[sane-devel] permissions for parallel port scanners

[Oliver Rauch]

Hello.

Now we have some parallel port scanners supported by
sane and I get several messages with questions how
the people can access their scanner as user.

We need a better way to handle these scanners.
It really is dangerous to run the frontends as
root or with suid=root.

So I want to ask all authors of backends that support
parallel port scanners to work out a common way
(sanei_parallel_*) to talk as user to the scanner.
These sanei_parallel_* routines should run on
as much systems as possible (not only linux!).

Please also add a text to the manpage of the
backend how the scanner can be used by user
and also point out how dangerous it is with
suid=root!!!

An other way would be to connect via sane-net/saned
to the local machine but as far as I tested that
still does not work very well due to a bug in sane-net
or saned.

Bye
Oliver
