SANE

SANE stands for Scanner Access Now Easy. It is the backend system used for scanning on most GNU/Linux systems.

Gentoo

Scanning just does not work most times on Gentoo systems. This appears to be due to strange permission issues. Allowing yourself access to your scanner seems dangerous to some developers for some reason. One simple way to make it work is to add the xinetd service to runlevel default. This then needs a config file.

service sane-port
{
  socket_type = stream
  server = /usr/sbin/saned
  protocol = tcp
  user = root
  group = scanner
  wait = no
  disable = no
}
