Hi All,
I am running Cent OS 4.1 (same as Red Hat Enterprise
Linux 4.1, only cheaper).
How do I change ntpd's time server? I have altered,
/etc/ntp.conf and /etc/ntp/ntpservers to use time.nist.gov.
I stopped and restarted ntpd several times.
What am I doing wrong?
Looks like you are using pool.ntp.org. Search in /etc to find either
194.88.5.36 or pool.ntp.org. A way to search is using the command:
grep -r pool.ntp.org /etc
Hi Johan and Danny,
Thank you for the input. I went searching around for an
alternate ntp.conf file and did not find one. So, I renamed
/etc/ntp.conf and restart ntpd. Oh did it whine!
So I opened /etc/rc.d/init.d/ntpd and looked. Hmmm.
I echoed out $ntpconf from the readconf subroutine. Said
it was /etc/ntp.conf. Frustrated, I looked at /etc/ntp.conf
a few hundred more times. Then it occured to me to go back
/etc/rc.d/init.d/ntpd and check out the start routine.
Bingo!
if [ -s "$ntpstep" -o -n "$dostep" ]; then
# Synchronize with servers if step-tickers exists
# or the -x option is used
echo -n $"$prog: Synchronizing with time server: "
/usr/sbin/ntpdate $dropstr -s -b -p 8 \
$tickers 2>/dev/null >/dev/null
Okay, so tickers is hard coded as ntpstep=/etc/ntp/step-tickers.
I opened /etc/ntp/step-tickers and modified it to the following:
# 0.pool.ntp.org
# 1.pool.ntp.org
# 2.pool.ntp.org
time.nist.gov
127.127.1.0
Problem solved! You guys put me on the right track
to find the error. :-)
Many thanks,
--Tony
