I can no longer see my dvd or cd after I installed libdvdcss.
I used yum for the install.
sudo yum install k9copy
sudo yum install libdvdcss libdvdread libdvdplay libdvdnav lsdvd libdvbpsi

After install /dev permissions = :
lrwxrwxrwx 1 root root 3 2007-12-08 16:20 cdrw -> sr0
lrwxrwxrwx 1 root root 3 2007-12-08 16:20 cdrom -> sr0
lrwxrwxrwx 1 root root 3 2007-12-08 16:20 cdrw1 -> sr1
lrwxrwxrwx 1 root root 3 2007-12-08 16:20 cdrom1 -> sr1

lrwxrwxrwx 1 root root 3 2007-12-08 16:20 dvdrw -> sr0
lrwxrwxrwx 1 root root 3 2007-12-08 16:20 dvd -> sr0

I didn't make any modifications to /etc/fstab.

Any suggestions?

Thanks,

Please post the output of ls -l /dev/sr{0,1}

[mmartine@localhost ~]$ ls -l /dev/sr{0,1}
brw-r----- 1 root disk 11, 0 2007-12-08 16:20 /dev/sr0
brw-r----- 1 root disk 11, 1 2007-12-08 16:20 /dev/sr1

Are you a member of the 'disk' group?
To find out if your user is a member of disk, use 'grep ^disk: /etc/group'

Does not look like it;

[mmartine@localhost etc]$ grep ^disk: /etc/group
disk:x:6:root

There is your problem. Add yourself to the disk group.

I want to thank you for your help here.
I couldn't figure this out the first time and did a re-install.


I added my user name to the disk group.

[mmartine@localhost etc]$ grep ^disk: /etc/group
disk:x:6:root,mmartine

Still have issues with some of the applications.
My current permissions on /dev/sg* are:
[mmartine@localhost dev]$ ls -lart /dev/sg*
crw-r----- 1 root disk 21, 0 2007-12-08 17:56 /dev/sg0
crw-r----- 1 root disk 21, 1 2007-12-08 17:56 /dev/sg1
crw-r----- 1 root disk 21, 2 2007-12-08 17:56 /dev/sg2
crw-r----- 1 root disk 21, 3 2007-12-08 17:56 /dev/sg3

K3B gave error message:

K3b needs write access to all the devices to perform certain tasks. Without it you might encounter problems with CDWRITER - IDE5232
Solution: Make sure you have write access to /dev/sr1. In case you are not using devfs or udev K3bSetup is able to do this for you.

as root :
chmod g+w /dev/sg{0,1,2,3}

(adds write permission to the group)

Still no devices in some applications or file browser.

Any other suggestions?

Thanks,

I noticed the permissions for the block device were different from a later install.

Before libdvdcss install:
brw-rw----+ 1 root disk 11, 0 2007-12-08 22:28 /dev/sr0
brw-rw----+ 1 root disk 11, 1 2007-12-08 22:28 /dev/sr1

After libdvdcss install:
brw-r----- 1 root disk 11, 0 2007-12-08 16:20 /dev/sr0
brw-r----- 1 root disk 11, 1 2007-12-08 16:20 /dev/sr1

The write permission for group and there is a "+" are different.

What is the "+" for and how is this set in chmod?

Thanks again,





Could this be part of the issue.

Give programs accessing scsi (or scsi emulated) devices through pass-through dev (sg*) SUID permissions.
It can be done with K3b setup or manually (as root) by
#chmod 4711 /path/to/cdrecord
#chmod 4711 /path/to/cdrdao
If you are a paranoid and do not want anyone else using optical drives but you, add a group to your system (ie optical) and
#chown rootptical /path/to/cdrecord
#chmod 4710 /path/to/cdrecord
and so on..
Just remember adding yourself into optical group
Hope this helps
ciao

chmod g+w /dev/sr{0,1}

Tried both solutions above with no success.

I think the problems was the umask settings when I installed k9copy and necessary libraries...

Time to punt..

Reinstall and start clean..

Any one know of a good solid set of instructions to get dvd/cd applications working like k9copy etc..?

Thanks for everyones help here...
