I created a VM in the same network of the Raspi, with Debian Buster, too. I installed a fresh sane on this VM and tried to detect the scanner. Nothing... I see in the syslog of the Raspi, that the VM is authorized (access granted), I see with tcpdump on both devices data, but scanimage does NOT detect any network scanner... No Firewall between the devices, no network restriction, same version of all programs. Curiously, I can see Broadbast packets sent from both the Raspi and the VM, but the answer to these queries comes just from the network printers in the network. > Moreover: if your scanner should be promoted on a net that is not routed > through the ethernet or wlan card you'll have difficulties to get things up > and running. The network 192.168.5.0/24 is my network for printers. It has access to my NTP-Server and my Mail-Server and my PC-Network (192.168.10.0/24) has full access to the printer network. With all printers and the old scanner (HP OfficeJet 6500a) it works... Any idea? Thanks Luca Bertoncello ([email protected])
