Hi folks,
Obtaining an Internet access from an iOS device connected via USB is currently
quite a pain.
The flow is supposed to be something like:
1. load the ipheth module
2. plug in the iOS device with tethering enabled
3. a new ueN interface is created
4. dhclient ueN
and you should have a new gateway. At least this is what I expect, which is
similar to what happens when connecting an Android device with tethering
enabled, the only difference being you have to use the urndis module.
After step 3 instead the ipheth module is not capable of creating the
interface, and you have to actually configure the device manually as explained
in the ipheth(4) BUG note, using `usbconfig -d <unit>.<addr> 2 set_config 3`.
This triggers an authentication request on the iPhone, and after that the
interface is eventually created, but the dhclient is not able to obtain a lease
with it, "No DHCPOFFERS received”.
Digging around the web you’ll eventually find this guide [1] which, even though
it is quite old (10 yrs now), points to the right direction: usbmuxd and
libimobiledevice.
The usbmuxd is available as a port now, under comms/usbmuxd (not maintained
though). Install, run the daemon, plug the phone again and you’ll get your
interface. This time dhclient is able to obtain a lease, but you’ll not get
internet out of that (at least, I’m not):
```

Long story short: do we want to work on this issue? I’m available for helping,
but I need some guidance.
Greetings,
