You probably don't want to change the device at all... instead you want to: # chown root.cdrecord /path/to/cdrecord # chmod 4754 /path/to/cdrecord This allows cdrecord to be run only by root and members of the cdrecord group, and to run with the root access, so you don't need to diddle the ownership or access of devices. I think that's in the docs, but it's something I've done for other things, so I just did it. -- -bill davidsen ([EMAIL PROTECTED]) "The secret to procrastination is to put things off until the last possible moment - but no longer" -me -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
