If you would like to surf the internet anonymously I’ll show you how to use Squid and Privoxy for this purpose. First we’ll configure Squid to filter some HTTP header fields. After this, web servers will most likely think that we aren’t requesting content through a proxy but rather directly with our browser. We will see that we can’t manipulate all HTTP header fields without running into problems: Privoxy will help us here.

Tuning and hardening Squid
January 26th, 2007 — Tech
Tuning and hardening Squid will be the topic of this post, where tuning means making it a little bit faster and hardening means less vulnerable to malicious use. The default installation of Squid on a Debian box has a lot of features enabled which most likely aren’t used: we want to turn these off. Then there might be situations where you probably want to use Squid but don’t want it to function as a cache: we’ll investigate this too.
Using a parent proxy with Squid

If you want Squid to be part of a hierarchy of proxies or you just want Squid to fetch content not directly from a web server but rather indirectly from another proxy then read on how to do that.
Transparent proxy with Squid

If you ever wanted to know how to setup a transparent proxy with Squid, because either you are just curious or you have more than one computer from which you want to surf the internet, and you don’t want to set the proxy manually, then this might be something for you.
I will assume that we have two networks: 172.16.0.0/24 and 172.16.1.0/24. These networks are connected to our router via eth1 and eth2 respectively, while the router itself has the IPs 172.16.0.1 and 172.16.1.1.
