# Raspberry Pi Ad Blocker
**A black hole for ads, hence Pi-hole**
![Pi-hole](http://i.imgur.com/wd5ltCU.png)
The Pi-hole is a DNS/Web server that will **block ads for any device on your network**.
## Coverage
Featured on [MakeUseOf](http://www.makeuseof.com/tag/adblock-everywhere-raspberry-pi-hole-way/) and [Lifehacker](http://lifehacker.com/turn-a-raspberry-pi-into-an-ad-blocker-with-a-single-co-1686093533)!
## Automated Install
# Automated Install
##### Designed For Raspberry Pi B, B+, 2, and Zero (with an Ethernet adapter)
1. Install Raspbian
2. Set a **static** IP address
3. Run the command below
2. Run the command below
```curl -s "https://raw.githubusercontent.com/jacobsalmela/pi-hole/master/automated%20install/basic-install.sh" | bash```
### ```curl -L install.pi-hole.net | bash```
Once installed, **configure any device to use the Raspberry Pi as its DNS server and the ads will be blocked**. You can also configure your router's DHCP options to assign the Pi as clients DNS server so they do not need to do it manually.
Once installed, [configure your router to have **DHCP clients use the Pi as their DNS server**](http://pi-hole.net/faq/can-i-set-the-pi-hole-to-be-the-dns-server-at-my-router-so-i-dont-have-to-change-settings-for-my-devices/) and then any device that connects to your network will have ads blocked without any further configuration. Alternatively, you can manually set each device to [use the Raspberry Pi as its DNS server](http://pi-hole.net/faq/how-do-i-use-the-pi-hole-as-my-dns-server/).
## Pi-hole Is Free, But Powered By Your Donations

## Partnering With Optimal.com
Pi-hole will be teaming up with [Rob Leathern's subscription service to avoid ads](https://medium.com/@robleathern/block-ads-on-all-home-devices-for-53-18-a5f1ec139693#.gj1xpgr5d). This service is unique and will help content-creators and publishers [still make money from visitors who are using an ad ablocker](http://techcrunch.com/2015/12/17/the-new-optimal/).
## Technical Details
The Pi-hole is an **advertising-aware DNS/Web server**. If an ad domain is queried, a small Web page or GIF is delivered in place of the advertisement. You can also [replace ads with any image you want](http://pi-hole.net/faq/is-it-possible-to-change-the-blank-page-that-takes-place-of-the-ads-to-something-else/) since it is just a simple Webpage taking place of the ads.
A more detailed explanation of the installation can be found [here](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0).

## Gravity
The [gravity.sh](https://github.com/jacobsalmela/pi-hole/blob/master/gravity.sh) does most of the magic. The script pulls in ad domains from many sources and compiles them into a single list of [over 1.6 million entries](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0).

The script pulls in ad domains from many sources and compiles them into a single list of [over 1.6 million entries](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0) (if you decide to use the [mahakala list](https://github.com/jacobsalmela/pi-hole/commit/963eacfe0537a7abddf30441c754c67ca1e40965)).
## Whitelist and blacklist
You can add a `whitelist.txt` or `blacklist.txt` in `/etc/pihole/` and the script will apply those files automatically.
You can add a `whitelist.txt` or `blacklist.txt` in `/etc/pihole/` and the script will apply those files automatically. Put one domain per line.
## Web Interface
I am also working on a [Web interface](https://github.com/jacobsalmela/AdminLTE#pi-hole-admin-dashboard) so you can view stats and change settings.
The [Web interface](https://github.com/jacobsalmela/AdminLTE#pi-hole-admin-dashboard) will be installed automatically so you can view stats and change settings. You can find it at:
## Custom Config File
If you want to use your own variables for the gravity script (i.e. storing the files in a different location) and don't want to have to change them every time there is an update to the script, create a file called `/etc/pihole/pihole.conf`. In it, you should add your own variables in a similar fashion as shown below:
`http://192.168.1.x/admin/index.php`
```
origin=/var/run/pihole
adList=/etc/dnsmasq.d/adList
### API
A basic read-only API can be accessed at `/admin/api.php`. It returns the following JSON:
```JSON
{
"domains_being_blocked": "136708",
"dns_queries_today": "18108",
"ads_blocked_today": "14648",
"ads_percentage_today": 80.892423238348
}
```
See [this PR](https://github.com/jacobsalmela/pi-hole/pull/20) for more details.
![Web](http://i.imgur.com/m114SCn.png)
### How It Works
A technical and detailed description can be found [here](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0)!
## Real-time Statistics
You can view [real-time stats](http://pi-hole.net/faq/install-the-real-time-lcd-monitor-chronometer/) via `ssh` or on an [2.8" LCD screen](http://amzn.to/1P0q1Fj). This is accomplished via [`chronometer.sh`](https://github.com/jacobsalmela/pi-hole/blob/master/advanced/Scripts/chronometer.sh).
![Pi-hole LCD](http://i.imgur.com/nBEqycp.jpg)
## Help
- See the [Wiki](https://github.com/jacobsalmela/pi-hole/wiki/Customization) entry for more details
- There is also an [FAQ section on pi-hole.net](http://pi-hole.net)
## Other Operating Systems
This script will work for other UNIX-like systems with some slight **modifications**. As long as you can install `dnsmasq` and a Webserver, it should work OK. The automated install only works for a clean install of Raspiban right now since that is how the project originated.
