Squid: Blocking Unwanted Sites

Table of Contents

Introduction

There are many reasons to block access to some sites. I will not enumerate the reasons here. Here follows the procedure that I have used for blocking access to some "annoying" advertising sites that turn my webalizer statistic to dust, beeing always in the Top 30 stats.

The blocking sites file

First you have to build a file where you must put the addresses you want to be blocked. Let's create one in the default location for squid configuration files, /usr/local/squid/etc/, and name it blockedAds: 

# touch /usr/local/squid/etc/blockedAds
and populate the file, using the editor of your choice, similar with this example: 
.stupidAds.com
.annoyingAds.com
.intrusiveAds.org
In this way you will block the whole domains specified there. Next we have to tell to the Squid Web Proxy Cache to use that file.

Configure Squid to use the blocking sites file

Edit the squid's configuration file, /usr/local/squid/etc/squid.conf, and insert the following in the http_access section: 

acl blockedAds url_regex "/usr/local/squid/etc/blockedAds"
http_access deny blockedAds
Now you have to restart squid (stop and start).
