Squid Proxy Server

• Squid is a Unix-based proxy server that caches
  Internet content closer to a requester than its
  original point of origin. Squid supports caching
  of many different kinds of Web objects, including
  those accessed through HTTP and FTP. Caching
  frequently requested Web pages, media files and
  other content accelerates response time and
  reduces bandwidth congestion.

Reasons to Include proxy servers on your Network

• To share internet connection on a LAN
• To speed up internet surfing
• To hide the IP address of the client computer
  for anonymous surfing
• To implement internet access control
• To scan outbound content
• To circumvent regional restrictions

Installation

• The first thing we want to do is to update apt.
  From your terminal window, issue the command sudo
  apt-get update. Once that completes, you could
  also run an upgrade with the command sudo apt-get
  upgrade. Of course, should this upgrade the
  kernel, you'll want to do a reboot, so schedule
  this accordingly.
• Once the update/upgrade is complete, install
  Squid with the command
• sudo apt-get install squid3
• The installation will pick up the necessary
  dependencies (libecap3, libltdl7, squid-purge,
  and squid-langpack) and complete without issue.

Configuration

• The configuration of the Squid Proxy Server is
  handled in the /etc/squid/squid.conf. I will show
  you how to configure a very basic proxy server.
  The first thing we need to do is uncomment the
  line (by removing the character)
• http_access allow localnet
• To find that line, issue the command
• sudo grep -n http_access /etc/squid/squid.conf
