install wifidog in linux

Pre-installation

This is where a lot of people run into problems, so let's state this in bold:
MAKE SURE EVERYTHING WORKS FIRST BEFORE INTRODUCING Wifidog INTO THE ENVIRONMENT
That especially means:

The router must boot properly
The router must bring up the interfaces properly
The router must set up the routes properly
The router must connect to the internet properly
DNS settings must be set or obtained properly. DNS must work.
DHCP settings (client, server or both) must be set or obtained properly.
The ipt_mac.o kernel module must be loaded.
If using NAT, the router must setup NAT/masquerading rules with iptables properly
Clients on the desired (WIFI) network must be able to bind, associate, lease and connect the internet properly
All the above must happen automatically when the router starts or gets rebooted

Do NOT proceed with installing Wifidog until you've satisfied the above. It will not work otherwise and you will waste lots of time.

Installation

Wifidog, like many open source projects, is distributed with standard autotools utilities to make installation easy. Unpack the tarball (from Sourceforge) or get the lastest source from SVN (see Download menu), then follow the standard:

./autogen.sh
make
make install

If you do not install it with make install, then you will find the compiled wifidog gateway binary in src/wifidog (also don't forget to copy wifidog.conf to /etc).

OpenWrt? ipkg

mkdir ~/wifidog.openwrt
cd ~/wifidog.openwrt
wget http://downloads.openwrt.org/whiterussian/newest/OpenWrt-SDK-Linux-i686-1.tar.bz2
tar -jxvf OpenWrt-SDK-Linux-i686-1.tar.bz2
svn checkout https://dev.wifidog.org/svn/trunk/wifidog
cd wifidog
./autogen.sh
make ipk OPENWRTSDK=~/wifidog.openwrt/OpenWrt-SDK-Linux-i686-1

If there were no errors, your package should be in ~/wifidog.openwrt/OpenWrt-SDK-Linux-i686-1/bin/packages

Configuration

Edit /etc/wifidog.conf and follow the instructions in the file. Things should be self-explanatory.

Running Wifidog for the first time

Run Wifidog with the following switches:

wifidog -f -d 7
  -f means to run in foreground (do not become a background daemon)
  -d 7 increases debug output level to the maximum

Testing

As a client on the WiFi network (or whatever interface is configured as the LAN interface in /etc/wifidog.conf), open a web browser and try to browse to your favourite web site.

Monitor the output of the running Wifidog to see what it's doing.
