Network-wide Adblock on Ubuntu + OpenDNS adblocking

Based on the article found here: http://notes.ozmonet.com/index.php?title=Network-Wide_Adblock

This method will work for both Internet Explorer and Google Chrome.
You must have lighttpd or apache installed to serve up replacement images or pages.

Install squid: sudo apt-get install squid

Configure: /etc/squid/squid.conf

Install squidguard: sudo apt-get install squidguard

Download and configure adblock for use with squidguard

wget http://easylist.adblockplus.org/adblock_rick752.txt
create a sefile with this inside it:

/@@.*/d;
/^!.*/d;
/^\[.*\]$/d;
s#http://##g;
s,[.?=&/|],\\&,g;
s#*#.*#g;
s,\$.*$,, g;

Create the expression list: cat adblock_rick752.txt | sed -f sedfile > expressions

In your squidguard folder /var/lib/squidguard/db, create a folder for adblock and copy the expressions file inside it.

sudo chmod proxy.proxy -R adblock

Edit your /etc/squid/squid.conf, add this at the end

redirect_program /usr/bin/squidGuard -d -c /etc/squid/squidGuard.conf

Edit your /etc/squid/squidGuard.conf file

dbhome /var/lib/squidguard/db
logdir /var/log/squid

src my_network {
ip 192.168.219.0/24
}

dest adblock {
expressionlist adblock/expressions
redirect http://localhost/lol.jpg
}
acl {
my_network {
pass !adblock any
}
default {
pass none
redirect http://localhost/lol.jpg
}
}

Restart Squid and then configure your browsers to use the ip address of the server running squid, mine was http://192.168.219.111:3128, fire up your browser and surf ad riddled sites to test it.

Sign-up for OpenDNS, not only do they provide you with speedy DNS queries they also feature ad blocking. The good thing about OpenDNS is that you only have to configure your router and it enables all the features on every computer on your network.

Their DNS servers are down below:
208.67.222.222
208.67.220.220

If you need help configuring your computer or router please check their site.

Once you are done setting up your router login to their dashboard and go to settings \ Content Filtering. I enabled filtering for adware, parked domains and phishing.

Well that about covers it, enjoy add free surfing!
