In steps closer to starting my Linux channel. Preparations are fully underway, like creating thumbnails. Learning along the way, so it takes a few weeks. Still, making good progress

Exposing your home lab to the internet can open a path into your personal accounts and even your work assets.

In our latest blog post, Morgan Davis shows how to cut that risk with low-cost controls you can apply today, no enterprise tools needed. It teaches security thinking to help you reduce your attack surface and more.

TZAG #fediverso!!

Les comparto un nuevo artículo en el blog de #juncotic!

"nftables matches: algunos selectores útiles"

https://juncotic.com/nftables-matches-algunos-selectores-utiles/

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

#TZAG #fediverso!

Ayer estuve toda la tarde preparando y grabando un solo ejercicio práctico de configuración de firewall dual con nftables... acá algunas actualizaciones recién salidas del horno

La semana que viene empiezo a editar y ultimar los detalles!!

Interested in how Debian LTS works and what’s ahead?

The recorded BoF session from #DebConf25 is now online!

The session had engaging discussions on having point-update “releases” for LTS with Debusine, packaging security updates for firmware-nonfree, ca-certificates, and work towards compliance with new regulations like the #CRA.

Watch the recording here: https://meetings-archive.debian.net/pub/debian-meetings/2025/DebConf25/debconf25-670-debian-lts-bof.av1.webm

Debian 13 “trixie” is now the new Debian stable!

It will be supported for the next 5 years by the Debian Security team (https://security-team.debian.org/) and Debian LTS (https://wiki.debian.org/LTS) team, with up to 10 years of support via Freexian’s Extended LTS (https://www.freexian.com/lts/extended/).

A big congratulations and thank you to everyone who made this release possible!

It’s not magic (mostly). Get a peek into the life of a #SUSE security engineer: code audits, vulnerability hunts, and making o#pensource a bit less “oops.” Watch this #oSC25 session for the war stories. #InfoSec #openSUSE #LinuxSecurity https://youtu.be/J-MkQmDTAWc?si=uRGxjMWQSBZSQNNj

A warm thank you to #tropicsquare for backing #openSUSE Conference 2025! Together we push for transparency, trust, and open security. #oSC25 #LinuxSecurity #openhardware https://events.opensuse.org/

@triskelion @purism I appreciate what GrapheneOS and other projects are doing. I wish gOS good luck in:
- getting early access to future #AOSP sources as development is no longer public.
- fixing the myriad of #Google shenanigans with the OS and Chromium.
- getting mental health help for the main developer - he deserves all the help he can get.

Unlike gOS, #Linuxphone development is not riding on decades of Google funded development of the OS. Progress is therefore slower but it is improving gradually.

Besides #PureOS, there is also #Mobian and #postmarketOS - I especially look forward to the latter's future #ImmutableOS version which would have security benefits as well.

Ubuntu 20.04 “Focal Fossa” has reached end-of-life!

With the release of Ubuntu 24.04 LTS, regular support for 20.04 has ended.

This also affects Cryptomator: Future releases will only support Ubuntu 22.04 and newer.

Still running Ubuntu 20.04? Now’s the perfect time to upgrade!

Does anyone have any handy guides for properly locking down a linux server used for hosting? I've been doing an okay job with mine but I think if anyone has a good guide about how to make sure I didn't miss anything, that would be nice!

It's primarily for web hosting, including fedi, and sometimes as a fallback matrix/chat thing. Boosts appreciated!
