## A command to squash all ads in all browsers

```shell
sudo maza start
```

Like Pi-hole but local and using your operating system.

Simple, native and efficient **local ad blocker**. Bash script compatible with **MacOS**, **Linux** and **BSD**.

- You **don't have to install any browser extensions or applications**, you just use the tools of your operating system.
- You update the list of DNS to be blocked with a **single command**.
- It affects **any browser** or software installed.
- Pure **Opensource**.
- Just **bash**.

## 📟 Commands

### 📡 Update database 

``` bash
maza update 
```

### 🔨 Start

``` bash
sudo maza start 
```

### 🛠 Stop

``` bash
sudo maza stop 
```

### ⚖️ Status

``` bash
maza status 
```

## ⚙️ Install 

### 😥 Requirements 

- **bash** 4.0 or higher
- **curl**
- Only macOS users, **gsed**: `brew install gnu-sed`

Then you do this.

``` bash
curl -o maza https://raw.githubusercontent.com/tanrax/maza-ad-blocking/master/maza && chmod +x maza && sudo mv maza /usr/local/bin
```

Optional but recommended, make a backup of your hosts file.

``` bash
sudo cp /etc/hosts /etc/hosts.backup
```

## 🤖 Auto update of domains to be blocked

Open your `cron`.

``` bash
crontab -e
```

Add the following line at the end.

```
@daily maza update
```

## 🔪 Uninstall

``` bash
sudo rm /usr/local/bin/maza && sudo rm -r ~/.maza
```

## 🔒 Alternative DNS list

By default the Yoyo DNS list (Peter Lowe) is used. If you want to use another list, like Steven Black's for example, you must modify the variable in line 7. 

It would go from:

```
URL_DNS_LIST="https://pgl.yoyo.org/adservers/serverlist.php?showintro=0&mimetype=plaintext"
```

To the following:

```
URL_DNS_LIST="https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts"
```

## DNSMASQ

Unfortunately the hosts file does **not support sub-domains (wildcards)**, which is necessary to correctly filter all DNS. You will **need to install locally a server** for that purpose, Maza supports the **Dnsmasq** format.

[MacOS](#MacOS)

[Linux](#user-content-linux-debianubuntu)

### MacOS

#### 0 Update Maza

```bash
maza update
```

#### 1 Install

```bash

```

#### 2 Configure

Edit the file.

#### 3 Tell your OS to use your DNS server

Delete the list of macOS DNS servers and add the 3 addresses. The first one will be your local server, and the other 2 belong to OpenDNS, which you can use any other.

```bash
127.0.0.1
208.67.222.222
208.67.220.220
