how to know if my computer is being syncing with ntp server or not.

run "ntpq -pn" and look for an entry marked with *'s:

Code:

     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
*10.101.168.249  172.16.83.1      4 u   83 1024  377    1.515   -1.777   0.284

I can't * on any of the entry where i have configured NTP.

Below output is of one pc

Quote:

[root@GAIDL-5001 ~]# ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================
120.88.47.10 .INIT. 16 u - 1024 0 0.000 0.000 0.000
[root@GAIDL-5001 ~]

Below output is of second pc

Quote:

[sachin.davra@GAIDL-5015 ~]$ ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================
120.88.46.10 103.1.106.69 2 u 83m 1024 20 22.645 408.725 0.518

OK, so for the first, the "16" number means that the remote server isn't responding / is unreachable on the network.

For the second, less immediately obvious. Stop the NTP service and run "ntpdate -d 120.88.46.10" to see the debug about the decision to use that server.
