NTP sync

How do I get my NTP clients to sync with a new ntp server?

make sure the daemon is running. You can start it by running
/sbin/init.d/xntp start

. If you made a change to the configuration and the processes is up, you will need to stop, and restart it

Check out SAM. Also the file you are interested in is /et/ntp.conf. It should look something like this:

server nnn.nnnn.nnn.nnn
peer host1.ctxix.sod.eds.com version 3
peer host2.ctxix.sod.eds.com version 3
peer host3.ctxix.sod.eds.com version 3

Hi Robert,

In /etc/ntp.conf, place the entry

server your_ntp_server version 3 prefer
server secondary_ntp_server version 3

The second line is only if you have a secondary ntp server.

Then edit /etc/rc.config.d/netdaemons

export NTPDATE_SERVER=your_ntp_server
export XNTPD=1

Then run /sbin/init.d/xntpd start

This should bring up xntpd and will continue to sync with your_ntp_server

HI
On ntp clients add the NTP server address in /etc/ntp.conf file

##--
server minpoll 6 prefer
server minpoll 6
#
Restart ntp services on client.
Run ntpdate command on client first time to adjust the time before starting ntp daemon.
#ntpdate -v

Here is link to NTP configuration.

Hi Robert:

Just because no one has explictly stated it, I'm going to do so:

After you have editted '/etc/ntp.conf' to point to your new server(s), stop and then (re)start the 'ntpd' daemon as:

# /sbin/init.d/xntpd stop
# /sbin/init.d/xntpd start

Regards!

Robert

These are the 2 servers that we are syncing from. So far we haven't had any issues with these.

server ntp.ctr.columbia.edu prefer
server ntp.ctr.columbia.edu

Perform the following steps to start & stop NTPD.

1) /sbin/init.d/xntpd stop
2) /sbin/init.d/xntpd start

#ntpq -p
remote refid st t when poll reach delay offset disp
==============================================================================
*due.com gpclock01.net. 2 u 726 1024 377 1.30 -0.471 0.41

As everone says but if your time is too far from server's time then you need ntpdate.

ntpdate -d servername (this will test that ntpdate will run or not.)
