Mount a cd image as a user

Vlad420 · 01-31-2011, 11:01 AM

Sorry if this has been answered before somewhere else but all I have been able to find is how to add things to fstab.
Is there a way to allow a user to use the mount command without adding a specific entry to the fstab
-or-
Is there sompthing I can add to allow a user to mount anything to a specific point such as a private folder in their home directory
I am currently using slackware 13.1

To mount a cd-image,.. you would:

Code:

mkdir /mnt/cdrom
mount -o loop redhat-6.iso /mnt/cdrom

@szboardstretcher: Those commands will not let a normal user mount a loopback image. I'm pretty sure that you would have to edit /etc/sudoers for mounting images on loopback.

you need to use sudo for these two commands to work if you are not root

Code:

sudo mkdir -p /mnt/cdrom
sudo mount -o loop redhat-6.iso /mnt/cdrom

the -p switch to mkdir creates the parent directory's as well

If I remember well I have configured this in the past adding the user to the disk group (yes, sometimes I'm just rude

)

Code:

$ ls -la /dev/loop*
brw-rw---- 1 root disk 7, 0 gen 31 08:55 /dev/loop0
brw-rw---- 1 root disk 7, 1 gen 31 08:55 /dev/loop1
brw-rw---- 1 root disk 7, 2 gen 31 08:55 /dev/loop2
brw-rw---- 1 root disk 7, 3 gen 31 08:55 /dev/loop3
brw-rw---- 1 root disk 7, 4 gen 31 08:55 /dev/loop4
brw-rw---- 1 root disk 7, 5 gen 31 08:55 /dev/loop5
brw-rw---- 1 root disk 7, 6 gen 31 08:55 /dev/loop6
brw-rw---- 1 root disk 7, 7 gen 31 08:55 /dev/loop7

but that is definetely a bad idea.

here you can find a pair of good advices

I would say thats probably my best option but wow thats gonna take a while to figure out

Yes, there is, but there are good reasons for fstab, it keeps it short & safe, of course if you want to mount anything anywhere, I would suggest editing sudoers, using visudo.

Code:

$ visudo
{username} ALL = /sbin/mount, /sbin/umount

or if you don't want to type in your passwd everytime

Code:

{username} ALL = NOPASSWD: /sbin/mount, /sbin/umount

from that point you can mount anything anywhere

Code:

sudo mount ...{anything}...{anywhere}

That sounds good but just so I'm clear on this I need both the username and ALL in the line not one or the other right?

a little less elegant, but you could try fuseiso.

gnashley · 02-02-2011, 08:55 AM

You could also use archivemount.

linus72 · 02-02-2011, 09:21 AM

I use Isomaster
http://www.littlesvr.ca/isomaster/

get it from slackbuilds or sbopkg

mountlo should work. I tried it a few weeks ago.

Hangdog42 · 02-02-2011, 11:47 AM

I use pmount to mount as a normal user. There is even a Slackbuild for it.

Yes, that's correct, you need both, username and ALL (ALL represents host, but you can use hostname instead).
