I have Centos machine that want to mount files from NAS, but when passing guest user, it want password:

mount.cifs // /mnt/files -o guests,nocase

In another machine near this virtual machine which is centos, it mounted successfully.

Even added this /etc/fstab :

// /mnt/files cifs nocase,username=guests,password= 0 0

And saw the boot log:

localhost mount: mount error(112): Host is down

localhost mount: Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

localhost systemd: mnt-files.mount mount process exited, code=exited status=32

localhost systemd: Failed to mount /mnt/files.

What's the problem?
