Mounting NAS using FSTAB & .Credentials file - works on Linux Mint, not on Ubuntu

Hi all,

Just looking to see if there is something fundamental that differs between Linux Mint and Ubuntu.

On my Mint machine I use FSTAB and a .credentials file in /root to mount my NAS, called nas2.

I wanted to achieve the same on my Ubuntu 14.04 machine, so I copied the line into fstab:

//192.168.1.76/nas2 /mnt/nas2 cifs credentials=/root/.nas2cred,rw,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777

When I use sudo mount -a, I get this:

$ sudo mount -a
mount: wrong fs type, bad option, bad superblock on //192.168.1.76/nas2,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

$ sudo chmod 600 .nas2cred

I can browse the network using Nautilus and add bookmarks, but for certain programs I really need it permanently mounted in my /mnt directory.

I got it working on the Mint machine with the above entries more by luck than judgement, so by no means fully understand about users and permissions etc.. (ie: I may need a little hand-holding!)

Thanks, Scott.
