⚪️ Linux Data Encryption: Choosing Between LUKS, eCryptFS, and ZFS Encryption 🗨️ Many Linux distributions offer built-in security options such as full-disk encryption (LUKS), folder and file encryption (eCryptFS), or even encryption provided by ZFS—a filesystem not native to Linux. Which of these available approaches makes the most sense today? Let’s take a closer look. 🔗 https://hackmag.com/unix/luks-ecryptfs-zfs?utm_source=mastodon&utm_medium=social&utm_campaign=repost_hackmag_to_socials #unix

⚪️ Four Bytes of Power: How I Found the CVE-2021-26708 Vulnerability in the Linux Kernel 🗨️ In January 2021, I discovered and fixed five vulnerabilities in the Linux kernel’s virtual socket (vsock) implementation, collectively tracked as CVE-2021-26708. In this article, I will show how they can be used to compromise the entire operating system while bypassing the platform’s security mec… 🔗 https://hackmag.com/unix/linux-core-cve?utm_source=mastodon&utm_medium=social&utm_campaign=repost_hackmag_to_socials #unix

This is the umpteenth time I've tried this, starting with version 1.6.1 😅 Could this be the definitive? I hope 💪 Now I have to config automount for external disk/USB keys and I need to find a way to encrypt my external disk and use it both in GNU\Linux and NetBSD. CGD (I never tried it on Linux and I didn't find anything online)? ZFS? Anyone have an idea? I know I can use OpenSSL or GPG but I think it's better and more confortable to encrypt the full drive... P.S. I love NetBSD but pkgin is really slow 😅 (It's probably not a problem with pkgin, but rather my Wi-Fi card.) #bsd #netbsd #bsdunix #unix #unixITA #unixitalia #guuf #guufxmpp #guufITA  #linux #linuxITA #linuxitalia

Mission accomplished, it seems! I must have messed something up during "sysupgrade etcupdate" because my user was no longer in the "wheel" group, but luckily it wasn't a big deal (thanks usermod 🤣) Then I updated pkgsrc with "cvs update -dP"  and edited /usr/pkg/etc/pkgin/repositories.conf to change the release number. I hope that’s correct! The update of all packages was successful, so I’m assuming it is. Is it normal that "pkgin upgrade" re-download and reinstall all packages, even those that are already the same version? I'd say the overall experience has been very positive. P.S. i3status gives me an error if I use UTF-8 "icons" (it worked with 10.1), but it's not really a big deal. #bsd #netbsd #bsdunix #unix #unixITA #unixitalia #guuf #guufxmpp #guufITA #linux #linuxITA #linuxitalia

Unfortunately, for of my university mail account, I have to use Microsoft Outlook (I know, I know! Luckily, I’ve set up a redirect, so I hardly ever have to use it). Tonight I tried using Firefox on NetBSD, but “Something went wrong.” When I changed the user agent and set it to "Firefox on Linux", everything works fine, no problems, nothing "was wrong"! In short, I think “Microsoft loves open source" but not NetBSD 😆. One more reason to keep using it 😈 (Forgive the corny joke, I know MS doesn’t actually love open source at all 😆) #bsd #netbsd #bsdunix #unix #unixITA #unixitalia #guuf #guufxmpp #guufITA #linux #linuxITA #linuxitalia

Good things take time: NetBSD 11 is here NetBSD 11 arrived later than announced, but now runs on RISC-V and offers ultra-fast MICROVM kernels for i386/amd64. https://www.heise.de/en/news/Good-things-take-time-NetBSD-11-is-here-11395266.html?wt_mc=sm.red.ho.mastodon.mastodon.md_beitraege.md_beitraege&utm_source=mastodon #Betriebssystem #BSD #IT #OpenSource #Unix #news

How do people manage to shoot themselves with rm? I’ve done so with disk partitioning, I’ve done that with #Git, but I can’t think of any such cases with rm 🤔 (Maybe it’s because I’m doing most of my file management with #Emacs + Dired…) #Linux #Unix

Still no good news with the freshly out #NetBSD 11.0 RELEASE. S3 suspend woke up with dead WiFi (Intel 8265, iwm driver), in addition to keyboard and touchpad as before on my #ThinkPad T470s. So basically dead machine and no way to reset unless long press power button for a hard reboot. Desktop usability needs more love. #runBSD #BSD #Unix #AskFedi

I accidentally came across this #MediaTek #MT7601U #WiFi driver for #NetBSD on GitHub: https://github.com/MakwanaVihas/gsoc_2k22 but it seems long abandoned. I wonder if someone knows how to use it. I actually have such a USB WiFi dodge, and since the #iwm driver works on and off for my Intel 8260 card on NetBSD I think I can give this a try maybe. #RunBSD #BSD #Unix

After a few months of work, slackfetch has reached a mature 1.0 release. A minimal and readable system information utility for Slackware, inspired by ufetch. The normal output and a cowsay -n composition are shown below. https://forge.slackware.nl/r1w1s1/slackfetch #Slackware #Linux #Unix

I very much am interested in looking OS designs beyond #Unix.

For instance I felt a real need for a different programming interface, OS and filesystem while I was doing research. I thought I wanted a #Lisp Machine comeback(hence title of the blog post below). But after research, I found the precise term to be "residential style developement". Below is me blog post:

https://far.chickenkiller.com/computing/do-i-need-a-lisp-machine-comeback/

I have also seen other software developers complaining about storage interface in Operating Systems and programming languages. For instance, here's a quote from Viktor who develops #Marginalia search engine complaining about this:

This is mostly a post to complain about something > that chafes. I wish there was a programming language (ideally several) that acknowledged that computers have hard drives, not just a processor, RAM and other_devices[].

His blog post is here:

The key to knowing if a FreeBSD box reboot is needed lies in comparing the installed kernel version with the currently running kernel version. How do you do that?

1 Get the version of the running kernel: freebsd-version -r

2 Get installed FreeBSD kernel version: freebsd-version -k

3 Since 14.4-RELEASE-p7 & 14.4-RELEASE-p8 are different versions, reboot it sudo reboot

More here if you want to do this in automated way with ansible https://www.cyberciti.biz/faq/freebsd-determine-if-a-system-reboot-is-necessary/

Breaking! 🚨 🎉 Ayer quedó finalmente instalado en el rack de servidores de Undernet el equipo dedicado a la comunidad Tilde-UnderNET. Se trata de un proyecto Pubnix (servidor Unix de acceso público) corriendo sobre OpenBSD 7.9 con servicios legacy como IRC, finger, FTP, Usenet, Gopher y Gemini. La idea es fomentar el intercambio de ideas, código y experiencias en un entorno donde se privilegia el uso de la terminal de texto plano. No tenemos claro si es la primera iniciativa de este estilo en Uruguay (o por lo menos activa) y nos motiva mucho inaugurar nuestro propio rincón nerd. Todavía quedan un par de cosas por pulir, pero ya tenemos varios servicios online y funcionando. Les dejo algunas capturas. Si quieren solicitar una cuenta pueden hacerlo enviando un correo a contacto@undernet.uy con las razones para unirse, un username de login y una llave pública SSH. Todavía estamos discutiendo, proponiendo cosas y tirando ideas. Nuestro canal de discusión principales son el grupo de XMPP xmpp:tilde@salas.undernet.uy?join y la propia Usenet interna #tilde #plaintext #textoplano #retro #consola #terminal #unix #pubnix #uruguay #undernet #openbsd #nerd
