umount problem


Dear All:
Below is my fstab file:
Label=/ / ext3 defaults 11
Label=/backup /backup ext3 defaults 1 2
Label=/boot /boot ext3 defaults 1 2
Label=/usr /usr ext3 defaults 1 2
Label=/var /var ext3 defaults 1 2
/dev/sda5 /swap swap defaults 0 0
/dev/hda1 /cheng ext3 noauto 1 2

Why i login as user and i still can access to /cheng directory?This is no mount during the boot time.

How to make other user unable to access and view this /cheng directory?

chown root /cheng
chmod go-rx /cheng

Now only root can see /cheng directory.

If the /dev/hda1 is no mounted,what will be happen?
Depends on what kind of data is stored on it.

What i want is when the user log in his/her username,then he/she only can access to their home directory,they can not go to other directory.How to do it?
In that case you have to set read,write permisions for the /home folder of each of the user. I think you have to do it manually for each user.can it be done automatically? I do not know. while adding user i thimk you can set the permissions.

Ok... I've merged the three posts about the same topic together. Please do not post the same question over and over again, it is a violation of our forum rules.

The last post you quoted is incorrect.
You DO mount/unmount file-systems .. file-systmes are created on disk partiontions so one may think you
are only mounting partiotions .. but you are mounting the file-system written into a partiontion..
you can create a file-system in a file and mount it too .. actually you can mount as many such fs ..

now that said .. the example you have given (of your fstab) ..
you will have to be root to mount this file-system .. for any user to be able to mount it .. you will have to
include the world "user" in the options ..

Your concern about privacy even from root can only be addresssed by encryption .. the suggestion of creating a group
and making the fs accessible by the group is a valid only if you are guarding from other users and not from root.

check /dev/dm (device mapper) .. that provides encryption .. earlier it used be called loop - device ( i think).

the process is entrely transparent after you set it up. you will be able to access it and no one else .. including root.
