grip cannot even see CD-ROM


Hi all,
Earlier today I noticed that my computer (Slackware 9.0) was somehow playing the audio CD which I had in the cd-rom. I hadn't initiated the playing of the disk, and tried ps -A to see what was playing, but I couldn't see any audio program. This remains an unsolved mystery, and I only mention it as proof that I apparently can see and read audio CDs.
Now, I'm trying to use grip to rip the CD, and am not having any luck at all. I can't mount the drive with the audio CD in there, and can't read the CD from Xmms. Starting grip presents me with a blank interface. I have /dev/cdrom set as grip's CD-ROM device, and nothing in Generic SCSI Device, although I've tried changing permissions on /dev/scd0 and entering that as the SCSI Device. All other posts I've seen both on this site and others involve being able to read the CD but not rip it, whereas I can't even see it

My /etc/fstab is as follows:
bash-2.05b# cat /etc/fstab
/dev/hdb1 / ext2 defaults 1 1
/dev/hdb5 /home ext3 defaults 1 2
/dev/hda1 /mnt/mandrake ext3 defaults 0 0
/dev/hda6 /mnt/server ext3 defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

If anyone has any ideas, I'd be grateful!
Thanks

Can grip see the CD when you are root? I think you need to add users to you /dev/cdrom line.

Add your username to the cdrom group: Open /etc/group with your favourite editor, find the line for the cdrom group and add your username after the last colon (the ":" character). This is a comma-separated list of usernames. Here's my group entry for the cdrom group:
cdrom:x:24:hw,jenny,aw
Log out and then in again for the changes to take effect.

You may also have to change the permissions on the devices /dev/cdrom point to (be it /dev/scd0 or whatever) to allow group members to do whatever they want: chmod g+rw /dev/scd0 .

along with what has been suggested about adding users to the cdrom group, i actually also had to enable the setuid bit for cdparanoia for grip to rip and encode.

your cdrom is capable of playing audio without a program
go into your bios and press the play button on your cdrom you'll find that this is accurate
