I have an Android device that runs Android9 and also another Android device that runs Android6 on it. I shared Android9’s internet to Android6 through a wifi connection. Then I shared the Android6’s internet to my computer (runs linux) through
USB Tethering option. Then on my computer, I run the command
sudo nmap -sn <my_network_address>
It only showed my Android6’s ip address and my computer’s ip address. It does not show my Android9 on that list.
I want to know why do this happen.
Thanks in advance.
