Is there a way to find the IP address of the desktop machine connected the android phone after USB tethering is turned on?
Does android assign a fixed IP address to the desktop? Or does it assign a dynamic address (dhcp)? Is there a PPP connection created between the phone and machine?
回答1:
With USB tethering it seems that all android devices use the same static addresses, the android device using tcpdump is 192.168.42.129
The attached device will get a DHCP provided address in the same address range.
I listen to a port on my android app and have a udev rule to push the dhclient address back to that port on my app.

AFAIK, in usb tethering mode the phone is acting as the computer's modem, so the PC's IP would be the phone's IP.
