Re: How can I set the NTP for my HP-UX 11i server

Hi,
I assume yuo are going to use an external NTP server (from internet) as time source.

Start SAM.
Select "Time".
Select "NTP Network time sources".
Select "Add remote server or peer" from action menu.
Type the name or IP adress for the NTP server.
Select "Relationship",Server and Preferred server.
Done

Make sure you can connect the the time servers listed in /etc/ntp.conf

What does the output of /usr/sbin/ntpq -p show?

You might check the NTP section of /etc/rc.config.d/netdaemons. Be sure you have NXTPD=1 or the init script won'tstart the deamon.

NTP Time server
===========
# cd /etc/
# /sbin/init.d/xntp stop
# vi ntp.conf
server 127.127.1.1 minpoll 3 maxpoll 4 prefer
fudge 127.127.1.1 stratum 10
broadcast ip

# /sbin/init.d/xntp start

NTP Client
======
# cd /etc/rc.config.d
# /sbin/init.d/xntp stop
# vi netdaemons

export NTPDATE_SERVER=node name
export XNTPD=1

# ntpdate
# /sbin/init.d/xntp start

Wait for about 5-8 min, run the follwoing to check the status:
# ntpq -p
chk for output of "reftime" it should not be zero if the servers are in sync.

Re: How can I set the NTP for my HP-UX 11i server

Just a note about ntpq before you get started. Most corporate firewalls won't let NTP services pass through. The good news is that most modern firewalls have NTP built-in so if your network admins did a good job, the firewall itself may already be synced to some of the many atomic clocks on the internet and in turn can act as your internal time service.

To verify that you have working time servers, use the ntpq command as in:

ntpq -p server_name_or_IPaddr

If you get a timeout or no service found, then the server is not reachable or is not providing NTP service. Once you have an NTP source(s), then follow the instructions above. It's always good to have several sources for reliability.

As far as ntp sources go, if you are told to point to a microsoft server on your network, it needs the latest version of Dr. Mill's NT/2000/XP ntp program.

The built in Microsoft time source programs didn't meet standards and HP boxes couldn't talk to them.

Re: How can I set the NTP for my HP-UX 11i server


when I use :

#ntpq -p

it can display the server which I set in the "netdaemons" and there have a sign "*" before the IP address mean use for sync

Moreover,
I don't why when I use:

#ntpq -q IP_Adderess

it prompt out time out, no request??
