PRECAUTION
|
|
|
|
Remove the both '/sbin/hwclock ...' entries from /etc/rc.shutdown
|
|
and /etc/rc. No other software should manipulate the system hardware
|
|
clock if chronyd is running.

|
Chrony is a pure Network time protocol (NTP) server, that mean it
|
|
provides it's services on port 123/UDP. Utilities like rdate uses
|
|
the time protocol on port 37/TCP. To use rdate with chrony you must
|
|
add the following line to the /etc/inetd.conf of your chrony server
|
|
and run inetd:
|
|
|
|
time stream tcp nowait root internal
|
|
|
|
To avoid this, I recommend the use of the NTP utility msntp to sync
|
|
your clients with your chrony server or better run chrony on all of
|
|
your clients.
|
|
|
|
The start script /etc/rc.d/chronyd has a online and a offline option.
|
|
Use this in your ip-up/ip-down scripts to tell chrony whether we are
|
|
online or offline.
