## A command to squash all ads in all browsers

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

Simple, native and efficient **local ad blocker**. Bash script compatible with **MacOS**, **Linux**, **BSD** and **Windows Subsystem for Linux (WSL)**.

- Just **bash** 🤖.
- It affects **any browser** or software installed 😱.
- 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** 😎.
- Pure **Opensource** ❤️.

## 📟 Commands

### 📡 Update database

``` bash
maza update
```

### 🔨 Start

``` bash
sudo maza start
```

### 🛠 Stop

``` bash
sudo maza stop
```

### ⚖️ Status

``` bash
maza status
```

## ⚙️ Install or Update

### 😥 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 && sudo rm -rf /usr/local/bin/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 ~/.config/maza
```

## 🚫 Not blocking certain domains

Edit `~/.config/maza/ignore` and add the domains you want to ignore.

Example:

``` txt
ads-twitter.com
ads.twitter.com
```

By default, the following domains are ignored to avoid problems with the operating system.

``` txt
localhost
localhost.localdomain
local
broadcasthost
ip6-localhost
ip6-loopback
ip6-localnet
ip6-mcastprefix
ip6-allnodes
ip6-allrouters
ip6-allhosts
0.0.0.0
```

Finally update Maza to apply the changes.

``` bash
maza update
```

## 🎯 Add custom domains to block

If you want to include your own domains to be blocked, you can add them to `~/.config/maza/custom-domains`. They must each be on one line, ignoring end slash or protocol (`http` or `https`).

For example:

``` txt
beauty-tea.com
www.expaqua.cloud
ad.about.com
```

Then update the database to regenerate the list to include your domains.

```
maza update
```

## 🔒 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.

Replace this line:

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

with this:

```
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
brew install dnsmasq
```

#### 2 Configure

```
address=/.localhost/127.0.0.1
```
