Virtual Media in a Linux Environment

Following is important information for Linux
media.
Root User Permission Requirement
Your virtual media connection can be closed if you mount a CD ROM
from a Linux client to a target and then unmount the CD ROM. The
connection also closes when a floppy drive has been mounted and then
a floppy disk is removed. To avoid these issues, you must be a root user.
Permissions
Users must have the appropriate access permissions in order to connect
the Drive/CD-ROM to the target. This can be checked using:
guest_user@administrator-desktop:~$ ls -l /dev/sr0
brw-rw----+ 1 root cdrom 11, 12-03-2010 11:52 /dev/sr0
In the above example, the permission must be changed to allow read
access.
On a system that supports ACLs in its file utilities, the ls command
changes its behavior in the following way:

For files that have a default ACL or an access ACL that contains
more than the three required ACL entries, the ls(1) utility in the long
form produced by ls -l displays a plus sign ( + ) after the permission
string.
This is indicated in the example provided here for /dev/sr0, use getfacl –
a /dev/sr0 to see if the user has been provided access as part of an ACL.
In this case they have and are therefore able to connect the cd-rom onto
the target even though the output of the ls –l command may indicate
otherwise.
