Unlike the case with a network capable scanner i.e. the scanner connected directly to the network,
these are the settings for sharing across a network scanner connected to a computer via USB.
As root, on *server*:
1. Create 'saned' user & group
# getent group saned >/dev/null 2>&1 || groupadd -r saned 2>&1
# getent passwd saned >/dev/null 2>&1 || useradd -r -l -g saned -d /dev/null -s /sbin/nologin -c "SANE network daemon" saned >/dev/null 2>&1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2. Create template unit configuration service file
/etc/systemd/system/saned@.service
[Unit]
Description=SANE network daemon
Requires=saned.socket
[Service]
ExecStart=/usr/sbin/saned
User=saned
Group=saned
StandardInput=socket
Environment=SANE_CONFIG_DIR=/etc/sane.d
# Debug:
#Environment=SANE_DEBUG_DLL=128 SANE_DEBUG_NET=128
[Install]
Also=saned.socket
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3. Create unit configuration socket file
/etc/systemd/system/saned.socket
[Unit]
Description=saned incoming socket
[Socket]
ListenStream=6566
Accept=yes
MaxConnections=1
[Install]
WantedBy=sockets.target
~~~~~~~~~~~~~~~~~~~~~~~~
4. Create udev rule file
/etc/udev/rules.d/70-saned.rules
ACTION=="add", ENV{libsane_matched}=="yes", GROUP="saned", MODE="0660"
~~~~~~~~~~~~~~~~~~
5. Apply udev rule
# udevadm trigger --action=add
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
6. Add clinet name, client IP address, or IP subnet
to saned configuration file, within 'Access list' section.
In this example clinet IP address is used
/etc/sane.d/saned.conf
192.168.1.2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
7. Firewall - open SANE control port 6566/tcp

As root, on *client*:
1. Add server name or server IP address to net backend configuration file,
within 'saned hosts' section.
In this example server IP address is used
/etc/sane.d/net.conf
192.168.1.1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2. Fire up your favorite frontend,
xsane, scanimage, simple-scan, skanlite, ...

Tested and works.
