Ad-blocking

	Work In Progress
	This article is currently undergoing major expansion or restructuring. You are welcome to assist by editing it as well. If this article has not been edited in several days, please remove this template.

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
# Download 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
service dnsmasq restart

chmod -v 755 /usr/local/bin/get-adlist.sh

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

Change DNSMasq config

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

service dnsmasq restart

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!
