Maybe I'm missing something obvious... or I'm trying to do the
impossible... (neither would be a first for me unfortunately ;^)
Is there an easy way... or I guess even a hard way if necessary... to
determine which network interface a connection is using?
The scenario is a hierarchy of interfaces are defined in system
preferences Ethernet, then AIrport, then one or more modem dial-up
configurations. I need to know which one is being used to connect to
a specified host.
I'd hoped that the SCNetworkReachability APIs might help, but it only
appears to tell if a destination is reachable and if it would require
some type of connection.
My application already makes periodic network calls using CFNetwork.
Is it possible to determine which interface a CFReadStream is using?
And if so, can that result then be resolved back to the user visible
name from System Preferences... especially if the interface used is a
dial-up connection.
Is any of this even possible?
Any ideas or suggestions would be greatly appreciated.
