Resources for blocking ads using a local Unbound DNS server, as well as setting up a pixelserver with lighttpd.
We include the following scripts
-
gen-adblock-spoof.sh
This uses host file data from https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts to create local-data that redirects ad-domains to127.0.0.2. Note: it assumes the hostfile uses0.0.0.0as the ip .
A custom redirection ip address can be specified in the first argument. -
gen-adblock-refuse.sh
This uses host file data from https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts to create local-data that responds to ad-domains withNXDOMAIN -
hosts-to-unbound.sh
Reads from/etc/hostsand creates both local-data (forward) and local-data-ptr (reverse) records for each entry. Note: it assumes that records contain only two fields per line.
An alternative file can be specified by the first argument -
hosts-to-unbound-noptr.sh
Reads from/etc/hostsand creates only local-data (forward) records for each entry.
An alternative file can be specified by the first argument.
To use these adblock examples, place them in /etc/unbound/local.d/

lighttpd/adblock.conf is an example configuration file for running a self-contained pixel-server.
This uses lighttpd and listens on 127.0.0.2.
For this to work, you cannot have any other web servers listening on 0.0.0.0
The lighttpd server redirects all images to a 1x1 png file, all javascript files to a script that runs console.log("Adblock); and everything else to an empty html page.
To use it:
sudo lighttpd -f lighttpd/adblock.conf
you may wish to create a systemd unit etc.
