"eject" command only works for root

[Robert Storey]

Dear all,

The "eject" command (which opens the CD tray) works as expected if I run
it as root. But as a common user, typing "eject" on the command line
brings up this error message:

bob@sonic:~> eject
eject: unable to find or open device for: `cdrom'

I took a look at the permissions for "eject":

bob@sonic:~> ls -l /usr/bin/eject
-rwxr-xr-x 1 root root 14332 Apr 25 2001 /usr/bin/eject

Common users can mount/unmount the drive - this is from /etc/fstab:

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

So I'm perplexed as to what is preventing common users from being able
to open the drive with the "eject" command.

regards,
Robert

Dear you,

Does the user have access to the device pointed by /dev/cdrom ? Usualy, the user
has to be a member of group "cdrom".
