Only root can automount CD drive and USB thumb drive

[km4hr]

Nothing happens when ordinary users plug in a USB thumb drive or insert a CD into CDROM drive. Works fine for root. After root mounts the drives then all users can use them. How can I enable mounting/unmounting by all users?

What version of Linux are you using?

I'm using CentOS 5. A recent version. CD's made about 3 months ago. Now let me see, there must be some command to find the exact version. Hmmm.

To find out the version try

cat /etc/redhat-release
CentOS release 5.2 (Final)

you only get a popup notifying you of new media if you are logged in as root ?

I've just tried this on my centos server and as a user I was getting an error mounting the drive, although there is a chance this is because I am logged on via remote desktop but I dont think so.

Looking at /etc/fstab I couldnt see any entry for the cdrom drive, so I edited my /etc/fstab file to include the line

/dev/hdb /media/cdrom udf,iso9660 user,noauto,exec,utf8 0 0

you probably want to check that /media/cdrom exists and if it doesnt

mkdir /media/cdrom


if you dont know what device the cdrom drive is on you could try
dmesg | grep CD

which should return something like

hdb: AOPEN COM5232/AAH, ATAPI CD/DVD-ROM drive
hdb: ATAPI 52X DVD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33)

which shows mine on hdb.

Please be very very careful you dont change anything else in fstab or you may find your system will not boot, I dont know for sure that this is the suggested way to get the functionality you want under centos but it should work.
