[Dnsmasq-discuss] dnsmasq using dnscrypt

dnsmasq (2.60-2 on arch 32bit) is supposed to be listening on 127.0.0.1
127.0.0.2 is a second loopback lo:1 on which dnscrypt is listening on, 
to not interfere with dnsmasq.

I got it to work now. Instead of using the "interface" option to define 
the devices to listen on (seems to auto include all loopback devices, 
though dnsmasq couldn't have actually listened to 127.0.0.2 since it was 
already locked by dnscrypt ), I used the 'listen-address' option to 
define all the ips of my devices. leaving out 127.0.0.2 obviously.

now dnsmasq stopped complaining and all my dns traffic is nicely 
encrypted as it should be. Cheers!

Thanks anyway for your time and maybe this is helpful to someone else 
having similar trouble
