  All backends that use /dev/port or inb/outb access must be run from a
  program as user root (at least with newer kernels). One way is to use
  the frontend as root or suid root the frontend but that's not
  recommended and xsane warns explicitly if it's run as root. Another
  way is to run saned as root and access the scanner with a frontend as
  normal user via the net backend.

  No, saned is in sane-backends.

  If you don't want to use xsane as root you need saned.

  I may be wrong but I think that this is connected to using tcpd (tcp
  wrapper) together with the services (e.g. in.telnetd).

  Bye,
