zhu, I think you have a chinese character set enabled which means we can't really see what you're asking. the previous answers should hopefully point you to some useful resource though.

[zhu Longlin]

Thanks!It's a experience share.Sorry that I use Chinese.
In Hp-Ux ,we will meet some customer want to config NTP service using local or web NTP server,I will share these two ways:
suppose that we have two local servers:server1(172.22.22.1),server2(172.22.22.2),one web NTP server(192.12.19.20),this can get from web site:http://www.eecis.udel.edu/~mills/ntp/clock1b.html,you can select the one you like,the local time will be set correct according to your TIMEZONE
1.use local server as NTP server:
in NTP server:
a.vi /etc/rc.config.d/netdaemons
change export XNTPD0ï¼ 0-->export XNTPD0ï¼ 1;
bã vi /etc/ntp.conf
add three lines in the end:
server 172.22.22.1
fudge 127.127.1.1 stratum 10
driftfile /etc/ntp.drift
cã /etc/init.d/xntpd stop

dã /etc/init.d/xntpd start

Client:
aã vi /etc/rc.config.d/netdaemons
change export NTPDATE_SERVER=--->export NTPDATE_SERVER="172.22.22.1"
change export XNTPD0ï¼ 0-->export XNTPD0ï¼ 1;
bã vi /etc/ntp.conf
add three lines in the end:
server 172.22.22.1
fudge 172.22.22.1 stratum 10
driftfile /etc/ntp.drift
cã /etc/init.d/xntpd stop

dã /etc/init.d/xntpd start
noteï¼ the client ntp daemons must wait 6mins,or will appear the error info:â No Server suitable for synchronization foundâ

2.use public NTP server:
1ã vi /etc/rc.config.d/netdaemons
change export NTPDATE_SERVER=--->export NTPDATE_SERVER="192.12.19.20"
change export XNTPD0ï¼ 0--->export XNTPD=1ï¼

2ã vi /etc/ntp.conf
add three lines in the endï¼
server 192.12.19.20
fudge 192.12.19.20 stratum 0
driftfile /etc/ntp.drift

cã /etc/init.d/xntpd stop

dã /etc/i

[Sanjay Kumar Suri]

So it is your expereince. I have to add the following:

Client:
aã  vi /etc/rc.config.d/netdaemons
change export NTPDATE_SERVER=--->export NTPDATE_SERVER="172.22.22.1"
change export XNTPD0ï¼ 0-->export XNTPD0ï¼ 1;
bã  vi /etc/ntp.conf
add three lines in the end:
server 172.22.22.1
fudge 172.22.22.1 stratum 10
driftfile /etc/ntp.drift
cã  /etc/init.d/xntpd stop

In the above configuration for client following line in /etc/ntp.conf is not needed.
