Why do you use the "saned -d" trick? Doesn't it work with running
saned by xinetd?

What happens if you don't do this and just use the saned binary?

In principle, this should work. Try to remove the "| tee ...", this

The second one should work, but no log will be created.

The third one can't work, because -d tries to listen on the SANE port
which is occupied bei xinetd.

This usually means everything is ok.
When your saned is installed correctly you should be able to see your
scanner with scanimage -L on your Linux computer twice. Once directly
and once via net:localhost. You must uncomment "localhost" in net.conf
for this test.

Doesn't help for saned if tcpwrappers aren't used.

If it's accepted, it should work. I don't know what's going wrong here.
