I've some issues with a windows share on Ubuntu 14.04 LTS.

  1. Installed cifsutils`:

    sudo apt-get install cifs-utils
  2. Created mountpoint

    sudo mkdir /mnt/temp
  3. Trying to mount a shared folder

    sudo mount -t cifs //fileserver/share /mnt/temp -o username=user,password=xxx

My problem is that the console hangs forever. I've waiting several minutes. If I enter wrong user/password it tells me Permission denied.


Response from Ubuntu Host computer:

nmap -p -v 445 fileserver -P0

host seems down / Filesharing seems to work though!

Ubuntu client computer (Inside vmware):

nmap -p -v 445 fileserver -P0

Host seems down / Filesharing doesn't work!

Maybe a lead: To autorize the fileshare I have to login on the domain.

Any suggestions?

  • Does dmesg | tail show anything interesting at that point? – Jos Nov 12 '15 at 14:05
  • CIFS VFS: cifs_mount failed w/return code = -112 – Fam Wired Nov 12 '15 at 14:50
  • I'm not sure about this, because I have to ctrl-break the action to be able to continue. – Fam Wired Nov 12 '15 at 14:51
  • Please edit your question, if you want to add information. Especially file or program output listings (with the help of the {} button in the editor toolbar) are much more readable there and overall it's best to have everything relevant in one place. Also, comments may be deleted for various reasons. – David Foerster Nov 13 '15 at 7:35

Finally I got it to work.

I used the ip-address ( instead of fileserver.

When ping:ing the fileserver name on the client I got ping response from another ip/computer ( than I got from the host computer ( !

Don't know why the dns name was linked to wrong ip on the client computer?

  • I believe the right way of going is using the IP address indeed. I will not go to the effort right now to prove it, but I remember reading that the cifs mount utility cannot handle the //fileserver notation. – Levente Feb 15 at 15:21

This is firewall issue for me . Install nmap on your ubuntu box with apt-get install nmap and run nmap -p 445 fileserver to see if the samba port is blocked by firewall or not.

Other way is to put -v sudo mount -v -t cifs //fileserver/share /mnt/temp -o username=user,password=xxx to see the verbose message from the mounting.

Hope it helps

  • Thanks. I got nmap response: Host seems down. I'm running this ubuntu inside another ubuntu host (vmware) – Fam Wired Nov 12 '15 at 14:37
  • I think you have right about the firewall. Do you know how to open the port? – Fam Wired Nov 12 '15 at 14:38
  • So, run nmap -p 445 fileserver -P0. 100% this is firewall issue! – Nikolay Nikolov Nov 12 '15 at 14:39
  • If the machine is windows , go to windows firewall settings. If it is ubuntu , maybe you should stop apparmor – Nikolay Nikolov Nov 12 '15 at 14:40
  • It works OK on the ubuntu host computer. It's the ubuntu inside the ubuntu that failes. – Fam Wired Nov 12 '15 at 14:53

Another possibility:

If you are using a standard VMWare Network-Configuration for that Virtual machine and following the documentation at http://pubs.vmware.com/workstation-10/index.jsp?topic=%2Fcom.vmware.ws.using.doc%2FGUID-4B9B4A82-D0F7-4939-BD7B-B6BF92FF7350.html

In a typical configuration, the New Virtual Machine wizard sets up NAT for the virtual machine. You must select the custom configuration option to configure bridged networking or host-only networking. The wizard connects the virtual machine to the appropriate virtual network.

Check out the VM's Network-Configuration and switch to bridged networking so that the VM has access to the same network-resources as your host machine.

Hope it helps.

NOTE: It was intended to be a comment, but I cannot do that yet :)

  • Thanks, the net on the virtual machine is bridge configured as you pointed out. It also got a ip-address in the same subnet as the fileserver. :) – Fam Wired Nov 16 '15 at 9:04
  • Your solution was going to be my next answer :-D Glad you sorted this out. – Eduardo López Nov 16 '15 at 9:39
