Normally I’d hold this off until the In Other BSDs item on Saturday, but by then it will be too late: There’s a “Building redundant and transparent firewalls with OpenBSD” presentation happening at the Scottish Linux User’s Group meeting, Thursday night in Glasgow, Scotland.
Normally if I talk about a filesystem here, I talk about Hammer, which is not a surprise. However, I often read and review Michael W. Lucas’s BSD-oriented books, and he has written FreeBSD Mastery: Storage Essentials. I’m reviewing it here because it’s obviously BSD-related, and some portions are directly relevant for other BSDs.
Disk setup and layout isn’t something that normally consumes much attention past the initial install – until something goes wrong, or until a system needs a new configuration. Installers tend to hide that initial layout, anyway.
Vendors take advantage of this. Much of the specialized storage vendors out there are selling you a computer with disks in it – something you can build yourself. You don’t (or at least I hope you don’t) buy a firewall when you can do the same with pf or ipfw; the same goes for disk management.
There’s plenty of coverage of GEOM, GELI, GDBE, and the other technologies specific to FreeBSD. I for one did not know how GEOM worked, with its consumer/producer model – and I imagine it’s complex to dive into when you’ve got a broken machine next to you. If you are administering FreeBSD systems, especially ones that deal with dedicated storage, you will find this useful. He doesn’t go into ZFS, but he does hint at a book on it later…
If you’re not a FreeBSD user, there’s also material that’s common to any BSD – an explanation of disk architecture, of UFS, RAID, and SMART. Knowing what SMART is and does is essential, in my opinion. You may be able to cobble this material together from other sources online, but it’s packaged nicely here, with Lucas’s easy writing style.
It’s a self-published book, and as such the download nets you three different formats. It’s currently $10 and DRM-free, directly from the author. You can also order physical versions, if you like paper.

Can someone with experience on Google Compute Engine try out running DragonFly on it? There’s FreeBSD instructions, so it might work.
The short answer is ath(4) and iwn(4), via this post. There’s an update coming for the wireless infrastructure in DragonFly; Matthew Dillon and Adrian Chadd (on the FreeBSD side) are working together for improvements.
While I’m mentioning recommendations, the Silicon Image 3132 chipset is apparently excellent for eSATA drives on DragonFly.
Francois Tigeot has performed a major upgrade of DragonFly’s sound system. If you had sound problems or unsupported hardware before, this may fix them. It will require a full buildworld+buildkernel.
I managed to miss this last week because of issues with my RSS feeds, but the 71st episode of BSDNow is/has been up. It’s “systemd isaster”, cause the interview is with Ian Sutton talking about BSD replacements for systemd dependencies. There’s a number of at-least-slightly DragonFly-related things in there, including OPNSense, pkgng, and Hammer mentions.

The CAM layer in DragonFly has had its big lock removed/been marked MPSAFE, so you will notice a performance increase when using multiple disks. (assuming you aren’t throughput-limited, of course.)
There’s a FreeBSD Forums thread about ZFS and Hammer, as several people have pointed out to me. It’s interesting to see, but there isn’t a lot of quantitative discussion. (It’s a forum post, not a white paper, though.)
Do you remember the BSDNow story a while ago about a Tanzanian community effort using FreeBSD to build a library? They’re looking at DragonFly, too, because of the low resource requirements. From that discussion: a hardware reason for an ‘indefinite wait buffer’ error, and a note on how to most efficiently download packages for multiple machines.
Sepherosa Ziehau has posted a note that V4-mapped addressing is no longer supported in DragonFly. You will need to do a full buildworld/buildkernel if you are running master. Also, TCP MTU path discovery is on by default. Also also, he’s added a SOL_SOCKET/SO_CPUINT socket option for use to reduce load in heavy network activity. As usual, I don’t quite comprehend.

I’m moved over to new hardware for the Digest. Tell me if you see issues, please.
The BSDNow people aren’t slowing down for the holidays, as there’s another episode this week. The interview is with Dan Langille, about the 2015 BSDCan conference. He’s also the person behind freebsddiary.org, which served as partial inspiration for the Digest. There’s also more video presentation links, news items, and so on.
shiningsilence.com/dragonflydigest.com will be going down for a brief period in the next 24 hours, for a hardware upgrade.
John Marino has created something very useful: a graphical tool for Hammer file history. It’s called ‘Slider’, and it uses curses to work in a terminal. It shows historic versions of files and can restore those old versions as needed. This was already possible in Hammer, of course, but it required a sequence of commands that were not straight-forward. I’ve been slow enough posting it that version 2.0 is already out, offering a way to see files that no longer exist, but are still in history. (i.e. deleted some time ago) ‘Time Machine’ sounds like the best name, but that seems to be taken.
I’m going to dive right in with an anecdote: As is normal for anyone in systems administration, I’m busy at work. I’ve been short an employee for some time, and I brought in a managed service provider to do some work. This included a revamping of the network equipment and layout, as it has been growing organically rather than in a planned fashion.
I received the formal assessment from the provider a few weeks ago, and it mentioned that we were using a non ICSA-certified firewall: pf, in the form of pfSense. This was accompanied by some rather drastic warnings about how open source was targeted by hackers! and implied that ICSA certification was a mark of quality rather than a purchasable certification. All bogus, of course.
The reason I’m starting this review with this little story is to note that while open source has become well-accepted for system and application software, there’s still a lot of people that expect commercial hardware to be exclusively handling data once it leaves the server. That’s been valid for a long time, but software like pf represents a realistic option, or even an improvement, over many commercial and proprietary options. Since pf exists in one form or another on all the BSDs, it’s a tool you should be at least somewhat familiar with.
Peter N. M. Hansteen has written about pf first online, and then in printed form, for some time. The Book of PF is in its third edition, and that’s what I have to read. (Disclosure: No Starch Press gave me the book free, without requirements)
The book is excellent, and easier to read than I expected for a book about network processing. It can be read in linear form, as it takes the reader from simple to more complex network layouts. It works as a reference book, too, as it focuses on different tools around pf and what they are used for.
It covers the different pf version in OpenBSD, NetBSD, and FreeBSD, and DragonFly gets at least a partial mention in some portions of the book. For example, OpenBSD recently removed ALTQ, but the other BSDs still use it. With- and without-ALTQ scenarios are covered every place it applies. You’re going to get the most mileage out of an OpenBSD setup with it, though.
The parts where the book shines are the later chapters; the descriptions of greylisting and spamd, the traffic shaping notes, and the information on monitoring pf will be useful for most anyone. It’s quite readable; similar in tone to Peter’s blog. If you enjoy his in-depth online articles, the book will be a pleasant read.

BSDNow isn’t slowing down for Christmas, cause there’s a new episode up. There’s two interviews this time – Erwin Lansing, about BSD in Europe, and Cristina Vintila, about BSD conferences. The rest of the episode is a bunch of “How did you get into BSD?” stories from viewers, both in text (i.e. read out from email) and the occasional video answer.
One way to keep file history on an very active Hammer disk from eating up all the space: more snapshots. This may seem counterproductive, but disk pruning eliminates historical data between snapshots, so you can keep older data at the cost of some temporal accuracy.
As part of another thread, Steve Petrie posted an in-depth description of how and where and why he’s using DragonFly. Worth looking at either for workflow tips or for just seeing the use case.
BSDTalk 249 is an 11 minute interview with Scott Long, who is involved with Netflix’s FreeBSD-based local caching appliances. This conversation is from MeetBSD 2014, though I heard Scott talk about the same subject at the last NYCBSDCon – it’s an astounding amount of data flowing through those machines.

It’s possible, if you are several releases (years) behind, to end up with a DragonFly system that can’t compile and install the current release, due to incremental changes over time. It’s rare, but it could happen now between, say, version 3.4 and 4.0. The usual solution would be to incrementally upgrade in order, which is a lot of building and updating. The alternative is the new installworld-force option from Matthew Dillon that forces a new set of binaries into place. Use as a last resort.
If you want to help I/O performance when DragonFly is virtualized, here’s a short checklist of what to work on. I haven’t noticed any problems – but I’m not taxing any of my VMs that heavily.
BSDNow’s episode this week focuses on the just-released Bitrig 1.0, and has an interview with Patrick Wildt of that project. There’s also coverage of other topics, including the new poudriere release – that’s the tool that bulk builds packages for DragonFly and FreeBSD, though I don’t know if it’s unified across both operating systems yet.
bycn82’s rewrite of IPFW2 is available as a git branch to try out; he’s posted the link. Please try, especially if you are still working with the original ipfw.
(note: remember, ‘ipfw’ in DragonFly is what was called ‘ipfw2′ years and years ago because it was a replacement of the original ‘ipfw’ in FreeBSD. It was called ipfw2 but referenced as ipfw so that the same commands worked. Technically, this branch bycn82 is working on would be ipfw3, but he keeps referring to it as ipfw2. Confused? Good.)
If you’re using one of those Acer C720 or C720p Chromebooks with DragonFly, remember to set:

The 66th BSDNow episode has an interview with Paul Schenkeveld about BSD conferences, and of course the usual variety of news, including something about a BSD-powered library in Africa; something that is entirely out of the blue to me.
In an effort to reduce my backlog of DragonFly things to post about, here’s quick notes:
- The path to xauth is now configurable, though correct by default. (that’s bit me in the past)
- There’s a new callout*() implementation.
- cpuctl(4) has been imported to allow CPU microcode updates.
- libm has been updated with math functions from FreeBSD and NetBSD, which because of library versioning support, won’t cause compatibility problems for older vs. newer DragonFly versions.
- C++11 support is also now available.

Predrag Punosevac posted his writeup of using LDAP and DragonFly, which I’m noting here for the next person that needs LDAP authentication.
This week’s BSDNow episode, 8,000,000 Mogofoo-ops, includes an interview with Brendan Gregg of Netflix, along with more recent convention video links. It also mentions GNOME3 working on FreeBSD – it’s working on DragonFly too.
With a recent commit from Sascha Wildner, DragonFly now loads XHCI (meaning USB3) by default. If you had previously tried to install DragonFly via USB stick, and it inexplicably refused to mou t the installer drive… It may work much better now.
The 4.0 release of DragonFly is out! Quoting from the release page:
Version 4 of DragonFly brings Haswell graphics support, 3D acceleration, and improved performance in extremely high-traffic networks. DragonFly now supports up to 256 CPUs, Haswell graphics (i915), concurrent pf operation, and a variety of other devices.
The more eagle-eyed downloader will notice it’s version 4.0.1, not 4.0.0. That’s because
nobody trusts .0 releases I tagged 4.0.0 just before a few useful commits went in, and it’s better to retag to make sure everyone got them. See also my message to kernel@/users@
I’ve placed an image slider over on the right side of the website; it’s all BSD-related books. Each image is linked to a page about the book where you can buy it. It’s not paid advertising, or perhaps advertising at all; there’s no in-kind benefit. It’s specifically books I think people would find interesting to read, and we’d all benefit by the expansion of the BSD ‘ecosystem’.
The most recent edition added is Michael W. Lucas’s FreeBSD Mastery: Storage Essentials, which is out in ebook form today, and printed form soon.
Lots to read this week.
- The Open Source Financial Developers Association has a very complete calendar of open source events around NYC. (via)
- Google Code-in 2014 has announced its mentoring orgs.
- Also, Google Summer of Code 2015 has been announced.
- Facebook’s New Data Center Is Bad News for Cisco. Somewhat free of technical data, but I do like the idea of more software-defined networking. (via)
- NSA vs. encryption, 40 years ago. (via)
- schmutz. Ah, the joys of Unicode. (via)
- Sort of related: this is just mean. (via IRC, I think)
- SSHelper. I’m going to buy a new phone just so I can use this. I want my handheld computer to actually be a computer, darnit. This is from the guy who created Apple Writer, of all things. (also via)
- List of Physical Visualizations. (via)
- After Docker. Docker and similar items appear to be an attempt to change an operating system from a place where you work to a thin wrapping around a program you run. Dunno if I like that. (via)
- Barbie, computer engineer, which has created more responses.
- A brief history of graphics. Video game graphics, specifically.
- The Nostalgia Nerds Who Rescue Old Games From Oblivion. Similar. (via)
- I like the concept behind “Let’s Encrypt“, though I quibble with the tools selected. (via)
- A video about the Internet in 1995. (via)
- “With varying degrees, everyone has this drawer in their house.“
- IFComp winners will provide a great deal of reading/playing time.
Your unrelated link of the week: Snowpocalypse 2014. I grew up there and now live not too far away. That’s really not that much snow for the area; it’s just that it fell so quickly.
I actually got this started early, for once, instead of completing in a panic on Friday night.
- The Move from Linux to FreeBSD. (via)

BSDNow 064 (somehow, 64 seems a nicer milestone than 50) links to a huge pile of EuroBSDCon 2014 videos, including 2 DragonFly presentations. There’s also an interview with Justin Cormack, who must be cool; I can tell from his name. There’s a lot more material just written on the page after the video, so I’ll point you at the actual content instead of repeating.
A fellow whom I’ve only seen named as Bill is working on what he calls ipfw2, though technically what’s already in DragonFly is ipfw2, since it’s the second version of ipfw. Either way, he has a project page up describing what he’s done so far, and what he plans.
Markus Pfeiffer has made usb_pf work on DragonFly, which means it’s possible to dump USB traffic and filter it, similar to tcpdump. This can be handy when debugging a USB device, and that’s like 90% of all devices anyway.
Snow snow snow!
- DoomRL, a Doom roguelike. From Hasso Tepper, who correctly pointed out I haven’t been linking enough roguelike material lately.
- Unix: Catching up with Unix errors.
- True Stuff: Build Your Own Propeller Car. Not so much about the car as about the building part.
- Making Internet Local. A deep dive into what everyone calls ‘mesh networking’ and what that really means.
- “The alternative Windows Store” I guess sounds better than win64 package manager. Anyway, the idea of a ports collection is becoming universal.
- Command-line Unix-style note taker.
- Sample the Amen Break. Hey, a Squarepusher video gets in there. (via)
- Receiving NOAA Weather Images with SDR. Sounds fun to build, though I know I won’t get to it. (via)
- What is the URL to your technical blog? More things to read there.
- New Found Sounds, early synthesizers. (also via)
- XScreenSaver 5.31. “To make this work I had to add a UTF8 parser to my VT100 implementation”

If you look at your local DragonFly mirror, you’ll see ISO and IMG versions of DragonFly 4.0.0RC3. Please run, break, and report.
(Check the iso-images directory.)
Imre Vadaz’s recent change to dev/drm, adding kqueue support, has (from anecdotal reports in IRC) made video performance much better. It’s committed to DragonFly 4.0, so it’ll be in the next release.
BSDNow 063 has the normal news articles and links, and an interview of Kristaps Džonsons, one of the people working on mandoc. There’s also a tutorial on bandwidth throttling with pf.
