Question Q1: In my configuration, i set
socket_domain limited to ipv4, therefore, i don't understand why daemon
try to open ipv6 socket ???, is it one error ???
Question Q2: according documentation, it seems possible to listen on
many ipv4 sockets.
In my configuration , i have set 2 ipv4 addresses, but it seems that
only localhost is used ???? because...

For DNS point of vue, my configuration listen address is correctly
resolved by DNS, because ...
ansible@hn-cubietruck-300:~$ sudo ping

Ans of course, this ipv4 is on local ip address

Question Q3: I set log file into log_dest via ....
log_dest /var/log/mosquitto/log_mosquitto.log
Why in previous command, my configuration for logfile does not
appear to be taken into account ?
Question Q4: After killing process, is seems not possible to start
daemon with standard command, (I am using sysvinit, not systemd),
because ...
