And upgrade them.

Some software distributors don’t ship modern software.  if you
are using a distribution packaged ntpd it’s likely old and
difficult to determine its lineage due to how it’s packaged.

If you’re using Redhat based systems consider using chrony 
instead, even the new beta fedora 24 uses 4.2.6 derived code
vs 4.2.8
