# `$ raspap-webgui` [![Release 1.0](https://img.shields.io/badge/Release-1.0-green.svg)](https://github.com/billz/raspap-webgui/releases)
A simple, responsive web interface to control wifi, hostapd and related services on the Raspberry Pi.

This project was inspired by a [**blog post**](http://sirlagz.net/2013/02/06/script-web-configuration-page-for-raspberry-pi/) by SirLagz about using a web page rather than ssh to configure wifi and hostapd settings on the Raspberry Pi. I mostly just prettified the UI by wrapping it in [**SB Admin 2**](https://github.com/IronSummitMedia/startbootstrap-sb-admin-2), a Bootstrap based admin theme :smile:

We'd be curious to hear about how you use this with your own Pi-powered access points. Ping us on Twitter ([**@billzimmerman**](https://twitter.com/billzimmerman) and [**@SirLagz**](https://twitter.com/SirLagz)). Until then, here are some screenshots:

## Prerequisites
You need to install some extra software in order for the Raspberry Pi to act as a WiFi router and access point. If all you're interested in is configuring your RPi as a client on an existing WiFi network, you can skip this step. 

There are many guides available to help you select a WiFi adapter, install a compatible driver, configure HostAPD and so on. The details are outside the scope of this project, although I've had consistently good results with the [**Edimax Wireless 802.11b/g/n nano USB adapter**](http://www.edimax.com/edimax/merchandise/merchandise_detail/data/edimax/global/wireless_adapters_n150/ew-7811un) – it's small, cheap and easy to work with.

To configure your RPi as a WiFi router, either of these resources will start you on the right track: 
* [**How To : Use The Raspberry Pi As A Wireless Access Point/Router Part 1**](http://sirlagz.net/2012/08/09/how-to-use-the-raspberry-pi-as-a-wireless-access-pointrouter-part-1/)
* [**How-To: Turn a Raspberry Pi into a WiFi router**](http://raspberrypihq.com/how-to-turn-a-raspberry-pi-into-a-wifi-router/) (uses isc-dhcp-server instead of dnsmasq)

After you complete the intial setup, you'll be able to administer these services using the web UI.

## Installation
Start off by installing lighttpd and php5.
```sh
$ sudo apt-get install lighttpd php5-cgi
```
After that, enable PHP for lighttpd and restart it for the settings to take effect.
```sh
sudo lighty-enable-mod fastcgi-php
sudo /etc/init.d/lighttpd restart
```
Now comes the fun part. For security reasons, the `www-data` user which lighttpd runs under is not allowed to start or stop daemons, or run commands like ifdown and ifup, all of which we want our page to do.
So what I have done is added the `www-data` user to the sudoers file, but with restrictions on what commands the user can run.
Add the following to the end of  `/etc/sudoers`: 

```sh
www-data ALL=(ALL) NOPASSWD:/sbin/ifdown wlan0,/sbin/ifup wlan0,/bin/cat
/etc/wpa_supplicant/wpa_supplicant.conf,/bin/cp /tmp/wifidata 
/etc/wpa_supplicant/wpa_supplicant.conf,/sbin/wpa_cli scan_results,
/sbin/wpa_cli scan,/bin/cp /tmp/hostapddata /etc/hostapd/hostapd.conf,
/etc/init.d/hostapd start,/etc/init.d/hostapd stop,/etc/init.d/dnsmasq start,
/etc/init.d/dnsmasq stop,/bin/cp /tmp/dhcpddata /etc/dnsmasq.conf
```

Once those modifications are done, git clone the files to `/var/www`.
```sh
sudo git clone https://github.com/billz/raspap-webgui /var/www
```
Set the files ownership to `www-data` user.
```sh
sudo chown -R www-data:www-data /var/www
```
Move the RaspAP configuration file to the correct location
```sh
sudo mkdir /etc/raspad
sudo mv /var/www/raspad.php /etc/raspad/
sudo chown -R www-data:www-data /etc/raspad
```
Reboot and it should be up and running!
```sh
sudo reboot
```

The default username is 'admin' and the default password is 'secret'.

## Optional services
OpenVPN and TOR are two additional services that run perfectly well on the RPi, and are a nice way to extend the usefulness of your WiFi router. I've started on interfaces to administer these services. Not everyone will need them, so for the moment they are disabled by default. You can enable them by changing these options in `index.php`:

```sh
// Optional services, set to true to enable.
define('RASPI_OPENVPN_ENABLED', false );
define('RASPI_TORPROXY_ENABLED', false );
```
Please note that these are only UI's for now. If there's enough interest I'll complete the funtionality for these optional admin screens.

## How to contribute

1. File an issue in the repository, using the bug tracker, describing the
   contribution you'd like to make. This will help us to get you started on the
   right foot.
2. Fork the project in your account and create a new branch:
   `your-great-feature`.
3. Commit your changes in that branch.
4. Open a pull request, and reference the initial issue in the pull request
   message.
