Hello Luca, ok. Ping works - this is an initial step. Look here on my small box:
fred@scanner:~ $ systemctl status saned.socket ● saned.socket - saned incoming socket Loaded: loaded (/lib/systemd/system/saned.socket; enabled; vendor preset: enabled) Active: active (listening) since Sun 2020-04-12 11:07:57 CEST; 9h ago Listen: [::]:6566 (Stream) Accepted: 0; Connected: 0 does this show the same on your site? On the "main" pc I have only the net backend enabled: cat /etc/sane.d/dll.conf | sed '/^#/d' net can you check this? sane-find-scanner finds nothing. fred@djunix:/etc/sane.d> scanimage -L device `net:scanner:hp:libusb:001:002' is a Hewlett-Packard ScanJet 63x0C flatbed scanner default device is `net:scanner.karlsruhe.edu:hp:libusb:001:002' Hope this helps, best Dieter Am Sonntag, 12.
