Not able to mount samba shares?

martinprowe · October 16, 2017, 11:52pm

Hi,

I have a samba disc share on my modem. I can mount this share from 42.2 & 42.3 but NOT Tumbleweed?

~# mount -t cifs //192.168.0.1/sda1 /smb
Password for root@//192.168.0.1/sda1:
~#

Works for 42.2 & 42.3.
However, this is what I get in Tumbleweed:

~# mount -t cifs //192.168.0.1/sda1 /smb
Password for root@//192.168.0.1/sda1:  
mount error(112): Host is down
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
~ #

Any suggestion? Insistently, the 42.x workstations are VMs on the Tumbleweed host.

Regards, Martin

Hi
I would try connecting via smbclient and add some debug. I’m guessing samba/ssl changes perhaps?


smbclient -d3 -L //192.168.0.1/
smbclient -d3 //192.168.0.1/<share listed from above>

Repeat on a working system and compare… on the Leap systems have you added any tweaks in /etc/samba/smb.conf?

Thanks for the suggestions, Malcolm. Results follow?

First, SuSE Leap 42.2 (mount -t cifs <etc> will work)

Conclusions: Identical results (I think?)

Now try a connection.
As I understand it, the smbclient provides an FTP type context rather than a drive mapping service(?)

Once again, using smbclient, I get similar results on Leap & Tumbleweed.

Does this offer any insights for you Malcolm, as to why mount -t cifs is not playing-ball on Tumbleweed?
One more small bit of evidence - Dolphin can see and map the smb share fine. But in the light of the above, I don’t think that this is all that surprising.

mount -t cifs -o vers=2.1 /blah /blah

Try dropping to 2.0 or 1.0 if it fails.

deano_ferrari · October 17, 2017, 10:28am

Yes, as Miuku mentioned try specifying the samba protocol explicitly.

From ‘man mount.cifs’…


vers=
SMB protocol version. Allowed values are: 

• 1.0 - The classic CIFS/SMBv1 protocol. This is the default.


• 2.0 - The SMBv2.002 protocol. This was initially introduced in Windows Vista Service Pack 1, and Windows Server 2008. Note that the initial release version of Windows Vista spoke a slightly different dialect (2.000) that is not supported.


• 2.1 - The SMBv2.1 protocol that was introduced in Microsoft Windows 7 and Windows Server 2008R2.


• 3.0 - The SMBv3.0 protocol that was introduced in Microsoft Windows 8 and Windows Server 2012.


Note too that while this option governs the protocol version used, not all features of each version are available.

martinprowe · October 17, 2017, 10:46am

WooHooo…

Thank you all VERY much. Yes, Vers=1.0 did the trick.

Ironically, I had tried that line already. I tried 3.0, 2.1 etc, BUT as 1.0 was the default I did not explicitly state it. Silly me!
So, In LEAP 42.x you can leave it off but in Tumbleweed I needed this in my /etc/fstab

//192.168.0.1/sda1 /smb cifs username=guest,password=""**,vers=1.0 **

Once again you have all come to my rescue.

Good to read of your success with this!

deano_ferrari · October 17, 2017, 8:02pm

Yes, it’s no longer the default since a few months back and now disabled (unless specified specifically). I assume this is now reflected in the mount,cifs man page for the TW version?

h2nek · February 24, 2018, 6:50pm

Thank you very much deano_ferrari](https://forums.opensuse.org/member.php/122-deano_ferrari) !!!

It works for me with :

//my.local.ip/share /myshare cifs _netdev,guest,vers=1.0 0 0

Encore merci mon ami
