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 ‘*’ is given as an address,
              ntpd(8) will listen on all local addresses.   ntpd(8)  does  not
              listen on any address by default.  For example:

              listen on *
              listen on 127.0.0.1
              listen on ::1

              NOTE:  By  default,  OpenNTPd on Debian *does not listen* on any
              address.

       server address
              Specify the IP address or the  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.  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

              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
