Solved Automating 'dhclient ue0' when tethering USB

And where did you put the rule.
The reason you use /usr/local/etc/devd is so you can easily spot your works. Instead of polluting system rules in /etc/devd.

cat /usr/local/etc/devd/usb_tethering.conf:-

Code: 
attach 100 {
    match "device-name" "ue0";
    action "/sbin/dhclient ue0";
};

This worked for some time, but no longer does. Now I need to run dhclient ue0 after I have attached a USB cable to my phone and enabled USB tether.

It just stopped working after a power cut and reboot.

I'll test this method and I'll let you know.
However have you checked on your phone too?

There is nothing to check on my phone.

All I do is enable Tethering USB on my phone when I have connected the the USB cable to it.

What happened previously was that dhclient ue0 would automatically run, but now, for some reason I need to do it manually.

The solution you proposed doesn't work for me too.
Dhclient is not triggered when I plug my phone. 🤔

I guess the method has changed. 🤷‍♂️
 
I used to connect to the internet over USB tethering a few years ago. The devd configuration used then is still on my system (15.1-RELEASE-p2 now), and still working:

/usr/local/etc/devd/usb_tethering.conf
Code: 
# Configure USB tethering devd event. Example taken from https://wiki.freebsd.org/Devd

notify 20 {
    match "system"        "ETHERNET";
    match "type"        "IFATTACH";
    match "subsystem"    "ue[0-9]+";
    action "/sbin/dhclient $subsystem";
};

Upon activation of the USB tethering on my phone, an IP address is assigned automatically:
Code: 
% ifconfig ue0
ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=0
    ether a0:cf:76:12:d4:44
    inet 192.168.53.137 netmask 0xffffff00 broadcast 192.168.53.255
    inet6 fe80::cf:76ff:fe12:d444%ue0 prefixlen 64 scopeid 0x7
    nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

There is unusual activity on the console, printed repeatedly. Despite the messages, the internet connection remains stable, using it to access the forums and write this post.
Code: 
%  dmesg  -a
