CW: Sysadmin life existential edition
We've just had someone in another team create a host called "something".
We are yet to identify the responsible user, so for now it is someone's something.
And something is reporting an error in our monitoring dashboard. So something is wrong with something for someone.

Today's sidequest: Find a way to run a shell script before printing a file via CUPS on macO. The script basically does a single `curl` to power on the printer’s outlet.
Have you done something similar? Perhaps with a filter? I don’t need to manipulate print at a at all, just run a single curl before the job is sent to the printer.
Links to solving this are welcome! (Yes, I’ve obviously searched around and read documentation already, but nothing seems to work so far.)

Too real to be funny. Or funny, because it hits too close to home?

The Ops part of DevOps in 2026 seems to include trying to work out what Claude has deployed on AWS so Cloudflare DNS can be configured to point at it. If anyone wants me, I'll be out back shouting at the bins. #sysadminlife

Random tip. On a rpm based Linux system like Red Hat Enterprise Linux, Rocky, Fedora etc, you can find the rpm package that installed a certain file/binary with `rpm -qf /path/to/file`. This is an ancient way of doing that, but really fast, as it uses local info from the rpmdb :). I just used it to find out that the `/usr/sbin/ether-wake` command that I use to switch my homelab machines on via wake-on-LAN (WoL) magic packets lives in the `net-tools` rpm :)

To celebrate #SysAdminDay, I updated and rebooted my 9 servers, as I do every Friday :) (These are my private machines, so if something goes wrong, I have the weekend to fix stuff). The twist today: this was done while I am on vacation at my parents, so all remote, including powering my homelab machines on and off :)

It's funny when someone downloads a 3 GB ISO file, and calls it "live CD". 😄

Major #SysadminLife work completed: I now have three security tokens for encryption and authentication, all configured identically :flan_hurrah:
I used to use a Yubikey for this, but was always terrified of getting the PIN wrong three times and it bricking itself. These days, I can't afford the ≈€80 to replace it.
I've picked up STM32F103CBT6 development boards and flashed Gnuk on them. Because it's FLOSS I disabled the annoying flashing LED too. Total spend: €5 for three!!

This is one of the best ideas I have ever had.

The moment you begin using any of the many vibe-coded software projects that are popping up everywhere, you inherit its technical debt and future maintenance.

Spent a day troubleshooting Client IPSec IKEv2 connections that kept failing. In the end it was… NOT DNS, but PKI.
Also, I suspect a weird edge-case bug in #OPNsense’s certificate handling…Either way… it’s working again now… so I can finally begin looking into the things that I *actually* wanted to build. A way-too-familiar situation.

Storage maintenance en dat merk ik direct aan de Mastodon process queues die achterop geraken en images die trager laden 😦
No worries folks, nog maar pakweg 5TB data moven en dan zou het weer vlot moeten gaan !

Guten Morgen werte Herde :masto_smile:
Und täglich grüßt das Murmeltier. Die guten #proxmox Server brauchen wieder Updates. Also gibt es gleich wieder was zu tun am frühen Morgen.
Der 🍰 Tag gestern war sehr schön. Es kam auch wieder 🪢 zum Einsatz. 😏
Habt es fein heute.

Gestern einen HP Switch ausgebaut, der rumgespackt hat. Jetzt bekommt das Teil erstmal eine neue Firmware verpasst.
Vielleicht löst das schon die Probleme.

I have turned off a computer that appears to be disconnected from everything, is performing no detectable tasks, is referenced in no documentation, the purpose of which is unknown to anyone, and I welcome the many challenges of this role.

Possibly controversial take: I like when the InfoSec team is very active/present and breathes down my neck. Gives me the confidence that I'm either doing something right, or they can stop me from doing something wrong. Of course it doesn't remove my responsibility of doing the appropriate research.

I've had this stuck in my head for a while, so now it's your turn.

You're welcome.

Friday is update time for my homelab and public servers. Because, should something fail, I have the weekend to fix it. But, as always, nothing failed. All 9 RHEL (Red Hat Enterprise Linux) servers got their `dnf update`, followed by a `reboot`. This time the security updates included important nginx fixes, moderate coreutils stuff. Also a emu-kvm bugfix. All is good, machines and services are up and running again. 20 minutes of well invested time. Coffee next :)

As it turned out the Asus BIOS upgrade caused the problem. It simply refused to boot if it can see >= 8 drives. Hiding one drive on the RAID-controller and it booted.
Then unhide using storcli, import the foreign configs (because of RAID-controller firmware update) and everything was fine.
Question and answer is on ServerFault, so future LLMs could solve the problem for you -.-Lessons Learned: Next time we will move data away from one of our eight storage servers and test updates on it beforehand.

Today has already been A Lot and I didn't sleep super well last night so I'm going to do a sensible thing and let my brain rest and enjoy some caffeine before I attempt to engage with VLANs.
Maybe even leave it to tomorrow and do some other admin instead.

🚀 Oh joy, another Jira alternative claiming to revolutionize your project management world by letting AI pretend to be your coworker 🤖. Because who doesn’t want to spend their day programming a config file just to avoid using a tool that already works? 🙄 Self-hosted, because what's more fun than playing sysadmin for your new AI overlord? 😂

Die freundliche Empfangsdame kommt zu mir ins Büro und fragt, ob sie mir bis morgen was reinschieben kann.
Wir prusteten dann fast zeitgleich los. 😂

2026 und immer noch kein MDM im Unternehmen. Also richtest du jedes neues Smartphone für einen User händisch ein und plagst dich jedes Mal durch die Accounterstellung, die auch immer komplizierter wird.
Oder ich vielleicht langsam zu alt kann natürlich auch sein. 😂
