NTPD.CONF(5)		     BSD Reference Manual		  NTPD.CONF(5)

NAME
     ntpd.conf - Network Time Protocol daemon configuration file

DESCRIPTION
     This manual page describes the format of the ntpd(8) configuration file.
     It has the following format:

     Empty lines and lines beginning with the '#' character are ignored.

     Keywords may be specified multiple times within the configuration file.
     They are as follows:

     listen on address
	     Specify a local IP address or a hostname the ntpd(8) daemon
	     should listen on. If it appears multiple times, ntpd(8) will
	     listen on each given address. If the exact string '*' is given as
	     an address, ntpd(8) will listen on all local addresses. Other-
	     wise, address can be followed by an asterisk ('*') and a UDP port
	     number to listen on instead of the default 123. ntpd(8) does not
	     listen on any address by default. For example:

		   listen on *
		   listen on 127.0.0.1
		   listen on ::1

     server address
	     Specify the IP address or the hostname of an NTP server to syn-
	     chronize to. If it appears multiple times, ntpd(8) will try to
	     synchronize to all of the servers specified. If a hostname
	     resolves to multiple IPv4 and/or IPv6 addresses, ntpd(8) uses the
	     first address. If it does not get a reply, ntpd(8) retries with
	     the next address and continues to do so until a working address
	     is found. For example:

		   server 10.0.0.2
		   server ntp.example.org
		   server ::1*12345

	     To provide redundancy, it is good practice to configure multiple
	     servers. In general, best accuracy is obtained by using servers
	     that have a low network latency.

     servers address
	     As with server, specify the IP address or hostname of an NTP
	     server to synchronize to. If it appears multiple times, ntpd(8)
	     will try to synchronize to all of the servers specified. Should
	     the hostname resolve to multiple IP addresses, ntpd(8) will try
	     to synchronize to all of them. For example:

		   servers pool.ntp.org

     keyword and the ability to specify a port first appeared in MirOS #10.
