Hi everyone...
 
I'll confige ntp server into isolated network.
There is two SUN system. A system is ntp_a, B system is ntp_b.
 
ntp_a will act ntp_b's NTP server, and ntp_b will act ntp_a's NTP server.
is it possible?
 
That configuration is...
 
  ※ ntp_a's /etc/inet/ntp.conf
       # @(#)ntp.server 1.4 97/05/05 SMI
       #
       # /etc/inet/ntp.server
       #
       # An example file that could be copied over to /etc/inet/ntp.conf and
       # edited; it provides a configuration template for a server that
       # listens to an external hardware clock, synchronizes the local clock,
       # and announces itself on the NTP multicast net.
       #
 
       # This is the external clock device. The following devices are
       # recognized by xntpd 3.4y:

       peer ntp_b prefer

  ※ ntp_b's /etc/inet/ntp.conf(another line is same with ntp_a)
       .
       .

       fudge 127.127.1.0 stratum 3
