Hello list
After samba4 installation cant install cifs-utils.
Is there an other way of mount an externall network drive without using
I try mount -t cifs // /mnt/backup/
But I get  "is not a valid block device" error

I have centos-release-6-4.el6.centos.10.x86_64

This ext drive is also linked to a fedora server without problem.

Thank you in advance.
