[solved] Can't open directory: permission denied (after DVD mount)

unranked · 2009-02-07 12:37:36

Hello, everybody!

I searched in Google, and here in the Arch forums, but I can't find a solution.
The problem is, when I insert a CD or a DVD, it got mounted, but I can't open it as normal user. I got this:
"Can't open directory: permission denied", or something similar, I just translated.
error message.

~$ groups
disk wheel dbus hal video audio optical floppy storage power users

So, my user is part of the storage group. As root, of course, I can list the contents of the CD/DVD.

I encountered it with thunar-volman, and autofs aswell. Now I have autofs installed based on the wiki article, to me it seems properly.

/etc/fstab:

/dev/cdrom /media/cdrom    auto    defaults,ro,users,exec,owner,noauto    0 0
/dev/dvd   /media/dvd    auto    defaults,ro,users,exec,owner,noauto    0 0
/dev/fd0   /media/fd0    auto    users,sync,noauto,exec,rw    0 0

/etc/autofs/auto.media:

dvd -fstype=auto,ro,nodev,nosuid :/dev/dvd
cdrom -fstype=auto,ro,nodev,nosuid :/dev/cdrom
floppy -fstype=auto,async,nodev,nosuid,umask=000 :/dev/fl

Maybe, I missed something important.

Hal handles permissions and ignores fstab afaik. Read the wiki about Hal. I'm pretty sure some solutions for it are there

Thanks for the advice. I'm done with the wiki, and edited the hal.conf. I changed the user="0" line to my user. But without this, it should work, because my user is in the storage group....

/etc/dbus-1/system.d/hal.conf

<policy user="unranked">
    <allow send_interface="org.freedesktop.Hal.Device.SystemPowerManagement"/>
    <allow send_interface="org.freedesktop.Hal.Device.VideoAdapterPM"/>
    <allow send_interface="org.freedesktop.Hal.Device.LaptopPanel"/>
    <allow send_interface="org.freedesktop.Hal.Device.Volume"/>
    <allow send_interface="org.freedesktop.Hal.Device.Volume.Crypto"/>
</policy>

Still no permission...

i think what i was told to do to fix this issue back when i encountered it was to comment out the lines in hal for the optical drives which i ahvent had a problem with

now im wondering, which is really the better solution?

try to remove the 'owner' option from /etc/fstab

unranked · 2009-02-07 17:48:23

Removed it, but nothing changed, still got the 'permission denied' message...It's getting frustrating.
I removed the autofs, and installed the thunar-volman, reinstalled hal and dbus.
I'm using fluxbox btw, maybe it has something with this issue. But I think it's not. If I mount the CD/DVD in xterm, I still can't open the /media/dvd or /media/cdrom directory, ls can't list it. I'm out of ideas....

checked the permissions to your mountfolder?

unranked · 2009-02-08 08:58:14

They are the default. But here is the output of ls -l before the mount.

$ ls -l /media

drwxr-xr-x 2 unranked root 4096 jan 29 18.12 cdrom
drwxr-xr-x 2 unranked root 4096 jan 29 18.12 dvd
drwxr-xr-x 2 unranked root 4096 jan 29 18.12 fd0

And after the mount.

$ ls -l /media

drwxr-xr-x 2 unranked root 4096 jan 29 18.12 cdrom
drwx------ 6 root root 2048 dec 5 10.16 dvd
drwxr-xr-x 2 unranked root 4096 jan 29 18.12 fd0

I've figured out, that the permissions are somehow messed up. I don't know the reasons yet. So, what if I do a chmod on the /media ?

Edit:

I did the chmod (chmod -R 0777 /media), and nothing changed. I still can't open the /media/dvd directory, when a DVD is mounted.

I just created an another user, which I added to the optical,storage,disk,hal,users groups. With this newly created user I still got the permission denied on the /media/dvd or /media/cd. I can mount the drive, but can't list the contents. Yes, the hardware is ok, because it's new, and it worked in the past, and on other systems.

Edit:

I stopped the hal and dbus daemons (/etc/rc.d/hal stop and dbus stop), as user mounted the drive, and the results were the same.

Commented out the dvd and the cd in /etc/fstab. It was too simple

Not sure if it worked properly or not, but why do I need to edit the fstab file for mounting DVDs?

You can use fstab or not...just don't use both hal and fstab at the same time, or you will run into the above issue.

Somehow I guess it got fixed now. Removed HAL and started using udisks(udev). However, I edited the fstab file as well. Weird enough, it got fixed
