sudo apt install sane
/etc/sane.dand edit the
saned.conf. Add the following line to allow scanning from your network:
And you should be good to go.
On the client side installation and configuration is even easier. Just install sane and maybe simple-scan (great application!), afterwards edit the
/etc/sane.d/net.conf and add (e.g. as a last line) the name or IP address of your server.
That's is, now you're good to go!
