Before you can do anything, you need to configure the Wifi on the Pi (NB: default Pi login is 'pi' and default password is 'raspberry')

The setting up a headless Pi instructions here (in particular Step 3) worked for us, although we only needed ssid and psk (password) for the network={... step.

Lets set up our map server with local cached image files

Installing required software

Install nginx (server), hostapd (wifi AP host), dnsmasq (light dns server) install Nginx 

sudo apt-get update
sudo apt-get install nginx -y
sudo apt-get install hostapd -y
sudo apt-get install dnsmasq -y

Web Server

Set up web server to forward 404's to root directory (needed for captive portal behaviour) and start edit /etc/nginx/sites-available/default

and modify line in "location / {" section: 

try_files $uri $uri/ = 404;

becomes 

try_files $uri $uri/ /index.html;

Now start the server 

sudo service nginx start

Set up hostapd

Set up AP with hostap (instructions from set up AP with udhcpd) edit the file /etc/hostapd/hostapd.conf 

interface=wlan0
ssid=TacticalSpaceLab
hw_mode=g
channel=6
auth_algs=1
wmm_enabled=0

Edit the file /etc/default/hostapd and change the line: 

#DAEMON_CONF=""

to 

DAEMON_CONF="/etc/hostapd/hostapd.conf"

Start it up, and add it to start at boot 

sudo service hostapd start
sudo update-rc.d hostapd enable

Note for EDIMAX adaptors

edimax version of hostapd if using an edimax wifi usb 

wget http://www.daveconroy.com/wp3/wp-content/uploads/2013/07/hostapd.zip
unzip hostapd.zip 
sudo mv /usr/sbin/hostapd /usr/sbin/hostapd.bak
sudo mv hostapd /usr/sbin/hostapd.edimax 
sudo ln -sf /usr/sbin/hostapd.edimax /usr/sbin/hostapd 
sudo chown root.root /usr/sbin/hostapd 
sudo chmod 755 /usr/sbin/hostapd

DHCP and DNS for access point and captive portal

Set up /etc/network/interfaces for serving DHCP and DNS 

auto lo 
iface lo inet loopback 

auto wlan0
iface wlan0 inet static
  address 10.1.2.1
  netmask 255.255.255.0
  network 10.1.2.0

configure dnsmasq /etc/dnsmasq.conf 

# captive portal to this
no-resolv 
server=/localnet/10.1.2.1
server=/tacticalspace/10.1.2.1
address=/#/10.1.2.1
interface=wlan0
dhcp-range=10.1.2.5,10.1.2.200,12h

restart dnsmasq 

sudo /etc/init.d/dnsmasq restart

More Captive Portal Stuff

Forward all IP to the device

Turn on ip forwarding for IPV4 

sudo nano /etc/sysctl.conf

uncomment: 

net.ipv4.ip_forward = 1

then run the following to set up IP forwarding from iptables conversation for captive portals 

sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 10.1.2.1:80 
sudo iptables -t nat -A POSTROUTING -j MASQUERADE

Some notes about the process of making a captive portal

Pop up page info for IOS, Windows, and Android

forward to domain


some popup mehods

Logging people

if you want dnsmarsq script logging... Create /var/log/dhcp_leases file with write create /usr/bin/logdhcp, make executable add it to dnsmasq config 

#!/bin/bash
destfile=/var/log/dhcp_leases
#if [ "$1" == "add" ]
#then
  if [ -f "$destfile" ]
  then
    echo "$1 $2" >> "$destfile"
  fi
#fi
Logging dhcp.png

ended up using dnsmasq for DNS and DHCP. Setting DNS forward IP to local for captive portal setup

Map framework

Copy the server framework files across

The files needed for hosting the map are part of the Open Maps GitHub repository in location "Device Files/www/" Place these file (javascript, example index, map tiles) into /var/www/html

The repository only includes very far-out zoom levels (2,3,4). This older archive has zoom levels down to 18 in the areas around central Paris, Berlin, and Vienna: MQ var directory archive

Remember to make all /var/www/html folders readable with: 

sudo find /var/www -type d -exec chmod a+x {} +
sudo find /var/www -type d -exec chmod a+w {} +
sudo find /var/www -type d -exec chown root:root {} +
sudo find /var/www -type f -exec chmod a+r {} +
sudo find /var/www -type f -exec chown root:root {} +

Power saving

If you are using the device for battery-based or power-sensitive installs, follow these instructions for disabling LED and HDMI functionality to save power.


For Map content

MapNik coding platform for maps... pull render tiles using this?

beautiful Stamen Design map that can be used

Map example1.png
Map example2.png

Everything Script

Run these individually first 

sudo -i
apt-get update </dev/null
apt-get -y install nginx hostapd dnsmasq < "/dev/null"

then 

sed -i 's/try_files $uri $uri\/ =404;/try_files $uri $uri\/ \/index.html;/g' /etc/nginx/sites-available/default
service nginx start
