Unable to mount an anonymous CIFS share from Ubuntu 13.04

Asked by Antonio Gómez-Muriana

I'm trying to automount a network share when the system boots up or the user logins.
The network share is an external hard disk attached to a DSL home router.

I can mount it manually from Nautilus with the URL: smb://livebox/DiscosUSB/
However, I cannot mount with mount.cifs
I have tried this different sec parameters, with errors 95 and 56 on each case:

root@ubuntu:~# mount.cifs //livebox/DiscosUSB/ /mnt/zeta --verbose -o guest,sec=ntlm

mount.cifs kernel mount options: ip=192.168.2.1,unc=\\livebox\DiscosUSB,guest,sec=ntlm,user=,pass=********
mount error(95): Operation not supported
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

root@ubuntu:~# mount.cifs //livebox/DiscosUSB/ /mnt/zeta --verbose -o guest,sec=none

mount.cifs kernel mount options: ip=192.168.2.1,unc=\\livebox\DiscosUSB,guest,sec=none,user=,pass=********
mount error(56): Invalid request code
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

If I write a 7 into /proc/fs/cifs/cifsFYI, I can see the following on dmesg:

Hello,

I don't understand this answer. That is not the same issue. I'm cannot mount it neither with mount -t cifs
Moreover, the proposed solution, installing smbfs is not possible as is not available on Raring.

Regards,

Try installing smbclient. May help.

Antonio Gómez-Muriana (antoniogm) said : 		#6

I can access with smbclient. But I need to access with mount.cifs to be able to put in fstab.

You can put the mount command in /etc/rc.local above the 'exit 0' line and it will mount. This also gives the network time to come up as fstab is processed before the network is brought up and the line will fail.

Antonio Gómez-Muriana (antoniogm) said : 		#8

That won't help as this is not an fstab issue. The issue is with mount.cifs command.

As I said in my question, I can access to the SMB from Nautilus or even with smbclient.
But mount.cifs doesn't work, so I cannot put it on any script.

Why not use smbclient if it works...

Revision history for this message
Antonio Gómez-Muriana (antoniogm) said : 		#10

Do you mean to mount the share using smbclient into rc.local?
Which smbclient parameters should I use to mount a smb share into a folder?

Did you try with sec=lanman ?
