Database/Map/Server

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
sudo apt-get install hostapd
sudo apt-get install dnsmasq

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

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

1. 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

1. restart dnsmasq

sudo /etc/init.d/dnsmasq restart

1. 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

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

some popup mehods

place javascript files and map tiles into /var/www/html

MQ var directory archive

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

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