admasq

Domain adblocking with dnsmasq.

Setup

On a server with docker, run the daoo/admasq image as follows:

# docker run --publish $HOST_IP:53:53/udp \
    --cap-add=NET_ADMIN \
    --dns=$DNS_IP \
    --dns-search=$DNS_DOMAIN \
    --restart=always \
    --name=admasq \
    --detach \
    daoo/admasq:latest

Specifying the IP to listen on and the upstream DNS server explicitly avoids any conflicts with systemd-resolved.

Optionally, for automatic updates, enable the admasq.timer and admasq.service files in systemd.

Then setup your other clients to use the new DNS server by manual configuration and/or pushing the new DNS server by DHCP.
