My daughter bought an 18-year-old Dell Optiplex 960 with no operating system on eBay and asked me to install Linux Mint for her. I reluctantly agreed to keep the peace. But I was surprised anyone would sell such a machine with a hard drive. Well, it arrived today and the hard drive was so thoroughly wiped as to be invisible (i.e., it contains no hard drive). It also was poorly packed and arrived with the face plate broken loose, a dead cricket and a few pieces of broken plastic inside the case, and one of the memory cards dislodged. Even after reseating the memory card, there was still a hardware problem with the memory. At least it didn’t burst into flames when I plugged it in and tried booting it up. But I did remind myself where the fire extinguisher is located. Why am I doing this? Because my daughter has schizophrenia and is paranoid about AI, she wants hardware no newer than 2008, and I am trying to keep the peace. Why 2008? Your guess is as good as mine.

Guix goes on the Thinkpad.
The graphical (TUI) install process is clear and concise. If you don't like the suggested disk partitioning scheme its straightforward to customize. I didn't feel the need to switch to a console to do a manual install.
Disk layout is a small ESP partition, with the rest going to a LUKS encrypted root partition. Kernel 'linux-libre' supports the Intel ethernet without binary blobs, and I've ordered a AR9271 USB wifi adapter to keep things libre.
Onward!

So, I'm at a good point with my #homelab , it basically just works and covers most of the things I need. Immich up and running (rest of family later in the year), Tailscale so everything works wherever (stress tested with a month long European holiday). 321 with a combo of Proton, restic etc. Management and monitoring possibly over-engineered for what I actually have, but basically I have notifications and real time info left and right. Got note taking covered, got jellyfin, got an rss reader, got domain names for nice back end. Have a recipe app largely untouched. Stirling pdf.
I have a smaller UPS set up.
Future state involves a proper big boy UPS, a proper NAS/hdds and a second dedicated machine for Immich ML and some local AI.
All of which is to say: what other fun things can I add to my system? Services, apps, etc that I can self host? I've trawled the self hosted site.
I really just dig the tinkering at the moment. #linux #idlehands #fomo
Is there a GUI tool (no Terminal) that allows you to rename BOTH files AND folders and is RECURSIVE?
The best I have tried is Stencil, but it doesn't do folders.
Sorry to be passive aggressive but please only recommend something you have used, do not ask "AI" or recommend the first hit on a search engine.
No, I don't care how easy it is to do in the terminal with one line. That is not the question!

Ogni tanto una vulnerabilità ricorda quanto la nostra infrastruttura digitale dipenda da librerie fondamentali che diamo per scontate. È il caso di HollowByte, una falla di tipo Denial of Service scoperta dal team di ricerca di Okta in OpenSSL: con un payload malevolo di appena 11 byte, un attaccante remoto e non autenticato può costringere un server ad allocare quantità di memoria completamente sproporzionate, prima ancora che l’handshake di sicurezza abbia inizio.
Per chi gestisce server web, database o qualsiasi servizio che parla TLS — quindi, in pratica, quasi tutti i sistemisti — vale la pena capire come funziona e, soprattutto, cosa fare subito.
L’handshake TLS comincia con un messaggio ClientHello incapsulato in un record. Ogni messaggio di handshake porta un header di 4 byte che dichiara quanto sarà grande il corpo del messaggio in arrivo.
Nelle versioni vulnerabili di OpenSSL, il buffer di ricezione viene allocato sulla base di quella lunghezza dichiarata dall’attaccante, prima ancora che i dati siano effettivamente arrivati. La catena di chiamate è semplice quanto pericolosa:
Lettura header (4 byte)
→ grow_init_buf()
→ OPENSSL_clear_realloc()
→ malloc(dimensione_dichiarata_dall_attaccante)Poiché a questo stadio non esiste alcuna validazione del payload, un header che dichiara una lunghezza di 3 byte può far allocare fino a 131 KB basandosi solo sulla dichiarazione del pacchetto, che nessuno verifica. Il worker thread resta poi bloccato ad attendere dati che non arriveranno mai.
Tenere connessioni aperte per esaurire i thread è un trucco vecchio quanto Slowloris. Quello che rende HollowByte più insidioso è l’interazione con la gestione della memoria di glibc (GNU C Library).
Quando una connessione dell’attaccante si chiude, OpenSSL libera il buffer — ma glibc non restituisce immediatamente al sistema operativo le allocazioni di dimensione piccola o media: le trattiene per un possibile riutilizzo. Lanciando ondate di connessioni con dimensioni dichiarate casuali, un attaccante impedisce all’allocatore di riutilizzare in modo efficiente quei blocchi liberati. L’heap si frammenta pesantemente e la Resident Set Size (RSS) del processo cresce in modo continuo.
Il punto critico è questo: anche dopo che l’attaccante si è disconnesso, il processo resta con un footprint di memoria permanentemente gonfiato. L’unico modo per recuperarla davvero è riavviare il servizio.
Il team di Okta ha testato istanze OpenSSL patchate e non patchate dietro NGINX, sotto diverse condizioni di carico:
Dato che OpenSSL è incorporato ovunque, l’impatto potenziale copre web server (Apache, NGINX), runtime di linguaggi (Node.js, Python, Ruby, PHP) e database (MySQL, PostgreSQL) che si appoggiano alla libreria per TLS.
Il team OpenSSL ha risolto il problema passando a una crescita incrementale del buffer (merge delle pull request #30792, #30793 e #30794): invece di fidarsi della lunghezza dichiarata nell’header, il buffer cresce solo quando i byte arrivano effettivamente sulla connessione. Una dichiarazione senza seguito ora non costa più nulla al server.
Il fix è stato incluso silenziosamente nella release OpenSSL 4.0.1, con backport altrettanto silenziosi sulle versioni:
3.6.3
3.5.7
3.4.6
3.0.21Un dettaglio non trascurabile: OpenSSL ha trattato la correzione come un semplice hardening fix, senza assegnare un CVE ufficiale, nonostante la gravità dell’impatto. Questo significa che molti scanner di vulnerabilità basati solo su database CVE potrebbero non segnalare l’esposizione: va verificata manualmente la versione installata.
Alcune azioni concrete da mettere in pratica sui vostri sistemi:
openssl version -a# Debian/Ubuntu
apt update && apt list --upgradable | grep -i openssl
apt install --only-upgrade openssl libssl3
# RHEL/Fedora/Alma
dnf check-update openssl
dnf update opensslssl_handshake_timeout 10s;
client_header_timeout 10s;HollowByte è un buon esempio di come un bug apparentemente piccolo — la fiducia cieca in un header di pochi byte — possa diventare un vettore di Denial of Service difficile da rilevare con le metriche di monitoraggio standard, perché resta sotto le soglie di allarme sulla banda e sulle connessioni. La buona notizia è che la correzione è già disponibile e il percorso di mitigazione è chiaro: aggiornare OpenSSL su tutta la superficie esposta, non fidarsi solo dei database CVE per capire se si è vulnerabili, e aggiungere il monitoraggio della memoria residente ai controlli già in essere sui vostri servizi TLS.

Am I the only one confused by the names for openSUSEs editions?
Leap: As in "...but a giant leap for mankind" that reminds me of conquering a new frontier is of course the stable LTS edition with older software.
Tumbleweed: As in "nothings going on here, it's deserted, empty, inactive, here's an 80s western scene of a ghost town and rolling tumbleweed" is of course the rolling release edition with the most recent software versions.
440 CVEs dropped to kernel cve-announce in the last 24 hrs?!?!?!?
