Squid Configuration. Squid Configuration. SquidFaq/ReverseProxy. What is the Reverse Proxy (httpd-accelerator) mode?
Occasionally people have trouble understanding accelerators and proxy caches, usually resulting from mixed up interpretations of "incoming" and "outgoing" data. I think in terms of requests (i.e., an outgoing request is from the local site out to the big bad Internet). The data received in reply is incoming, of course.
Others think in the opposite sense of "a request for incoming data". An accelerator caches incoming requests for outgoing data (i.e., that which you publish to the world). Quite apart from taking the load of a site's normal web server, accelerators can also sit outside firewalls or other network bottlenecks and talk to HTTP servers inside, reducing traffic across the bottleneck and simplifying the configuration. The Squid redirector can make one accelerator act as a single front-end for multiple servers. In such a configuration, the web administrator renames all non-cachable URLs to the httpd's port (81). Common Problems.
Access Control and Access Control Operators - Squid User's Guide. Access control lists (acls) are often the most difficult part of the configuration of a Squid cache: the layout and concept is not immediately obvious to most people.
Hang on to your hat! Unless the Squid Configuration Basics chapter is still fresh in your mind, you may wish to skip back and review the access control section of that chapter before you continue. This chapter assumes that you understood the difference between an acl and an acl-operator. The primary use of the acl system is to implement simple access control: to stop other people using your cache infrastructure. (There are other uses of acls, described later in this chapter; in the meantime we are going to discuss only the access control function of acls.)
There are two elements to access control: classes and operators. Let's work through the below example line-by-line. If the admin connects to the cache from the PC, Squid does the following: Squid Configuration. Seven Different Linux/BSD Firewalls Reviewed. Did you know more than 500 million computers in the United States have been disposed of in the last 10 years?
That’s approximately 2 computers per person! One of the best ways to re-purpose an old computer is to install a Linux or FreeBSD firewall distribution, and use it to run your personal, home office, or small office network is one way to keep “obsolete” technology from ever reaching a landfill. Help the environment by reusing an old computer as a firewall.
It will protect your computer from internet worms, save you time, money and most importantly – improve your internet experience as a whole. Fact: A wireless router at an electronics store that can cost in excess of $100 is actually slower than any computer made in the last decade. By today’s standards, the 500MHz computer that’s been running quietly in my closet for the past 3 years is beyond obsolete. Squid + SquidGuard. Voici un petit document qui décrit l’installation de Squid avec le plugin SquidGuard sur une distribution linux Debian. SQUID est un proxy WEB puissant avec de très nombreuses options. SquidGuard est un plugin qui permet de rediriger certaines pages selon des critères (mot dans l’url etc..) vers une pages choisie, ceci afin d’en interdire la consultation.

BackTrack Linux - Penetration Testing Distribution. Quels outils pour auditer la sécurtié de son réseau. Outils d'Audit de Securité de Réseau et Scanner de Vulnerabilité. Wall. m0n0wall is a project aimed at creating a complete, embedded firewall software package that, when used together with an embedded PC, provides all the important features of commercial firewall boxes (including ease of use) at a fraction of the price (free software). m0n0wall is based on a bare-bones version of FreeBSD, along with a web server, PHP and a few other utilities.
The entire system configuration is stored in one single XML text file to keep things transparent. m0n0wall is probably the first UNIX system that has its boot-time configuration done with PHP, rather than the usual shell scripts, and that has the entire system configuration stored in XML format. In m0n0wall 1.8.1, the base system has been switched to FreeBSD 8.4 for better support of recent hardware, and there have been significant improvements, new features and bug fixes in many areas.
