Cannot share or access local shared directory.

Postby opgog on Tue Apr 30, 2013 10:32 am

Hi there. Any help would be greatly appreciated.
First my setup: 64 bit Mint 14 Cinnamon.

My issue: I have one machine (Mint) with a directory I am trying to share. Its located at, /dev/sdc1 with the path, /media/toor/MTMData of which I have made sure I am the owner. I have created a user called "user1" and created an smb password for that user on the machine that hosts the shared directory.

I can see the machine hosting the share (cubit) on the network and its share label of MTMData. When I enter the user name and password the dialogue box disappears then reappears as if I have not entered any of the credentials. There is no authentication error reported that I can see and no entry to the shared directory.

The machine I am trying to access the share on is a Ubuntu 12.04 machine. The user name associated with it is user1.


Below is the output of testparm -s

Code: Select all
toor@cubit ~ $ testparm -s

Re: Cannot share or access local shared directory.

1st: A suggestion. If you really only want tour and user1 to gain access then remove the share you created in Nemo.

Those shares cannot specify valid users - only Classic samba shares ( in smb.conf ) can do that.

2nd: Everything looks perfect so the issue may be Linux permissions. Can you post the output of this command please:
Code: Select all
ls -al /media/toor
Please add a [SOLVED] at the end of your original subject header if your question has been answered and solved.

Additional information. Here is the output of /etc/samba/smb.conf


Code: Select all
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
#

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = workgroup

#### Networking ####

# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.

Re: Cannot share or access local shared directory.

Postby altair4 on Tue Apr 30, 2013 10:55 am

Never mind I think I know the problem. /media/toor will allow only toor to gain access because of the permissions on that folder.

Edit smb.conf directly and change this:
[MTMData]
path = /media/toor/MTMData
writeable = yes
; browseable = yes
valid users = toor, user1

To this:
[MTMData]
path = /media/toor/MTMData
writeable = yes
; browseable = yes
valid users = toor, user1
force user = toor

Then restart samba:
Code: Select all
sudo service smbd restart


That may look a little strange but the "valid users" line restricts access to those users but once they have provided the correct credentials they will be converted to "toor" and "toor is the only on who can gain access to what's within /media/toor.

And don't forget to remove the share created in Nemo.

Thanks for the quick reply. Here is the out put of ls -al /media/toor

Code: Select all
toor@cubit ~ $ ls -al /media/toor
total 20
drwxr-x---+  5 root root 4096 Apr 29 13:06 .
drwxr-xr-x   3 root root 4096 Apr 29 11:21 ..
drwxrwxrwx  12 toor root 4096 Apr 17 11:57 MTMData
drwxrwxrwx  12 toor root 4096 Apr 17 11:57 MTMData2
drwx------   3 toor toor 4096 Dec 31  1969 transit


I modded the file you requested and added force user = toor

Question: I created the share using the gui tool ( right click and choosing "Sharing Options" then "Share this folder" and "Allow others..." ). Should I remove those options then? Is that what you mean by removing the share in Nemo? Sorry I'm new to Nemo in general and Mint for that matter.

Yes basically undo everything you did to create the share that you made in Nemo.

There's 2 ways to create a samba share - one is through smb.conf itself:
[MTMData]
path = /media/toor/MTMData
writeable = yes
; browseable = yes
valid users = toor, user1

Another way is to create the share in nemo:
[MTMData]
path=/media/toor/MTMData
comment=
usershare_acl=Everyone:F,
guest_ok=n


You have 2 share definitions for the same folder and if you notice they are defined differently. One allows only toor and user1 to gain access while the other allows anyone with credentials to gain access. That's why it's not a good idea to use both methods at the same time on the same folder.
