Hi Dhinesh,

Check the ntp service
#ps -ef |grep -i xntpd

check the synchronization of ntp with server

#ntpq -p

and are you able to ping the 124.41.84.72 server?

and check the system log file for regular NTP daemon messages..

[DHINESHBABU]

what my question is, i add external ntp server and, local clock.is it recommended to configure like this..

[Basheer_2]

Yes,
we always had an external source or windows machine as our primary ntp server.

you can also configure one of your unix box as the ntp server and all others as the clients

this is my ntp.conf (unix)
driftfile /etc/ntp.drift
broadcast 10.200.207.255 version 3
broadcastdelay 86400
server 127.127.1.1
fudge 127.127.1.1 stratum 10

Hi Dinesh,

Configuration are correct? are you facing any issue.

Please check in server
/var/adm/syslog/syslog.log file for any error.

Also check in client

#ntpq -p

and check for offest column whether it is synching with source server.

if your facing issue post the output of ntpq from client and syslog message from server.

Sync lost, synced .. message in syslog in every min.... in server and all clients

> sync lost...

What does the command:

ntpq -p 124.41.84.72

If it fails, you cannot contact the NTP server. You need to determine if the NTP server is working, is not blocked by network routers and will accept a sync request. Until nptq works, you won't be able to sync to that server.
