This is my configuration according to penguin-breeder.org:
/etc/services
  sane-port      6566/tcp     # SANE network scanner daemon
/etc/xinetd.conf
  service sane-port
  {
        socket_type = stream
        server = /usr/sbin/saned
        protocol = tcp
        user = saned
        group = scanner
        wait = no
        disable = no
  }
permissions are:
 0 -rw-rw----  1 root scanner 57 Jan 11 21:08 /proc/bus/usb/001/002
scanimage -L on server
 device `niash:libusb:001:002' is a Agfa Snapscan Touch flatbed scanner
telnet localhost 6566
  Trying 127.0.0.1...
  Connected to localhost.
