How does KDE mount my cdrom, any why can't I?

EAD · 03-10-2006, 09:04 AM

Hii, I have add the line "dev/hdc /mnt/cdrom auto noauto,user,defaults 0 0" to my fstab file, when using KDE "My computer" and press on the cdrom icon I get access to the cd after it mount it, but when tryin to do "mount /dev/dvdrw /mnt/cdrom" I get an erorr say that only SUPER user can do this (ROOT), So what am I doing wrong?

If you want to mount the cdrom, you need to be root (System Administrator). You can use the command:

Quote:

su
Password: (type your root password)

and then try again. One thing that I noticed is that you want to mount /dev/dvdrw. The device file /dev/dvdrw is a symbolic link to another device file (for example /dev/hdc). Make sure that /dev/dvdrw is pointing to the device you want to mount, try the following command:

Quote:

ln -al /dev/dvdrw

to check this.

Anyway, you can mount directly the cdrom using the command:

Quote:

mount /dev/hdc /mnt/cdrom

Amm, I know how to do this, but Why can't I allow users that arn't root to do it?
I mean when runing KDE not as a ROOT, I can do it from the My Computer, So how does it do it?

Is it a typo that you once use /dev/hdc and once /dev/dvdrw?

yes I think. so How KDE do it? and How can I do it from prompt?

KDE probably does it using HAL or something that would be running as root. In your fstab line, change 'user' to 'users' and you should be able to mount as a user. Your user needs to have permissions on the mountpoint though.

Also, the forum default text size is quite nice. No need to change that, ever.

Also, stick in a disk and try: mount /mnt/cdrom

(leave out the /dev/dvdrw). Also make sure that you are in the cdrom group.

If I can attach a rider to this question ...

Why might KDE (Konqueror specifically I guess) sometimes not free up access to the CD-ROM, preventing me from unmounting or ejecting the drive?

If anyone wants to line-item veto this question that's cool.

I have the same problem. I guess it happens beacause Konqueror is still accessing the drive folder.

To solve this I leave my /cdrom folder and wait around 3 minutes. Then I can unmount the drive. If I try to early, I can only unmount the drive with a logout, and this is very annoying.

Is there a better way to solve this?

You can do a "lsof | grep cdrom" and see what process accesses the cdrom drive. Sometimes you can see clearly what causes this and end the process.
