Can't see/mount SMB shares through terminal

Peter Pfand · 01-03-2017, 05:02 AM

Dear Linux Users,
I would like to mount a SAMBA share on my computer, where I'm running Debian 8 (Jessie). The SMB share is located at the server of my institute and works as a domain controller (it's a SAMBA 4). All machines are located inside the private network of the institute.

I can see and mount the shares from a OSX 10.9.5 with:

Code:

smbutil view //<user_name>@<server_domain_name>/share

and:

Code:

mount_smbfs //<user_name>@<server_domain_name>/share ~/my_share

From my computer, I can access the share via nautilus (GNOME nautilus 3.14.1), through the "Connect to Server" option at the sidebar, with:

- smb://<server_domain_name>/share as Server Address
- <user_name>@<domain> as the username
- <domain>.es as the domain

However, it gives me the following error when using the command-line:

Code:

sudo mount.cifs //<server_domain_name>/share ~/my_share -o user=<user_name>@<domain>,workgroup=<domain>.es
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

I have tried removing the @<domain> part from the user, adding a $ at the end of the server address (//<server_domain_name>/share$), but everything has been unsuccesful.

When I try to connect to the server with smbclient, it gives me another error:

Code:

smbclient  //<server_domain_name>/share --user=<user_name>@<domain> --workgroup=<domain>.es
Enter<user_name>@<domain>.es's password: 
session setup failed: NT_STATUS_LOGON_FAILURE

And I get the same error with:

Code:

 smbclient -L //<server_domain_name>/share -U <domain>/<user_name> -W <domain>.es

It seems to be a Linux-related issue, since it works for OSX but not for Debian (I also tried up in Ubuntu and it did not work). Have I overlooked anything? I am unable to find a solution to this issue and I have been struggling with this more than two weeks...

I would appreciate some hints/comments about this, since I am aware I am not the only one person experiencing this, and after trying multiple apparent solutions from many forums, I still haven't found the right one.

Thanks in advance

If it works using nautilus then it should work on the command line... However, you are using the wrong syntax for user. It is either

user=username or user=workgroup/username

Try using:

Code:

sudo mount -t cifs //server_name/share ~/my_share -o user=username,domain=<domain>.es

See man pages for mount.cifs for more information.

I get the same error in that case. According to the man pages, it seems to be a permission-related issue. However, if I can access, as you say, via nautilus, I should have access through smbclient or mount.

I am a bit surprised by your error. I use workgroup= in the options instead of domain=, and it works.

Note that the command first asks for the sudo password, then for the share password.

sudo mount -t cifs //server_name/share ~/my_share -o user=username,workgroup=<domain>

You might want to do a sudo ls before issuing the command, enter sudo password, the you can be sure the password is for the user as specified in the command.

Post the output of:

Code:

grep '^\s*hosts' /etc/samba/smb.conf

Put both the loopback IP and the LAN IP into that 'hosts' line. Then restart samba.

Also, check your samba log file. If still does not work, check your firewall rules.

I get the same error again.

That's weird, I get no output with that grep, but the /etc/samba/smb.conf file exists.

Is there a password for your share? You could try to specify the password on the command line. Otherwise try the guest option.

Can you post the server output of:

Code:

pdbedit -L
testparm

Then from the client:
[code]
smbclient -L <server-IP> -U <username>

The server is on a FreeBSD system under oneFS, not Debian/Ubuntu, and we do not know how to (cannot) run such command on it. Any hint is appreciated.

It is for OSX and it works, I want it to work (with other commands) on Linux.

Have you checked if ntlmv2 options help? (In my /etc/fstab it is sec=ntlmv2.)
At work, I do a login based on a file in /root. That file has to have the right permissions, though, and there was a change in that before I could use something like

Code:

user=<domain>\<user>
password=<password>

(There's a backslash in between, just as on Windows. Might try that instead of a (forward)slash in some of your commands, too.)
and now I have to use something like

Code:

user=<user>
domain=<domain>
password=<password>

Also, there can not be any excess spaces in that file.

This tread really helped me! Thanks for posting guys.
