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, -T
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 <Editorial comment> AAAAAAHHHHHHHHHHHHHHHHHHHHH!!!!! </editorial comment>

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.

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
