How do I find out if dnsmasq is running? I have dnsmasq available on my Android (stock ROM 4.4.2 Note2) and would like to know how I can tell if it's running and what settings its currently using?
If you're rooted, go to /system/bin/ and find dnsmasq if it's in there. Alternatively, you can also check /xbin (but, that's unlikely to be there).

If you managed to find one in either path - you now use a terminal emulator and type su first and enter, then type dnsmasq -d to see if the process will be invoked properly. It should also run with its default settings depending on how it was compiled.
