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.

Hi, I have suse 10.0 and can not write cd's with K3b. It seems to do everything it supposed to except actully write to the cd. It says its writing but its not. I went to the Novel site and tried the K3b download from there but the result was the same. If I try to erase a cd it locks up the PC, any ideas? Adrian
Try going to the K3B tools menu and run the K3B configuration thingy... it sounds like you either have a permissions problem (ie the user running k3b does not have permissions to write to the device) or it hasn't detected that your CD drive is actually a burner. The configuration tool should help determine (if not fix) which of these it is.
Hi Thymox, I get this message when K3b starts,"cdrdao will be run without root privileges
It is highly recommended to configure cdrdao to run with root privileges to increase the overall stability of the burning process.
Solution: Use K3bSetup to solve this problem."
Q where is this set-up? I looked in Tools there is a link in settings "configure k3b" but can't really find the set up, there is a greyed out button under Misc, sub heading system "check system configuration"
thanks Thymox, when it ran from the command line the only option I got was to alter the write speed,tried that no joy. just says the same when I try, it says 'writing' but doesn't this used to work when I ran suse 9.2 and my pc hasn't changed.

OK, well the error message you're getting says to run the cdrdao programme with root privileges. I was hoping you could use k3b's own tools, but you can still do this manually.
Open a console/terminal.
Become root (use "su" then enter root's password).
Run whereis cdrdao and note where the executable file is (it should be /usr/bin/cdrdao but it might be different).
Still as root, run chmod +s /usr/bin/cdrdao (obviously substituting /usr/bin/cdrdao for where your real cdrdao executable is located, from step 3).
Exit from being root.
Try running k3b again as a normal user and see if it still throws up the same error.
Hope this helps.
(Note: the above action is known as "making the file 'setuid'". It's used so that when the file is run, it runs as the person who owns the file (ie root) rather than the person trying to execute it (ie user).)
Hi Thymox thank you, before I had got your last post I had uninstalled k3b and reinstalled, it seems to be more functional with grayed out boxes now working, however It still wasn't writing. I followed your instructions and got this message on start up:
" Writing device OPTORITE - CD-RW CW4002 is automounted.
Automounting can cause problems with CD/DVD writing, especially with rewritable media. Although it might all work just fine it is recommended to disable automounting completely for now.
Solution: Replace the automounting entries in /etc/fstab with old-fashioned ones."
also the set up button is attached to this i ran it but can't see what to do? is it about adding permissions?
I do not know replace the automounting entries in /etc/fstab, can you advise please, thanks Adrian
here is the debugging output?
