This morning I needed a simple S3-compatible object store to test something. I did some quick searches to see what was handy and useful in that space right now, eventually found SeaweedFS, and it did exactly what I needed ...
And *then* I opened today's issue of The Crux by @daedalus which would have given me this exact answer immediately and saved me a lot of time.
Don't repeat my mistake. Always read The Crux with your morning coffee before you attempt any other work.

Ah! The nginx updates fixing CVE-2026-42945 have arrived for my RHEL (Red Hat Enterprise Linux) machines. So. `dnf update` and `reboot` to get them installed. Safe again, for the moment :)

Just to keep stuff correct. Copyfail and DirtyFrag CVEs are fixed in almost all Linux distribution kernels. As far as I can see there was no widespread damage. The nginx CVE needs a non-default config to be exploitable. So update your machines and relax. And dear tech journalists — please do a bit more work to put things in context instead of shouting FIRE from the rooftops whenever you see smoke. It could also be a hot pile of sh*t that causes that smoke ;)

Oh hey. Today is Thursday, and you know what they say about Friday!
Don't wait to do it tomorrow when you can procrastinate even more and do it next week. 😄

After a year of running Nextcloud storage [1] at Hetzner, I noticed that I hardly use it. Sure, it's nice to have 1TB of storage at around €5/mo, but I simply haven't found a good way to make it part of my digital life. I will experiment with running my own Garage based S3 compatible storage [2] on one of my VPS machines instead (yes, my VPSs have unlimited network traffic).

Csináltam egy merészet.
Van egy Lenovo Yoga 11e tablet PC-m. De, Linux alatt egyszerűen sosem működött a tablet funkció.
Hat éve van nálam, de együtt tudtam ezzel élni, mert igazából nekem egy valóban kis laptop kellett utazásokhoz, ha ügyet kellett oldanom alapon.
Sosem használtam ki tabletként. Még Windows alatt sem. (Igaz, Windowst csak és kizárólag az ősöreg, de LifeTime Garmin Nuvi GPS-em frissítéséhez használok egyedül, mert nincs kedvem kerülő utat keresni rá.)
De, úgy voltam vele, hogy ha már van mindenféle CLI-s AI agent, akkor teszek egy próbát azzal is.
Oda adtam a Claude AI CLI agentjének sudo joggal együtt, hogy... oldja meg, ha tudja.
Dolgozik bőszen. És, igazából nem csak azért nem félek, hogy elront valamit, mert nincs semmi szenzitív azon a gépen és pikk-pakk újra telepítem és kész.
De, azért sem, mert egyszerűen egy netes keresést nem tud megcsinálni anélkül, hogy minden oldalra külön rá ne kérdezne, hogy engem-e....és ugyanez minden lépésnél itt is. Egyszerűen nem tudok normálisan gépelni, mert a másik monitoron az ssh-ban folyamatosna nyomkodnom kell az entert a jóváhagyások miatt.
Kíváncsi leszek, mi lesz a vége!

Now that the updated kernels that fix #CopyFail have been published by Red Hat, I did `grubby --update-kernel=ALL --remove-args='initcall_blacklist=algif_aead_init'` to remove the mitigation, followed by a round of `dnf update` and `reboot` on all my machines running RHEL (Red Hat Enterprise Linux) and can now make a hot cocoa before I can go to sleep, knowing all is well. Thank you, Kernel engineers for keeping us safe!
-
I did this on my exposed servers, even though I think the actual risk for me and my machines is low as an exploit needs local user access. I verified that none of the services and containers I run on my machines caused problems after this change. Everything kept on working as before, so all is safe.
I'm keeping an eye on https://access.redhat.com/security/cve/cve-2026-31431 for updates.
-
To mitigate the #CopyFail #CVE_2026_31431 risk on machines running Red Hat Enterprise Linux 8,9 or 10 (7 and below are not affected) until the kernel updates are available, you can issue
# grubby --update-kernel=ALL --args="initcall_blacklist=algif_aead_init"
as root, which will block calls to the compromised function. You then need to reboot the machine for the change to become active.

Friday is `dnf update` and `reboot` day for the machines in my homelab and the servers I run on the internet. My machines all run Red Hat Enterprise Linux, so I know I am protected against any new threat that comes with a lot of media fanfare, because we at Red Hat stoically fix things and make the updates available. So as on every Friday, I can relax and enjoy the weekend :)

🚨 Informe de estado: Planeta Hogar.
Como buen #SysAdmin, mi entorno de producción más hostil es mi propia casa. He documentado esta entropía doméstica: macetas que bloquean el Wi-Fi, perros auditores de Capa 1 y copias de seguridad imposibles. 🐶🪴

Another painless update for #Forgejo. My instance is now running 15.0.0 as rootless container. Thank you, team and community!

But no problem. Three commands and update done.

As if they were waiting for me to finish my Friday cycle, #Forgejo puts out a new release right after I'm done ;) https://floss.social/@forgejo/116380645770940093

All updates done, all reboots successful. Also updated my three instances of the forgejo-runner to 12.8.2 and can now relax.

Yesterday I updated the immich containers, today is the usual `dnf update`and `reboot` cycle on my 9 servers running Red Hat Enterprise Linux. The weekend will be used to finally move the stepca Certificate Authority and I will also swap in new batteries on my iPod classic 6th gen and 3rd gen nano.

🚨 Stromausfall am Morgen, Admin-Frust am Abend:
Nach 10 Stunden Schrauben, Fluchen und Kaffee ist mein #Homelab endlich wieder bei 💯%.Der Crash:
⚡️ 2 #Proxmox-Nodes mit zerschossenen LVM-RAIDs
💥 Backup-Server wollte partout nicht startenDie Rettung:
🛠️ Cluster per Hand neu hochgezogen
📦 alle LXC-Container aus Backups wieder eingespieltHat Nerven gekostet, aber: mein Backup-Konzept hat den Ernstfall überlebt. ✅
Lesson learned: Stromausfälle sind der härteste Integrationstest. Ich brauche dringend eine #USV -
Quarter 1 datacenter maintenance window. This time I'm migrating our primary NetApp cluster to a new pair of cluster interconnect switches.
Wish me luck :)

Nachdem nun alle AD‘s heute wieder laufen, kommt gleich die nächste Folge der nicht enden wollenden Serie: "Wie treiben wir Stefan zur Weißglut". Heutiges Thema: Plötzliche und unerklärliche Paketverluste bei IPsec-Tunneln über Weitverkehrsnetze.
Diese Woche ist echt der Wurm drin, es ist zum rückwärts essen.

Today I want to thank the teams and communities behind
- #Forgejo [1]
- #Garage [2]
- #Kopia [3]for delivering (major) updates of their software (which if course is Open Source) that consistently JustWork™ in my experience, making the update process simple, reliable and, yes, fun! I know how hard that is and I tip my hat to all of you and many other projects that do the same.

TIL (Today I learned) that on #MacOS it is really easy (and fast) to create read-only filesystem snapshots with `tmutil` in a shell script so that I can make backups with #Kopia using those filesystem snapshots. Note: needs APFS as filesystem. Neat!
I updated my gist accordingly: https://codeberg.org/jwildeboer/gists/src/branch/main/2025/20251227-Kopia-Garage-Backup-Mac.md

One of our suppliers sent us some merch. And @leece had a great idea...
