[sane-devel] Problem with Sane over network

My first question, here...
So, I have a scanner, Canon LiDE35, connected via USB to a RaspberryPI
with Debian Buster.
The scanner works well and I can scan using scanimage.
I installed scanbd in order to manage the buttons on the scanner and now
I can copy and mail documents.
Last point: using the scanner from other PC in the network.
It does NOT work... :(
First of all: the Raspi is in a different network as the PCs!
Anyway I added this line to the saned.conf on the Raspi:
So I should use the scanner from all PCs in the network 192.168.10.0/24...
In my PC with Debian Stretch (192.168.10.3), I added this line to
that is the IP of the Raspi.
In /etc/sane.d/dll.conf on my PC I have:
so that I should be able to scan over network...
Unfortunately scanimage -L finds nothing... :(
In the syslog of the Raspi I see:
Apr 12 10:11:53 scanner systemd: Started Scanner Service
Apr 12 10:11:53 scanner scanbm: /usr/sbin/scanbm: dbus match
Apr 12 10:11:54 scanner kernel: [ 3888.935640] usb 1-1.5: reset
high-speed USB device number 4 using dwc_otg
Apr 12 10:11:54 scanner saned: saned (AF-indep+IPv6) from
sane-backends 1.0.27 starting up
Apr 12 10:11:54 scanner saned: check_host: access by remote host:
Apr 12 10:11:54 scanner saned: init: access granted to
Apr 12 10:12:01 scanner saned: saned exiting
Apr 12 10:12:02 scanner systemd:
scanbm at 4-192.168.5.10:6566-192.168.10.3:41450.service: Succeeded.
so I'd say, that my PC is allowed to use the scanner...
But it doesn't... :(
What I see is using tcpdump:
10:11:54.352477 IP 192.168.5.10.8612 > 192.168.5.255.8612: UDP, length 16
10:11:54.352928 IP 192.168.5.10.8612 > 192.168.5.255.8610: UDP, length 16
10:11:54.363284 IP 192.168.5.10.8612 > 192.168.5.255.8612: UDP, length 16
10:11:54.363548 IP 192.168.5.10.8612 > 192.168.5.255.8610: UDP, length 16
Of course the broadcast packets cannot reach my PC on a different network...
I found some HowTo about scanning over different networks, but all of
them refer to pixma, and I don't have this scanner...
I tested it anyway, but (of course!) it does not work...
Can someone help me?
Thanks a lot!
