CDROM Permissions

[bryansmith]

Hey everyone,

I seem to be having some odd problems with my CDROM and permissions. When ever I want to use it to rip/play music (I haven't really tried data cd's yet), I have to do a quick 'chmod 666 /dev/cdroms/cdrom0' first and then I can use it properly. If I don't, it is as if there is no disc present or there is a disc error. My question then is how do I have it so I don't have to chmod my CDROM every time I turn on my laptop? I know it can be done because I have never had this problem with any other distros.

In case you need it, here is the contents of my /etc/fstab:

#
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0
tmpfs                  /tmp          tmpfs     defaults            0      0
usbfs                  /proc/bus/usb usbfs  defaults            0      0

/dev/cdroms/cdrom0     /mnt/cd   iso9660   user,noauto,unhide   0      0
/dev/cdroms/cdrom0     /mnt/dvd  udf       user,noauto,unhide   0      0
/dev/floppy/0          /mnt/fl   vfat      user,noauto             0      0

/dev/discs/disc0/part2 swap swap defaults 0 0
/dev/discs/disc0/part3 / reiserfs defaults 0 0
/dev/discs/disc0/part1 /windows/C ntfs    nls=utf8,umask=0222 0       0
/dev/discs/disc0/part5 /windows/E vfat    iocharset=utf8,umask=000   0       0

Thanks in advance,
Bryan

this may sound a bit obvious, but, have you added yourself to the cdrom group?

[bryansmith]

I wish it was that easy. Unfortunately, there is no cdrom group. Should I try creating one and adding myself to it?

Bryan

[AlexK]

hmm, no cdrom group? I"d guess you could try creating the group, but I have no idea how to tell the system that that particular group can access the cdroms.

[bryansmith]

As we had both guessed, this didn't work. Any more ideas?

Unfortunately I have no elegant ideas as to how to fix the problem. A cheap hack would be to execute chmod 666 /dev/cdroms/cdrom during bootup.

[bryansmith]

I was thinking of that but I was wondering if there was another way.

Thanks for the help.

This doesn't look right...

It's devfs, not udev. The weird thing though is that my grub config file has to be udev (since I upgraded from linux 2.6.10 to 2.6.13.4) but my /etc/fstab is devfs and works fine. I could try changing the cdrom to udev. Thanks for the idea.
