dns-adblock

This repository contains the Ansible playbook that we use to generate the ad and tracker blocking files for our DNS over TLS / DNS over HTTPS, and VPN server (also known as VPN relay) based DNS blocking.

This is imported to our VPN servers frequently.

Lists

The following lists are what we import to our service. You can find these defined in inventory/group_vars for the server type you wish to view.

doh: DNS over HTTPS / DNS over TLS
relay: VPN servers (relays)

Trackers

We currently use these tracker blocklists with our service:

Building

The following steps are useful only if you wish to build the lists yourself.

The output files located in output/relay/ are what are imported onto our VPN servers.

Requirements

Ansible Core 2.12.x =<

Step by step

Ensure the values in group_vars/<group>.yml are up to date with any block lists
Ensure you have added any 'custom' extra lists or websites to block
Run the playbook to generate the lists:
- ansible-playbook -i inventory/ playbook.yml
- ansible-playbook -i inventory/ playbook.yml --tags=readme can be used to generate the README on its own
View the output (once pushed) at https://raw.githubusercontent.com/mullvad/dns-adblock/main/output/<group>.txt?raw=true
Run test script: cd scripts && ./check_zonedata.sh
Sign the outputted relay files with your GPG code signing key, for example:
- for list in adblock adult privacy gambling; do gpg2 --detach-sign --armor output/relay/relay_${list}.txt > output/relay/relay_${list}.txt.gpg; done
Verify the outputted GPG signed files, for example:
- for list in adblock adult privacy gambling; do echo "Verify: ${list}" && gpg2 --verify output/relay/relay_${list}.txt.gpg output/relay/relay_${list}.txt; done
