| Summary : Network Time Protocol daemon (version 4)
|
Description :
The Network Time Protocol (NTP) is used to synchronize the time of a
computer client or server to another server or reference time source,
such as a radio, satellite receiver, or modem. It provides client
accuracies typically within a millisecond on LANs and up to a few tens
of milliseconds on WANs relative to a primary server synchronized to
Coordinated Universal Time (UTC) via a Global Positioning Service (GPS)
receiver, for example. Typical NTP configurations utilize multiple
redundant servers and diverse network paths, to achieve high accuracy
and reliability. Some configurations include cryptographic
authentication to prevent accidental or malicious protocol attacks.
Ntpd is an operating system daemon that sets and maintains the system
time-of-day synchronized with Internet standard time servers. Ntpd is a
complete implementation of the Network Time Protocol (NTP) version 4,
but also retains compatibility with version 3, as defined by RFC-1305,
and version 1 and 2, as defined by RFC-1059 and RFC-1119, respectively.
Ntpd does most computations in 64-bit floating point arithmetic and
does relatively clumsy 64-bit fixed point operations only when
necessary to preserve the ultimate precision, about 232 picoseconds.
While the ultimate precision is not achievable with the ordinary
workstations and networks of today, it may be required with future
nanosecond CPU clocks and gigabit LANs.
The daemon can operate in any of several modes, including symmetrical
active/passive, client/server broadcast/multicast, and manycast. A
broadcast/multicast or manycast client can discover remote servers,
compute server-client propagation delay correction factors, and
configure itself automatically. This makes it possible to deploy a
fleet of workstations without specifying configuration details specific
to the local environment.
Ordinarily, ntpd reads the ntp.conf configuration file at start-up time
to determine the synchronization sources and operating modes. It is
also possible to specify a working, although limited, configuration
entirely on the command line, obviating the need for a configuration
file. This may be particularly appropriate when the local host is to be
configured as a broadcast/multicast client or manycast client, with all
peers being determined by listening to broadcasts at run time.
Various internal ntpd variables can be displayed and configuration
options altered while the daemon is running using the ntpq and ntpdc
utility programs.
This build includes openssl support, and non-root patch from Timo
Felbinger. It requires linuxcaps.
The default configuration file /etc/ntp.conf uses pool.ntp.org servers
