Mounting optical platters

[Richard Ray]

I have an optical jukebox on a machine running HP/UX 10.20.
Is there a way to let users other than root mount platters?

Hi


try www.software.hp.com

download sudo

allow mounts via that

Not if they are mounted to a filesystem, because only root can do such. You could provide sudo or a setuid script (as root) to do such.

Hi,

Two programs you may use, one for mounting,
one for unmounting. This for mount/unmount
of CD, so you may have to do some changes.
Device-file and mount-point are hardcoded,
but you may rewrite the program to have
them take this as arguments.
You will however have to consider the
securityrisk involved. After all there is
a reason why you normally have to be root
to mount/unmount
/* Program that gives a regular user the ability to mount a cd.
. Compile the program
. Make root the owner of the executable.
. chmod 4755 executable
