NTP 서버 셋팅하기

 

NTP 서버 셋팅하기

-----------------------------------

SERVER 셋팅

cp /etc/inet/ntp.server /etc/inet/ntp.conf

vi /etc/inet/ntp.conf

server 127.127.XType.0 fudge 127.127.XType.0 stratum 0 라고 되어 있는 내용을 다음과 같이 수정 server 127.127.1.0 fudge 127.127.1.0 stratum 0

ls /var/ntp/ntp.drift 파일이 있는지 확인

없다면 파일생성 touch /var/ntp/ntp.drift

/etc/init.d/xntpd start

( 솔라리스 10일 경우 svcadm -v enable ntp)

# ps -ef | grep ntp ...

# snoop | grep -i

 

--------------------------------------

CLEINT 셋팅

cp /etc/inet/ntp.client /etc/inet/ntp.conf

vi /etc/inet/ntp.conf

multicastclient 1.1.1.1 (앞전에 설치했던 NTP 서버 IP)

date 0101012007

2007년 1월 1일 월요일 오전 01시 20분 00초

/etc/init.d/xntpd start

( 솔라리스 10일 경우 svcadm -v enable ntp)

 

# ps -ef | grep ntp

# date 서버와 동기되었는지 확인

 

NTP 셋팅 제거

-------------------------------------------

SERVER

/etc/init.d/xntd stop

( 솔라리스 10일 경우 svcadm disable ntp )

ps -ef | grep ntp

rm /etc/inet/ntp.conf

rm /var/ntp/ntp.drift

-------------------------------------------

CLIENT

/etc/init.d/xntd stop

( 솔라리스 10일 경우 svcadm disable ntp)

ps -ef | grep ntp => 멈췄는지 확인....

rm /etc/inet/ntp.

# /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

# -------------------------------------------------------

#  1    local     LCL            Undisciplined Local Clock

#  2    trak      GPS            TRAK 8820 GPS Receiver

#  3    pst       WWV            PSTI/Traconex WWV/WWVH Receiver

#  4    wwvb      WWVB           Spectracom WWVB Receiver

#  5    true      TRUE           TrueTime GPS/GOES Receivers

/

# 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.
