Are you getting an error message?
What OS are you using?
Are you able to "reach" the timeserver?

You can contact prakash from BTOI...! :slight_smile: He is very Brilliant

We are using suse-linux and we are not getting any error messages. we tried 1. adding ntp server in ntp.conf file and restarting xntpd
2. using ntpdate -u <ntpserver>
this also doesn't work .

In /var/log/ntp these are the following messages.

Are you able to run ntpdate in debug mode?
maybe a clue is given....
ntpdate -d -u <ntpserver>
or maybe try different ntp server, and see what happens

maybe (non suse and non redhat) this can help
HOWTO NTP - Gentoo Linux Wiki

I tried in debug mode no error but the server is not getting synced up with the NTP server. Any more suggestions.

7

Can you post the output of the debug ntp sync run?
Maybe there is some clue what is happening.
(cause no error usually means it works...)

go to /etc/ntp.conf
remove everything from the file except
server 1
server 2
server 3
save it
service ntpd restart
then ntpdc -p
wait for sometime.
it will going to sync .....
