Login as root to the server and:
1) Edit " /etc/rc.config.d/netdaemons " file on the servers as follows : export NTPDATE_SERVER=
export XNTPD=1
export XNTPD_ARGS=

2)Edit " /etc/ntp.conf " file in the server with the below entries at the end of the file :

server
3) To Maually start xntpd daemon : # /sbin/init.d/xntpd start
ON the other server :

1)Edit " /etc/rc.config.d/netdaemons " file on the clients side as follows :
export NTPDATE_SERVER=
export XNTPD=1
export XNTPD_ARGS=
2)Edit " /etc/ntp.conf " file on the other server and add below entries at the end of the file:
server
3)#/sbin/init.d/xntpd start

In case the time synchronisation doesn't start it will definately start at the reboot of respective servers. 95 % it will start w/o reboot.

***Also note the following Two Points:-

1. We put following lines in ntp.conf for a time server that uses its own internal clock.

server 127.127.1.1
fudge 127.127.1.1 stratum=10

The IP address (127.127.1.1) is psuedo IP address that identifies that local system as a time source.

2. In case of client following entries are right

server pluto (
driftfile /etc/ntp.drift

Hello chindi,
You use one of server as NTP server and remaining are clients. but you need to check the NTP servers timings periodically.
use NTP servers IP addr in clients for update timings
