How to check NTP work or not?

[Harry Hoffman]

Try this (as root or with sudo),

service ntpd stop
ntpdate clock.redhat.com
ntpdate clock.udell.edu
service ntpd start
ntpq -p

If the "reach" column in the output of ntpq -p is greater then 0 then
ntp is working.

Have you changed the default ntp.conf?


HTH,
