📟 Commands

📡 Update database

maza update

🔨 Start

sudo maza start

🛠 Stop

sudo maza stop

⚖️ Status

maza status

⚙️ Install or Update

😥 Requirements

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

Then you do this.

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.

sudo cp /etc/hosts /etc/hosts.backup

🤖 Auto update of domains to be blocked

Open your cron.

crontab -e

Add the following line at the end.

@daily maza update

Some users have reported problems on MacOS. Fixed with TERM=dumb.

TERM=dumb
@daily maza update

🔪 Uninstall

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:

ads-twitter.com
ads.twitter.com

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

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.

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:

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.

0 Update Maza

maza update

1 Install

brew install dnsmasq

2 Configure

Edit the file.

/usr/local/etc/dnsmasq.conf

Start DNSMASQ.

sudo brew services stop dnsmasq
sudo brew services start dnsmasq

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.

127.0.0.1
208.67.222.222
208.67.220.220
