Details
avmntpd is a new SNTP client daemon.
It is subscribed to the state_iface_inet state in the AVMIPC-Datastore and gets active when it turns CONNECTED.
Since fw 7.39 ~100k it is triggered by the STATE_IFACE_INET_FAMILY state instead.
It then performs a SNTP request to the time server and starts / restarts / controls chronyd on success and sets the avmipc
state STATE_SYSTEMTIMESTATUS_FBSTATE.
The job of avmntpd is apparently to quickly get a system time, while letting chronyd maintain its precision and distribution.
fw 7.39 help:
root@fritz:/var/mod/root# avmntpd -?
usage: avmntpd [options]
options:
-? - print this help
-s - stop daemon. (NOTSET)
-p STRING - Pidfile. ("/var/run/avmntpd.pid")
-D STRING - switch debug logs on. (FUNC)
start daemon: avmntpd
stop daemon : avmntpd -s
