I can't reproduce this bug with pam-0.77-55 If you look at those devices (/dev/fd0, /dev/hd? which is the cdrom device), are you owner of them if you are logged on the console? What is the contents of the /var/run/console directory? I would be much happier to know what really caused the problem and which changes made it to vanish but indeed with my current test setup "owner" in /etc/fstab is sufficient. Many things were modified in the meantime but yes - a month ago I was an owner of devices in question, IIRC, and this still was of no use. On the first attempt to mount a CD by a non-root I got though "/mnt/cdrom already mounted or a wrong file system" but I could not repeat that after a subsequent mount by root or after a reboot. A hiccup in a driver? Maybe; although I tried that a few times before an attempt from a root account, and results were the same, so it does not sound like timing. Still I do not know how to reproduce that. |
Description of problem: Not entirely sure if pam is really the culprit here but it owns all relevant config files. Still the recent kudzu-1.1.79-1 may be involved here. I do not know when this really started. With the only one active login on the whole machine, i.e. me, I get: $ mount /mnt/cdrom/ mount: only root can mount /dev/cdrom on /mnt/cdrom A corresponding line in /etc/fstab has these in options field: udf,iso9660 noauto,owner,kudzu,ro After changing "owner" to "user" there are no problem with mounting cdrom from a non-root account but the former used to work just fine and in some setups may make a difference. The same goes for floppy (and even if I can mount /dev/floppy then 'mdir a:' gives "Can't open /dev/fd0: Permission denied"). It should be noted that even if "owner" is used and 'mount /mnt/cdrom' does work then 'strace mount /mnt/cdrom' ends up with 'write(2, "mount: must be superuser to use "...' but this can be a property of strace. Version-Release number of selected component (if applicable): pam-0.77-54 How reproducible: 100%
