[systemd-devel] Mobile phone USB tethering

[Thomas Köller]

I have a problem using a network interface created by using my mobile 
phone's USB tethering function. I am normally using my laptop's built-in 
wifi adapter, and this works flawlessly. If I connect my mobile phone 
via USB and enable its 'USB tethering' function, the network interface 
is created and even successfully configured (via the phones DHCP 
server), however, systemd-networkd-wait-online seems to not recognize it 
and times out. This is what it says:

root@yoga:/etc/systemd/system# journalctl -l -b -u 
systemd-networkd-wait-online.service
Jun 26 13:47:19 yoga systemd[1]: Starting 
systemd-networkd-wait-online.service - Wait for Network to be Online...
Jun 26 13:49:20 yoga systemd-networkd-wait-online[1273]: Timeout 
occurred while waiting for network connectivity.
Jun 26 13:49:20 yoga systemd[1]: systemd-networkd-wait-online.service: 
Main process exited, code=exited, status=1/FAILURE
Jun 26 13:49:20 yoga systemd[1]: systemd-networkd-wait-online.service: 
Failed with result 'exit-code'.
Jun 26 13:49:20 yoga systemd[1]: Failed to start 
systemd-networkd-wait-online.service - Wait for Network to be Online.

As already mentioned, the interface does not seem to have any issues and 
is fully functional after systemd-networkd-wait-online.service timed out.

I am using systemd 259 (259.6-1.fc44). The built-in wifi adapter has 
been disabled by setting 'ActivationPolicy = down' in its .network file.
