Happy #Sysadmin Appreciation Day to all who celebrate! https://sysadminday.com/
It's easy to forget us sysadmins, since if we do our jobs right, we squash potential problems and outages before they become noticeable issues! That in itself is worth celebrating!

2.5 Admins 257: Outage365

Two recent outages were handled very differently but show the dangers of centralisation, Let’s Encrypt is introducing certificates for IP addresses, and the differences between backup and production systems.

Registered for @EuroBSDCon! I'll be teaching TLS and email before the main con in one hideous day-long #sysadmin forced death march. You want in on this, I'm sure.

@alpine and I have been poking at #copilot vision. It looks like, as of right now, there’s NO OPTION to disable vision, or even copilot itself, domain wide. You need to disable or uninstall it *on every individual device*

Oh, and it reenabled itself without warning if you had it disabled org-wide previously

Any of you managed to run Mastodon using Portainer?

How did you run db:setup command? I'm unable to run it because mastodon-web container is stuck in "Starting" ..

"I’m not saying that a knowledge of promiscuous mode, fdisk, or window scaling leads to misery, but I will say that happy folks have no understanding of any of them."

The new #FreeBSD Journal is out, including my "We Get Letters" column.

The best IT folks document their weird fixes, answer beginner questions, and make time for the "silly" problems. None of us came in knowing it all. We all learned by asking someone else. Let’s be that someone when we can be.

#InfoSec #SysAdmin #DevOps #IT #tech

now don't get me wrong, there's benefits to ops people knowing how to script and code and be able to understand where the dev guys are coming from, and vice versa.. But doing it just to combine the two functions is like buying one of those all in one printer/fax/copier/scanner/coffe makers and wondering why all of them on their own fucking suck. #linux #sysadmin

"We have simple streamlined pipeline, we have 2 source control systems, 3 deployment frameworks, 3+ CI engines, 2 artifact registries, 17 CLIs, only 3 UIs, 5 SDKs, understanding how to issue Jira ticket properly, learning how to close a Jira ticket in time.

Very easy, you learn all of this on day 1 of onboarding, is the best developer experience"

People who work on DevOps, SRE, sysadmin and other infra topics, what OS do you use at work (for your workstation, not for your servers/containers/etc)?

Linux tip: Set `HISTCONTROL=ignoredups:erasedups` in your init script to prevent duplicate commands cluttering your history. Clean history makes command recall much more efficient. #Linux #SystemAdministration #SysAdmin

I just realised that I had never made an intro post, so here it is:

As you'll see on my profile, I'm a bit of a professional chimera. I studied an engineering field back in the day, but switched gears to clinical psychology when the stars aligned for such a big change.

I'm interested in very many things, and one day, I would like to either work in child-and-youth psychiatry, psychotherapy, or psychological counselling for minorities. Currently, I'm nearing the end of my studies, and I earn my bread as a Linux system administrator.

I've been busy preparing my community course "Basic Linux System Administration" for a few weeks now. The next instructor-led cohort starts in September.

Here's the public chapter on text editing with vim. You can use it outside the course context, simply as a concise #vim tutorial.

Shell tip: `${var%suffix}` removes the shortest matching suffix. `${var%%suffix}` removes the longest. `${var#prefix}` and `${var##prefix}` work the same for prefixes. Mnemonic: # comes before % on the keyboard. #Linux #SystemAdministration #SysAdmin

The unsung heroes are often the ones who stopped the train wreck before anyone even knew the tracks were faulty. That is why it's a thankless job, keeping the sky from falling. Mostly because when it doesn't fall, everyone just assumes it was never going to.

"ZFS snapshots as poor man's ransomware recovery"

It holds up. Better than you'd think.

Ransomware hits a server? I roll back to a snapshot taken 10 minutes ago. Immutable, local, instant.

No restore wizard. No cloud latency. No vendor lock-in.

Just:

zfs rollback pool/dataset@safe

Gone. Like it never happened.

You want real ransomware defense?

Immutable local snapshots

Offsite ZFS send/mirror

Key-based SSH, no password logins

Restore script you actually test

ZFS isn’t "enterprise." It’s survival-grade.
