Hi Vasyl,

I would go with ScanAsync and make the property signal working for all
technologies. That seems to be the best way forward in my opinion. If we
do a 2.x of ConnMan we can merge Scan and ScanAsync together and use a
parameter for the behavior.

If ConnMan crashes, something like systemd will probably restart.
ConnMan can't restart itself.

The error message indicates, that we have a problem finding a
empty IP range in the private address space (, ...).

So we either have a bug in the code trying to find an empty block
or the current network configuration is covering all the private address
ranges and the logic can't find any block.

Hard to tell without the log. Can you post the log output of ConnMan (or
a post a link the log)? Also the output of 'ip addr' and 'ip route'
would be handy.

Is it possible to get all network interfaces using connman? I tried to get
them through services, but for example, if I have eth1 not connected with a
cable (without inet addr in ifconfig) doesn't appear when I call services.

Thank you,
Alexandru Vasiu
