you are on DragonFly 3.7, or be patient if you are on 3.6.
Normally I don’t bother linking to things on/around April 1st, but these two are good and arrived early.
Update: apparently fake source changes is a thing.
I wrote up some thoughts for the next release of DragonFly. There’s some project work in there for anyone interested. The next release should be near the end of May.
I suddenly can’t remember if I pad my dates with zeros.
Your unrelated link of the week: The creepiest animatronic work I’ve seen yet. (via Orbital Operations)
BSDTalk 239 is 55 minutes of talk with Baptiste Daroussin at vBSDCon 2013 about ‘pkgng’ on FreeBSD. The BSDTalk post doesn’t mention it, but it is the same pkg tool that DragonFly uses, so Baptiste’s plans are relevant to DragonFly too. (I haven’t had a chance to listen to the podcast yet so I don’t know how much he talks about DragonFly, specifically.)
BSDNow episode 030 is out with an interview of Warren Block about FreeBSD documentation, along with a conversation on a number of other topics, including setting up a BSD machine as your access point (highly recommended, along with home router setup) and setting up a BSD (FreeNAS) as a Synology replacement. They also totally scooped me on Michael W. Lucas giving an OpenBSD talk – which might be because I forgot to sign up for his announcement mailing list.
Timezones are a human invention to describe the natural world, so they are changed according to human whims. That’s a grand way to note this change in timezones that is global but I noted in a DragonFly commit of tzdata2014b – look at the last entry.
I’ve been away because of some home construction taking up time, but this has actually been happening for a while: plenty of USB device drivers have been getting ported in to work with the new USB4BSD stack. My links for that are not comprehensive.
One of the requirements to get NSS/LDAP working on (most) any unixlike system is to have dynamic binaries; meaning they are dependent on various libraries to run. Since you’re talking about programs for login when you’re talking about NSS/LDAP, that means if the libraries aren’t available, you can’t log in. DragonFly has static binaries just to avoid that problem.
Francois Tigeot proposed switching to dynamic binaries and building a /rescue directory with static backups, as is the case with I think FreeBSD and NetBSD. If you follow the thread, it looks like the best path is to use initrd instead. Initrd stands for INITial Ram Disk, and is the first volume the computer sets up to boot from BIOS. Since initrd gives the computer enough space to load all the needed modules (like Hammer2…), it works without making the computer dependent on various libraries or having a bloated /rescue directory.
(Someone correct me if I have the details wrong.) As long as we’re talking about things that would help DragonFly in a larger environment, can someone work on a VM balloon memory driver, too?

I have a list of commits I’ve saved between the various BSDs of licenses getting corrected to the 2-clause BSD license; that would definitely be a good cross-BSD project to sync.
BSDNow episode 029 is up containing a full slate of material. There’s an interview of Gleb Kurtsou, along with a PEFS tutorial and several other items that are new to me.
If you noticed the lack of a GUI DVD image for the 3.6 release of DragonFly, I posted a followup note on the users@ list that talks about the steps to get X installed. It’s not much work, with pkg set up.
Sepherosa Ziehau has an IPv6 patch for you to try. What’s it do? I think it improves performance under multiple streams of traffic, but that’s from looking at the code and totally guessing.
Matthew Dillon committed the start of a Hammer 2 cluster API. I noticed, while looking at the commit, that there’s a design document, a freemap design document, a changes list, and – most important for anyone interested – a TODO list.
Alex Hornung has updated tcplay in DragonFly to 2.0, and cryptdisks is updated to match. If you have a short memory, tcplay(8) is the tool on DragonFly to manage TrueCrypt volumes. Is DragonFly the only BSD to have this? I think so, based on very few seconds of googling.
A lot of this was done early; last week had a lot of interesting stuff turn up. Maybe because we’re coming out of a extreme winter in the northern hemisphere, and people are feeling a bit more energetic?

Another week with lots of links.
In part because I asked him, Sepherosa Ziehau benchmarked 10G ix(4) with 2 ports on DragonFly. The results? Good, both for bandwidth and for CPU usage.
Uh oh, I don’t get the pun this time. Anyway, the newest BSDNow episode is an interview with Eric Turgeon of GhostBSD,
and a disk concatenation tutorial for NetBSD and a tutorial that isn’t uploaded yet. (Wait, now I get it.)
A recent commit from Sepherosa Ziehau has a 5% improvement in the number of network connections per second a x86_64 machine can accept. He’s also reducing the number of IPIs during network activity. If this seems somewhat esoteric, it’s because network speeds are getting so fast that the benefits come from reducing the accompanying CPU load.
Sascha Wildner updated the time zone database on DragonFly to tzdata2014a. The odd thing isn’t that update – Sascha updates like clockwork, haha! – but the release notes. Apparently Even Microsoft is starting to support time zone names, sorta, finally.
If you’re on DragonFly 3.7, you will need to build world before building the kernel again if you are updating to some point in the last 24 hours. Sascha Wildner points out the related commit.
Poudriere is the tool for building all of ports/dports, and Michael W. Lucas has written up his experience using it to build a custom ports set. He’s doing on FreeBSD, but if you ignore the geom-specific parts, it should generally apply to DragonFly.
DragonFly has moved from the old USB stack to USB4BSD by default. That means:
- If you are already using USB4BSD, you will want to remove WANT_USB4BSD from your kernel config.
- If you have trouble, switch back to the old USB.
- There’s some drivers that are not yet converted; help with them would be appreciated.
- A full kernel/world build and ‘make upgrade’ will be needed in either case.
Sascha Wildner’s announcement email has all the gory details, including the kernel config changes to move back to the old USB setup. This is of course in master; 3.6 users are unaffected.
This week blew up with links fast.
Your unrelated video of the week: This trailer for Crawl. This is a roguelike multiplayer cross-platform game, though I don’t know if it would work on BSD. The important thing: the voiceover narration is fantastic.
Links everywhere this week!
Hammer’s ability to stream to remote disks is great, but what if you have storage that uses some other file system? Antonio Huete Jimenez put together a shell script that will dump out the contents of a Hammer PFS, for upload to whatever. Read the README for the details.
If you are upgrading packages on your DragonFly 3.6 system, and you have docbook installed, there’s an extra step needed because of the moving around of several docbook packages. If you don’t have docbook installed – nothing to see here.
Episode 27 of BSDNow is an interview with Will Backman of BSDTalk. It is unfortunately a straight-ahead interview, and not an Epic Rap Battle.
Normally I’d save this for Lazy Reading, but I’m indirectly involved: the Rochester Institute of Technology now has a minor in Open Source and Free Culture. Here’s the press release. I taught one of the precursor classes, Humanitarian Free/Open Source Development (essentially open source development methods) last spring. Steve Jacobs was my advisor years ago and Remy Decausemaker was my (best) student from the HFOSS class. In any case, the courses are definitely worth it. (via)
I followed up with Google on why DragonFly isn’t in Summer of Code this year. It is exactly as I suspected: they want to get new organizations in. DragonFly’s been doing it for 6 years, so they are picking new orgs over returning ones. This is apparently the same reason NetBSD isn’t in this year, either.
(Honestly, I can use the break.)
Sascha Wildner has updated arcmsr(4), which brings in support for the Areca ARC1214, ARC1224, ARC1264, ARC1284, and ARC1883 models, from FreeBSD. Please test if you have the appropriate hardware.
bugs.dragonflybsd.org, the bug reporting site for DragonFly, uses Redmine. It’s been updated and now can take OpenID for your login.
BSD Magazine for February is out. I’m a bit late posting this since it’s now March; I assume it’s been out for a while. (via)
If you’re using the i915 driver for xorg, and xorg dies with a “No monitor specified for screen” error, there’s a config change to fix that, or you can just update.
A public service announcement: Check your backup power systems when the weather is bad. It has been so cold that the always-running heater blocks cooked away the coolant in my workplace’s backup generator in between the weekly inspections, and when the power died a few days ago, the generator failed to start. This led to the paradoxical sensor warning: “High coolant temperature” when the outside temperature was below freezing.
- Scott Hanselman wrote “Microsoft killed my Pappy“, where he attributes dislike to Microsoft to being old anger from antitrust suits, etc. Those were more the outcome of frustration over Microsoft quality, as I recall. Microsoft is doing some things right nowadays – generally using open source techniques and sorta working with standards – but then again, so are all the other large tech silos.
- Those who do not know jails are doomed to reinvent them. That’s my description of these container/docker/etc ideas floating around Linux. Yes, I know I’m oversimplifying. (via)

Your unrelated link of the week: Muppets, NYC, and tea. I know it’s an ad, but it fits my interests perfectly.
Another week where I barely need to look up source code commits.
Let’s see… 3 digits in the episode number, so they’re planning to make at least 973 more BSD-related pun titles. Anyway, BSDNow’s latest episode has an interview with Joe Marcus Clark, along with more material including this item that I missed, of getting some ancient hardware to run OpenBSD.
pfi, the automated installer that nobody knows about, now supports installing an authorized_keys file as part of an install. Credit goes to Alex Hornung for adding the functionality.
Sascha Wildner brought in ACPICA 20140214, and his commit message has a list of the updates.
The DragonFly Mail Agent is being suggested as a possible sendmail replacement for FreeBSD.
I’m helping out at the BSD Events website. If there’s upcoming BSD-linked events, please tell me. Speaking of which: the call for papers for EuroBSDCon 2014 is out, as is the BSDCan 2014 schedule.
I am late posting this: the most recent episode of BSDNow has, along with the regular array of items, an interview of Chris Buechler, of the commercial support company behind pfSense.
DragonFly wasn’t accepted for Summer of Code, which frankly I expected to have happen last year – we’ve been participating every year since 2008. However, FreeBSD and (for the first time) OpenBSD are listed as participating mentoring institutions, so you can still get your BSD/GSoC going.
I’ve tagged version 3.6.1 of DragonFly, and built ISO/img files of it. They should be available by now on mirrors if you need them, or you can just upgrade as normal. See the linked tag commit message for what’s changed.
Pardon me as I wander through a lot of topics.
- Where to keep your pubic hair. I worry about this (syntax, not hair storage) when I’m writing titles here. (via)
- Top 100 most searched for out-of-print books in 2013. This is a UK site, so it’s UK-specific, I assume. I am thinking of it because I saw copies of the entertainingly illustrated “UNIX System Administrator’s Handbook” at NYCBSDCon. I have copies of the 3rd edition; the 4th edition in print now is the “UNIX and Linux…” version, and I don’t know if the illustrations survived. (via)
- Also found while looking at the previous links: UNIX Systems Advanced Administration and Management Handbook. No idea of the contents, since it’s nearly 20 years old, but the cover hints that it might be interesting more for the style of how it was assembled and what it covers, rather than the technical aspects. I am entertained by ‘first edition’ AD&D manuals the same way.
- It’s about time. DDOS attacks and NTP. A summary of the recent trend.

Your unrelated comics link of the week: Top Shelf is now selling their excellent comics without DRM, so they can be stored/read however you like.
Read the first item, if nothing else.
Grep /var/run/dmesg.boot for PMM, and if it turns up, Sepherosa Ziehau has a patch he’d like you to try.
See the announcement, and the commit. I’m not totally sure what this affects.
If you have i915 chipset-based video on DragonFly, and you get a “Output xxx has no Monitor section” complaint in your xorg logs, look at this fix using xrandr.
Here’s two recent changes in DragonFly that may interest you if you have an AMD processor: Compute Units are now supported, thanks to Mihai Carabas, and Imre Vadasz ported over km(4), for temperature monitoring on 14h and 15h CPUs. I’m still not totally clear on what Compute Units are.
I was remiss in not posting this before it happened, but Issac (.ike) Levy of NYCBUG went to Tokyo to talk about the translation efforts for pfSense, on the 17th. He posted a summary of his talk and slides.
Normally I would be posting this in an “In Other BSDs” Saturday item, but the summary page includes links on Open Network Hardware, which .ike and I talked about at NYCBSDCon. I wanted to create a separate post for it, but he’s got all the links piled in with his talk summary already.
The hardware I want to see as a real product is the Intel ONP Switch Reference Design. (PDF) Having a device that looks like a switch but is actually a normal computer with a lot of network ports – that can run BSD – opens up a huge range of network possibilities.
As I mentioned on kernel@, I’m going to roll a point release of DragonFly soon. Push in your changes if you want to get them in!
