Change the location when not connected to any wifi (just wired)

[tleveque23]

It would be very great if the location can be change automatically when no wifi network is connected.
In my case, I am connected to my wifi network at home, then on my iPhone in the train, but at the office, I don't use any wifi. I am connected by ethernet. So I need to change the location to not use my own home dns.

Hi Thierry,

Unfortunately, OS X doesn't update com.apple.airport.preferences.plist when AirPort goes off, it doesn't seem possible to detect it by observing changes in that file. I like the feature, if you're up to implementing it, feel welcome.

Perhaps it could watch for preferences.plist along with com.apple.airport.preferences.plist.

I don't know. I am not a OsX developper. Just Java and Angular........ I am just a user.
There is also probably other way to know if connected to a wire network. Like looking at the interfaces.
You can probably do something like:
networksetup -listnetworkserviceorder | grep 'Hardware Port'
Then use the interface name in the result with ifconfig to look at its status.....
