NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

Source releases and patches

The NTP project only produces source code releases of NTP. These releases may be installed using the standard Unix "make" command. Please contact your operating system vendor for binary packages or assistance with your package-management system. NTP users who wish to track the development version of NTP should see the development page, because NTP tarballs are produced infrequently. Most users should download from the table below.
