NTP Service

[Patricia Tang]

Hi All,

I have setup the ntp service recently and everything work fine.

I'm using command " ps -ef |grep ntpd" and notice that the ntpd daemon is stop every 15 minute. I have to restart it again and again

Anyone know what's go wrong?

Thanks in Advance

Regards,
Pat

Hi Patricia:

If your server's clock and its reference source differ by 1000 seconds or more, then the xntpd daemon will shut down as you describe. If this is the case, adjust your server to be nearly correct and restart the 'xntpd' daemon. You can do this at bootup with 'ntpdate' or with the '-a [-]sss[.fff]' option of 'date' on 11.x

hi,

This problem usually occurs if the NTP server's reference clock and the other system's
clock is way out of sync. Look at the
/var/adm/syslog/syslog.log file for the
ntp error messages. It will confirm this.

If this the case, then check the difference
between the problem server's date/time and
the ntp server's date/time. Change your
server's time accordingly and restart the
ntp daemon.

HI
Use #ntpq -p command to check the difference in your system clock and the source, and as mentioned by others, if they differ by 1000 seconds or more, then the xntpd daemon will shut down.
In this case, adjust your server to be nearly correct and restart the 'xntpd' daemon.
You can do this with 'ntpdate' command.

Adding #/usr/sbin/ntpdate -bv ${NTPDATESERVER} in the /sbin/init.d/xntpd file, before the xntpd daemon is started will help. So you can just stop and restart the xntpd.
#/sbin/init.d/xntpd stop
#/sbin/init.d/xntpd start

Thanks.
Prashant.
