Solaris 8/9 NTP Configuration Process

 

 

NTP Server :10.87.0.9

NTP Client : 10.87.0.241

 

(1)   On Server :

[1] Edit ntp.conf

root@TESTMACHINE #cd /etc/inet

root@TESTMACHINE # ls

datemsk.ndpd             mipagent.conf.fa-sample  ntp.server

hosts                    mipagent.conf.ha-sample  protocols

inetd.conf               netmasks                 services

ipnodes                  networks                 slp.conf.example

ipsecinit.sample         ntp.client               sock2path

mipagent.conf-sample     ntp.conf

root@TESTMACHINE #vi ntp.conf

# @(#)ntp.server        1.5     99/09/21 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 3-5.93e:

#

# XType Device    RefID          Description

# 26    hpgps     GPS            Hewlett Packard 58503A GPS Receiver

# 27    arc       MSFa           Arcron MSF Receiver

#

# * All TrueTime receivers are now supported by one driver, type 5.

#   Types 15 and 25 will be retained only for a limited time and may

#   be reassigned in future.

#

# Some of the devices benefit from "fudge" factors.  See the xntpd

# documentation.

 

# Either a peer or server.  Replace "XType" with a value from the

# table above.
