	Work In Progress

This section will document how to run your HDA as a network wide ad-blocking tool, utilising DNS redirects and a small pixel server.

Fedora 19

Precusors -

• You'll need net-tools installed to use ifconfig

yum install net-tools

• This guide assumes your network interface is named p2p1 and your HDA IP address is 192.168.1.2. Check with ifconfig, and change this guide where neccessary.

Get Ad List

nano /usr/local/bin/get-adlist.sh

#!/bin/sh
# Down the DNSmasq formatted ad block list
curl "http://pgl.yoyo.org/adservers/serverlist.php?hostformat=dnsmasq&showintro=0&mimetype=plaintext" | sed "s/127\.0\.0\.1/192.168.1.99/" > /etc/dnsmasq.adblock.conf
# Restart DNSmasq
/etc/init.d/dnsmasq restart

chmod -v 755 /usr/local/bin/get-ad-block-list.sh

Change DNSMasq config

echo "conf-file=/etc/dnsmasq.adblock.conf" >> /etc/dnsmasq.conf

Bind Apache to main IP address

• Edit the Apache config file using a file editor:

nano /etc/httpd/conf/httpd.conf

• Add your HDAs IP address to this section in the conf file:

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 192.168.1.2:80

• Restart Apache

service httpd restart

Pixel Server

• You need to download Pixelserv to the HDA:

wget http://proxytunnel.sourceforge.net/files/pixelserv.pl.txt 

• Move and rename the Pixelserv binary:

mv pixelserv.pl.txt /usr/local/bin/pixelserv

• Edit pixelserv using a file editing program of your choice

nano pixelserv

• Change the IP address to a free one of your choice (eg. 192.168.1.99)

$sock = new IO::Socket::INET (  LocalHost => '0.0.0.0',

change to

$sock = new IO::Socket::INET (  LocalHost => '192.168.1.99',

• Change permissions

chmod 755 /usr/local/pixelserv 

• Create file /etc/init.d/pixelserv

nano /etc/init.d/pixelserv

and copy the following to it (changing the IP addresses where neccessary):

#! /bin/sh
# /etc/init.d/pixelserv
#

# Carry out specific functions when asked to by the system
case "$1" in
   start)
     echo "Creating Interface "
     ifconfig p2p1:0 192.168.1.99
     echo "Starting pixelserv "
     /usr/local/bin/pixelserv &
     ;;
   stop)
     echo "Stopping script pixelserv"
     pkill -9 pixelserv &
     echo "Killing Interface "
     ifconfig p2p1:0 down
     ;;
   *)
     echo "Usage: /etc/init.d/pixelserv {start|stop}"
     exit 1
     ;;
esac
exit 0

• Change permissions

chmod 755 /etc/init.d/pixelserv

Enjoy ad-free network on ALL devices!
