When you plug a USB-to-Ethernet adaptor into your computer for the
first time, a new service entry appears in the Network Preferences
Panel. I have a potential client who moves laptops between stations
with USB-to-Ethernet adaptors. As laptops move from station to
station, they accumulate a lot of stale service entries in the
Network Preferences Panel (for each USB adaptor they've seen). I'm
looking for ways to remove these service entries shortly after a USB-
to-Ethernet adaptor is unplugged.
The reason that we retain the service entries is that we want to
ensure that every time you use that same adaptor you end up with the
same configuration (so it's expected behavior).
I'm familiar with accessing the System Configuration Framework and
helped develop an Open Source driver for USB-to-Ethernet adaptors,
so I am able to tweak the driver if that would help.
Driver changes won't help.
I can imagine a small faceless application that listens for device
notifications and walks the network service order looking for
inactive service entries that meet some criteria and removes them,
but that seems a little awkward.
But that's essentially what you'd need to do. ... and going a bit
deeper, you'd probably want to remove the adapter-->enX mapping
(something that would best be followed by a reboot).
Is there a more direct way to limit the persistence of such entries
before they pile up?
