Hi Alastair, here a better explanation of what I'd like to do:
I'm trying to use dbus with C++/QT under FSO, to test it I'm writing a
simple gui that is able to turn on/off the bluetooth adapter, and to spawn a
pan connection to my nap gentoo boxes. This is really simple with dbus, and
works fine with dbus-send or mdbus, now I'd like to support network
configuration to have different pan profiles, with or without dhcp, with or
without default routing and so on.
So actually should I modify /etc/network/interfaces directly in my
application or spawn some external script that does this with sed and after
launch ifdown/ifup bnep0?
This seems not much elegant to me, and to avoid mistakes on the
configuration file, I should read busybox c code to understand how it read
that file (a curiosity, there is a doc file in busybox that says please do
not use ifup/ifdown approach:))
The problem become bigger if I want to add a pan server option and so change
ip forwarding and iptables rules, launch dhcp or change the its ip range,
and so on...
What's we may expect in the future? would be nice to have frameworkd offer
nice api to hide and abstract all this tasks? should we ask for
connman/networkmanager official/default support in OE?
