I love how easy it is to be a part of FreeBSD:

Open a account at

Go to and find your outdated port (or port without maintainer (

Update port (makefile) open a bugreport add your diff and that's it...or ask to take additionally maintainership of that port.

I was introduced to FreeBSD (v3.3) in the late 90s by /user?id=gjvc. I bought the CD set and the FreeBSD Handbook in paperback format from The FreeBSD Mall.

I was too young to appreciate it back then, but now in my mid-40s I find myself hankering back to those early days for me. It's a shame that some cloud providers like DigitalOcean and Hetzner have dropped native support for FreeBSD as base operating systems for their VPSes. I think this release will be the turning point for me getting back into FreeBSD after too many years away.

Thanks to the FreeBSD release team!

jbverschoor7 months ago

Yup.. FreeBSD was awesome becausethe FreeBSD handbook has always been top notch. It covers everything you need to install and administer FreeBSD + many of its packages

BSDobelix7 months ago

Talking about hetzner, they write you an image on a USB-Stick and put it in your Server (at no cost). Since it's a real server i don't need any "native" support from them. Otherwise Oracle-Cloud or Vultr.

But you are right, it's sad that hetzner dropped the "webinstall no hands-on" support.

pjmlp7 months ago

Azure still offers them,

Once I opened a ticket to complain that it is listed under "Linux custom images", however the documentation team decided my complaint was withouth reasoning(!).

whartung7 months ago

My early FreeBSD moment was when I had a cable modem, and you were able to download one or two boot floppies. After you booted them up, you could install the entire OS from the network. No CD needed.

I assume it just downloaded everything straight from FTP servers.

ioman7 months ago

Oh, look who has a fancy cable modem! Back in my day, we had to do it with 14.4 kbaud modems (really) after walking to school, uphill both ways in the snow (not really).

I would guess you had a 14.4 kbps modem operating on 9600 baud.

I run freebsd on a hetzner cloud vps, don’t remember how exactly I did it but I think I uploaded the install medium to the server console. Wasn’t too much hassle iirc.

The problem with FreeBSD is that it couldn't keep up. No containers or VMs (jails and their homegrown HV don't cut it), fewer drivers, etc. It's great for some server use cases but I just couldn't do my work in FreeBSD. I did like it though, the docs and community are great.

shrubble7 months ago

They have had jails for 20+ years at this point. I would consider FreeBSD jails and containers on Linux equivalent at this point with overall the FreeBSD jails being better to manage if you do some scripting. The bhyve hypervisor, I haven't played with enough to form an opinion on.

0xNotMyAccount7 months ago

Unless of course you're trying to sell to an enterprise who's core competency isn't computational, and has limited capacity to manage new operating systems in the fleet. Lots of big orgs can only support so many things. It seems odd until you realize they're not running your service. they're running thousands of services across multiple geographic regions with hundreds of thousands of corporate users. And all the upgrade paths that go with this whole thing, and the external facing integrations, etc, etc.

So, sure, if you've got a stand-alone B2C service that's making money today, enjoy your FreeBSD, SUSE, whatever. But if you're clients include big banks, chunks of governments, etc, think really hard about going off the reservation.

From the release notes, it appears this may be the last release with i386 / 32-bit Intel x86 (as well as 32-bit armv6 and PowerPC) support.

“FreeBSD 15.0 is not expected to include support for 32-bit platforms other than armv7. The armv6, i386, and powerpc platforms are deprecated and will be removed. 64-bit systems will still be able to run older 32-bit binaries.“


cperciva7 months ago

Probably 14.3 will be the last release with i386. But yes, 14.x will be the last major branch with i386.

csdreamer77 months ago

Surprised that armv7 will be getting 32bit support but not x86. I know arm is huge, but it's platform support is also fragmented compared to an x86 box. Can anyone share some more info on this?

Also surprised they are cutting Power. That is one of the 4 platforms RHEL supports.

dragontamer7 months ago

There's an industrial computer chip using ARM9 (aka: ARMv5 !!!!), let alone ARMv7.

This was released in the year 2020, for example, the latest Atmel SAM Microprocessor. While ARM9 / ARMv5 is abnormally out-of-date (lol Nintendo DS was ARMv6), its still getting new chips even today.

ARMv7, consisting of Cortex-A5, A7, and similar chips, is also similarly widespread today. I don't know how much FreeBSD support there is but I can think of multiple chips that have been made in the past 5 years that are still 32-bit ARMv7.

In an embedded world that still buys 8-bit computers, 32-bit is a luxury and 64-bit is just too much.


I'm only familiar with these chips from a Linux perspective however. But I have to imagine that some FreeBSD fanboi is hard at work porting FreeBSD to them!

EDIT: Lets see....

Oh snap, Xilinx Zynq7 family. Yeah, that will do it. That's an extremely common chip (FPGA + ARMv7 / Cortex-A9).

laxd7 months ago

> ... some FreeBSD fanboi is hard at work porting ...

Or developers.

dragontamer7 months ago

> Also surprised they are cutting Power. That is one of the 4 platforms RHEL supports.

They're cutting 32-bit Powerpc. It looks like powerpc64le support remains in FreeBSD14.

cperciva7 months ago

Aside from 32-bit arm being used in more small embedded systems, I think it has 64-bit time_t. One of the reasons for killing of i386 is the Y2038 issue.

csdreamer77 months ago

Ah, makes sense. That is a real issue for Linux and how distros will handle that. Besides cutting 32 bit userland support.

I think a lot of the work for serving 800Gbps of TLS encrypted traffic from Netflix landed on FreeBSD 14.

Cant wait to see if they are doing 1600Gbps.

crest7 months ago

IIRC the limit right now is per CPU socket memory bandwidth and inter-socket bandwidth. There just isn't enough bandwidth available to treat dual socket Xeon or EPYC systems as a single node ans the networks colocating their appliances aren't able to steer connections to the NICs in the same NUMA domain as the NVMe storage holding the data users want.

ksec7 months ago

Probably need to dig up those info, because I keep remembering they were on Dual Socket 64core Zen 3 with PCI-e 4 and DDR 4. The 128Core Zen4C with more memory channel and DDR5 should be able to push further.

> FreeBSD supports up to 1024 cores on the amd64 and arm64 platforms.

Sounds pretty future proofed unless I'm missing a x86 processor out there that does this

krylon7 months ago

If you combine multiple CPU sockets, you could get there. EPYC, IIRC, supports up to 64 cores per chip, so if you build a machine with 16 sockets, you get 1024 cores. To my knowledge, no such machine exists today, but HPE offers (or used to, anyway) a machine with 32 Xeon chips, so its core count could well reach several hundred. (I may or may not be drooling at the thought.)

It's a lot easier to build such a machine if you have something to run on it, I suppose.

> up to 1024

Curious where this (rather large, yet still seemingly arbitrary) limit comes from.

throw0101a7 months ago

> Curious where this (rather large, yet still seemingly arbitrary) limit comes from.

It is Good Enough for now, while keeping various pre-allocated, statically created structures with-in reasonable size limits:

> Global and allocated arrays sized by MAXCPU result in excessive bloat on systems with lower core counts. In addition, some code used u_char (8 bits) to hold a CPU index, which is not valid if MAXCPU is greater than 256.

> A number of recent commits addressed these sorts of issues, including at least: […]



> The SMP system now supports up to 1024 cores on amd64 and arm64. Many kernel CPU sets are now dynamically allocated to avoid consuming excessive memory. The kernel cpuset ABI has been updated to support the higher limit. 76887e84be97[1] d1639e43c589[2] 9051987e40c5[3] e0c6e8910898[4] (Sponsored by The FreeBSD Foundation)


toast07 months ago

Gotta have some limit, 4x the current limit of 256 seems reasonableish. Dual socket Epyc 9654 is 96 cores * 2 threads / core * 2 sockets = 384 threads. Intel says their Xeon Platinum 8490H can live on an 8 socket board[1], if you can find one (SuperMicro has one, no price listed [2]; not sure if this is really an 8 socket system, or if it's 4x dual-socket nodes in one chassis?); 60 * 2 * 8 = 960, so that's within the limit, and 8 socket boards are pretty difficult to find.



vluft7 months ago

9754 is 128/256 now, so 256/512 for that.

That supermicro system is 8-way; it's 4 dual-socket motherboards but they're one system, hooked together by backplane boards. You can price supermicro's complete-system-only stuff (all of it now, alas) out on thinkmate or similar sites, but a minimal config (and you'd never buy that for a minimal config) hits around $60k.

crest7 months ago

Bitmaps for logical CPU cores and certain lock-free algorithms don't scale well to arbitrary high CPU counts e.g. reclaiming resources once in a while is O(n^2) or worse or the size of the lock structure is linear to the maximum number of cores etc.

The relevant parts of the ABI have been future proofed to allow raising the kernel CPU core count limit without breaking the syscall interface for systems with less cores than the existing limit.

The_Colonel7 months ago

"supports up to" doesn't have to mean "works well/optimally with".

samtheprogram7 months ago

I tried out FreeBSD and loved it, between the documentation, cohesion, and the ports system.

Unfortunately, I need Docker for work on a few different projects -- one for Supabase migrations, and another project that's orchestrated (in development too) via docker-compose.

Highly recommend it otherwise.

ptx7 months ago

You could run Docker in a Linux VM, which is what Docker Desktop does anyway. FreeBSD has Bhyve for this.

magicalhippo7 months ago

I do this and the only thing that sucks is that network speed is limited. Between host and guest I only get about 1.5Gpbs on a Threadripper 1950X.

NIC pass-through should work though, I already got NVMe pass-through working, so if I had a spare PCIe slot I'd do that with a 10G adapter.

gigatexal7 months ago

Having to use a VM for docker is no different than what MacOS users have to do and then at that point why not just use a Mac.

globular-toast7 months ago

Why not use a Mac for my ZFS-based NAS? Is that your question?

dehrmann7 months ago

Do you even need a VM? FreeBSD has linux binary compatibility.

wut427 months ago

Docker is a container based tech. the binary compatibility won't help.

dehrmann7 months ago

Binary compatibility is the key part. You can ignore a lot of what cgroups and namespaces give you and containers will still "work" (but without the insecure sandbox). Without the binary, you're out of luck.

waynesonfire7 months ago

I have a similar requirement and will be doing exactly this.

inferiorhuman7 months ago

I've been running FreeBSD for homelab stuff for years now and the documentation is a huge pain point IMO. The handbook is okay, but beyond that it's pretty poor.

E.g. every single major upgrade in recent memory has shat the bed. There's always a new reason, at one point it's because I rolled past the 3AM deadline and the periodic scripts absolutely fucked freebsd-update. So this time around I thought it'd be nice to script the 13.x install so I'd have a nice repeatable process.

Except the documentation around unattended installs still references sysinstall (which was replaced eons ago) in some parts. After quite a lot of digging I realized the automation story is "roll your own ISO". Nothing that even comes close to kickstart or quickstart in Linux land (geee no wonder AWS adoption is fairly low).

So I dug into some stuff that would've made automated installs from a stock ISO easier, got a proof of concept working and fired off an email to one of the names on the current installer (which is still missing features from sysinstall!). And that's where the story ends. I'm ready to get off of this train, and were it not for ZFS I would've already bailed.

Don't get me started on the ports tree.

I would not run FreeBSD in a production environment without a good reason. If you're already tied to docker that's a great reason to stay with Linux.

bionsystem7 months ago

You could try SmartOS for native ZFS support + virtualization built in (including linux containers) + pain free upgrades. Not a BSD but shares a decent amount of values (and code). It's a candidate for my home server and so far I love it.

FreeBSD was another candidate but just skimming through the docs, what's easy on other systems looks painful there. Want to start a VM ? Here is a set of commands, different for every guest OS, with a bunch of unexplained options...

doublerabbit7 months ago

> If you're already tied to docker that's a great reason to stay with Linux.

I'd say the opposite. A great reason to run from Linux.

inferiorhuman7 months ago

I'm not much of a docker fan but there are benefits to the docker ecosystem which you would lose completely by switching.

adamddev17 months ago

I want to love FreeBSD, but there are some things I wished were easier. Like getting the firewall pf set up. When I install Debian with ufw I get a really nice starting ruleset that works well with IPv6 and good ICMP filtering etc. With FreeBSD I was confused for awhile about how to get IPv6 working with (the very powerful) pf, which you have to write a config file completely from scratch for. I was left with a lot of suggestions and snippets but struggling to dig through the man pages and set all the complex rules for which types of ICMP messages to filter, etc. I wish there was an easier way to get going with the firewall with a good ready-made pf.conf file for a web server that works well with IPv6. Yes the power and easy customability of pf is great. But for many users who aren't network experts, some nice, accepted starting templates would be great.

gerdesj7 months ago

"Like getting the firewall pf set up"

pfSense 2.7.0 is FreeBSD 14 based already and 2.7.1 was released todayish. You could try tearing their scripts apart to see what's what but bear in mind that pfSense is designed to be a router/firewall not a host based firewall, which sounds like what you really want.

It sounds like you want ufw or firewalld for FreeBSD. No idea if it exists and I am well passed DIY - I had custom scripts for ipfw, ipchains and iptables on Linux and then gave up. I don't use FreeBSD on the desktop but if I did ...

or keep it simple:

You mention a web server. I suggest you keep the host firewall simple, this is in pseudo code:

  allow ssh from LAN
  allow monitoring_ip to monitoring_ports
  drop blocklist_ips to ALL
  allow https from ALL to webserver_ip
  deny all
Your external router should keep most things out, the host firewall is a last resort. If you have a flat LAN, then this will keep your TV out etc. I have seen a TV port scan my home network, multiple times.

If you can, consider deploying multiple VLANs. This does raise the technical bar somewhat! Host firewalls are just as good for small setups. Decide on what your security requirements really are and work on from there. I will grant you that is quite tricky for the uninitiated but keep asking questions and ducking the inevitable "RTFM" style answers from entitled numbskulls and you will get there.

Good luck 8)

inferiorhuman7 months ago

I'd caution you from pulling examples from other operating systems. I started dicking around with writing an interactive pf shell earlier this year (which somehow got me to where I am today writing an xpath parser in rust) and quickly learned that a.) the documentation is often pretty sparse especially for the API and b.) pf is all over the place (Solaris, MacOS, FreeBSD, OpenBSD, DragonFly, pfSense, etc.) but each version has some pretty significant differences.

Every single one (including pfSense) has their own variant. From what I can tell FreeBSD's taken bigger steps to sync up with OpenBSD than the rest, certainly bigger than pfSense.

adamddev17 months ago

Thanks, I used that Digital Ocean tutorial, but it doesn't get into the ICMP filtering enough, which you need for IPv6. And the pseudo code you shared is nice, but again, IPv6 will not work with that. ufw comes with a base ruleset with like 100ish lines of complex ICMP filtering. It's difficult/impossible to expect everyone to be able to write something like that from scratch in a syntax like pf. I just wish there was a complete, good template out there, but I haven't found anything.

gerdesj7 months ago

ICMPv6 was designed to be a bit more robust than the v4 variant and I believe it is considered OK to allow all.

I have six WANs at work - four FTTC 80/20Mbs-1, a 1Gbs-1 leased line and a 1000/300Mbs-1 FTTP job. All have IPv6 apart from the FTTP. I only push through the leased line /48 to inside but I do experiments with the IPv6 on the others. I have a /56 IPv6 at home too, for at least 10 years.

I have allowed all ICMPv6 on two out of the four FTTC lines and not noticed much difference. The other two only allow "useful" ICMP, where useful is similar to this:

Let your external router do the hard work. Your web server on the inside should allow all ICMPv6 in both directions. Just because it has a globally routeable IPv6 address(es) it is not on the outside. Your webserver's firewall is a host one, not an external router one. There is a big difference. Your webserver might be configured to think about itself only and your router's firewalling might consider everything from a high level.

I don't think you need a complicated policy on your webserver but one that stops you accidentally exposing, say, a MariaDB/MySQL to the outside world because you bind it to all interfaces instead of just ::1.

adamddev17 months ago

> Just because it has a globally routeable IPv6 address(es) it is not on the outside. Your webserver's firewall is a host one, not an external router one.

Interesting, so with my VPS on Vultr, there'd be an external firewall that takes care of the messier filtering?

BSDobelix7 months ago

Well there are some examples:

But yeah that pf.conf could be expanded allot, but there are many source to cobble a conf together. My conf is massive but 99.9% commented out so i have my "template" for nearly everything, from mail to web to blacklistd etc.

torstenvl7 months ago

Have you considered putting your conf on GitHub?

One of my most popular repos (which isn't saying a lot) is a single config file.

BSDobelix7 months ago

Let me think about's really massive and has comments like "*uck that if scrub on" or "set aggressive -> emailservers try and try again" and those are the best understandable comments believe me.

All is mixed from highly reliable and fast connections to dial-up "industry" stuff.

However that would be a good motivation to clean that monster up...hmmm

tambourine_man7 months ago

Do it! :)

adamddev17 months ago

Those are great but I don't see anything for a web server. Would just love a webserver that works with IPv6 and handles all the ICMP filtering like ufw does out of the box.

dehrmann7 months ago

It's been forever since I really played with firewalls, but I remember pf being much more thought-out than iptables.

waynesonfire7 months ago

I'm a fairly new FreeBSD user and this will be one of my first major upgrade. What should I be aware of when performing major upgrades? On Linux, I would avoid it and just start from a clean system. Curious what more experienced users thoughts are.

bell-cot7 months ago

With care - and upgrading a test system or two first to re-familiarize myself - it's worked fine for me. Two tips:

- Understand `gpart bootcode` (or equivalents), and be really sure that your low-level bootcode gets upgraded.

- If you're running zfs, `zpool checkpoint` can give you a way to rewind the entire state of the pool to a prior point. Used with some care, it can be extremely useful. Or just reassuring, as your "Plan B".

waynesonfire7 months ago

This is interesting. I was just playing around with a VM that had mirrored ZFS root and I wanted to test if I could boot from either mirror--it requires a bit of hand-holding since /etc/fstab seems to hard-code the gpt label of the boot device making it difficult to boot from the mirror without first changing that reference.

I didn't realize this and went down a rabbit hole of trying to recreate boot partitions which I found interesting.

With that said, I'm curious whether the upgrade procedure updates the bootcode on both drives in the mirror.


Slight tangent. The reason for playing around on the VM was that when I installed FreeBSD, I selected the zfs root auto-fs feature. It created a zfs partition that spanned the entire disk which I later decided that I didn't want. My goal was to shrink the zroot, and I was able to accomplish that using zfs send / receive and re-creating the partition withe the desired size. Fun exercise.

I need to revisit the installer to see if I'm able to provide any parameters to tune the size of the zroot. I really didn't want to create the filesystems manually from the installer shell.

rwky7 months ago

I've had some issues with the opensmtpd port when upgrading from 13 to 14 which is probably due to the openssl upgrade. Apart from that the upgrade process tends to be pretty simple the updater warns you of any potential problems. As with any upgrade take a backup first so you can restore to 13 if you need to.

adamddev17 months ago

I just upgraded to FreeBSD 14 from 13 and it was fairly clean. It asks you to evaluate diffs for a few config file changes. The only issue I had was that sudo was uninstalled for some reason so I had to go back to my server console, go in as root and re-install sudo.

inferiorhuman7 months ago

If you're talking about a home lab or workstation environment I would 100% back everything up and start from a clean system. Go back to FreeBSD 9 or 10, in-place upgrades have consistently bit me in the ass. Installer getting wedged, problems upgrading the boot loader, disk labels, freebsd-update getting wedged, you name it.

If you're talking about a production environment, ideally your machines are more-or-less immutable anyways in which case you wouldn't be upgrading in place anyhow.

olavgg7 months ago

Compared to RHEL, CentOS, FreeBSD upgrading is a breeze. Debian is easiest. I have done like 100 different upgrades of FreeBSD and most has been without any issues.

If you use Jails, you have to upgrade them also, there are guides for this.

- turning all internet facing services (except ssh) off, by default. OpenBSD does this.

- move all non-core things out of the base, like sendmail (now DMA, what a nice import from DFly btw)

- the base should only have one way to do things (don’t have 3 different firewalls in base like today)

- better defaults,

- something like io-uring, (async-sendfile is similar but that’s only for sendfile)

Thank you again for an amazing OS.

EDIT: I updated the first bullet of C for more clarity.

I think people would be rightfully upset if syslogd, cron, and getty weren't started by default. moused and a mailer daemon I get not wanting to start. What else starts by default that you don't want?

I dunno about ipf; but ipfw and pf don't have complete overlap --- I need to use both to run my network how I want to (pfsync has no equivalent in ipfw, ipfw pipe/queue/sched doesn't have an equivalent in pf)

Regarding the first bullet, thanks. I just updated my post for more clarity.

I meant internet facing services (e.g. not referring to cron, etc).

Well still, what's running out of the box other than a mail daemon (which I agree with you about), and maybe sshd? (I think it asks you during setup for that one, but I'm not sure anymore)

Colin is extremely well known on HN. Famously he was a center of a.... peculiar exchange where his skills were questioned, and he had the comeback of a lifetime:

What's the Putnam if I may ask? It sounds like an academic competition? Google didn't really enlighten me.

I know what it's like though, I won a big prize in school. Not saying it compares to yours but I stood out too. Didn't really help me become more popular though or boost my self confidence. But it was nice to give a middle finger to all the bullies for once.

Ah ok a maths prize, cool! My prize was more general science. I'm very good at sciences but I have a mental blind spot for maths, I can understand really complex abstract problems but only if I can imagine them, explaining them with math makes it more confusing. It's weird :) In fact I was super surprised I won it because I screwed up the math part as expected.

Nice about the scholarship! I didn't get one but we don't really need them in the Netherlands. All universities cost a minimal standard fee only.

I wish more random guys gave 2^18 dollars to open source.
