NAME    [Toc]    [Back]

     ntpd - Network Time Protocol daemon

SYNOPSIS    [Toc]    [Back]

     ntpd [-d] [-f file]

DESCRIPTION    [Toc]    [Back]

     The ntpd daemon synchronizes the local clock to one or  more
remote NTP
     servers,  and  can  also act as an NTP server itself, redistributing the local
 time.  It implements the Simple  Network  Time  Protocol
version 4, as
     described in RFC 2030, and the Network Time Protocol version
3, as described
 in RFC 1305.

     ntpd is usually started at boot time, and can be enabled  by
setting the
     following in /etc/rc.conf.local:

           ntpd_flags=""

     See  rc(8)  and  rc.conf(8) for more information on the boot
process and enabling
 daemons.

     When ntpd starts up, it reads settings from a  configuration
file, typically
 ntpd.conf(5).

     The options are as follows:

     -d           Do not daemonize.  If this option is specified,
ntpd will run
                 in the foreground and log to stderr.

     -f file     Use file as the configuration file,  instead  of
the default
                 /etc/ntpd.conf.
