Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I was following along the sane man pages for my Mustek 1200CP parallel port scanner. (P4/1.7GHz, 1GB RAM, Fedora Core 3) So far, so good. The only problem is, I can only scan something if I am signed on as root or have done an su and entered my password. Even then it whines about "Do you REALLY want to scan this as root because you're risking your firstborn child" or something like that. If I try to use gimp or any of the GUI widgets as a regular user, I am out of luck. It says it can't find any scanner devices.
All this leads me to think this is a permissions problem (isn't it always a permissions problem?). When I "Click Here to Find Similar Threads" the solution seems to be "su first, then it works". Is there an elegant solution or am I stuck with the nag box?
Should I change the permissions on everything with "sane" in the name? Could it be as simple as one directory? I don't care, I just want this scanner to work with a minimum of hassle.
Despite extensive searching, I cannot find a scanner group.
Is there something else I can do to allow normal users to access the scanner? (Ideally, without the downtime associated with updating my distro...) Currently, only root or users with the su password can use the scanner.
Look, this is only one half of solution. In order the scanner group to work the scanner device must belong to this group. In a modern distro it is done using udev. Again, have no clue how to do it in FC3. Is udev used in FC3? If not you may try to chown the scanner device.
Thanks for all your help! Being halfway there is very good news indeed!
Yes, udev exists. Unfortunately, as usual, the man pages were more confusing than helpful. I edited /etc/udev/permissions.d/50-udev.permissions. I found the following lines:
# scanner devices
The numbers at the end appear to be permissions. I changed 0600 to 0777 for the two lines shown, but this still doesn't help my scanner problem. What else should I try? Do I need to change the printer permissions, too, since this is a parallel port scanner?
