1. mount error: could not resolve address for Diskstation: Unknown error
   

   Hi,

   I try to mount my NAS onto Ubuntu 12.04. This is my situation:

   Code:

   $ smbtree
   WORKGROUP
       \PX-EH                  PX-EH
           \PX-EHlp                 
           \PX-EHADMIN$             IPC Service (PX-EH)
           \PX-EHIPC$               IPC Service (PX-EH)
           \PX-EHGuest              
           \PX-EHdisk               LAN disk
       \DISKSTATION            
           \DISKSTATIONIPC$               IPC Service ()
           \DISKSTATIONhome               home
           \DISKSTATIONhomes              user home
           \DISKSTATIONNetBackup          System default shared folder
           \DISKSTATIONShare              DiskStation 212

   Then I try this

   Code:

   $ sudo smbmount //Diskstation/home samba
   mount error: could not resolve address for Diskstation: Unknown error

   I even tried Diskstation with capitals and with non-capitals, but no success.
   When I do

   Code:

   $ nmblookup -R -U <<IP-address>> diskstation
   querying diskstation on  <<IP-address>>
    <<IP-address>> diskstation<00>

   It seems there are some non-printable odd characters behind ‘diskstation’.

   With the PX-EH nas, I have the same problems, so it is not caused by the others side.

   I don’t want to type an IP-address. I want to use names, that’s what they’re for.

   How can I mount my NAS with its name?
   And if I need to add the name to some hosts file, why can I browse the samba drives with Nautilus without such a hosts file?

   Where are you attempting to mount //Diskstation/home to? The location samba seems incorrect.

   Code:

   $ nmblookup -R -U <<IP-address>> diskstation
   querying diskstation on  <<IP-address>>
    <<IP-address>> diskstation<00>

   It seems there are some non-printable odd characters behind ‘diskstation’.

   These are part of the NETBIOS protocol. They identify the type of node (i.e server or master browser or client).

   With the PX-EH nas, I have the same problems, so it is not caused by the others side.

   How can I mount my NAS with its name?
   And if I need to add the name to some hosts file, why can I browse the samba drives with Nautilus without such a hosts file?

   I’ll bet the mount command is incorrect. Where are you trying to mount //Diskstation/home to? What’s the mount point?

   Hi bab1,

   ‘samba’ is a directory in /mnt. So I try to be less ambiguous. Here is another attempt:

   Code:

   ~$ sudo smbmount //Diskstation/home /mnt/samba
   mount error: could not resolve address for Diskstation: Unknown error
   ~$ ls -l /mnt
   total 4
   drwxr-xr-x 2 root root 4096 Nov 12  2010 samba

   Does the samba directory have the correct permissions?

   The directory permissions are not a problem for mounting the share. You are having a problem resolving the name. What do you get with this command

   Code:

   smbclient -L diskstation

   The COMPUTER name is case insensitive so caps are not needed at the CLI on Ubuntu.

   This shows that the name is being resolved correctly. I’ll bet you need to use a more current mount command. The command smbmount is part of the deprecated smbfs package. The newer package CIFS-UTIL will work better. The basic command is something like

   Code:

   mount -t cifs //SERVER/share /path/to/mountpoint -o options
   
   or 
   
   mount.cifs //SERVER/share /path/to/mountpoint -o options

   See here and .here for info.

   Hi bab1,

   I forgot to mention that I already tried mount -t cifs, with the same result:

   Code:

   ~$ sudo mount -t cifs //diskstation/home /mnt/samba
   mount error: could not resolve address for diskstation: Unknown error

   If I do

   Code:

   sudo mount -t cifs //192.168.0.2/home /mnt/samba

   I am being asked for a password, so I can contact my NAS.

   I am getting a little frustrated. This isn’t the first time Ubuntu lets me down
   If nautilus can translate names to ip’s (and mount them), why can’t I do it on a CLI?! Which command should translate the names to the ip’s?

   Regards,

   ffonz

   The NETBIOS NAME DISKSTATION is being resolved by Samba. You can see that by the smbclient command. I’m sure that this will work too

   Code:

   nmblookup diskstation

   The mount command does have problems. What is the output of

9. Re: mount error: could not resolve address for Diskstation: Unknown error
   

   Hi bab1,

   OK, thanks. The nmblookup command works. This is something I can start with.

   The hosts file is

   Code:

   ~$ cat /etc/hosts
   127.0.0.1    localhost
   127.0.1.1    alfons-laptop
   
   # The following lines are desirable for IPv6 capable hosts
   ::1     localhost ip6-localhost ip6-loopback
   fe00::0 ip6-localnet
   ff00::0 ip6-mcastprefix
   ff02::1 ip6-allnodes
   ff02::2 ip6-allrouters
   ff02::3 ip6-allhosts

   I’m not so fond of adapting hosts files. As far as I know, then I have to manually adapt the hosts file on every machine in the network. Or are you thinking in a different direction?

   Regards,

   Alfons

    At this point it appears there is no DNS resolution. We do have NETBIOS resolution because nmblookup works. All Ubuntu hosts resolve hostnames by first looking in the hosts file. If therre is no mapping then DNS is tried. We can see if a hostname mapping in /etc/hosts works by mapping the host diskstation to the IP address in /etc/hosts like this

    Code:

    127.0.0.1    localhost
    127.0.1.1    alfons-laptop
    
    # Temp mapping of Diskstation to its IP address
    192.168.0.2  diskstation

    …If this works, it confirms that you do not have local DNS name services working.

    Try to mount the share via //diskstation/share We shall see what happens with the temp config in your /etc/hosts file. This is only a test right now.
