Unable to share folder on disk using Samba -Rights problem?-

[Tassadar]

Hi All,

I've a folder on my user folder that is shared using samba (shared with everyone), and works ok.

I've a secondary 2TB disk formatted with ext4, and a folder on it that I want to share. My problem is that as soon as I share it with Samba (shared with everyone) it un-shares itself automatically. I suspect that it's a problem is caused by the rights on this secondary disk.

I've use chown to take ownership on the disk:

sudo chown -R elhtpc /media/elhtpc/STORE

And I've also try chmod:

sudo chmod -R 777 /media/elhtpc/STORE

Problem persists.

How can I share a folder content on this disk?

Many thanks in advance

It would liklely be helpful and aid in troubleshooting if you would post your samba.conf here for review.
A streamlined version of your samba.conf can be captured to a file by executing:

bweinel@beck:~$ testparm > smb_conf.txt

It will also have the side benefit of giving your samba.conf file a sanity check at the same time.

Many thanks for the help, bweinel,

I've format disk again with gparted (ext4), so I can't write on disk (as usual), so I made:

chmod -R 777 /media/elhtpc/ALMACEN

(The actual name is ALMACEN, not STORE). Now I had access from the local machine to write and create folders.

I try to share a folder (right click, properties, share tab, share with samba, allow guests, everyone: full control, elhtpc:full control), and on Rights tab I set "Ohers: Can view and modify content" and check "Apply to subfolders and its contents".

In this moment the folder get the "shared" icon but I can't access to it from Windows machine. Another important thing is that the values I set on share tab seems to dissapear when I press "accept".

I've try to force all of my samba clients to look like "elhtpc" for the shares. I edit /etc/samba/smb.conf and add "force user = elhtpc" under the workgroup line.

Now I can access to the new shared folder but I have only read rights, not write. If I enter on share tab in folder properties, I set "allow guests, everyone: full control", but when I accept and enter again is changed to "read only".

I've try:

sudo chown -R elhtpc /media/elhtpc/ALMACEN

But problem persist.


I copy the result of testparm -s

¿How to get write access?

Many thanks in advance

I've just format the disk using ext3 instead of ext4 and now I can read/write in the disk from the Windows machine.

Am I missing important differentes if I "downgrade" from ext4 to ext3? The disk is going to be used mainly to manage downloads (transmission, jdownloader...) and storing files, films and tv series mainly.

Even with this, I would like to use ext4 if is possible in any way.

Many thanks in advance.

An ext4 file system should work fine with samba...

Your permissions and owners look ok. I beleive you just need to specify the shared directory in your samba.conf file.

Add this to the bottom of your samba.conf file:

[ALMACEN]
comment = shared directory
path = /media/elhtpc/ALMACEN
read only = No
create mask = 0766
directory mask = 0766
guest ok = Yes

Your create and directory masks can be adjusted depending upon what access you wish to give guest users.
