I'm looking for a network manager.
I would like to use ConnMan in an embedded system. It seems that it
provides most of the features I'm looking for, including 3G and VPN
But after some research it seems that there is maybe one missing point
in it. Let say I have the following setup :
* Ethernet connection as preferred connection
* 3/4G connection as backup/failover connection
My Ethernet is always on and dhcp server is properly providing IP, cable
is still plugged in, and power on the line is still there, but sometimes
the internet connectivity is lost. So in that case it ll switch to the
3G/4G connection. But then as soon as possible, when connectivity is
back online via the ethernet, I want to switch back to it for
performance and cost reason.
Is this supported by default, or is there a way to configure it that way ?
I found this
seems to say that it was not supported at that time, since there is no
periodic check (February 2013).
And also from the documentation :
Favorite (saved) networks that have autoconnect enabled are
considered when autoconnecting services. These services are marked
with '*' and 'A' in connmanctl, respectively. By default ConnMan
autoconnects these in the order they are shown in the list of
services until one of them gets connected. After that the
autoconnected service is in use and ConnMan won't select a new one
until the network goes out of range. When the service goes out of
range or gets disconnected from the network infrastructure side,
autoconnect is re-run and another favorite autoconnectable service
So I want to make sure I got the correct understanding on that ?
Yup, ConnMan doesn't do continuous online checks. I have experimented
with adding this functionality based on the current online check. But
looking back, it's not the best approach. I do think that this
functionality can be very useful though.
