NTP Daemon

The Network Time Protocol (NTP) Daemon (a.k.a. "ntpd") listens for and responds to
requests from NTP clients. It also sends NTP requests to each of the NTP Associations and
qualifies each one. It synchronizes with the best NTP association and makes that time avail-
able to the

See the

NTP - Config

(on page 43) topics for more information.

NTP Packet

The NTP packet, represented using big-endian 32-bit rows, appears as follows:

Autokey uses the optional Extension Fields 1 and 2, which are not described below.

Autokey and Symmetric Key Authentication both use the Key Identifier and Message Digest
fields.

Leap Indicator (LI)

The Leap Indicator (LI) is a two-bit binary number in the NTP packet header that provides
the following information:
