@dfx@techhub.social It shocks me that there are groups of #sysadmin that still have to administer to #windows #311 machines, and manage them (mainly point of sale machines from my understanding), but still. Blows the mind.

Okay, this is weird. I am seeing `tailscaled` spiking up to 250% CPU usage every other minute, with up to 60 MBit/s outgoing traffic on the `tailscale0` interface... and on the `wg0` interface I see the same amount of traffic during that period. I now disabled wireguard and the issue is gone. But I have absolutely NO idea why this is happening, what causes it, and why it (seemingly) suddenly started - I did not have this issue earlier today. All I did in between was update the unstable channel, but all packages involved here (tailscale, wireguard) are from stable. So... 🤔 I am at loss... #tailscale #wireguard #linux #linuxnetworking #networking #sysadmin #nixos

Another report forwarded to me by a client saying "your website is insecure because it accepts outdated encryption protocols" - naturally passed along to them by third parties. Yes, it accepts them. But it's a static website that simply provides some information about the company. Nothing critical, nothing dynamic. No data is exchanged. There is no login. We had already tightened everything up a few months ago (for me it's literally a one-line change), but they later told me that some visitors could no longer access the site and asked me to revert it. Probably older devices, but there are plenty of those out there. I know organizations that still use Windows 7, and I still occasionally see some XP clients around. So now I explained to the client that we have two possible choices: accept the "risk" (which, frankly, I'm not entirely sure what it would be, since even if someone decrypted the traffic they would see nothing that isn’t already visible by simply visiting the page normally), or lock it down again, potentially cutting off some devices, just like what happened a few months ago. The choice is theirs. We’ll see! #SysAdmin #IT

New series: FreeBSD Foundationals Part 1 is about Jails - specifically VNET Jails. What epair interfaces actually are (virtual ethernet cables), how bridges tie them together, why the host is basically a router for your jails, and what devfs rulesets control. Covers the full lifecycle from jail.conf through pf firewalling with NAT/RDR for IPv4 and direct routing for IPv6. Plus the gotchas that'll cost you hours if nobody warns you. Not a beginner tutorial, hardcore details. The useful middle. https://blog.hofstede.it/freebsd-foundationals-jails-from-chroot-on-steroids-to-full-virtual-networks/ #Unix #FreeBSD #Networking #Jails #DevOps #SelfHosting #Sysadmin

Heads up for any folks using @hetzner@mastodon.hetzner.social: scammers seem to be trying to exploit the recent bump in pricing by sending "unpaid invoice notification" e-mails. Easy to fall for it before morning coffee. "Update Payment Method" link obviously leads to a scam site, so not particularly hard to spot either. Be careful out there. :blobcatcoffee: P.S. yes I am aware of the shitty ways Hetzner treated a bunch of fedi instances; this is not a recommendation. #Hetzner #InfoSec #SysAdmin

New post: Neovim Crash Course for Sysadmins Not a beginner's guide. This covers the things you still get wrong after years of Vim - efficient navigation, why your paste lands in the wrong place (and the one-key fix), YAML indentation workflows, quick macros, and what Neovim's LSP actually gives you for infrastructure work. Written for people who edit configs and playbooks all day. https://blog.hofstede.it/neovim-crash-course-for-sysadmins-the-20-that-solve-80-of-the-pain/ #neovim #vim #sysadmin #devops #linux #ansible #yaml

I just published a new guide on evolving a single BGP router into a multi-homed, two-PoP network using FreeBSD, FRR, and PF. - Native peering on Vultr + 3 GRE transits - Tying it together with iBGP - Why stateful firewalls break asymmetric transit (and how to fix it) All for ~€18/mo.

At the start of the pandemic, I had already working from home for about six years and was very comfortable with the video meetings. The majority of the company was new to it though, and when I attended some meeting outside of my usual group it was a revelation for many that you could have fun with it. Most didn't know about having custom backgrounds etc. #sysadmin #videoconference #IDGAF #decorum #hijinx

Stop running setenforce 0 and pretending SELinux doesn't exist. I wrote a practical guide to actually working with SELinux on Fedora and RHEL: Contexts, booleans, troubleshooting denials, container volume labels, and the commands you'll actually use. No policy theory rabbit holes. Just the stuff that gets you unstuck. https://blog.hofstede.it/selinux-a-practical-guide-for-fedora-and-rhel/ #SELinux #Fedora #RHEL #Linux #sysadmin #infosec #itsec

A #SysAdmin / #MastoAdmin Question for folks Has anyone used mikrotik hardware in anger / in production? I've had enough now of my Unifi gear causing problems, this is the second gateway I've purchased which exhibits these random lock-ups / crashes and I'm very much over it so am looking at alternatives and mikrotik continues to be one that looks sensible. Just curious if anyone has much experience using it hands on?

I really like Veeam''s Backup solution especially on Linux because of the image based backups even with ext4. What I don't like ist the limited scheduling options. For that purpose I used some bash scripting and some SystemD units to help me out. I wrote a blog post about my process and at the end you can find a link to my git for the files. https://cperrin.xyz/en/2026/01/28/triggering-veeam-backups-on-linux-with-systemd/ #linux #backup #homelab #systemd #veeam #sysadmin

Ich mag die Backup Lösung von Veeam sehr. Vor allem unter Linux kann man damit leicht Image-Basierte Backups machen selbst mit ext4. Leider ist das Scheduling gerade unter Linux nicht gut. Deshalb habe ich eine Lösung mit SystemD gebaut. Ich habe einen Blogeintrag geschrieben der beschreibt wie das ging. Am ende vom Betrag findet ihr auch direkt einen Link zum Code. https://cperrin.xyz/2026/01/28/veeam-backups-unter-linux-mit-systemd-triggern/ #linux #backup #veeam #sysadmin #homelab

They say AI isn’t profitable. That’s not true. Twice just this past week, I’ve been contacted and paid to fix problems caused by developers who relied on AI to configure servers. #AI #IT #SysAdmin

AI models don’t really 'get' the BSDs. As a result, they often provide incomplete, imprecise, or flat-out wrong answers by defaulting to Linux paradigms. When it comes to illumos-based systems, they just completely lose the plot. This is becoming a serious issue for the BSDs and illumos ecosystems. We are seeing entire websites flooded with AI-generated tutorials and guides that are totally incorrect. Most people don't realize this; they follow the instructions, fail, and then assume that the BSDs doesn't work well or are 'unstable' because they have supposedly changed since the guide was written. Luckily, some people eventually find my blog, reach out, and finally understand what's actually going on. Others, unfortunately, end up on major social sites or comments, claiming that these systems are broken. In 2026, one of our greatest challenges will be teaching people how to vet their sources and filter information. And I see this as a very, very uphill battle. #IT #SysAdmin #FreeBSD #NetBSD #OpenBSD #illumos #News #UnderstandingText #Disinformation
