RaidMachines -- vendor went out of business -- 24-disk enclosure has been causing issues with each replacement disk in the same slot. I am starting to think it is indeed more of enclosure issue (than the disk) that make #ZFS to note read-write errors.

I am looking for new 2U-4U _reliable_ #JBOD enclosure with 3+-year warranty to shove ~16-24 SATA 14+ TB disks in.

It needs to have SATA HBAs properly supported by #FreeBSD. I know of LSI 9300 series; getting rather hard to find on its own.

I had looked at some hardware of 45Drives, perhaps this time last year, but I had failed to find a JBOD specifically. I would much prefer to be in control of the OS & file system (ZFS).

Or, should I just order from SuperMicro?

I solved one issue, and now two more popped up. My Proxmox backups were super slow because of my router. I got a Netgear GS108E Gigabit switch, and now backups are way faster.

(Please boost .. Need urgent help)

Para los que estén empezando con nftables, o vienen de iptables, una breve lista de los principales matches/selectores para identificar tráfico.

Well - I just absolutely lost my temper with a client and their website provider because the website provider deciding sending contact form emails from an unregistered domain name is perfectly fine - ignoring my advice of why you should not use basic SMTP authentication for contact forms and I recommended they either set up their own mail server to handle it or, preferably, use something like formspree or basin.

But no, unregistered domain name it is, and apparently everything is fine.

I am strongly not in support of this. It's stupid. And I have told them so.

Networking Windows Commands — Essential Cheat Sheet for Cybersecurity & IT Pros

Networking commands in Windows are must-know for troubleshooting, incident response, and security monitoring.

Security Tip:
Always monitor netstat and tasklist during incident response to spot suspicious connections or hidden backdoors. Pair with SIEM logging for stronger visibility.

Disclaimer:
For educational & authorized use only. Run commands only on systems you own or have explicit permission to analyze.

Diese Woche auf Arbeit: Woran machst du eigentlich fest, dass deine beste Freundin deine BF ist? Naja im Grunde ist es ganz einfach:

- Ich habe nicht das Bedürfnis auszurasten, wenn sie meine EDV berührt
- Ich lasse bei ihr zuhause Laptop und Handy entsperrt rumliegen
- Wenn sie die entsperrten Geräte nutzt, möchte ich sie ihr nicht entreißen
- Wenn sie bei Nutzung "Ups" sagt, bleibt der Blutdruck unter 100

Mehr Beweis geht nicht!

81.30.107.134, qui essaie des noms d'utilisateur sur le port de soumission SMTP, vient de tenter sa chance avec "Reception123". Il y a vraiment des comptes avec ce nom là ?

We have managed to finally move from Gitea to Forgejo - git.trom.tf/ - thank you @esh for doing it :).

But we had to move repo by repo so we could not move the users. Only 3 other users used our git, and all of them were not active for the past year. This TROM Git is pretty much exclusively used for our TROMjaro project, but anyone can request an account there and use it fully.

Now TROM.tf is fully moved to the new server!

Okay #Ansible admins - who can point me to some in depth examples of dynamic inventory generation (specifically with vmware.vmware if possible)?

I need some inspiration and references for best practices regarding nested groups generated from vcenter tags and I’m struggling to build a mental model, and how to best enumerate through things like rolling-safe & blue-green patching groups etc.

All of the references I’m seeing so far are incredibly surface level thus far - and I need a sanity check. (Thanks!)

Something about managing SSH keys trips me up every time I set them up on a new device. I understand them incrementally more each time but I have to re-learn some concepts every stinkin' time. I'm now leaning into using the capability of @bitwarden to store and manage them hopefully in a more cohesive way than what I've been doing. Long term this seems like a pretty good avenue but people have a million different strategies for managing keys & which way is best seems murky

For the weekend crowd: "Networking for System Administrators, 2nd ed" is now live on #Kickstarter! Back it and get a free ZFS book.

Sometimes you work on the same problem all day only to have the outcome of your efforts be nothing more than a hopefully well-written bug report. #sysadmin

Is anyone else getting a huge number of bot visits from servers in the Fastly network? I'm seeing junk traffic that approaches low level dDOS numbers and a huge chunk of it is coming from Fastly data centers.
