$raspap Release 2.0 Awesome Sponsor

A simple, responsive web interface to control wifi, hostapd and related services on the Raspberry Pi.

This project was inspired by a blog post by SirLagz about using a web page rather than ssh to configure wifi and hostapd settings on the Raspberry Pi. I began by prettifying the UI by wrapping it in SB Admin 2, a Bootstrap based admin theme. Since then, the project has evolved to include greater control over many aspects of a networked RPi, better security, authentication, a Quick Installer, support for themes and more. RaspAP has been featured on sites such as Instructables, Adafruit, Raspberry Pi Weekly and Awesome Raspberry Pi and implemented in countless projects.

We'd be curious to hear about how you use this with your own RPi-powered projects. Until then, here are some screenshots:

Contents

Prerequisites

Start with a clean install of the latest release of Raspbian (currently Buster). Raspbian Buster Lite is recommended.

  1. Update Raspbian, including the kernel and firmware, followed by a reboot:
sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot

  1. Set the WiFi country in raspi-config's Localisation Options: sudo raspi-config

  2. If you have an older Raspberry Pi without an onboard WiFi chipset, the Edimax Wireless 802.11b/g/n nano USB adapter is an excellent option – it's small, cheap and has good driver support.

With the prerequisites done, you can proceed with either the Quick installer or Manual installation steps below.

Quick installer

Install RaspAP from your RaspberryPi's shell prompt:

curl -sL https://install.raspap.com | bash

The installer will complete the steps in the manual installation (below) for you.

After the reboot at the end of the installation the wireless network will be configured as an access point as follows:

  • IP address: 10.3.141.1
    • Username: admin
    • Password: secret
  • DHCP range: 10.3.141.50 to 10.3.141.255
  • SSID: raspi-webgui
  • Password: ChangeMe

Note: As the name suggests, the Quick Installer is a great way to quickly setup a new AP. However, it does not automagically detect the unique configuration of your RPi. Best results are obtained by connecting an RPi to ethernet (eth0) or as a WiFi client, also known as managed mode, with wlan0. For the latter, refer to this FAQ. Please read this before reporting an issue.

Simultaneous AP and Wifi client

RaspAP lets you easily create an AP with a Wifi client configuration. With your RPi configured in managed mode, enable the AP from the Advanced tab of Configure hotspot by sliding the Wifi client AP mode toggle. Save settings and start the hotspot. The managed mode AP is functional without restart.

Note: For a Raspberry Pi operating in managed mode without an eth0 connection, this configuration must be enabled before a reboot.

Support us

RaspAP is free software, but powered by your support. If you find RaspAP useful for your personal or commercial projects, please become a sponsor or make a one-time donation with Beerpay. Either option makes a big difference!

Manual installation

These steps apply to the latest release of Raspbian (currently Buster). Notes for previously released versions are provided, where applicable. Start off by installing git, lighttpd, php7, hostapd and dnsmasq.

sudo apt-get install git lighttpd php7.1-cgi hostapd dnsmasq vnstat

Note: for Raspbian Stretch, replace php7.1-cgi with php7.0-cgi. For Raspbian Jessie and older versions, use php5-cgi. After that, enable PHP for lighttpd and restart it for the settings to take effect.

sudo lighttpd-enable-mod fastcgi-php
sudo service 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:

www-data ALL=(ALL) NOPASSWD:/sbin/ifdown
www-data ALL=(ALL) NOPASSWD:/sbin/ifup
www-data ALL=(ALL) NOPASSWD:/bin/cat /etc/wpa_supplicant/wpa_supplicant.conf
www-data ALL=(ALL) NOPASSWD:/bin/cat /etc/wpa_supplicant/wpa_supplicant-wlan[0-9].conf
www-data ALL=(ALL) NOPASSWD:/bin/cp /tmp/wifidata /etc/wpa_supplicant/wpa_supplicant.conf
www-data ALL=(ALL) NOPASSWD:/bin/cp /tmp/wifidata /etc/wpa_supplicant/wpa_supplicant-wlan[0-9].conf
www-data ALL=(ALL) NOPASSWD:/sbin/wpa_cli -i wlan[0-9] scan_results
www-data ALL=(ALL) NOPASSWD:/sbin/wpa_cli -i wlan[0-9] scan
www-data ALL=(ALL) NOPASSWD:/sbin/wpa_cli -i wlan[0-9] reconfigure
www-data ALL=(ALL) NOPASSWD:/bin/cp /tmp/hostapddata /etc/hostapd/hostapd.conf
www-data ALL=(ALL) NOPASSWD:/etc/init.d/hostapd start
www-data ALL=(ALL) NOPASSWD:/etc/init.d/hostapd stop
www-data ALL=(ALL) NOPASSWD:/etc/init.d/dnsmasq start
www-data ALL=(ALL) NOPASSWD:/etc/init.d/dnsmasq stop
www-data ALL=(ALL) NOPASSWD:/bin/cp /tmp/dhcpddata /etc/dnsmasq.conf
www-data ALL=(ALL) NOPASSWD:/sbin/shutdown -h now
www-data ALL=(ALL) NOPASSWD:/sbin/reboot
www-data ALL=(ALL) NOPASSWD:/sbin/ip link set wlan[0-9] down
www-data ALL=(ALL) NOPASSWD:/sbin/ip link set wlan[0-9] up
www-data ALL=(ALL) NOPASSWD:/sbin/ip -s a f label wlan[0-9]
www-data ALL=(ALL) NOPASSWD:/bin/cp /etc/raspap/networking/dhcpcd.conf /etc/dhcpcd.conf
www-data ALL=(ALL) NOPASSWD:/etc/raspap/hostapd/enablelog.sh
www-data ALL=(ALL) NOPASSWD:/etc/raspap/hostapd/disablelog.sh
www-data ALL=(ALL) NOPASSWD:/etc/raspap/hostapd/servicestart.sh

Once those modifications are done, git clone the files to /var/www/html. Note: for older versions of Raspbian (before Jessie, May 2016) use /var/www instead.

sudo rm -rf /var/www/html
sudo git clone https://github.com/billz/raspap-webgui /var/www/html

Move the high-res favicons to the web root.

sudo mv /var/www/html/app/icons/* /var/www/html

Set the files ownership to www-data user.

sudo chown -R www-data:www-data /var/www/html

Move the RaspAP configuration file to the correct location.

sudo mkdir /etc/raspap
sudo mv /var/www/html/raspap.php /etc/raspap/
sudo chown -R www-data:www-data /etc/raspap

Move the HostAPD logging and service control shell scripts to the correct location.

sudo mkdir /etc/raspap/hostapd
sudo mv /var/www/html/installers/*log.sh /etc/raspap/hostapd 
sudo mv /var/www/html/installers/service*.sh /etc/raspap/hostapd

Set ownership and permissions for logging and service control scripts.

sudo chown -c root:www-data /etc/raspap/hostapd/*.sh 
sudo chmod 750 /etc/raspap/hostapd/*.sh

Add the following lines to /etc/rc.local before exit 0.

echo 1 > /proc/sys/net/ipv4/ip_forward #RASPAP
iptables -t nat -A POSTROUTING -j MASQUERADE #RASPAP 
iptables -t nat -A POSTROUTING -s 192.168.50.0/24 ! -d 192.168.50.0/24 -j MASQUERADE #RASPAP

Force a reload of new settings in /etc/rc.local.

sudo systemctl restart rc-local.service
sudo systemctl daemon-reload

Unmask and enable the hostapd service.

sudo systemctl unmask hostapd.service
sudo systemctl enable hostapd.service

Move the raspap service to the correct location and enable it.

sudo mv /var/www/html/installers/raspap.service /lib/systemd/system
sudo systemctl enable raspap.service

Reboot and it should be up and running!

sudo reboot

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

Multilingual support

RaspAP uses GNU Gettext to manage multilingual messages. In order to use RaspAP with one of our supported translations, you must configure a corresponding language package on your RPi. To list languages currently installed on your system, use locale -a at the shell prompt. To generate new locales, run sudo dpkg-reconfigure locales and select any other desired locales. Details are provided on our wiki.

The following translations are currently maintained by the project:

  • Deutsch
  • Français
  • Italiano
  • Português
  • Svenska
  • Nederlands
  • 简体中文 (Chinese Simplified)
  • Indonesian
  • 한국어 (Korean)
  • 日本語 (Japanese)
  • Tiếng Việt (Vietnamese)
  • Čeština
  • Русский
  • Español
  • Finnish
  • Sinhala
  • Türkçe

If your language is not in the list above, why not contribute a translation? Contributors will receive credit as the original translators.

HTTPS support

The Quick Installer may be used to generate SSL certificates with mkcert. The installer automates the manual steps described in the wiki, including configuring lighttpd with SSL support.

Simply append the -c or --cert option to the Quick Installer, like so:

curl -sL https://install.raspap.com | bash -s -- --cert

Note: this only installs mkcert and generates an SSL certificate with the input you provide. It does not (re)install RaspAP.

More information on SSL certificates and HTTPS support is available on our wiki.

OpenVPN support

OpenVPN may be optionally installed by the Quick Installer. Once this is done, you can managage a client configuration and the openvpn-client service with RaspAP.

To configure an OpenVPN client, upload a valid .ovpn file and, optionally, specify your login credentials. RaspAP will store your client configuration and add firewall rules to forward traffic from OpenVPN's tun0 interface to your configured wireless interface.

Note: this feature is currently in beta. Please read this before reporting an issue.
