364: FreeBSD Wireless Grind
FreeBSD Qt WebEngine GPU Acceleration, the grind of FreeBSD’s wireless stack, thoughts on overlooking Illumos's syseventadm, when Unix learned to reboot, New EXT2/3/4 File-System driver in DragonflyBSD, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines FreeBSD Qt WebEngine GPU Acceleration (https://euroquis.nl/freebsd/2020/07/21/webengine.html) FreeBSD has a handful of Qt WebEngine-based browsers. Falkon, and Otter-Browser, and qutebrowser and probably others, too. All of them can run into issues on FreeBSD with GPU-accelerated rendering not working. Let’s look at some of the workarounds. NetBSD on the Nanopi Neo2 (https://www.cambus.net/netbsd-on-the-nanopi-neo2/) The NanoPi NEO2 from FriendlyARM has been serving me well since 2018, being my test machine for OpenBSD/arm64 related things. As NetBSD/evbarm finally gained support for AArch64 in NetBSD 9.0, released back in February, I decided to give it a try on this device. The board only has 512MB of RAM, and this is where NetBSD really shines. Things have become a lot easier since jmcneill@ now provides bootable ARM images for a variety of devices, including the NanoPi NEO2. I'm back into the grind of FreeBSD's wireless stack and 802.11ac (https://adrianchadd.blogspot.com/2020/07/im-back-into-grind-of-freebsds-wireless.html) Yes, it's been a while since I posted here and yes, it's been a while since I was actively working on FreeBSD's wireless stack. Life's been .. well, life. I started the ath10k port in 2015. I wasn't expecting it to take 5 years, but here we are. My life has changed quite a lot since 2015 and a lot of the things I was doing in 2015 just stopped being fun for a while. But the stars have aligned and it's fun again, so here I am. News Roundup Some thoughts on us overlooking Illumos's syseventadm (https://utcc.utoronto.ca/~cks/space/blog/solaris/OverlookingSyseventadm) In a comment on my praise of ZFS on Linux's ZFS event daemon, Joshua M. Clulow noted that Illumos (and thus OmniOS) has an equivalent in syseventadm, which dates back to Solaris. I hadn't previously known about syseventadm, despite having run Solaris fileservers and OmniOS fileservers for the better part of a decade, and that gives me some tangled feelings. When Unix learned to reboot (https://bsdimp.blogspot.com/2020/07/when-unix-learned-to-reboot2.html) Recently, a friend asked me the history of halt, and when did we have to stop with the sync / sync / sync dance before running halt or reboot. The two are related, it turns out. DragonFlyBSD Lands New EXT2/3/4 File-System Driver (https://www.phoronix.com/scan.php?page=news_item&px=DragonFlyBSD-New-EXT2FS) While DragonFlyBSD has its own, original HAMMER2 file-system, for those needing to access data from EXT2/EXT3/EXT4 file-systems, there is a brand new "ext2fs" driver implementation for this BSD operating system. DragonFlyBSD has long offered an EXT2 file-system driver (that also handles EXT3 and EXT4) while hitting their Git tree this week is a new version. The new sys/vfs/ext2fs driver, which will ultimately replace their existing sys/gnu/vfs/ext2fs driver is based on a port from FreeBSD code. As such, this driver is BSD licensed rather than GPL. But besides the more liberal license to jive with the BSD world, this new driver has various feature/functionality improvements over the prior version. However, there are some known bugs so for the time being both file-system drivers will co-exist.

363: Traditional Unix toolchains
FreeBSD Q2 Quarterly Status report of 2020, Traditional Unix Toolchains, BastilleBSD 0.7 released, Finding meltdown on DragonflyBSD, and more NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines FreeBSD Quarterly Report (https://www.freebsd.org/news/status/report-2020-04-2020-06.html) This report will be covering FreeBSD related projects between April and June, and covers a diverse set of topics ranging from kernel updates over userland and ports, as well to third-party work. Some highlights picked with the roll of a d100 include, but are not limited to, the ability to forcibly unmounting UFS when the underlying media becomes inaccessible, added preliminary support for Bluetooth Low Energy, a introduction to the FreeBSD Office Hours, and a repository of software collections called potluck to be installed with the pot utility, as well as many many more things. As a little treat, readers can also get a rare report from the quarterly team. Finally, on behalf of the quarterly team, I would like to extend my deepest appreciation and thank you to salvadore@, who decided to take down his shingle. His contributions not just the quarterly reports themselves, but also the surrounding tooling to many-fold ease the work, are immeasurable. Traditional Unix Toolchains (https://bsdimp.blogspot.com/2020/07/traditional-unix-toolchains.html?m=1) Older Unix systems tend to be fairly uniform in how they handle the so-called 'toolchain' for creating binaries. This blog will give a quick overview of the toolchain pipeline for Unix systems that follow the V7 tradition (which evolved along with Unix, a topic for a separate blog maybe). Unix is a pipeline based system, either physically or logically. One program takes input, process the data and produces output. The input and output have some interface they obey, usually text-based. The Unix toolchain is no different. News Roundup Bastille Day 2020 : v0.7 released (https://github.com/BastilleBSD/bastille/releases/tag/0.7.20200714) This release matures the project from 0.6.x -> 0.7.x. Continued testing and bug fixes are proving Bastille capable for a range of use-cases. New (experimental) features are examples of innovation from community contribution and feedback. Thank you.

361: Function-based MicroVM
Emulex: The Cheapest 10gbe for Your Homelab, In Search of 2.11BSD, as released, Fakecracker: NetBSD as a Function Based MicroVM, First powerpc64 snapshots available for OpenBSD, OPNsense 20.1.8 released, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines Emulex: The Cheapest 10gbe for Your Homelab (https://vincerants.com/emulex-the-cheapest-10gbe/) Years ago, the hunt for the cheapest 10gbe NICs resulted in buying Mellanox ConnectX-2 single-port 10gbe network cards from eBay for around $10. Nowadays those cards have increased in cost to around $20-30. While still cheap, not quite the cheapest. There are now alternatives! Before diving into details, let’s get something very clear. If you want the absolute simplest plug-and-play 10gbe LAN for your homelab, pay the extra for Mellanox. If you’re willing to go hands-on, do some simple manual configuration and installation, read on for my experiences with Emulex 10gbe NICs. Emulex NICs can often be had for around $15 on eBay, sometimes even cheaper. I recently picked up a set of 4 of these cards, which came bundled with 6 SFP+ 10g-SR modules for a grand total of $47.48. Considering I can usually find SFP+ modules for about $5/ea, these alone were worth $30. + I have also tried some Solarflare cards that I found cheap, they work ok, but are pickier about optics, and tend to be focused on low-latency, so often don’t manage to saturate the full 10 gbps, topping out around 8 gbps. + I have been using fs.com for optics, patch cables, and DACs. I find DACs are usually cheaper if you are just going between a server and a switch in the same rack, or direct between 2 servers. In Search of 2.11BSD, as released (https://bsdimp.blogspot.com/2020/07/211bsd-original-tapes-recreation.html) Almost all of the BSD releases have been well preserved. If you want to find 1BSD, or 2BSD or 4.3-TAHOE BSD you can find them online with little fuss. However, if you search for 2.11BSD, you'll find it easily enough, but it won't be the original. You'll find either the latest patched version (2.11BSD pl 469), or one of the earlier popular version (pl 430 is popular). You can even find the RetroBSD project which used 2.11BSD as a starting point to create systems for tiny mips-based PIC controllers. You'll find every single patch that's been issued for the system. News Roundup Fakecracker: NetBSD as a Function Based MicroVM (https://imil.net/blog/posts/2020/fakecracker-netbsd-as-a-function-based-microvm/) In November 2018 AWS published an Open Source tool called Firecracker, mostly a virtual machine monitor relying on KVM, a small sized Linux kernel, and a stripped down version of Qemu. What baffled me was the speed at which the virtual machine would fire up and run the service. The whole process is to be compared to a container, but safer, as it does not share the kernel nor any resource, it is a separate and dedicated virtual machine. If you want to learn more on Firecracker‘s internals, here’s a very well put article. First powerpc64 snapshots available for OpenBSD (https://undeadly.org/cgi?action=article;sid=20200707001113) Since we reported the first bits of powerpc64 support going into the tree on 16 May, work has progressed at a steady pace, resulting in snapshots now being available for this platform. So, if you have a POWER9 system idling around, go to your nearest mirror and fetch this snapshot. Keep in mind that as this is still very early days, very little handholding is available - you are basically on your own. OPNsense 20.1.8 released (https://opnsense.org/opnsense-20-1-8-released/) Sorry about the delay while we chased a race condition in the updates back to an issue with the latest FreeBSD package manager updates. For now we reverted to our current version but all relevant third party packages have been updated as updates became available over the last weeks, e.g. cURL and Python, and hostapd / wpa_supplicant amongst others.

360: Full circle
Chasing a bad commit, New FreeBSD Core Team elected, Getting Started with NetBSD on the Pinebook Pro, FreeBSD on the Intel 10th Gen i3 NUC, pf table size check and change, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines Chasing a bad commit (https://vishaltelangre.com/chasing-a-bad-commit/) While working on a big project where multiple teams merge their feature branches frequently into a release Git branch, developers often run into situations where they find that some of their work have been either removed, modified or affected by someone else's work accidentally. It can happen in smaller teams as well. Two features could have been working perfectly fine until they got merged together and broke something. That's a highly possible case. There are many other cases which could cause such hard to understand and subtle bugs which even continuous integration (CI) systems running the entire test suite of our projects couldn't catch. We are not going to discuss how such subtle bugs can get into our release branch because that's just a wild territory out there. Instead, we can definitely discuss about how to find a commit that deviated from an expected outcome of a certain feature. The deviation could be any behaviour of our code that we can measure distinctively — either good or bad in general. New FreeBSD Core Team Elected (https://www.freebsdnews.com/2020/07/14/new-freebsd-core-team-elected/) The FreeBSD Project is pleased to announce the completion of the 2020 Core Team election.

Let’s install NetBSD instead! The easiest way to get started is to buy a decent micro-SD card (what sort of markings it should have is a science of its own, by the way) and install NetBSD on that. On a warm boot (i.e. when rebooting a running system), the micro-SD card has priority compared to the eMMC, so the system will boot from there. + A FreeBSD developer has borrowed some of the NetBSD code to get audio working on RockPro64 and Pinebook Pro: https://twitter.com/kernelnomicon/status/1282790609778905088 FreeBSD on the Intel 10th Gen i3 NUC (https://adventurist.me/posts/00300) I have ended up with some 10th Gen i3 NUC's (NUC10i3FNH to be specific) to put to work in my testbed. These are quite new devices, the build date on the boxes is 13APR2020. Before I figure out what their true role is (one of them might have to run linux) I need to install FreeBSD -CURRENT and see how performance and hardware support is. pf table size check and change (https://www.dragonflydigest.com/2020/06/29/24698.html) Did you know there’s a default size limit to pf’s state table? I did not, but it makes sense that there is one. If for some reason you bump into this limit (difficult for home use, I’d think), here’s how you change it (http://lists.dragonflybsd.org/pipermail/users/2020-June/381261.html) There is a table-entries limit specified, you can see current settings with 'pfctl -s all'. You can adjust the limits in the /etc/pf.conf file containing the rules with a line like this near the top: set limit table-entries 100000 + In the original mail thread, there is mention of the FreeBSD sysctl net.pf.request_maxcount, which controls the maximum number of entries that can be sent as a single ioctl(). This allows the user to adjust the memory limit for how big of a list the kernel is willing to allocate memory for.

359: Throwaway Browser
Throw-Away Browser on FreeBSD With "pot" within 5 minutes, OmniOS as OpenBSD guest with bhyve, BSD vs Linux distro development, My FreeBSD Laptop Build, FreeBSD CURRENT Binary Upgrades, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines Throw-Away Browser on FreeBSD With "pot" Within 5 Minutes (https://honeyguide.eu/posts/pot-throwaway-firefox/) pot is a great and relatively new jail management tool. It offers DevOps style provisioning and can even be used to provide Docker-like, scalable cloud services together with nomad and consul (more about this in Orchestrating jails with nomad and pot). OpenBSD guest with bhyve - OmniOS (https://www.pbdigital.org/omniosce/bhyve/openbsd/2020/06/08/bhyve-zones-omnios.html) Today I will be creating a OpenBSD guest via bhyve on OmniOS. I will also be adding a Pass Through Ethernet Controller so I can have a multi-homed guest that will serve as a firewall/router. This post will cover setting up bhyve on OmniOS, so it will also be a good introduction to bhyve. As well, I look into OpenBSD’s uEFI boot loader so if you have had trouble with this, then you are in the right place. News Roundup BSD versus Linux distribution development (https://distrowatch.com/weekly.php?issue=20200622#qa) Q: Comparing-apples-to-BSDs asks: I was reading one of the old articles from the archive. One of the things mentioned was how the BSDs have a distinct approach in terms of packaging the base system relative to userland apps, and that the Linux distros at the time were not following the same practice. Are there Linux distros that have adopted the same approach in modern times? If not, are there technical limitations that are preventing them from doing so, such as some distros supporting multiple kernel versions maybe? DistroWatch answers: In the article mentioned above, I made the observation that Linux distributions tend to take one of two approaches when it comes to packaging software. Generally a Linux distribution will either offer a rolling release, where virtually all packages are regularly upgraded to their latest stable releases, or a fixed release where almost all packages are kept at a set version number and only receive bug fixes for the life cycle of the distribution. Projects like Arch Linux and Void are popular examples of rolling, always-up-to-date distributions while Fedora and Ubuntu offer fixed platforms. My FreeBSD Laptop Build (https://corrupted.io/2020/06/21/my-freebsd-laptop-build.html) I have always liked Thinkpad hardware and when I started to do more commuting I decided I needed something that had a decent sized screen but fit well on a bus. Luckily about this time Lenovo gave me a nice gift in the Thinkpad X390. Its basically the famous X2xx series but with a 13” screen and smaller bezel. So with this laptop I figured it was time to actually put the docs together on how I got my FreeBSD workstation working on it. I will here in the near future have another post that will cover this for HardenedBSD as well since the steps are similar but have a few extra gotchas due to the extra hardening.

358: OpenBSD Kubernetes Clusters
Yubikey-agent on FreeBSD, Managing Kubernetes clusters from OpenBSD, History of FreeBSD part 1, Running Jitsi-Meet in a FreeBSD Jail, Command Line Bug Hunting in FreeBSD, Game of Github, Wireguard official merged into OpenBSD, and more NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines yubikey-agent on FreeBSD (https://kernelnomicon.org/?p=855) Some time ago Filippo Valsorda wrote yubikey-agent, seamless SSH agent for YubiKeys. I really like YubiKeys and worked on the FreeBSD support for U2F in Chromium and pyu2f, getting yubikey-agent ported looked like an interesting project. It took some hacking to make it work but overall it wasn’t hard. Following is the roadmap on how to get it set up on FreeBSD. The actual details depend on your system (as you will see) Manage Kubernetes clusters from OpenBSD (https://e1e0.net/manage-k8s-from-openbsd.html) This should work with OpenBSD 6.7. I write this while the source tree is locked for release, so even if I use -current this is as close as -current gets to -release Update 2020-06-05: we now have a port for kubectl. So, at least in -current things get a bit easier. News Roundup History of FreeBSD Part 1: Unix and BSD (https://klarasystems.com/articles/history-of-freebsd-unix-and-bsd/?utm_source=bsdnow) FreeBSD, a free and open-source Unix-like operating system has been around since 1993. However, its origins are directly linked to that of BSD, and further back, those of Unix. During this History of FreeBSD series, we will talk about how Unix came to be, and how Berkeley’s Unix developed at Bell Labs. Running Jitsi-Meet in a FreeBSD Jail (https://honeyguide.eu/posts/jitsi-freebsd/) Due to the situation with COVID-19 that also lead to people being confined to their homes in South Africa as well, we decided to provide a (freely usable of course) Jitsi Meet instance to the community being hosted in South Africa on our FreeBSD environment. That way, communities in South Africa and beyond have a free alternative to the commercial conferencing solutions with sometimes dubious security and privacy histories and at the same time improved user experience due to the lower latency of local hosting. + Grafana for Jitsi-Meet (https://honeyguide.eu/posts/jitsi-grafana/) Command Line Bug Hunting in FreeBSD (https://adventurist.me/posts/00301) FreeBSD uses bugzilla for tracking bugs, taking feature requests, regressions and issues in the Operating System. The web interface for bugzilla is okay, but if you want to do a lot of batch operations it is slow to deal with. We are planning to run a bugsquash on July 11th and that really needs some tooling to help any hackers that show up process the giant bug list we have.

OpenBSD 6.7 on PC Engines, NetBSD code study, DRM Update on OpenBSD, Booting FreeBSD on HPE Microserver SATA port, 3 ways to multiboot, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines OpenBSD 6.7 on PC Engines APU4D4 (https://www.tumfatig.net/20200530/openbsd-6-7-on-pc-engines-apu4d4/) I just got myself a PC Engines APU4D4. I miss an OpenBSD box providing home services. It’s quite simple to install and run OpenBSD on this machine. And you can even update the BIOS from OpenBSD. NetBSD code study (http://silas.net.br/codereading/netbsd-code.html) News Roundup Booting FreeBSD off the HPE MicroServer Gen8 ODD SATA port (https://rubenerd.com/booting-freebsd-off-the-microserver-odd-sata-port/) My small homelab post generated a ton of questions and comments, most of them specific to running FreeBSD on the HP MicroServer.

356: Dig in Deeper
TrueNAS is Multi-OS, Encrypted ZFS on NetBSD, FreeBSD’s new Code of Conduct, Gaming on OpenBSD, dig a little deeper, Hammer2 and periodic snapshots, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines TrueNAS is Multi-OS (https://www.ixsystems.com/blog/truenas-multi-os/) There was a time in history where all that mattered was an Operating System (OS) and the hardware it ran on — the “pre-software era”, if you will. Your hardware dictated the OS you used. Once software applications became prominent, your hardware’s OS determined the applications you could run. Application vendors were forced to juggle the burden of “portability” between OS platforms, choosing carefully the operating systems they’d develop their software to. Then, there were the great OS Wars of the 1990s, replete with the rampant competition, licensing battles, and nasty lawsuits, which more or less gave birth to the “open source OS” era. The advent of the hypervisor simultaneously gave way to the “virtual era” which set us on a path of agnosticism toward the OS. Instead of choosing from the applications available for your chosen OS, you could simply install another OS on the same hardware for your chosen application. The OS became nothing but a necessary cog in the stack. TrueNAS open storage enables this “post-OS era” with support for storage clients of all UNIX flavors, Linux, FreeBSD, Windows, MacOS, VMware, Citrix, and many others. Containerization has carried that mentality even further. An operating system, like the hardware that runs it, is now just thought of as part of the “infrastructure”. Encrypted ZFS on NetBSD 9.0, for a FreeBSD guy (https://rubenerd.com/encrypted-zfs-on-netbsd-9-for-a-freebsd-guy/) I had one of my other HP Microservers brought back from the office last week to help with this working-from-home world we’re in right now. I was going to wipe an old version of Debian Wheezy/Xen and install FreeBSD to mirror my other machines before thinking: why not NetBSD? News Roundup FreeBSD's New Code of Conduct (https://www.freebsd.org/internal/code-of-conduct.html) FreeBSD Announcement Email (https://raw.githubusercontent.com/BSDNow/bsdnow.tv/master/episodes/356/FBSD-CoC-Email) Gaming on OpenBSD (https://dataswamp.org/~solene/2020-06-05-openbsd-gaming.html) While no one would expect this, there are huge efforts from a small team to bring more games into OpenBSD. In fact, now some commercial games works natively now, thanks to Mono or Java. There are no wine or linux emulation layer in OpenBSD. Here is a small list of most well known games that run on OpenBSD: 'dig' a little deeper (https://vishaltelangre.com/dig-a-little-deeper/) I knew the existence of the dig command but didn't exactly know when and how to use it. Then, just recently I encountered an issue that allowed me to learn and make use of it. HAMMER2 and periodic snapshots (https://www.dragonflydigest.com/2020/06/15/24635.html) The first version of HAMMER took automatic snapshots, set within the config for each filesystem.

355: Man Page Origins
Upgrading OpenBSD, Where do Unix man pages come from?, Help for NetBSD’s VAX port, FreeBSD on Dell Latitude 7390, PFS Tool changes in DragonflyBSD, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines How to Upgrade OpenBSD and Build a Kernel (https://cromwell-intl.com/open-source/openbsd-kernel.html) Let's see how to upgrade your OpenBSD system. Maybe you are doing this because the latest release just came out. If so, this is pretty simple: back up your data, boot from install media, and select "Upgrade" instead of "Install". But maybe the latest release has been out for a few months. Why would we go through the trouble of building and installing a new kernel or other core system components? Maybe some patches have been released to improve system security or stability. It is pretty easy to build and install a kernel on OpenBSD, easier and simpler in many ways than it is on Linux. The History of man pages (https://manpages.bsd.lv/history.html) Where do UNIX manpages come from? Who introduced the section-based layout of NAME, SYNOPSIS, and so on? And for manpage authors: where were those economical two- and three-letter instructions developed? VAX port needs help (http://blog.netbsd.org/tnf/entry/vax_port_needs_help) The VAX is the oldest machine architecture still supported by NetBSD. Unfortunately there is another challenge, totally outside of NetBSD, but affecting the VAX port big time: the compiler support for VAX is ... let's say sub-optimal. It is also risking to be dropped completely by gcc upstream. Now here is where people can help: there is a bounty campaign to finance a gcc hacker to fix the hardest and most immediate issue with gcc for VAX. Without this being resolved, gcc will drop support for VAX in a near future version. My new FreeBSD Laptop: Dell Latitude 7390 (http://www.daemonology.net/blog/2020-05-22-my-new-FreeBSD-laptop-Dell-7390.html) As a FreeBSD developer, I make a point of using FreeBSD whenever I can — including on the desktop. I've been running FreeBSD on laptops since 2004; this hasn't always been easy, but over the years I've found that the situation has generally been improving. One of the things we still lack is adequate documentation, however — so I'm writing this to provide an example for users and also Google bait in case anyone runs into some of the problems I had to address. PFS tool changes in DragonFly (https://www.dragonflydigest.com/2020/06/09/24612.html) HAMMER2 just became a little more DWIM: the pfs-list and pfs-delete directives will now look across all mounted filesystems, not just the current directory’s mount path. pfs-delete won’t delete any filesystem name that appears in more than one place, though + git: hammer2 - Enhance pfs-list and pfs-delete (http://lists.dragonflybsd.org/pipermail/commits/2020-June/769226.html) Enhance pfs-list to list PFSs available across all mounted hammer2 filesystems instead of just the current directory's mount. A specific mount may be specified via -s mountpt. Enhance pfs-delete to look for the PFS name across all mounted hammer2 filesystems instead of just the current directory's mount. As a safety, pfs-delete will refuse to delete PFS names which are duplicated across multiple mounts. A specific mount may be specified via -s mountpt.

News Roundup Understanding How OpenZFS Keeps Your Data Safe (https://www.ixsystems.com/blog/openzfs-keeps-your-data-safe/) Veteran technology writer Jim Salter wrote an excellent guide on the ZFS file system’s features and performance that we absolutely had to share. There’s plenty of information in the article for ZFS newbies and advanced users alike. Be sure to check out the article over at Ars Technica to learn more about ZFS concepts including pools, vdevs, datasets, snapshots, and replication, just to name a few. Bringing FreeBSD to ec2 (https://www.lastweekinaws.com/podcast/screaming-in-the-cloud/bringing-freebsd-to-ec2-with-colin-percival/) Colin is the founder of Tarsnap, a secure online backup service which combines the flexibility and scriptability of the standard UNIX "tar" utility with strong encryption, deduplication, and the reliability of Amazon S3 storage.

353: ZFS on Ironwolf
Scheduling in NetBSD, ZFS vs. RAID on Ironwolf disks, OpenBSD on Microsoft Surface Go 2, FreeBSD for Linux sysadmins, FreeBSD on Lenovo T480, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/) Headlines Scheduling in NetBSD – Part 1 (https://manikishan.wordpress.com/2020/05/10/scheduling-in-netbsd-part-1/) In this blog, we will discuss about the 4.4BSD Thread scheduler one of the two schedulers in NetBSD and a few OS APIs that can be used to control the schedulers and get information while executing. ZFS versus RAID: Eight Ironwolf disks, two filesystems, one winner (https://arstechnica.com/gadgets/2020/05/zfs-versus-raid-eight-ironwolf-disks-two-filesystems-one-winner/) This has been a long while in the making—it's test results time. To truly understand the fundamentals of computer storage, it's important to explore the impact of various conventional RAID (Redundant Array of Inexpensive Disks) topologies on performance. It's also important to understand what ZFS is and how it works. But at some point, people (particularly computer enthusiasts on the Internet) want numbers. If you want to hear more from Jim, he has a new bi-weekly podcast with Allan and Joe Ressington over at 2.5admins.com (https://2.5admins.com/) News Roundup OpenBSD on the Microsoft Surface Go 2 (https://jcs.org/2020/05/15/surface_go2) I used OpenBSD on the original Surface Go back in 2018 and many things worked with the big exception of the internal Atheros WiFi. This meant I had to keep it tethered to a USB-C dock for Ethernet or use a small USB-A WiFi dongle plugged into a less-than-small USB-A-to-USB-C adapter. FreeBSD UNIX for Linux sysadmins (https://triosdevelopers.com/jason.eckert/blog/Entries/2020/5/2_FreeBSD_UNIX_for_Linux_sysadmins.html) If you’ve ever installed and explored another Linux distro (what Linux sysadmin hasn’t?!?), then exploring FreeBSD is going be somewhat similar with a few key differences. While there is no graphical installation, the installation process is straightforward and similar to installing a server-based Linux distro. Just make sure you choose the local_unbound package when prompted if you want to cache DNS lookups locally, as FreeBSD doesn’t have a built-in local DNS resolver that does this. Following installation, the directory structure is almost identical to Linux. Of course, you’ll notice some small differences here and there (e.g. regular user home directories are located under /usr/home instead of /home). Standard UNIX commands such as ls, chmod, find, which, ps, nice, ifconfig, netstat, sockstat (the ss command in Linux) are exactly as you’d expect, but with some different options here and there that you’ll see in the man pages. And yes, reboot and poweroff are there too. FreeBSD on the Lenovo Thinkpad T480 (https://www.davidschlachter.com/misc/t480-freebsd) Recently I replaced my 2014 MacBook Air with a Lenovo Thinkpad T480, on which I've installed FreeBSD, currently 12.1-RELEASE.

352: Introducing Randomness
A brief introduction to randomness, logs grinding netatalk to a halt, NetBSD core team changes, Using qemu guest agent on OpenBSD kvm/qemu guests, WireGuard patchset for OpenBSD, FreeBSD 12.1 on a laptop, and more. Headlines Entropy (https://washbear.neocities.org/entropy.html) A brief introduction to randomness Problem: Computers are very predictable. This is by design. But what if we want them to act unpredictably? This is very useful if we want to secure our private communications with randomized keys, or not let people cheat at video games, or if we're doing statistical simulations or similar. Logs grinding Netatalk on FreeBSD to a hault (https://rubenerd.com/logs-grinding-netatalk-on-freebsd-to-a-hault/) I’ve heard it said the cobbler’s children walk barefoot. While posessing the qualities of a famed financial investment strategy, it speaks to how we generally put more effort into things for others than ourselves; at least in business. The HP Microserver I share with Clara is a modest affair compared to what we run at work. It has six spinning rust drives and two SSDs which are ZFS-mirrored; not even in a RAID 10 equivalent. This is underlaid with GELI for encryption, and served to our Macs with Netatalk over gigabit Ethernet with jumbo frames. News Roundup NetBSD Core Team Changes (https://mail-index.netbsd.org/netbsd-announce/2020/05/07/msg000314.html) Matt Thomas (matt@) has served on the NetBSD core team for over ten years, and has made many contributions, including ELF functionality, being the long-time VAX maintainer, gcc contributor, the generic pmap, and also networking functionality, and platform bring-up over the years. Matt has stepped down from the NetBSD core team, and we thank him for his many, extensive contributions. Robert Elz (kre@), a long time BSD contributor, has kindly accepted the offer to join the core team, and help us out with the benefit of his experience and advice over many years. Amongst other things, Robert has been maintaining our shell, liaising with the Austin Group, and bringing it up to date with modern functionality. Using qemu guest agent on OpenBSD kvm/qemu guests (https://undeadly.org/cgi?action=article;sid=20200514073852) In a post to the ports@ mailing list, Landry Breuil (landry@) shared some of his notes on using qemu guest agent on OpenBSD kvm/qemu guests. WireGuard patchset for OpenBSD (https://undeadly.org/cgi?action=article;sid=20200512080047) A while ago I wanted to learn more about OpenBSD development. So I picked a project, in this case WireGuard, to develop a native client for. Over the last two years, with many different iterations, and working closely with the WireGuard's creator (Jason [Jason A. Donenfeld - Ed.], CC'd), it started to become a serious project eventually reaching parity with other official implementations. Finally, we are here and I think it is time for any further development to happen inside the src tree. FreeBSD 12.1 on a laptop (https://dataswamp.org/~solene/2020-05-11-freebsd-workstation.html) I’m using FreeBSD again on a laptop for some reasons so expect to read more about FreeBSD here.

351: Heaven: OpenBSD 6.7
Backup and Restore on NetBSD, OpenBSD 6.7 available, Building a WireGuard Jail with FreeBSD's standard tools, who gets to chown things and quotas, influence TrueNAS CORE roadmap, and more. Headlines Backup and Restore on NetBSD (https://e17i.github.io/articles-netbsd-backup/) Putting together the bits and pieces of a backup and restore concept, while not being rocket science, always seems to be a little bit ungrateful. Most Admin Handbooks handle this topic only within few pages. After replacing my old Mac Mini's OS by NetBSD, I tried to implement an automated backup, allowing me to handle it similarly to the time machine backups I've been using before. Suggestions on how to improve are always welcome. BSD Release: OpenBSD 6.7 (https://distrowatch.com/?newsid=10921) The OpenBSD project produces and operating system which places focus on portability, standardisation, code correctness, proactive security and integrated cryptography. The project's latest release is OpenBSD 6.7 which introduces several new improvements to the cron scheduling daemon, improvements to the web server daemon, and the top command now offers scrollable output. These and many more changes can be found in the project's release announcement: "This is a partial list of new features and systems included in OpenBSD 6.7. For a comprehensive list, see the changelog leading to 6.7. General improvements and bugfixes: Reduced the minimum allowed number of chunks in a CONCAT volume from 2 to 1, increasing the number of volumes which can be created on a single disk with bioctl(8) from 7 to 15. This can be used to create more partitions than previously. Rewrote the cron(8) flag-parsing code to be getopt-like, allowing tight formations like -ns and flag repetition. Renamed the 'options' field in crontab(5) to 'flags'. Added crontab(5) -s flag to the command field, indicating that only a single instance of the job should run concurrently. Added cron(8) support for random time values using the ~ operator. Allowed cwm(1) configuration of window size based on percentage of the master window during horizontal and vertical tiling actions." Release Announcement (https://marc.info/?l=openbsd-announce&m=158989783626149&w=2) Release Notes (https://www.openbsd.org/67.html) News Roundup Building a WireGuard Jail with the FreeBSD's Standard Tools (https://genneko.github.io/playing-with-bsd/networking/freebsd-wireguard-jail/) Recently, I had an opportunity to build a WireGuard jail on a FreeBSD 12.1 host. As it was really quick and easy to setup and it has been working completely fine for a month, I’d like to share my experience with anyone interested in this topic. The Unix divide over who gets to chown things, and (disk space) quotas (https://utcc.utoronto.ca/~cks/space/blog/unix/ChownDivideAndQuotas) One of the famous big splits between the BSD Unix world and the System V world is whether ordinary users can use chown (the command and the system call) to give away their own files. In System V derived Unixes you were generally allowed to; in BSD derived Unixes you weren't. Until I looked it up now to make sure, I thought that BSD changed this behavior from V7 and that V7 had an unrestricted chown. However, this turns out to be wrong; in V7 Unix, chown(2) was restricted to root only. You Can Influence the TrueNAS CORE Roadmap! (https://www.ixsystems.com/blog/truenas-bugs-and-suggestions/) As many of you know, we’ve historically had three ticket types available in our tracker: Bugs, Features, and Improvements, which are all fairly self-explanatory. After some discussion internally, we’ve decided to implement a new type of ticket, a “Suggestion”. These will be replacing Feature and Improvement requests for the TrueNAS Community, simplifying things down to two options: Bugs and Suggestions. This change also introduces a slightly different workflow than before.

And in true mythic style, it contains the seeds of its own eclipse. This is my subjective historical narrative of how that happened. I’m using the name “Unix” to include the entire family of operating systems descended from it, or that have been heavily influenced by it. That includes Linux, SunOS, Solaris, BSD, Mac OS X, and many, many others. Both major mobile OSs, Android and iOS, have Unix roots. Their billions of users dwarf those using clunky things like laptops and desktops, but even there, Windows is only the non-Unix viable OS. Almost everything running server-side in giant datacenters is Linux. How did Unix win? News Roundup Check logs of central syslog-ng log host on FreeBSD (https://blog.socruel.nu/freebsd/check-logs-of-syslog-ng-log-host-on-freebsd.html) This blog post continues where the blog post A central log host with syslog-ng on FreeBSD left off.
