Hello everyone!

I want to order some stickers. Do you know a website which has high resolution pictures, or svgs?

I want pictures for #FreeBSD, #DeltaChat, #WebXDC, #OpenVoiceOS, #Alpine, #Emacs, #CommonLisp, #SLIME and #Luanti(#Minetest).

The website I want to order from already has got stickers for other things I want.

Boosts appreciated.

More generally: #kqueue still has several ragged edges, compared to poll/select.

Every little helps in order to fill in all of these gaps.

I submitted my #kqueue support for sound(4) on #FreeBSD. I hope we will polish it soon enough. reviews.freebsd.org/D53029

Looking at the *at family of functions and I just realized that I viewed them as part of the capsicum security framework and not as part of allowing a threaded program to access relative paths from each thread's own working directory.

This explains why absolute paths are allowed and ignores the directory fd.

FreeBSD's openat man page explains this.

Running 14.3-STABLE right now. Intel iwlwifi driver with an Intel AX210 card giving me full 250/40 Mbps (the maximum of my DSL line) via WiFi :)

Random connection issues, that I had with -RELEASE are solved in the current -STABLE 🙂

5Ghz, 802.11ac with 80Mhz wide channel...

We're making fast progress with FreeBSD on the modern desktop 🙂

Been following the BSD conferences for a while and have not yet had the chance to attend one. But what i have noticed from all the videos and photo's published on social media is that it seems to be a male ( I'm going to include NB folk here too ) dominated event ? Maybe I'm wrong and it's just how the media published distorts the reality ? Apologies if I have offended anyone it certainly isn't my intention.

Anyone know how to determine wear on an NVMe drive on #FreeBSD?

Suggestin smartctl is not helpful here. It just doesn't do it.

I looked at nvmecontrol and could not find help there either.

Anyone running #FreeBSD on one of Oracle's free tier?

I tried once, gave up. I don't recall the block.

The September 9th, 2025 Jail/Zones Production User Call is up:

We discussed Eurobhyvecon, Jail Descriptors, Capsicum vs. Pledge, the WITHOUT_JAIL build option, the Yggdrasil overlay network IPv6 routing scheme, podman, PkgBase, Netgraph vs. bridge vs. aliased networking performance, rctl and cpu set, the Nitro init system and process supervisor, and much more!

#illumos #omnios is absolutely incredible. The system is very well designed IMO, I had already experienced the more cohesively designed #BSD but here it feels a bit *more* (although quite similar in some aspects to #freebsd of course).

Linux feels like a duct-taped amalgamation of random ideas, don't get me wrong I love Linux and all it represents, but it's a system that has been grown in any direction.

With Illumos instead it feels like you have orthogonal powerful building blocks you can compose into something greater than the sum of its parts. #zfs #dtrace #zones #crossbow it all works beautifully, both on their own and together.

After seeing how virtualized networking can be done in solaris, the docker networking stack feels so sad in comparison.

So far I'm very impressed.

In #FreeBSD you can modularize your config with separate files in /etc/rc.conf.d/ except... for networking? The ifconfig / dhclient settings don't work unless they're in the regular /etc/rc.conf

I need to file a bug about this I guess

First steps in the BSD world!

1) OpenBSD on VPS (Amsterdam)
2) FreeBSD on Raspberry Pi 4 (home)

I'm running a Wireguard connection between the two.

Next step is setting up relayd on the VPS to point at services on the Raspberry Pi server.

Anyone using net-mgmt/net-snmp on #FreeBSD with AES-256-C support? Or indeed, anything more than plain AES?

How can I confirm support is compiled in?

I ask because I can use these on snmpwalk

-x AES
-x AES128

but not

-x AES193
-x AES256
-x AES256C

They give an error such as:

Invalid privacy protocol specified after -3x flag: AES193

I ask because some newer gear uses AES-256 by default.

This is a vuxml node from #FreeBSD security/vuxml port.

<vuln vid="44101b31-8ffd-11e7-b5af-a4badb2f4699">
<cancelled/>
</vuln>

I'm trying to detect cancelled vid.

I'm using perl's XML::DOM::PARSER

I tried:

my $cancelled = $node->getAttributeNode('cancelled');

and

my $cancelled = $node->setNodeValue('cancelled');

But that comes back as: Use of uninitialized value $cancelled

I don't know what functions to call to detect a cancelled node.

#FreeBSD recommendations for #monitoring #alerting #observability sought. I have a much loved collectd + riemann that needs an upgrade.

Target is about 10 servers and 200 jails.

No apache2 /php, nagios or clones thereof please. I don’t have these in my stack today, and my expertise in managing them is about 20 years out of date. I prefer to avoid JVM stuff but I’m not violently against it.

Doesn’t have to be in ports yet ( like sensu.io/ server) if it’s in a friendly language.

in theory, code review is a great idea because it means at least two people have seen code before it lands, which prevents silly errors and mistake that anyone can make.

in practice, code review in #FreeBSD means that you can't commit anything until your code has been reviewed by someone who works for Klara, Netgate, or Netflix.

because code review is unrewarding and time consuming, only people who are paid to do it will do it, which means all code is gated through a corporate representitive.

this is not really an ideal situation.

I don't know if anybody noticed #ZeroFS yet, but it seems there is a completely user space-implementation of #NFS and #blockstorage on top of #S3 #objectstorage: github.com/Barre/zerofs

Including a demo running #ZFS on top of it which essentially allows geo-redundant ZFS volumes: asciinema.org/a/728234 & github.com/Barre/zerofs?tab=re…

I don't see no #FreeBSD port yet, but if that really works it would be absolutely awesome.

On FreeBSD if you want to list only the packages you explicitly specified to install (excluding packages that were pulled in as dependencies), run:

$ pkg prime-list

This can be useful for duplicating the list of packages installed on another machine.

new FreeBSD bridge(4) review: “bridge: add defvlanfilter and defuntagged options" reviews.freebsd.org/D51176

this lets you do:

$ ifconfig bridge0 defvlanfilter defuntagged 1

... which causes all newly-added member interfaces to have VLAN filtering enabled and be in VLAN 1 (only).

then your VM/jail management tools (vm-bhyve, …) can continue using 'ifconfig addm' to add bridge members and don't need to know about VLAN configuration.

fun fact: this is how most people expect bridge(4) to work already, but it is not how bridge works already! in reality, all bridge members have access to all VLANs by default, and before VLAN filtering there was no way to restrict this at all.

i wonder how many systems accidentally allow jails/VMs to access their host management VLAN because of this?

for that reason (among others) i'd like to make this the default configuration of bridge(4) in a future version... 15.0 may be too early, though. but we should document this better.

As I start to explore the ZFS filesystem in more detail on FreeBSD, this post on snapshot basics is very helpful:

Linux is 2nd class citizen in ZFS world. No ZFS Boot Environments - no GRUB for modern ZFS pools - no distro with installer support for ZFS on root and BE setup.

Why then #FreeBSD would downgrade to Linux level on ANY level?

Its insane for me.

32 years ago today, #FreeBSD was announced for the first time. I haven't tried this OS yet but I can assure you that I will because I want Quark, my OpenSource reverse proxy, to be supported on other Unix systems than Linux.

For this special occasion, I drew this little picture on #Krita 🙂
