one-block-army

Adlist merger and whitelister
Created because of a small shortcoming in the adlist feature of RouterOS where you cannot whitelist hosts.

Install

General linux

• Clone the project git clone git@github.com:rogierknoester/one-block-army.git
• cargo build --release
• copy the binary to where you'd use it
• create a config file and point to it with the --config ./config.toml option

NixOS

Include the flake.nix in your flake.

{
    inputs.one-block-army.url = "github:rogierknoester/one-block-army";
    inputs.one-block-army.inputs.nixpkgs.follows = "nixpkgs";

    outputs = {one-block-army, ...}: {
      nixosConfigurations = {
        server-a = nixpkgs.lib.nixosSystem {
          system = "x86_64-linux";
          modules = [
            one-block-army.nixosModules.one-block-army
          ];
        };
      };
    }
}

Enable the service with

services.one-block-army = {
  enable = true;
  listen = "0.0.0.0";
  port = 8000;
  adlists = [
    "https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts"
    "https://blocklistproject.github.io/Lists/ads.txt"
    "https://raw.githubusercontent.com/hagezi/dns-blocklists/refs/heads/main/hosts/pro.plus.txt"
  ];

  whitelistedHosts = [
    "kagi.com"
    "sentry.io"
    "*.sentry.io" # globbing is supported
  ];
};

Post install

Once its running you'll need to configure your DNS server or adblocking list to use it. For example on RouterOS:

/ip dns adlist add url=http://server-a-ip:8000
