J’ai donc bloqué cette IP : 216.73.216.160 . En fait j’ai bloqué 216.73.216.0/24 et 3.141.17.0/24. C’est visible via : https://webanalyse.cyber-neurones.org/

Petit test d’installation de Ollama en version LXC via un script :

bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/ollama.sh)"

On va voir le résultat … actuellement m’a carte NVIDIA (ou Bios) de supporte pas le Proxmox Passthrough.
