Virtual Media In A Linux Environment - Raritan Dominion KX II User Manual

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.
Note: Mapped drives from Mac
mounted onto connected targets. This applies only to KX II 2.4.0 (and
later) and LX 2.4.5 (and later), which provides support for Mac and Linux.
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.
