NTP Configuration.

[Amit Mehta]

I want to synchronize ntp on HP-UX B.11.00 9000/800 with a time server in the US. Could you please tell me what changes I would have to make in the ntp.conf file. I'd really
appreciate your assistance.

You simply need to add a line something like this to get the time from the US Naval Observatory:

server navobs1.wustl.edu version 3 prefer

navobs1.wustl.edu ip address is 128.252.19.1

I would then sync all the time on your network to this local timeserver.

Hi Amit,

To synchronize your server time to another server, just add a line in /etc/ntp.conf file,

server ip_add_of_time_server version 3 prefer

The details on adding version 3 prefer and other options are mentioned as comment in /etc/ntp.conf file.

Hope this helps.

Do I also have to specify a drift file and the
polling setting ?

And the line you mentioned is simply
server right ?

[John Payne_2]

You don't HAVE to specify the driftfile or polling interval. The polling will default for you, and not specifying a driftfile just means there will not be one.

The driftfile can be nice to have, though, if you ever want to see the last step that was taken. Be sure to actually create the file if you specify it. (I usually create the file with a '1' entered in it...)

Hi,

Before you configure it,
make sure the ntp daemon is shutoff (ps -ef |grep ntp
and kill the pid if it exists)
**
edit /etc/ntp.conf file
and see whether you have a
"server" entry at the end of the file (not commented!).
Change it (or correct it) to
server .domainname version 3 prefer

Edit /etc/rc.config.d/netdaemon and
export NTPDATE_SERVER=".domainname""
XNTP=1

to start it
/sbin/init.d/xntpd start
Wait for 5 minutes and
check it by ntpq -p
***

This is the setting i have on my system and it works fine.

HTH
