RIOT/tests/gnrc_sock_dns

Overview

This folder contains a test application for RIOT's sock-based DNS client.

How to test with native

Setup up a tap interface:

$ sudo ip tuntap add dev tap0 mode tap user $(id -u -n)
$ sudo ip a a 2001:db8::1/64 dev tap0
$ sudo ip link set up dev tap0

Start dnsmasq (in another console):

$ sudo dnsmasq -d -2 -z -i tap0 -q --no-resolv \
    --dhcp-range=::1,constructor:tap0,ra-only \
    --listen-address 2001:db8::1 \
    --host-record=example.org,10.0.0.1,2001:db8::1

(NetworkManager is known to start an interfering dnsmasq instance. It needs to be stopped before this test.)

Then run the test application

$ make term

The application will take a little while to auto-configure it's IP address. Then you should see something like

example.org resolves to 2001:db8::1
