raspapwebgui
=============
Started and modified from here http://sirlagz.net/2013/02/08/raspap-webgui/
Found this article very helpful for setting up DHCP (https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/install-software)
Requirements
============
A raspberry pi with raspbian running on it. You will need to ssh into it to set this up.
The Packages required for the WebGUI are:
* lighttpd
* php5-cgi
* isc-dhcp-server
* git
Steps
=====
1. Install required packages
`sudo apt-get install lighttpd php5-cgi git isc-dhcp-server`
2. Enable php in lighttpd
```
sudo lighty-enable-mod fastcgi-php
sudo service lighttpd restart
```
3. Edit `/etc/sudoers` to allow the *www-data* user to call the necessary commands. Add the following line to the end of the file.
```
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
```
4. Once those modifications are done, git clone the files to `/var/www`. Make sure that there are no files in the `/var/www` directory. There was a default lighttpd index file that I had to delete.
`sudo git clone https://github.com/rjpcomputing/raspap-webgui.git /var/www`
5. Set the files ownership to `www-data` user.
`sudo chown -R www-data:www-data /var/www`
6. Configure a static IP for the Pi
* Edit `/etc/network/interfaces`
`sudo nano /etc/network/interfaces`
* Find and remove dhcp entry
`iface eth0 inet dhcp`
* Append new network settings
```
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
dns-nameservers 8.8.8.8 8.8.4.4
```
* Find and change `iface wlan0 inet manual` to `iface wlan0 inet dhcp`. This is under the wlan0 setup.
* Comment out `iface default inet dhcp` and `allow-hotplug wlan0` using the '#' character at the beginning of the line(s).
* Example of `/etc/network/interfaces` after all changes are made:
```
auto lo
iface lo inet loopback
#iface eth0 inet dhcp
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
dns-nameservers 8.8.8.8 8.8.4.4
auto wlan0
#allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
#iface default inet dhcp
```
7. Configure `dhcpd` by editing `/etc/dhcp/dhcpd.conf`
* `sudo nano /etc/dhcp/dhcpd.conf`
* Add the following to the end of the file
```
subnet 10.0.0.0 netmask 255.255.255.0
{
range 10.0.0.50 10.0.0.99;
option routers 10.0.0.254;
option domain-name "local";
option domain-name-servers 8.8.8.8, 8.8.4.4;
}
```
8. Open `/etc/default/isc-dhcp-server` and change the `INTERFACES=""` to `INTERFACES="eth0"`
`sudo nano /etc/default/isc-dhcp-server`
9. Install and configure the auto-reconnect WiFi script (wifi-check).
* Copy 'wifi-check' to `/usr/local/bin/wifi-check`
* `sudo cp /var/www/wifi-check /usr/local/bin/wifi-check`
* `sudo chmod +x /usr/local/bin/wifi-check`
* Add it to cron so it runs every 5 minutes
* `sudo crontab -e`
* Append the line `*/5 * * * * /usr/local/bin/wifi-check > /tmp/wificheck.log 2>&1` to the end of the file
* Save the file
* Reboot and it should be up and running!
`sudo reboot`
