FuryBSD 2020Q2 Images Available for XFCE and KDE

The Q2 2020 images are not a visible leap forward but a functional leap forward. Most effort was spent creating a better out of box experience for automatic Ethernet configuration, working WiFi, webcam, and improved hypervisor support.

Technical reasons to choose FreeBSD over GNU/Linux

Since I wrote my article "Why you should migrate everything from Linux to BSD" I have been wanting to write something about the technical reasons to choose FreeBSD over GNU/Linux and while I cannot possibly cover every single reason, I can write about some of the things that I consider worth noting.

+ Not actually Linux distro review deux: GhostBSD

When I began work on the FreeBSD 12.1-RELEASE review last week, it didn't take long to figure out that the desktop portion wasn't going very smoothly.

I think it's important for BSD-curious users to know of easier, gentler alternatives, so I did a little looking around and settled on GhostBSD for a follow-up review.

GhostBSD is based on TrueOS, which itself derives from FreeBSD Stable. It was originally a Canadian distro, but—like most successful distributions—it has transcended its country of origin and can now be considered worldwide. Significant GhostBSD development takes place now in Canada, Italy, Germany, and the United States.

“TLS Mastery” sponsorships open

My next book will be TLS Mastery, all about Transport Layer Encryption, Let’s Encrypt, OCSP, and so on.

This should be a shorter book, more like my DNSSEC or Tarsnap titles, or the first edition of Sudo Mastery. I would like a break from writing doorstops like the SNMP and jails books.

Tale of OpenBSD secure memory allocator internals - malloc(3)

Hi there,

It's been a very long time I haven't written anything after my last OpenBSD blogs, that is,

OpenBSD Kernel Internals — Creation of process from user-space to kernel space.

OpenBSD: Introduction to execpromises in the pledge(2)

pledge(2): OpenBSD's defensive approach to OS Security

So, again I started reading OpenBSD source codes with debugger after reducing my sleep timings and managing to get some time after professional life. This time I have picked one of my favourite item from my wishlist to learn and share, that is, OpenBSD malloc(3), secure allocator

How I learned to stop worrying and love SSDs

my home FreeNAS runs two pools for data. One RAIDZ2 with four spinning disk drives and one mirror with two SSDs. Toying with InfluxDB and Grafana in the last couple of days I found that I seem to have a constant write load of 1 Megabyte (!) per second on the SSDs. What the ...?

So I run three VMs on the SSDs in total. One with Windows 10, two with Ubuntu running Confluence, A wiki essentially, with files for attachments and MySQL as the backend database. Clearly the writes had to stop when the wikis were not used at all, just sitting idle, right?

Well even with a full query log and quite some experience in the operation of web applications I could not figure out what Confluence is doing (productively, no doubt) but trust me, it writes a couple of hundred kbytes to the database each second just sitting idle.

My infrastructure as of 2019

I've wanted to write about my infrastructure for a while, but I kept thinking, "I'll wait until after I've done $next_thing_on_my_todo." Of course this cycle never ends, so I decided to write about its state at the end of 2019. Maybe I'll write an update on it in a couple of moons; who knows?

Fighting the Coronavirus with FreeBSD

Here is a quick HOWTO for those who want to provide some FreeBSD based compute resources to help finding vaccines.

UPDATE 2020-03-22: 0mp@ made a port out of this, it is in “biology/linux-foldingathome”.

Per default it will now pick up some SARS-CoV‑2 (COVID-19) related folding tasks. There are some more config options (e.g. how much of the system resources are used). Please refer to the official Folding@Home site for more information about that. Be also aware that there is a big rise in compute resources donated to Folding@Home, so the pool of available work units may be empty from time to time, but they are working on adding more work units. Be patient.

How to configure the Wireguard VPN in OPNsense

WireGuard is a modern designed VPN that uses the latest cryptography for stronger security, is very lightweight, and is relatively easy to set up (mostly). I say ‘mostly’ because I found setting up WireGuard in OPNsense to be more difficult than I anticipated. The basic setup of the WireGuard VPN itself was as easy as the authors claim on their website, but I came across a few gotcha's. The gotcha's occur with functionality that is beyond the scope of the WireGuard protocol so I cannot fault them for that. My greatest struggle was configuring WireGuard to function similarly to my OpenVPN server. I want the ability to connect remotely to my home network from my iPhone or iPad, tunnel all traffic through the VPN, have access to certain devices and services on my network, and have the VPN devices use my home's Internet connection.

WireGuard behaves more like a SSH server than a typical VPN server. With WireGuard, devices which have shared their cryptographic keys with each other are able to connect via an encrypted tunnel (like a SSH server configured to use keys instead of passwords). The devices that are connecting to one another are referred to as “peer” devices. When the peer device is an OPNsense router with WireGuard installed, for instance, it can be configured to allow access to various resources on your network. It becomes a tunnel into your network similar to OpenVPN (with the appropriate firewall rules enabled). I will refer to the WireGuard installation on OPNsense as the server rather than a “peer” to make it more clear which device I am configuring unless I am describing the user interface because that is the terminology used interchangeably by WireGuard.

The documentation I found on WireGuard in OPNsense is straightforward and relatively easy to understand, but I had to wrestle with it for a little while to gain a better understanding on how it should be configured. I believe it was partially due to differing end goals – I was trying to achieve something a little different than the authors of other wiki/blog/forum posts. Piecing together various sources of information, I finally ended up with a configuration that met the goals stated above.

NomadBSD 1.3.1 has recently been made available. NomadBSD is a lightweight and portable FreeBSD distribution, designed to run on live on a USB flash drive, allowing you to plug, test, and play on different hardware. They have also started a forum as of yesterday, where you can ask questions and mingle with the NomadBSD community. Notable changes in 1.3.1 are base system upgraded to FreeBSD 12.1-p2. automatic network interface setup improved, image size increased to over 4GB, Thunderbird, Zeroconf, and some more listed below.

GhostBSD 20.02

Eric Turgeon, main developer of GhostBSD, has announced version 20.02 of the FreeBSD based operating system. Notable changes are ZFS partition into the custom partition editor installer, allowing you to install alongside with Windows, Linux, or macOS. Other changes are force upgrade all packages on system upgrade, improved update station, and powerd by default for laptop battery performance.

New FuryBSD XFCE and KDE images

This new release is now based on FreeBSD 12.1 with the latest FreeBSD quarterly packages. This brings XFCE up to 4.14, and KDE up to 5.17. In addition to updates this new ISO mostly addresses community bugs, community enhancement requests, and community pull requests. Due to the overwhelming amount of reports with GitHub hosting all new releases are now being pushed to SourceForge only for the time being. Previous releases will still be kept for archive purposes.

pf-badhost 0.3 Released

pf-badhost is a simple, easy to use badhost blocker that uses the power of the pf firewall to block many of the internet's biggest irritants. Annoyances such as SSH and SMTP bruteforcers are largely eliminated. Shodan scans and bots looking for webservers to abuse are stopped dead in their tracks. When used to filter outbound traffic, pf-badhost blocks many seedy, spooky malware containing and/or compromised webhosts.

Meet FuryBSD: A New Desktop BSD Distribution

At its heart, FuryBSD is a very simple beast. According to the site, “FuryBSD is a back to basics lightweight desktop distribution based on stock FreeBSD.” It is basically FreeBSD with a desktop environment pre-configured and several apps preinstalled. The goal is to quickly get a FreeBSD-based system running on your computer.

You might be thinking that this sounds a lot like a couple of other BSDs that are available, such as NomadBSD and GhostBSD. The major difference between those BSDs and FuryBSD is that FuryBSD is much closer to stock FreeBSD. For example, FuryBSD uses the FreeBSD installer, while others have created their own installers and utilities.

As it states on the site, “Although FuryBSD may resemble past graphical BSD projects like PC-BSD and TrueOS, FuryBSD is created by a different team and takes a different approach focusing on tight integration with FreeBSD. This keeps overhead low and maintains compatibility with upstream.” The lead dev also told me that “One key focus for FuryBSD is for it to be a small live media with a few assistive tools to test drivers for hardware.”

Currently, you can go to the FuryBSD homepage and download either an XFCE or KDE LiveCD. A GNOME version is in the works.

NetBSD 9.0

The NetBSD Project is pleased to announce NetBSD 9.0, the seventeenth major release of the NetBSD operating system.

This release brings significant improvements in terms of hardware support, quality assurance, security, along with new features and hundreds of bug fixes. Here are some highlights of this new release.

OpenBSD Foundation 2019 campaign wrapup

Our target for 2019 was CDN$300K. Our community's continued generosity combined with our corporate donors exceeded that nicely. In addition we received the largest single donation in our history, CDN$380K from Smartisan. The return of Google was another welcome event. Altogether 2019 was our most successful campaign to date, yielding CDN$692K in total.

We thank all our donors, Iridium (Smartisan), Platinum (Yandex, Google), Gold (Microsoft, Facebook) Silver (2Keys) and Bronze (genua, Thinkst Canary). But especially our community of smaller donors whose contributions are the bedrock of our support. Thank you all!

A retrospective on our OmniOS ZFS-based NFS fileservers

Our OmniOS fileservers have now been out of service for about six months, which makes it somewhat past time for a retrospective on them. Our OmniOS fileservers followed on our Solaris fileservers, which I wrote a two part retrospective on (part 1, part 2), and have now been replaced by our Linux fileservers. To be honest, I have been sitting on my hands about writing this retrospective because we have mixed feelings about our OmniOS fileservers.

I will put the summary up front. OmniOS worked reasonably well for us over its lifespan here and looking back I think it was almost certainly the right choice for us at the time we made that choice (which was 2013 and 2014). However it was not without issues that marred our experience with it in practice, although not enough to make me regret that we ran it (and ran it for as long as we did). Part of our issues are likely due to a design mistake in making our fileservers too big, although this design mistake was probably magnified when we were unable to use Intel 10G-T networking in OmniOS.

On the one hand, our OmniOS fileservers worked, almost always reliably. Like our Solaris fileservers before them, they ran quietly for years without needing much attention, delivering NFS fileservice to our Ubuntu servers; specifically, we ran them for about five years (2014 through 2019, although we started migrating away at the end of 2018). Over this time we had only minor hardware issues and not all that many disk failures, and we suffered no data loss (with ZFS checksums likely saving us several times, and certainly providing good reassurances). Our overall environment was easy to manage and was pretty much problem free in the face of things like failed disks. I'm pretty sure that our users saw a NFS environment that was solid, reliable, and performed well pretty much all of the time, which is the important thing. So OmniOS basically delivered the fileserver environment we wanted.

NetBSD Fundraising 2020 goal

Is it really more than 10 years since we last had an official fundraising drive?

Looking at old TNF financial reports I noticed that we have been doing quite well financially over the last years, with a steady stream of small and medium donations, and most of the time only moderate expenditures. The last fundraising drive back in 2009 was a giant success, and we have lived off it until now.

OpenSSH 8.2 released February 14, 2020

Distrowatch Fury BSD Review

FuryBSD is the most recent addition to the DistroWatch database and provides a live desktop operating system based on FreeBSD. FuryBSD is not entirely different in its goals from NomadBSD, which we discussed recently. I wanted to take this FreeBSD-based project for a test drive and see how it compares to NomadBSD and other desktop-oriented projects in the FreeBSD family.

FuryBSD supplies hybrid ISO/USB images which can be used to run a live desktop. There are two desktop editions currently, both for 64-bit (x86_64) machines: Xfce and KDE Plasma. The Xfce edition is 1.4GB in size and is the flavour I downloaded. The KDE Plasma edition is about 3.0GB in size.

My fresh install of FuryBSD booted to a graphical login screen. From there I could sign into my account, which brings up the Xfce desktop. The installed version of Xfce is the same as the live version, with a few minor changes. Most of the desktop icons have been removed with just the file manager launchers remaining. The Getting Started and System Information icons have been removed. Otherwise the experience is virtually identical to the live media.

FuryBSD uses a theme that is mostly grey and white with creamy yellow folder icons. The application menu launchers tend to have neutral icons, neither particularly bright and detailed or minimal.

LLDB now works on i386

Upstream describes LLDB as a next generation, high-performance debugger. It is built on top of LLVM/Clang toolchain, and features great integration with it. At the moment, it primarily supports debugging C, C++ and ObjC code, and there is interest in extending it to more languages.

In February 2019, I have started working on LLDB, as contracted by the NetBSD Foundation. So far I've been working on reenabling continuous integration, squashing bugs, improving NetBSD core file support, extending NetBSD's ptrace interface to cover more register types and fix compat32 issues, fixing watchpoint and threading support.

The original NetBSD port of LLDB was focused on amd64 only. In January, I have extended it to support i386 executables. This includes both 32-bit builds of LLDB (running natively on i386 kernel or via compat32) and debugging 32-bit programs from 64-bit LLDB.

wpa_supplicant is definitely a lower-class citizen, sorry

wpa_supplicant is definitely a lower-class citizen, sorry.

I increasingly wonder why this stuff matters; transit costs are so much lower than the period when eduroam was setup, and their reliance on 802.11x is super weird in a world where, for the most part
+ entire cities have open wifi in their downtown core
+ edu vs edu+transit split horizon problems have to be solved anyways
+ many universities have parallel open wifi
+ rate limiting / fare-share approaches for the open-net, on unmetered
+ flat-rate solves the problem
+ LTE hotspot off a phone isn't a rip off anymore
+ other open networks exist

essentially no one else feels compelled to do use 802.11x for a so called "semi-open access network", so I think they've lost the plot on friction vs benefit.

(we've held hackathons at EDU campus that are locked down like that, and in every case we've said no way, gotten a wire with open net, and built our own wifi. we will not subject our developers to that extra complexity).

KDE FreeBSD Updates Feb 2020

Some bits and bobs from the KDE FreeBSD team in february 2020. We met at the FreeBSD devsummit before FOSDEM, along with other FreeBSD people. Plans were made, schemes were forged, and Groff the Goat was introduced to some new people.

• The big ticket things:
  • Frameworks are at 5.66
  • Plasma is at 5.17.5 (the beta 5.18 hasn’t been tried)
  • KDE release service has landed 19.12.2 (same day it was released)
• Developer-centric:
  • KDevelop is at 5.5.0
  • KUserfeedback landed its 1.0.0 release
  • CMake is 3.16.3
• Applications:
  • Musescore is at 3.4.2
  • Elisa now part of the KDE release service updates
• Fuure work:
  • KIO-Fuse probably needs extra real-world testing on FreeBSD. I don’t have that kind of mounts (just NFS in /etc/fstab) so I’m not the target audience.
  • KTextEditor is missing .editorconfig support. That can come in with the next frameworks update, when consumers update anyway. Chasing it in an intermediate release is a bit problematic because it does require some rebuilds of consumers.
