BTW, I note that the Ubuntu guide you referred to mentioned using the following config directives in the saned.socket unit file
Code:
# Defaults for the saned initscript, from sane-utils

# To enable under systemd please read README.Debian
# Set to yes to start saned under SysV
RUN=no

# Set to the user saned should run as
RUN_AS_USER=saned
I don't use that (and it's not mentioned in 'man saned' either), so my /etc/systemd/system/saned.socket looks like this
Code:
[Unit]
Description=saned incoming socket

[Socket]
ListenStream=6566
Accept=yes
MaxConnections=1

[Install]
WantedBy=sockets.target

Thank you so much for trying to solve this. The 'funny' thing is that I also made it work some time ago on my older PC, and it worked immediately with no issues...
There is a chance that this relates to the particular sane-backends version (sane-backends 1.0.26git) in use on your system I guess. Are you able to upgrade the host perhaps?

I changed saned.socket by removing the first lines, now it's exactly the same as yours, but still no luck.
I also updated the host to 1.0.27 via github, nothing changes.
It's very interesting that you get the same behaviour I have using StandardInput=null. I'm using StandardInput=socket, as you do, but it may be that, for some reasons, this option is not set, and the issue is due to that...

What happens if you remove (or comment out) the User= and Group= directives?

burkina76 03-11-2018 05:48 AM
Nothing...

Does /etc/default/saned exist? If so, what does it contain?

burkina76 03-11-2018 06:34 AM
Well, I don't know what happens, but now it works...
Looking at the log, now the correct IP appears asking access, and the access is granted. I can use the scanner from the client.
The only thing that occurs to me is that I didn't perform a reboot after the upgrade to 1.0.27. After the reboot, now it seems to work, it may be thanks to the update. At least, this seems to me the only possibility.
I will test it in the next few days, and let you know if it stops working again.
Thanks a lot for the help, I was completely stuck...

Glad to have walked with you on this one, and good to read of you success with this finally! :)
