#                  address are to include authentication fields,

#                  range  of  this number is that of an unsigned
#                  32 bit integer.  By  default,  an  encryption

#                  field is not included.
#         version  Specifies the version number to be  used  for
#                  outgoing  NTP  packets.  Versions 1, 2, and 3
#                  are the choices; version 3 is the default.

Sample ntp.conf file for an NTP primary stratum 1 server:

server 127.127.5.0
fudge 127.127.5.0 stratum 1

Sample ntp.conf file for an NTP server in peer mode:

peer ntppeerserver

Sample ntp.conf file for an NTP server in server mode: (Note: its recommended to have a minimum of 3 server entries, even more preferable is 5)

We can always fall back to the local clock:

server 127.127.1.0
fudge 127.127.1.0 stratum 9

Once you have created your ntp.conf file, save it and start the

xntpd daemon.

# /usr/lib/inet/xntpd &

you can specify different options for the daemon to run as:

     -a             Run in "authenticate" mode

     -b             Listen for broadcast NTP and sync to this  if
                    available

     -c   ----->    Specify an alternate configuration file

     -d    ----->   Specify debugging mode. This flag  may  occur
