Ich habe für meine Serie »CachyOS härten« eine kurze Anleitung geschrieben, wie man auf #CachyOS das #Login sowie #sudo und #su und #KDE (eher improvisiert) mit einem #Fido2 Token absichert. Getestet mit #yubico #yubikey #nitrokey, #token2 r3 und #thetis via #pam und #pam_u2f

Damit kann man dann #mfa mit 3 Faktoren (Token: PIN und Besitz sowie das normale Passwort) umsetzen.

Obacht: man kann sich beim nachbauen schnell mal komplett aussperren, also die beschriebenen Vorsichtsmaßnahmen beachten.

Falls jemand weiß wie man KDE/SDDM besser mit pam_u2f absichert, immer her mit den Ideen.

@[email protected] If you want you can, installing OpenBSD is lot easy than Gentoo/Archlinux but after of course you need to read handbook/wiki/guides/youtubetutors, the most thing you shouldn't give up on process I tried many disdros and on many of them I stuck when I first saw OpenBSD I got confused there wasn't apt/pacman/xbps even #sudo wasn't there it was #doas and pkg_add not systemctl it was rcctl and many other. But what i did to learn these I just tried, no one stand by me and teach what to do I just asked around in #irc community, wiki pages, youtube guides, it became my new hobbie, day by day, now I'm running my own OpenBSD vps I got my own #got server it is minimalist alternative of #git version focused on security by default, I got my own email server, even this account runs inside of it, Whole message I want to deliver to you is keep trying, you don't need motivation to achieve you just need to want it, Do you ever notice ants? How they act when they cannot reach on top of smthing they trying another way until they reach on top they just keep trying. If you stuck somewhere reach to us, we're together anytime glad to help you.

4. to test bad blocks on hard disk on Linux, sudo pv -nb /dev/sda > null or replace /dev/sda with the device identifier of your hard disk.

The errors will print in dmesg (comfortable viewing with command dmesg -TL=always|less -R).

pv may need to be installed as a separate package usually called pv.

It doesn't have a menu entry Menu->System->Hard Disks->"Check bad sectors on your hard disk".

It doesn't even have a menu entry Menu->System->Hard Disks->"Display instructions how to check bad sectors on your hard disk from command line", which I assume would be much easier to implement than the actual menu function, and almost as useful for me.

User experience (UX).

Csináltam egy merészet.

Van egy Lenovo Yoga 11e tablet PC-m. De, Linux alatt egyszerűen sosem működött a tablet funkció.

Hat éve van nálam, de együtt tudtam ezzel élni, mert igazából nekem egy valóban kis laptop kellett utazásokhoz, ha ügyet kellett oldanom alapon.

Sosem használtam ki tabletként. Még Windows alatt sem. (Igaz, Windowst csak és kizárólag az ősöreg, de LifeTime Garmin Nuvi GPS-em frissítéséhez használok egyedül, mert nincs kedvem kerülő utat keresni rá.)

De, úgy voltam vele, hogy ha már van mindenféle CLI-s AI agent, akkor teszek egy próbát azzal is.

Oda adtam a Claude AI CLI agentjének sudo joggal együtt, hogy... oldja meg, ha tudja.

Dolgozik bőszen. És, igazából nem csak azért nem félek, hogy elront valamit, mert nincs semmi szenzitív azon a gépen és pikk-pakk újra telepítem és kész.
De, azért sem, mert egyszerűen egy netes keresést nem tud megcsinálni anélkül, hogy minden oldalra külön rá ne kérdezne, hogy engem-e.

...és ugyanez minden lépésnél itt is. Egyszerűen nem tudok normálisan gépelni, mert a másik monitoron az ssh-ban folyamatosna nyomkodnom kell az entert a jóváhagyások miatt.

Kíváncsi leszek, mi lesz a vége!
