can you post the output of ntpq -p?

Re: system time

OFC_EDM — Wed, 30 Apr 2008 08:40:36 GMT

Did you stop the ntp (xntpd) daemon before running ntpdate?

Hi Sajjad

Did you enable NTP daemon in /etc/rc.config.d/netdaemons?

what is your ntp.conf file content?

Hi Sajjad Sahir,

if want to sync time each other you can use this command to sync time each other
/usr/sbin/ntpdate -b (ip of another server)

Hi again Sajjad

I understand what u configured is ok from your side. but sometimes the configuration may cause the problem.

Re: system time

Jeeshan — Wed, 30 Apr 2008 09:16:56 GMT

without ntp how could you synchronize your date in your network?

>>data2# ntpdate data1
30 Apr 15:26:35 ntpdate[2532]: the NTP socket is in use, exiting

this command will only applicable when there is a ntp server and synchonize its time to other server.

are you confused abt the time server or UTC time?

UTC is different thing. its aonly synchronize your server with UTC time.

Coooool Sajjad

If you manually changed the NTP server then your ntp daemon has been terminated.

Check that your xntpd daemon is running in both server.

#ps -ef|grep xntpd (check both servers)

then try the command

# ntpq -p

Sajjad Sahir — Wed, 30 Apr 2008 10:21:06 GMT

Hi:

The 'xntpd' daemon will NOT synchronize your server's time if it differs from that of a source by more than about 900 seconds. This prevents insane corrections.

You must set your server's time to be very close to the correct time first.

You can use 'date' to perform the adjustment. If you are setting time backwards, you should stop critical processes like databases first, You should also stop and restart the 'cron' daemon under these circumstances. Moving your server time forward is rarely a problem to time-sensitive processes.

Regards!
