Created by three guys who love BSD, we cover the latest news and have an extensive series of tutorials, as well as interviews with various people from all areas of the BSD community. It also serves as a platform for support and questions. We love and advocate FreeBSD, OpenBSD, NetBSD, DragonFlyBSD and TrueOS. Our show aims to be helpful and informative for new users that want to learn about them, but still be entertaining for the people who are already pros. The show airs on Wednesdays at 2:00PM (US Eastern time) and the edited version is usually up the following day.

406: Jailed Gemini Capsule
Gemini Capsule in a FreeBSD Jail, FreeBSD Quarterly status report 2021Q1, NetBSD VM on bhyve (on TrueNAS), Interview with Michael Lucas, WireGuard Returns as Experimental Package in pfSense, CGI with Awk on OpenBSD httpd, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines Gemini Capsule in a FreeBSD Jail (https://www.ecliptik.com/Gemini-Capsule-in-a-FreeBSD-Jail/) With the recent release of FreeBSD 13, I wanted to test it out on a spare RaspberryPi 3 that was part of my old Kubernetes cluster. In particular, FreeBSD Jails have always interested me, although I’ve never used them in practice. Over the years I’ve managed operating system virtualization through Solaris Zones and Docker containers, and Jails seem like and good middle ground between the two - easier to manage than zones and closer to the OS than Docker. I also want to run my own Gemini capsule locally to use some of the features that my other hosted capsules don’t have (like SCGI/CGI) and setting up a capsule in a Jail is a good way to learn both at the same time. FreeBSD Quarterly status report 2021Q1 (https://lists.freebsd.org/pipermail/freebsd-announce/2021-May/002033.html) News Roundup NetBSD VM on bhyve (on TrueNAS) (https://bentsukun.ch/posts/bhyve-netbsd/) My new NAS at home is running TrueNAS Core. So far, it has been excellent, however I struggled a bit setting up a NetBSD VM on it. Part of the problem is that a lot of the docs and how-tos I found are stale, and the information in it no longer applies. TrueNAS Core allows running VMs using bhyve, which is FreeBSD’s hypervisor. NetBSD is not an officially supported OS, at least according to the guest OS chooser in the TrueNAS web UI :) But since the release of NetBSD 9 a while ago, things have become far simpler than they used to be – with one caveat (see below). Interview with Michael Lucas *BSD, Unix, IT and other books author (https://www.cyberciti.biz/interview/michael-lucas-bsd-unix-it-and-other-books-author/) Michael Lucas is a famous IT book author. Perhaps best know for FreeBSD, OpenBSD, and Unix book series. He worked as a system administrator for many years and has now become a full-time book writer.

405: OOM Killer Feature
NetBSD 9.2 released, DragonFly 6.0 is out, Home Network Monitoring using Prometheus, Preventing FreeBSD to kill PostgreSQL, Customizing Emacs for Git Commit Messages, Deleting old FreeBSD boot environments, Always be quitting, and more NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines NetBSD 9.2 Released (http://blog.netbsd.org/tnf/entry/netbsd_9_2_released) DragonFly 6.0 is out! (https://www.dragonflydigest.com/2021/05/10/25731.html) Release Notes (https://www.dragonflybsd.org/release60/) *** ### EuroBSDCon 2021 will be online (https://2021.eurobsdcon.org/) *** ## News Roundup ### Home Network Monitoring using Prometheus (https://linux-bsd.github.io/post/monitoring/) > This blog post describes my setup for monitoring various devices on my home network suh as servers, laptops/desktops, networking gear etc. The setup and configuration is squarely geared towards small/medium sized network monitoring. A similar setup might work for large networks, but you will need to plan your compute/storage/bandwidth capacities accordingly. I’m running all the monitoring software on FreeBSD, but you can run it on your choice of OS. Just make sure to install the packages using your OS’s package manager. *** ### Preventing FreeBSD to kill PostgreSQL (aka OOM Killer prevention) (https://fluca1978.github.io/2021/04/02/OOMKillerFreeBSD.html) > There are a lot of interesting articles on how to prevent the Out of Memory Killer (OOM killer in short) on Linux to ruin your day, or better your night. One particularly well done explanation about how the OOM Killer works, and how to help PostgreSQL to survive, is, in my humble opinion, the one from Percona Blog. *** ### Customizing Emacs for Git Commit Messages (http://bsdimp.blogspot.com/2021/04/customizing-emacs-for-git-commit.html) >I do a lot of commits to the FreeBSD project and elsewhere. It would be nice if I could setup emacs in a custom way for each commit message that I'm editing. > Fortunately, GNU Emacs provides a nice way to do just that. While I likely could do some of these things with git commit hooks, I find this to be a little nicer. *** ### Deleting old FreeBSD boot environments (https://dan.langille.org/2021/04/15/deleting-old-freebsd-boot-environments/) > I like boot environments (BE) on FreeBSD. They were especially handy when building the AWS host for FreshPorts, since I had no serial console. I would create a BE saving the current status, then make some changes. I’d mark the current BE as boot once, so I could boot back in the known good BE. Worst case, I could mount the storage onto a rescue EC2 instance and adjust the bootfs value of the zpool. *** Always be quitting (https://jmmv.dev/2021/04/always-be-quitting.html) A good philosophy to live by at work is to “always be quitting”. No, don’t be constantly thinking of leaving your job. But act as if you might leave on short notice. Counterintuitively, this will make you a better engineer and open up growth opportunities.

403: The Linuxulator Investment
Why You Should Use BSD Licensing for Your Next Open Source Project or Product, Update on FreeBSD Foundation Investment in Linuxulator, OPNsense 21.1.5 released, FreeBSD meetings on the Desktop, Running FreeBSD jails with containerd 1.5, Markdown, DocBook, and the quest for semantic documentation on NetBSD.org, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines Why You Should Use BSD Licensing for Your Next Open Source Project or Product (https://klarasystems.com/articles/why-you-should-use-bsd-licensing-for-your-next-open-source-project-or-product/) The term “open source” has its origins in the context of software development, designating a specific approach to developing computer programs. Nowadays, however, it stands for a broad set of values – open source means open exchange, transparency, collaborative participation and development for the benefit of the entire community. Update on FreeBSD Foundation Investment in Linuxulator (https://freebsdfoundation.org/blog/update-on-freebsd-foundation-investment-in-linuxulator/) Dr. Emmett Brown’s similar-sounding Flux Capacitor from the movie Back to the Future bridged the dimension of time, uniting past, present, and future for the McFlys. Similarly, the FreeBSDⓇ Linuxulator project also bridges dimensions – in our case, these are LinuxⓇ and FreeBSD. News Roundup OPNsense 21.1.5 released (https://opnsense.org/opnsense-21-1-5-released/) This is mainly a security and reliablility update. There are several FreeBSD security advisories and updates for third party tools such as curl. + OPNsense to rebase on FreeBSD 13 (https://forum.opnsense.org/index.php?topic=22761.msg108313#msg108313) FreeBSD meetings on the Desktop (https://euroquis.nl//freebsd/2021/04/20/fbsd-bbb.html) FreeBSD on the desktop is a whole stack - X11, Qt, KDE Frameworks, KDE Plasma and KDE Gear, and Wayland, and Poppler and GTK - o my! Running FreeBSD jails with containerd 1.5 (https://samuel.karp.dev/blog/2021/05/running-freebsd-jails-with-containerd-1-5/) containerd 1.5.0 was released today and now works on a new operating system: FreeBSD! This new release includes a series of patches (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) which allow containerd to build, enable the native and zfs snapshotters, and use a compatible runtime like runj. Markdown, DocBook, and the quest for semantic documentation on NetBSD.org (https://washbear.neocities.org/markdown.html) Recently, I’ve been doing a lot of maintenance of the NetBSD website. It contains a boatload of documentation, much of which was originally written in the 2000s. It has some special requirements: it has to work in text-based web browsers like lynx, or maybe even without any working browser installed at all, or just ftp(1) for downloading plain text over HTTP. Naturally, the most important parts are static, suitable for serving from the standard NetBSD http server, which runs from inetd by default.

402: Goodbye GPL
It's time to say goodbye to the GPL, a new OCI Runtime for FreeBSD Jails, A bit of Xenix history, On Updating QEMU's bsd-user fork, FreeBSD 13 on a 12 year old laptop, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines It's time to say goodbye to the GPL (https://martin.kleppmann.com/2021/04/14/goodbye-gpl.html) The trigger for this post is the reinstating of Richard Stallman, a very problematic character, to the board of the Free Software Foundation (FSF). I am appalled by this move, and join others in the call for his removal. This occasion has caused me to reevaluate the position of the FSF in computing. It is the steward of the GNU project (a part of Linux distributions, loosely speaking), and of a family of software licenses centred around the GNU General Public License (GPL). These efforts are unfortunately tainted by Stallman’s behaviour. However, this is not what I actually want to talk about today. runj: a new OCI Runtime for FreeBSD Jails (https://samuel.karp.dev/blog/2021/03/runj-a-new-oci-runtime-for-freebsd-jails/) Today, I open-sourced runj, a new experimental, proof-of-concept OCI-compatible runtime for FreeBSD jails. For the past 6.5 years I’ve been working on Linux containers, but never really had much experience with FreeBSD jails. runj (pronounced “run jay”) is a vehicle for me to learn more about FreeBSD in general and jails in particular. With my position on the Technical Oversight Board of the Open Containers Initiative, I’m also interested in understanding how the OCI runtime specification can be adapted to other operating systems like FreeBSD. News Roundup A Bit of Xenix History (http://seefigure1.com/2014/04/15/xenixtime.html) From 1986 to 1989, I worked in the Xenix1 group at Microsoft. It was my first job out of school, and I was the most junior person on the team. I was hopelessly naive, inexperienced, generally clueless, and borderline incompetent, but my coworkers were kind, supportive and enormously forgiving – just a lovely bunch of folks. On Updating QEMU's bsd-user fork (https://bsdimp.blogspot.com/2021/05/on-updating-qemus-bsd-user-fork.html) FreeBSD 13 on a 12 year old laptop (http://box.matto.nl/freebsd-13-on-a-12-year-old-laptop.html) My old (2009) HP laptop now runs FreeBSD 13.0-RELEASE.

401: OpenBSD Dog Garage
Dog's Garage Runs OpenBSD, EuroBSDcon 2021 Call for Papers, FreeBSD’s iostat, The state of toolchains in NetBSD, Bandwidth limiting on OpenBSD 6.8, FreeBSD's ports migration to git and its impact on HardenedBSD, TrueNAS 12.0-U3 has been released, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines My Dog's Garage Runs OpenBSD (https://undeadly.org/cgi?action=article;sid=20210415055717) I was inspired by the April 2017 article in undeadly.org about getting OpenBSD running on a Raspberry Pi 3B+. My goal was to use a Raspberry Pi running OpenBSD to monitor the temperature in my garage from my home. My dog has his own little "apartment" inside the garage, so I want to keep an eye on the temperature. (I don't rely on this device. He sleeps inside the house whenever he wants.) EuroBSDcon 2021 Call for Papers (https://2021.eurobsdcon.org/about/cfp/) FreeBSD iostat (https://klarasystems.com/articles/freebsd-iostat-a-quick-glance/) The state of toolchains in NetBSD (https://www.cambus.net/the-state-of-toolchains-in-netbsd/) While FreeBSD and OpenBSD both switched to using LLVM/Clang as their base system compiler, NetBSD picked a different path and remained with GCC and binutils regardless of the license change to GPLv3. However, it doesn't mean that the NetBSD project endorses this license, and the NetBSD Foundation's has issued a statement about its position on the subject. NetBSD’s statement (http://cvsweb.netbsd.org/bsdweb.cgi/src/external/gpl3/README?rev=1.1) *** News Roundup Bandwidth limiting on OpenBSD 6.8 (https://dataswamp.org/~solene/2021-02-07-limit.html) I will explain how to limit bandwidth on OpenBSD using its firewall PF (Packet Filter) queuing capability. It is a very powerful feature but it may be hard to understand at first. What is very important to understand is that it's technically not possible to limit the bandwidth of the whole system, because once data is getting on your network interface, it's already there and got by your router, what is possible is to limit the upload rate to cap the download rate. FreeBSD's ports migration to git and its impact on HardenedBSD (https://hardenedbsd.org/article/shawn-webb/2021-04-06/freebsds-ports-migration-git-and-its-impact-hardenedbsd) FreeBSD completed their ports migration from subversion to git. Prior to the official switch, we used the read-only mirror FreeBSD had at GitHub[1]. The new repo is at [2]. A cursory glance at the new repo will show that the commit hashes changed. This presents an issue with HardenedBSD's ports tree in our merge-based workflow. TrueNAS 12.0-U3 has been released (https://www.truenas.com/docs/releasenotes/core/12.0u3/) iXsystems is excited to announce TrueNAS 12.0-U3 was released today and marks an important milestone in the transition from FreeNAS to TrueNAS. TrueNAS 12.0 is now considered by iXsystems to be a higher quality release than FreeNAS 11.3-U5, our previous benchmark. The new TrueNAS documentation site has also reached a point where it has more content and capabilities than FreeNAS. TrueNAS 12.0 is ready for mission-critical enterprise deployments.

400: FreeBSD became 13
FreeBSD 13 is here, multi-factor authentication on OpenBSD, KDE on FreeBSD 2021o2, NetBSD GSoC report, a working D compiler on OpenBSD, and more NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines FreeBSD 13.0 R Annoucement (https://www.freebsd.org/releases/13.0R/announce/) • OpenZFS 2.0 (almost 2.1) is included in 13.0 • Removed support for previously-deprecated algorithms in geli(8). • The armv8crypto(4) driver now supports AES-GCM which is used by IPsec and kernel TLS. Enable multi-factor authentication on OpenBSD (https://dataswamp.org/~solene/2021-02-06-openbsd-2fa.html) In this article I will explain how to add a bit more security to your OpenBSD system by adding a requirement for user logging into the system, locally or by ssh. I will explain how to setup 2 factor authentication (2FA) using TOTP on OpenBSD News Roundup KDE on FreeBSD 2021o2 (https://euroquis.nl/kde/2021/03/26/freebsd2021o2.html) Gosh, second octant already! Well, let’s take a look at the big things that happened in KDE-on-FreeBSD in these six-and-a-half weeks. GSoC Reports: Make system(3), popen(3) and popenve(3) use posix_spawn(3) internally (Final report) (http://blog.netbsd.org/tnf/entry/gsoc_reports_make_system_31) My code can be found at github.com/teknokatze/src in the gsoc2020 branch, at the time of writing some of it is still missing. The test facilities and logs can be found in github.com/teknokatze/gsoc2020. A diff can be found at github which will later be split into several patches before it is sent to QA for merging. The initial and defined goal of this project was to make system(3) and popen(3) use posixspawn(3) internally, which had been completed in June. For the second part I was given the task to replace fork+exec calls in our standard shell (sh) in one scenario. Similar to the previous goal we determined through implementation if the initial motivation, to get performance improvements, is correct otherwise we collect metrics for why posixspawn() in this case should be avoided. This second part meant in practice that I had to add and change code in the kernel, add a new public libc function, and understand shell internals. A working D compiler on OpenBSD (https://undeadly.org/cgi?action=article;sid=20210322080633) Dr. Brian Robert Callahan (bcallah@) blogged about his work in getting D compiler(s) working under OpenBSD. + Full Post (https://briancallahan.net/blog/20210320.html) Tarsnap This weeks episode of BSDNow was sponsored by our friends at Tarsnap, the only secure online backup you can trust your data to.
