want to share Windows partition on Samba unable to change permissions

[jamesbon]

I have a windows partition which I Can easily access via nautilus gui.Without manually mounting the partition.When I click on the hard disk icon it automatically gets mounted at /media.

 sudo fdisk -l

Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors
Units = sectors of 1 * 512 = 512 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda2          206848   163839999    81816576    7  HPFS/NTFS/exFAT
/dev/sda3       163840000   368639999   102400000    7  HPFS/NTFS/exFAT

/dev/sda5       368642048   625139711   128248832    7  HPFS/NTFS/exFAT

Here is my /etc/fstab file

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
/host/ubuntu/disks/root.disk /               ext4    loop,errors=remount-ro 0       1
/host/ubuntu/disks/swap.disk none            swap    loop,sw         0       0
~

and following are entries of smb.conf

[hell]
   comment = Winows files
   read only = yes
   locking = no
   browseable = yes
   path = /media/New\ Volume
   guest ok = yes
   public = yes

The client machine tried to connect but it failed to mount the Windows partition from the server.
Upon digging a further I noticed the permissions of volume in /media for others and group are 00
The permissions I see are

deel@ubuntu:/media$ ls -l
total 16
drwx------ 1 deel deel 16384 2011-11-16 10:33 New Volume

So assuming that samba client process does not have read permissions to above I tried to change the permissions at server.

deel@ubuntu:/media$ sudo chmod 755 New\ Volume/

But now they did not changed

deel@ubuntu:/media$ ls -l  

total 16
drwx------ 1 deel deel 16384 2011-11-16 10:33 New Volume

If you notice in above even after changing permissions the permissions have not changed. What could be the reason and how can I share the windows partition on samba server to my network?

Just to be sure, did you install:
sudo apt-get install ntfs-3g

 sudo fdisk -l

yes

When you mount an ntfs partition from nautilus it mounts with you being the only one that can access it. That's by design. You can't do a chmod or chown on an ntfs partition since there are no linux permissions or ownership "bits" to set but there is an easy way out of this problem.

Change this:

[hell]
comment = Winows files
read only = yes
locking = no
browseable = yes
path = /media/New\ Volume
guest ok = yes
public = yes

To this

[hell]
comment = Winows files
read only = yes
locking = no
browseable = yes
path = /media/New\ Volume
guest ok = yes
force user = deel
public = yes

Then restart samba:

sudo service smbd restart

The remote "guest" will be converted to "deel" for that share and therefore will have access to the directory but still be controlled by the "read only = yes" restriction in the share definition.

Thanks for clearing this out.

This is a good suggestion.
