hey so. looking for a job (NZ or fully remote willing to hire a kiwi) in SRE, security, or linux/Unix system administration. 15 years experience administering Linux and Unix boxes, intermediate level of experience working with docker compose and containerisation and container security. No prior job experience unfortunately, all those 15 years were mostly personal projects and small-scale stuff for friends. I'm also 26, so I started when I was 11, explaining the no jobs so far. Currently running an entire multi-machine personal cloud infrastructure with a demonstration of all the services I have running at https://status.highenergymagic.net. Three machines, 72 docker containers. One running most of them, one running Mastodon+glitchsocial, one running the uptime monitor. encrypted root on ZFS, alpine linux, gVisor on supported containers, plan to move to Kata. Entirely willing to accept entry-level job placements, no expectation of being paid a lot or anything, just want to be doing something and move the needle a little on my current "being broke" status. Currently using gVisor, docker compose, and kata containers in production, experience with Linux, docker, Net/Open/FreeBSD, Cisco IOS, Juniper Junos, Mikrotik and UniFi, configuring and administering Asterisk, plus extensive experience with IBM AIX and Sun Solaris. #fedihired #infosec #cybersecurity #linux #unix #docker #sre #DevOps #GetFediHired

what do you #Linux folks use as a stupid simple DHCP server daemon? #Kea seems a bit overkill for what I need, and isc-dhcpd is effectively unmaintained.

$ sudo resolvctl status is taking forever.

I really, really, really wish #Linux would implement SIGINFO.

Today I came across a weird #printer problem. From #Debian #Linux I could print to the #Canon PIXMA printer in simplex or #duplex.

BUT, in duplex mode it would print a side, eject the paper, re-load the paper, then eject it again without printing anything on it, and then start the second page on a separate sheet of paper.

This happened from my PC and a separate one using the stock #IPP driver in #CUPS

Annoyingly it works perfectly in Windows...

Your nightly reminder that the bugs are Long Term Stable too and the maintainers of those projects can't fix your distro.

Recently I got asked about my @BoxyBSD@bsd.cafe project, which offers free VPS instances of vary #BSD based systems for learning and educational purposes and I'm happy to share that this projects remains available. Several things could finally be clarified to continue this service to make sure people can learn and practice on real #FreeBSD, #OpenBSD, #NetBSD systems to #RUNBSD. Also, BoxyBSD starts moving over to #Sylve on #bhyve.

But not only that! We could also get some more new resources and locations to scale and this also brings up another new project for #free Linux #VPS instances at https://boxedtux.com (Fedi: @BoxedTux@mastodon.social) where people will be able to learn and practice on different #Linux based distributions (e.g., #Debian, #Ubuntu, #Rocky,...). BoxedTux utilizes #Proxmox clusters as a foundation.

Hope you like this small update... Over & out!

I spent the last couple of days examining the source code and understanding the Copy.Fail vulnerability in detail. This vulnerability happens on the shoulders of 4 key components:

- Page cache
- AF_ALG
- algif_aead
- splice()

In this video, I talk about these components and demonstrate how the CVE-2026-31431 vulnerability allows attackers to gain root access by modifying the “su” entry in the page cache.

It works, but like lilo back in the '90s. Actually, that's probably not fair to lilo.

How to Install OpenBSD (2027 Edition)

Just about every consumer facing operating system, search engine and service is using AI now to some extent. I’ve seen folks switching to #openbsd from Linux/Mac/Windows…but what about other services? Proton has AI, and damn near every internet search engine has AI, even the ones that claim to be private and secure. I’d be interested in hearing some realistic tech stacks and workflows that don’t involve tools with AI in them or created with the help of AI. If you are willing to share please comment.

👩‍💻​ My So Called Sudo Life - day 500: still a newbie edition 🆕​

Dear Fedi friends,

Today marks the 500th day of my self-hosting adventures and I'm celebrating it with... a slice of humble pie:

🔗​: https://blog.elenarossini.com/my-so-called-sudo-life/my-so-called-sudo-life-day-500-still-a-newbie-edition/

Also: please remember to update your Linux system to patch the critical vulnerability that has been found.

Oh, and @zeitkapsl have a #Linux desktop app and one for the command line!

(The desktop app only works as flatpak for me, the RPM has conflicts on my Fedora install).

(EDIT: Problem solved! With this reply https://techhub.social/@konform/116490565176455678)

Librewolf keeps opening the tabs that were opened last, even though I have this tickbox unchecked. I want a fresh session all the time. I never want it to restore anything ever - even if it crashed.

I was able to get this behaviour in my last setup, but I forgot what I did (recently I wiped my hard drive and did a fresh linux install).

Does anyone know how to get this behaviour?

#TIL You can copy or rename files without retyping the path:

❯ cp /your/long/path/config.toml{,.bak}

This expands to:

cp /your/long/path/config.toml /your/long/path/config.bak

Works also with `echo` (nice for testing).

Thanks to @irom for recently pointing me in this direction. 👍️

So you read about #CopyFail, and are like… owww, shit. But then you see that it was responsibly disclosed after being fixed in main, we had releases since, they went stable in #Gentoo (over other #security fixes), so we should be good, right?

Except that it turns out that after it has been fixed in mainline, nobody bothered actually backporting the fix to all the LTS branches. And it doesn't apply cleanly (https://social.treehouse.systems/@thesamesam/116490971618284574). What a shitshow!

(And we've been only talking how 5.x don't get vulnerability fixes in time — but it turns out that anything but the latest is insecure to use!)

#Gentoo #Linux

#KDE #Linux #KDEConnect #computers #software

The exploit includes cpu-specific shell code (ELF). I have the toolchain working to build working shell code and the exploit binary on both Linux/86 and Linux/ARM, but the exploit doesn't work out of the box on ARM.

Anyone got further details if this vulnerability is only valid for x86?

#arm #copyfail #linux #exploit #x86

Holy. Fucking. Fuckballs.

This exploit is... insane.

Right, question for Linux users - I'm getting some surprise money and I'm thinking I'll invest in a colour printer so that I can make my own art prints at home.

I had an Epson Eco-Tank in South Africa but was having a hell of a time calibrating the colours.

Suggestions for printers that work well on Linux (I know Brother are good), that are good for colour art prints?
