Description Michael Wardle 2003-03-22 10:45:02 UTC
Description of problem:
I have an IDE/ATAPI DVD drive on /dev/hdc and an IDE/ATAPI CD-RW drive on
/dev/hdd.  Red Hat Linux automatically configures the CD-RW drive as an
IDE-SCSI device by adding hdd=ide-scsi to the kernel boot parameters.
For consistency and improved performance, I have also configured my DVD
drive as an IDE-SCSI device by adding hdc=ide-scsi to the kernel boot

After rebooting, the SCSI devices in /dev are given the following
brw-------    1 michael  disk      11,   0 Jan 30 21:24 /dev/scd0
brw-------    1 michael  disk      11,   1 Jan 30 21:24 /dev/scd1
crw-rw----    1 root     disk      21,   0 Jan 30 21:24 /dev/sg0
crw-------    1 michael  disk      21,   1 Jan 30 21:24 /dev/sg1

To be able to consistently and completely use the DVD drive as a SCSI
device (in particular to be able to rip music from an audio CD in the DVD
drive using Grip), /dev/sg0 also needs to have permissions similar to

Given the devices are owned by the user "michael", the user who is
currently logged in to a local X session on the console via GDM, I
am filing this bug under GDM, assuming it is what has modified the
permissions on the SCSI devices, but has not also modified the
permissions on /dev/sg0.

Comment 1 Michael Wardle 2003-03-31 03:53:33 UTC
It seems like this is handled by pam_console in /etc/security/console.perms.
Changing component accordingly.


Comment 2 Tomas Mraz 2004-09-21 13:22:00 UTC
You need to read the man console.perms and change it accordingly to
your  modified configuration.
