If ntp perceives that a time server is more than 1000 seconds different from everybody else it ignores the server and labels it insane.

I usually do not post comments about please read the manual, but if you are doing sysadmin and asking these questions, then please read your docset. System time is important to a lot of things. And the ntp interface supports commands like: ntptrace, ntpd, ntpq.

When you do not know what you are doing you can break a lot, quickly. And end up with interesting things like future dated files. And cron jobs and daemons that run incorrectly.

Hi Jim,

thx for the reply. actually i have doc which only mentioned how to configure it but nothing mention how to check if it working properly.

i have done the configuration but i am not sure if both are configured correctly and in working state.

i googled about ntp and i came to know about those command.
so insane here means that IP is not working ?

also what does below command is doing i am not able to understand..

ntpq -c peers 10.176.14.24

thx
