Here are some details.
Linux shuttle 5.4.2-desktop-1.mga7 #1 SMP Thu Dec 5 17:40:00 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
(from "scanimage -L" on the server) device `genesys:libusb:002:002' is a Canon LiDE 110 flatbed scanner
scanimage (sane-backends) 1.0.27; backend version 1.0.28
Scanner works locally on server (192.168.1.105), but does not work from a desktop on the LAN (192.168.1.106). I removed (x)sane from the server to test without it. It made no difference - the desktop still can't find the scanner.
I am unable to connect to port 6566 on the server via telnet. Connection closes immediately:
- Code: Select all
# telnet shuttle 6566
Trying 192.168.1.105...
Connected to shuttle.
Escape character is '^]'.
Connection closed by foreign host.
scanimage -L on the desktop fails to see the scanner
saned.socket is running:

# systemctl status saned.socket

The only thing I notice that seems questionable is an undefined symbol that shows up in the journalctl readout from the server when I try to connect to the scanner from the desktop:
- Code: Select all

I can't think of anything else to check. Does anybody here have any suggestions?
Thanks for the time and attention.
