Mount CDROM

PMP · 05-26-2009, 01:54 AM

Hello,
My requirement is that i want to set up something like ..

A non root user should be able to mount the cdrom device
Able to copy the contents on the CD.

The solution i have thought of is giving sudo rights to the user but in that case i need to give sudo on cp as well,

What will the best way to achieve it.

Hi there,

What distribution are you using??? I thought with any newer distro, the automount was de facto. Have you tried just putting a CD into your rom???

Cheers

I am using RHEL 5.2
Follwoing is my fstab entry

/dev/cdrom /mnt/cdrom auto noauto,owner,kudzu,ro,nosuid,nodev 0 0

I dont want it to be auto mount

Not sure what "kudzu" does in your options list, but you probably want to change "owner" to "users" (see the fstab man page for more details).

Hi there,

You might want to update the fstab after changing entries. The best solution for you would probably be to reboot your machine. In the reboot process, the fstab is updated and you should be able to mount the CDROM.

permissions on /bin/mount should be 4755.

Try changing "owner" to "user", not "users" (see man mount). And maybe remove "kudzu" since that autoconfig may do some weird things.

Hi,

I don't use Fedora but your users should be in the proper 'groups'.

If i change the permission of mount to 4710 i am unable to run cdrecrord

It gives the following error, any idea on this ??

cdrecord: Resource temporarily unavailable. Cannot get mmap for 4198400 Bytes on /dev/zero.

4710 are awkward permissions (rwx--x---). Do you have any reason for doing so? Because then programs using mount will not work.
