Hi Mayer,
I have done the required changes. I have found one problem regarding condition
field in ntpq
When ever I have restarted ntpd on client and executed ntpq "as"
atcafs-n11s2:~# ntpq
ntpq> as
ind assid status conf reach auth condition last_event cnt
===========================================================
1 45503 9044 yes yes none reject reachable 4
Condition field shows "reject" for more then 15 to 20 minute then after it changes to
"sys.peer" after then only sync happens.
I have opened the port 123 for ntp. Still it shows reject
Please let me know reason for this to fix the issue
Why do you believe there is an issue to be fixed?
Ntpd takes a certain amount of time to sync after a restart.
You could add a few more ntp sources. Three sources are not
enough, four is good, five is safer.
One of my servers, ntp-dev 4.2.7p433, was restarted on Mar 15:
time remote st reach offset
18:36 oPPS 0 377 -0.001
reboot
18:42 PPS 0 0 0.000
18:48 oPPS 0 37 -60.233
18:54 oPPS 0 377 -0.004
19:00 oPPS 0 377 -0.001
Other servers without pps take a few minutes longer to sync.
David

Hi All,
When ever I configure ntp client ,then its takes more time even if 7minute to 8
minute difference is there between client and server.
Please provide me the configuration which will sync within less time.
Currently ntp.drift file is empty.shall we need to modify the same?
Current NTP Client configuration is :
server 10.16.188.254
Add iburst to this line.
Since this is an internal server can you add any more NTP servers? One
is not a good number 3 is good and 4 is better. Never use 2.
server 127.127.1.0
fudge 127.127.1.0 stratum 10
Get rid of these last two lines. Unless the ntp client is serving time
elsewhere it's not needed.
restrict 10.16.188.254 mask 255.255.255.255 nomodify notrap noquery
restrict 127.0.0.1
