Hi guys,
i am into a problem these days and required some feedback on it. I am using linux redhat 9 on the network machines and i want to forbid users to use usb storage device for data copy. The users on the system does not have root access but they can mount the usb device using 'sudo'. I stripped of the SUID bit from the mount command and blocked the 'mount' in 'visudo' but now they are unable to mount cdrom. Is there a way they can mount the cdrom but cannot mount the usb devices. I want to do it using open source tools and tehniques.
