Hi,
I have configured the ntp server and ntp client on two machine.
Both are communicating properly. I would like to test when the
connectivity between those two goes down, after how much time the
"reach" option in ntpq -p command becomes zero.
For that I stopped the ntp server and I executed the ntpq -p in
client's console,
The reach option will still keep on increase to 377 then gradually
decreases to zero. The time duration to come to zero is almost 20
minute.
Can we reduce the time gap ?

Biswajit,
Look for a value not equal to 377, rather than 0. Possibly 376 would be
the first indication of a problem.
20 minutes (actually 1024 seconds) is the polling interval which will be
reached in a stable default configuration, so as others have said,
reduce the value of maxpoll for servers which are local to your network
(i.e. not public servers). On my own network, I typically have maxpoll
set to 5 for local servers, and minpoll set to 10 for Internet servers.
