Need help from Redhat users!

[novkhan]

Goodday.

OS: Redhat 9

Harddisk : FAT
Need help becoz i couldnt really get users to write data into my FAT formatted harddisk.
i have aready mounted hdb5 (which is the FAT harddisk) to a folder call "windows"

Only Root have RWX permission on FAT windows.
[root@localhost mnt]# ls -l windows
total 4
drwxr-xr-x 2 root root 4096 Jun 8 00:58 Recycled

I want to allow user to have Write permission on the harddisk as well.
[root@localhost mnt]# chmod u=rwx windows

[root@localhost mnt]# ls -l windows
total 4
drwxr-xr-x 2 root root 4096 Jun 8 00:58 Recycled

But it doesnt work

I tried to change ownership to a user call novkhan but it doesnt work as well!

[root@localhost mnt]# chown novkhan windows
chown: changing ownership of `windows': Operation not permitted
[root@localhost mnt]# ls -l windows
total 4
drwxr-xr-x 2 root root 4096 Jun 8 00:58 Recycled

I hope to achieve WRX for all users on my FAT Harddisk.

drwxr-wxr-wxr

please help !
Thankyou!

novkhan,

I have never tried to do this before (to a fat), but doesn't it work the same as any other directory or file:

If the directory was named "sandy"

chmod 777 sandy

**the result should be: drwxrwxrwx

chmod 755 sandy

**the result should be: drwxr-xr-x

chmod 700 sandy

**the result should be: drwx------

chmod 644 sandy

**the result shoud be: drw--r--r--

and: chmod 000 sandy

**the result should be: d---------

[root@localhost mnt]# chmod 777 windows
chmod: changing permissions of `windows' (requested: 0777, actual: 0755): Operation not permitted

try "chown /mnt/windows root" first, and then the chmod command, i've seen this problem before with some things i've downloaded, but after the chown command it worked...

[root@localhost mnt]# chown /mnt/windows root
chown: `/mnt/windows': invalid user
[root@localhost mnt]# chown /mnt/windows novkhan

First off, why is the partition fat? Second, give each user a folder and then set permissions for each users

chmod 755 /mnt/windows/sandy
chmod 755 /mnt/windows/mike
etc...

I'm still curious as to why the partition is FAT

chmod won't cut it here. You have to either specify the option "user" when mounting the partition (or in fstab) or (better option) add a valid umask to the fstab file. "man mount" should do the trick.

Hey thanks, not having experimented with it before, is that because we are mounting a partition verses just a file or directory?

[cgkanchi]

Relyt,
Sort of. When you mount a device, Linux resets the permissions of the directory to whatever is specified in the fstab file for that file. If the fstab file is empty or says "defaults" in the options section, Linux will only allow root to read and write to and from that device.

cgkanchi,

Thanks, for the explanation.

Linux resets the permissions of the directory to whatever is specified in the fstab file for that file. If the fstab file is empty or says "defaults" in the options section, Linux will only allow root to read and write to and from that device.

You have to either specify the option "user" when mounting the partition (or in fstab) or (better option) add a valid umask to the fstab file. "man mount"

That makes sense and is hereby stored in the brain bank for later withdraw.
