Any suggestion would be most appreciated.

stop the firewall at discovery time (setup)?

jdd

That worked for a certain time. I systemctl stop(ped) firewalld.service and reran scanimage -L. It found the scanner. Then, since I don't really want to leave the firewall stopped, I started it again. Right after that scanimage kept finding the scanner, for some to me obscure reason. After a few minutes, though, another scanimage -L gives me:

"No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages)."

I tried to open port 80 in the firewall, because that appeared to be the port where "airscan-discover -d" found the scanner before, but it didn't work. Is there a permanent solution without deactivating the firewall altogether? Amazingly enough the same device works fine as a printer.

Thank you.
