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:
       #
       # XType Device    Name           Description

  ※ ntp_b's /etc/inet/ntp.conf(another line is same with ntp_a)
       .
       .
       server 127.127.1.0
       fudge 127.127.1.0 stratum 3
