# Maza ad blocking – Like Pi-hole but local and using your operating system

Simple, native and efficient local advertising blocker. Compatible with OSX and Linux.

– 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 stroke.
– Opensource.
– Just bash.

## ?‍Run

### ? 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 OSX 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
“`

## ? Uninstall

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

## 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. Here’s an example for OSX.

### 1 Install

“`bash
brew install dnsmasq
“`

### 2 Configure

Edit the file.

“`
/usr/local/etc/dnsmasq.conf
“`

Add the following lines.

“`
conf-file=(your user path)/.maza/dnsmasq.conf
“`

Start DNSMASQ.

“`bash
sudo brew services stop dnsmasq
sudo brew services start dnsmasq
“`

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

Delete the list of OSX 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
“`

Refresh your DNS cache

“`bash
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
“`

### Bonus: dnsmasq is in charge of solving all DNS

Add in confiigure file: `/usr/local/etc/dnsmasq.conf`

“`
no-resolv
server=208.67.222.222
server=208.67.220.220
“`

### Bonus: dnsmasq have test domains

If you want all your `.localhost` domains, for example, point to localhost add in confiigure file: `/usr/local/etc/dnsmasq.conf`

“`
address=/.localhost/127.0.0.1
“`

## ⚠️ CAUTION

– Only compatible with Linux and OSX operating systems.
– Remember to make a backup copy of `/etc/hosts` in case of unforeseen circumstances, neither the project nor its author will be responsible for any possible repercussions derived from not carrying out this action.
