OpenSMTPD Is The Mail Server For The Future via @ggpsv https://lobste.rs/s/qmvgke #email #openbsd

#PSA for my #OpenBSD peeps:

I have a simple script called pkg_size that lets you query the size of a package and any dependencies that would need to be installed* without installing it.

* (it totals the sizes that pkg_add -s reports for every mountpoint and converts it to usable SI units, not just bytes)

https://codeberg.org/rldane/scripts/src/branch/main/pkg_size

It has no dependencies outside of base* (I just reworked it to use /bin/ksh instead of bash).

* (Actual dependencies/external binaries called: basename, bc, grep, mktemp, pkg_add, pkg_info, rm, sed, tee)

Example:

$ pkg_size qemu
quirks-7.147 signed on 2025-10-10T23:15:26Z
qemu-10.0.2:capstone-5.0: ok
qemu-10.0.2:libssh-0.11.3: ok
qemu-10.0.2:dtc-1.7.0: ok
qemu-10.0.2:libiscsi-1.20.0: ok
qemu-10.0.2:qemu-ga-10.0.2: ok
qemu-10.0.2:libslirp-4.7.0: ok
qemu-10.0.2: ok
/dev/sd1a on /: 1946 bytes
/dev/sd1h on /usr/local: 882110457 bytes
qemu 841.24 MiB

Usage: pkg_size package1 [ package2 [ package3 ... ] ]

FYI #OpenBSD

We're done with the 7.9 release. The head of the ports tree is now unlocked.
Normal development can continue there.

OK, u9fs for media sharing from unix to #9front is kicking my butt. I am using the "stock" binary from ports on #OpenBSD.

Cpu server / drawterm access are working on #plan9 Glenda has a password and keys and all. I deliberately chose p9sk1 for the keys in factotum to enable legacy protocols since, as far as I can tell, u9fs only knows that.

Added this to /etc/services (from FreeBSD's equivalent):

9pfs 564/tcp #plan 9 file service
9pfs 564/udp #plan 9 file service

Added this to /etc/inetd.conf:

9pfs stream tcp nowait root /usr/local/sbin/u9fs -D -a p9any -l /var/log/u9fs /media

I opened TCP/564 in pf.conf for good measure - tho I think inetd does this? Anyway,

pass out proto tcp to any port 564
pass in proto tcp to any port 564

u9fs.keys is in place on OpenBSD and it has exactly 3 lines only with password/username/host. Can confirm inetd is OK and u9fs process is running.

However, on 9front:

cpu% 9fs 192.168.1.101
post...
srv net!192.168.1.101!9fs: mount failed: unknown user
cpu%

Same result if I run it manually with srv and mount -c

Logs on OpenBSD side for u9fs don't show anything (wish "verbose logging" were actually verbose and logged something..)

What am I missing?!

So glad that I'm running #OpenBSD for my laptops, PC's and #FreeBSD for my servers after reading about copy fail and dirty frag. #RunBSD

Puffy, are we nearly there yet? #OpenBSD 7.9

This #GoToSocial instance has been migrated from #OpenBSD 7.8/arm64 to OpenBSD 7.9/amd64/bhyve.

If you can read this, I didn’t mess up 😅

Nothing wrong with running it on the ODROID, I just wanted it back to a DC.

Most hilarious #OpenBSD bug I've seen in a while: The kernel can panic when pressing the CapsLock key: https://marc.info/?l=openbsd-bugs&m=178186466408482&w=2

Fortunately, true hackers have mapped CapsLock to Control ​

Oh yeah I have a nice Italian beer in my hand and just noticed my #OpenBSD -current desktop has lots of package updates. So now I even have gammastep installed and running nicely on my #MangoWM #Wayland setup. ❤️

Just did a doas sysupgrade -s on my #OpenBSD desktop as i do most days and today when it rebooted it fails to boot. Yet if I just type b followed by enter it then boots correctly ???
I'm at a loss what that last update on the -current` snapshot did ??

kern.version=OpenBSD 7.9-current (GENERIC.MP) #475: Thu May 14 12:34:48 MDT 2026
deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

It won't boot by itself when I normally hit enter at the boot prompt before. Now I enter b and it boots ???

Really strange as on boot I get an error 255 unknown. But some times after many fails it will boot into bsd.sp and others into bsd.mp yet when I type ls at the boot prompt bsd.mp isn't there ??? I think that last snapshot messed something up.

OpenBSD update issues I've had are resolved!

Thank you to everyone who gave me things to try to resolve my #OpenBSD Dell Optiplex 3080 i5 not wanting to boot /bsd but would only boot /bsd.sp and bsd.rd
I tried everything from booting bsd.rd and upgrading to using doas sysupgrade -s but each upgrade failed the same. I even deleted /bsd so it remade it after an upgrade but still the same.
Finally after thinking the next step was to do a fresh install I decided to try rolling back the snapshot to the 1st May. This is not recommended but what had I to lose ?
So i entered doas sysupgrade -sf http://ftp.hostserver.de/archive/2026-05-01-0105/ and guess what ? It only boots into /bsd now and I have all my CPU's back !
Yipee ! 🎉
Now to see if a doas sysupgrade -s does it's stuff and still boots /bsd`

OK there must be a bug somewhere as I rolled back to 1St may snapshot and booted with multicpu kernel no problems.
Then I tried to upgrade to the latest with doas sysupgrade -s and it's back to not booting the /bsd !!!!
Time to rollback to maybe the 14th may and see if that's
OK ??

#RunBSD

I'm in a very good mood now that I have successfully found out what was the issue with my #OpenBSD desktop. I knew it wasn't anything I'd done and space isn't an issue on the partitions either. It wasn't me for once, it was a dodgy OpenBSD snapshot! 😁

I had no idea there's a port of HAMMER2 for #OpenBSD !

(from @bpl )
Maybe one day gefs will get ported to OpenBSD - https://marc.info/?l=openbsd-misc&m=175109777313355&w=2.

HAMMER2 seems to be unofficially available - https://github.com/kusumi/openbsd_hammer2, but not sure if anyone was brave enough to use it.

As I lost sponsoring (due to a whole location shutdown) for my @BoxyBSD & @BoxedTux in North America, I’m looking for sponsors in US and Canada.

The requirements are pretty low:

NO IPv4
min. IPv6 /48 subnet routed
Network (ARIN/RIPE/…) should be personalized (netname, abuse,..)
Optionally: BYOIP
ARPA delegation for the net to my nameservers
min. 2x 500G disk space (SATA SSD or better)
min. 48G memory per node
bandwidth doesn’t really matter (100Mbit is fine)
Remote MGMT to systems

Sponsors are being listed on #BoxyBSD and #BoxedTux on the sponsoring page and announced on LinkedIn, Fediverse and X as new sponsors.

Finally have the excellent terminal browser #chawan running in OpenBSD!

IIRC, #nim wasn't available for #OpenBSD before? Or was I just dreaming that? XD

OK then. I have just dowmloaded the #OpenBSD 7.9 img and done a fresh install on my desktop machine wiping everything from the past out. It boot perfectly fine on release so I proceeded to switch to my usual -current as per the docs and it ran through the upgrade without issue.
Can you guess what happened when it tried to boot the /bsd kernel on this intel i5 machine ?
That's right it failed with the same error 255 that the bugs mailinglist told me was an issue I had probably caused so go reinstall. I knew it wasn't me as it was extremely strange how I could rollback to the 14th May or earlier with out any issues it always booted the /bsd ( MP ) kernel but after the 14th May it would not but would boot the copy I had of the last working /bsd renamed /bsd.xyz
I'm too tired to go back to the misc or bugs mailinglists to be told it's me. I know I wouldn't have got that response from the #FreeBSD devs so maybe it is a sign from above ?

I love #OpenBSD (and all the BSDs, heck all the #FOSS OSes, they're all amazing), but y'all, this is a bit sad:

I know about pkg_locate, and I use it by default, honestly, but "that's not in base!" ;)

My network speed is a bit slow, but not that slow.

Well this is a nice surprise, #HaikuOS boots fast and even #WiFi and multi-finger touchpad scrolling work out of box on my #ThinkPad T470s. It is dual booting alongside #FreeBSD and #OpenBSD on the same hard disk. I can browser web sites fine. Only thing is sometimes touchpad becomes laggy and I have to plugin a mouse. It is very a fascinating system, I will keep it running for now and explore more about it.
