1) The permissions: To change the permissions on a device you need to edit /etc/fstab.
If you want all users to be able to mount/umount the drive, the line would be something like this:

/dev/cdrom /mnt/cdrom iso9660 noauto,owner,user,ro 0 0

2) The name: /dev/cdrom is just a symlink. It should be linked to something like /dev/hdd. You can change it to /dev/dvdrom if you want, but it doesn't really matter

well the line looked exactly like that already? when I start ex. kscd it says;

CD-ROM read or access error
Please make sure you have access permissions to:

/dev/cdrom

as if i logg in as root and start kscd it just playes the cd..., could it be something else?

Hm, I'm kind of stumped then. It could be that you have to be part of the same group as cdrom. Just to test, you might try changing its group/adding yourself to the group.

Other than that, I have no ideas.

hm... there is no cdrom group? Another thing with this whole deal is, that as root (being able to play cd in kscd) if I "cd /mnt/cdrom/" and do "ls" it's empty? but there's a cd in playing at the same time in kscd? and if i open xmms and want to add the content of the CD xmms doesn't see any files in /mnt/cdrom....? I don't get it..

Yes, you don't actually mount audio cds to play them. Its the same for dvds and other things of the like.

Have you run kscd from the console and seen what error messages it gives you? I'm sure you just have to be a member of some arcane group..

I ran it from the console and the message was this:

kdecore (KAction): WARNING: KAction:

lugAccel(): call to deprecated action.
kdecore (KAction): WARNING: KAction:

lugAccel(): call to deprecated action.

I have no idea of what this means though...?

andrew001 · 12-27-2003, 06:45 PM

Eh, the probably isn't what we're looking for. That error would just mean that kscd is interacting with kdecore in a bad way but (almost certainly) has nothing to do with your problem.

Is that all that comes up on the console when you try to open up a cd as a non-priviledged user.

yepp, that's it and a window with the following mess..

"
CD-ROM read or access error
Please make sure you have access permissions to:

/dev/cdrom
"

any suggestions?

teona · 12-28-2003, 11:52 AM

I still have this major problem, isn't there anyone how's got any other ideas on how to get user account to access the cdrom? ...

need YOUR help over here...

andrew001 · 12-28-2003, 01:25 PM

Try adding yourself to the group 'disk'. If this is a dvdrom, it should be something like /dev/cdrom is symlinked to /dev/hdd. /dev/hdx is always a member of group disk.

The permissions on /dev/hdx should be rw-rw----. You could change them, or just add yourself to group 'disk' in /etc/group.
