A few posts ago, I wrote about making android’s dnsmasq more usable by turning on local hostname resolution. Since I use my android phone as a pocket server, dnsmasq plays a vital role here.
However, one thing was bad – whenever I used usb tether connection to my PC, the whole dns thingie did not work. Why?
So, a little theory. When I enable the wifi ap mode, an interface called ap0 is brought up with a static ip 192.168.43.1.
Whenever I turn on usb tethering, usb0 pops into the existence with ip 192.168.42.129.
(On other mobile phones these settings can differ)
Fine, so when we resolve our pocket server from within the usb0 network, we want to get 192.168.42.129, and when via a wireless network – 192.168.43.1
I started by adding two distinct entries in /etc/hosts
192.168.43.1 anomalia anomalia.portable git.anomalia p.anomalia 192.168.42.129 anomalia anomalia.portable git.anomalia p.anomalia
Did it work? No! Why?
