How do I check what version of 'cifs-utils' I have installed?

Question

I am trying to mount my Buffalo NAS:

/etc/fstab:

//192.168.2.20/Movies /mnt/Movies cifs rw,noexec,nosuid,password=Password1,username=buffalonas,nodev

When execute the following command, I am getting the error below:

crash@crash-M17x:/sbin$ sudo mount -a

mount: wrong fs type, bad option, bad superblock on //192.168.2.20/Movies,
       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

I have read via other forums that I need to update or install cifs-utils because I currently do not have /sbin/mount.cifs file, only mount.files I have are mount.ntfs

But when I execute:

crash@crash-M17x:/sbin$ sudo apt-get install cifs-utils

Reading package lists... Done 
Building dependency tree 
Reading state information... Done 
cifs-utils is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

So how do I know if I have the latest cifs-utils? and if I already do have the latest, how do I install the mount.cifs files?

Answer 1

You can see the version and where it comes from with this command:

apt-cache policy cifs-utils

With this command you can see all the files that the package installs:

apt-file list cifs-utils

cifs-utils: /etc/request-key.d/cifs.idmap.conf
cifs-utils: /etc/request-key.d/cifs.spnego.conf
cifs-utils: /sbin/mount.cifs
cifs-utils: /usr/bin/cifscreds
cifs-utils: /usr/bin/getcifsacl
cifs-utils: /usr/bin/setcifsacl
cifs-utils: /usr/sbin/cifs.idmap
cifs-utils: /usr/sbin/cifs.upcall
cifs-utils: /usr/share/doc/cifs-utils/NEWS.Debian.gz
cifs-utils: /usr/share/doc/cifs-utils/README
cifs-utils: /usr/share/doc/cifs-utils/changelog.Debian.gz
cifs-utils: /usr/share/doc/cifs-utils/copyright
cifs-utils: /usr/share/man/man1/cifscreds.1.gz
cifs-utils: /usr/share/man/man1/getcifsacl.1.gz
cifs-utils: /usr/share/man/man1/setcifsacl.1.gz
cifs-utils: /usr/share/man/man8/cifs.idmap.8.gz
cifs-utils: /usr/share/man/man8/cifs.upcall.8.gz
cifs-utils: /usr/share/man/man8/mount.cifs.8.gz

As you can see it installs /sbin/mount.cifs.

And finally with this command you can check if all the md5sums are correct:

dlocate -md5check cifs-utils
