Here’s an overview of the steps to install the SquidGuard web filter plugin for Squid 3.x on Debian or Ubuntu Linux:
- Install SquidGuard and its dependencies:
sudo apt-get update
sudo apt-get install squid3 squidguard
- Create the SquidGuard configuration directory:
sudo mkdir /etc/squidguard
sudo chown proxy:proxy /etc/squidguard
- Download the blacklists:
You can download pre-configured blacklists from the internet or create your own. The blacklists contain the URLs of websites that you want to block.
- Convert the blacklists to the SquidGuard format:
sudo squidGuard -C all
- Edit the Squid configuration file:
sudo nano /etc/squid3/squid.conf
Add the following lines at the end of the file:
url_rewrite_program /usr/bin/squidGuard
url_rewrite_children 5
- Restart Squid:
sudo service squid3 restart
After completing these steps, the SquidGuard web filter plugin should be installed and configured. You can verify its functionality by attempting to access a website that is listed in the blacklists. The website should be blocked, and you should receive an error message.
