Storage partition, PERMISSIONS

[justin_c18]

All even I've tried to setup proper partitions for my storage partition that will serve my dual boot laptop. The partition is on the same drive I dual boot with. I can't seem to get figure out how to get permission to allow user(with root) to get read/write/execute enabled.

I only want the user and root to have full permissions on the partition. I don't want others to read/write/execute within it.

/etc/fstab is

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# /dev/sda2
UUID=6ccf4b83-d7ad-472d-a32f-3b70e3f74c77 /               ext3    relatime,erro$
# /dev/sda1
UUID=857cd650-3fcc-4cf8-8b50-4bbbdaee26a2 none            swap    sw           $
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
/dev/sda4 /media/Storage ext3 defaults 1 0

What would be nice is to have a group enabled for both user and root to enable what I want so no one else can see or use/ copy/ paste into it.

stat /dev/sda4 reads:

  File: `/dev/sda4'
  Size: 0         	Blocks: 0          IO Block: 4096   block special file

stat /media/Storage reads:

Basically when I formatted the drive, I 'sudo mkdir /dev/sda4 /media/Storage'. Not sure if is messing anything up.

It's obvious I need help. and all the help I get is much appreciate.

Thank you in advance.

First, I would edit /etc/fstab and change the entry for /dev/sda4 from what you have right now to this.

/dev/sda4 /media/Storage ext3 defaults 0 2

Now, if you want to write to /media/Storage without root privilege, just change the ownership of /media/Storage from root to your login name, assuming your login name is justin.

sudo chown -R justin:justin /media/Storage
sudo chmod 700 /media/Storage
ls -la /media

Now, only user justin and root can read or write to /media/Storage. Nobody else can even take a peak it there.

First off, thank you very much for that. I've been looking to do that same thing all day. And, it was obviously in to those two last numbers you told me to change.

ls -la /media shows

drwx------  5 justin justin 4096 2009-03-01 22:41 Storage

For a better explanation, what did the 0 2 do?

And second, when I create a folders, or files, right click in nautilus, properties, and permissions - the said files don't retain the same permissions as the Storage permission. Does that make sense, and does it matter? Can I change the permissions to be the same as the partition permissions once created, or moved into the partition?

Thanks very much
Justin

HI Guys, I'm a new Ubuntu user (one week now and I like it a lot) but I have also a problem with permissions for my FAT32-drive that I share with WindowsXP.
I managed to mount the disk automatically and changed /etc/fstab. Than I tried the command

sudo chown -R justin:justin /media/Storage

But I only get messages like 'operation not permitted' for every file on the disk... When using

ls -la /media

, I see that only root has the right privileges to write

[soapwater]

Whoop, and now I don't have permission anymore do view the files, to mount or unmount... How to fix this?

How did you mount your fat32/vfat partition through /etc/fstab? Remember, fat32/vfat doesn't play well with permissions/ownership stuff so chmod/chown doesn't do any good.

Post the output of these commands from a terminal

sudo fdisk -l
cat /etc/fstab
df -h

Once you've set the permissions for /media/Storage to 700, it doesn't matter what kind of permissions you have for files and directories under it, nobody is able to view them.

Just log in as another user and see what happens when you run this command from a terminal.

cd /media/Storage
-or-
ls -la /media/Storage

I don't like hijacked posts because not only did it not answer all the proceeding questions, but different filesystems are different.

Write and ask in your own post for more clarity.

So, now whenever I restart the computer, permissions to the files and folders inside my Storage partition are not correct. My permissions are gone, and I can't edit the folder, or anything inside it.

How can I fix it so justin and root have permission over the folers and files? I can't go into properties in nautilus and change the permissions, but that's not what I want.

Thanks.
