Hi All,
Okay, now this is "scary".
Both xsane and Simple Scan work locally.
I can not get saned to work, UNLESS, I edit /etc/group
and add the following to root
root:x:0:saned
Without it, I get
$ xsane net:localhost:epkowa:interpreter:001:007
Access to resource has been denied
Now what am I doing wrong? Must saned have root privileges?
CUPS doesn't need it.
Many thanks,

Followup:
To correct this, add
# /usr/lib/udev/rules.d/70-saned.rules
ACTION=="add", ENV{libsane_matched}=="yes", GROUP="saned", MODE="0660"
to
/usr/lib/udev/rules.d/65-sane-backends.rules
I just opened
https://bugzilla.redhat.com/show_bug.cgi?id=1554032
to fix this.
I have been troubleshooting this since November

A fun command:
# rpm -qf /usr/lib/udev/rules.d/65-sane-backends.rules
sane-backends-1.0.27-12.fc27.x86_64
Note: you have to reboot to get this to take:
$ scanimage -L
device `epkowa:interpreter:001:003' is a Epson Perfection V300
flatbed scanner
device `net:localhost:epkowa:interpreter:001:003' is a Epson
Perfection V300 flatbed scanner
$ xsane net:localhost
worked
Unplugging and replugging the scanner:
$ scanimage -L
device `epkowa:interpreter:001:008' is a Epson Perfection V300
flatbed scanner
device `net:localhost:epkowa:interpreter:001:008' is a Epson
Perfection V300 flatbed scanner
$ xsane net:localhost
worked
In my situation I have not put any entries in /usr/lib/udev/rules.d to
get the scanner on the multi-function device working over the network
(I have an Epson Expression ET 3700 continuous flow ink device).
My first step in getting the scanner working was to look at
/etc/sane.d/epson.conf and /etc/sane.d/epsonds.conf
(/etc/sane.d/epson2.conf seems to be for usb connected devices). These
2 conf files have 'net autodiscovery' already specified, but that was
not enough to detect the scanner and neither was adding 'net
<ip-address>' (the ip address of the device as set on the device).
Having already downloaded the printer driver for cups I went to the
same site and downloaded Epson's Imagescan package and installed it.
That package installs 2 conf files /etc/imagescan/combo.conf and
/etc/imagescan/imagescan.conf and a scanning tool called Imagescan.
This installation was still not enough to get the scanner working with
Imagescan. To get it working I had to uncomment the 3 device
statements (I think they were commented), change to model entry to my
device name and change the ip address to the address I set my device to.
Having done these changes Imagescan was able to find the device and
after a reboot (I didn't try Xsane until several days later) so did
Xsane. To test Xsane I don't have to unplug the device from the
ethernet connection to the router, just turning the power on and off
on the device is enough to test Xsane's ability to see the device.
Scanimage -L gives me the following output:
scanimage -L
device `imagescan:esci:networkscan://192.168.1.20:1865' is a Epson
ET-3700
xsane (without any parameters)
worked
xsane (with the device powered off)
'No devices found'
xsane (with the device powered back on)
worked
My setup is a bit different to yours, from your output it looks like
you have the scanner connected to your computer via usb and you are
trying to share that over the network, whereas in my case my device is
actually network connected and I am trying to get the multiple
computers and Android devices talking to it.
regards,
Steve
With Xsane working the issue I need to resolve now is how to get Xsane
to provide the different resolutions the scanner is capable of.
Imagescan provides the resolution selection capability, but the
documentation of Xsane says the Sane backend must provide the resolution
specifications, but there isn't a definition in the Sane backends for
this device, other than entry in /etc/sane.d/dll.d to register imagescan.
regards,
Steve
