Machine Learning. WPA2 Enterprise on Ubuntu: Configuring an 802.1x FreeRADIUS Server. This howto describes setting up the FreeRADIUS serverv2.1.10 on Ubuntu Maverick v10.10 including properly signed certificates for server identification.
The setup is known to work for clients running Windows 7, Ubuntu, Android, iPhone etc. Background: It has been known for many years that Wired Equivalent Privacy (WEP) encryption is broken. Pre-shared WEP keys can be cracked in a matter of minutes. Its replacement, Wi-Fi Protected Access II (WPA2) is now shipped on most consumer devices. While WPA2 Personal may be suitable for home-use, it is often not emphasised that knowing the pre-shared keys (PSK) enables all wireless traffic to be decrypted.
This point should be stressed more since it occurs quite frequently. I recently upgraded the wireless network for an organisation with a large number of untrusted users that share the same Internet connection. Currently the only practical solution for this network of untrusted users is WPA2 Enterprise. Prerequisites: FreeRADIUS Installation:

You should be warned that although I've tried my best to make a straight-forward guide, if you are only beginning with the EJBCA deployment, make sure you've at least ran through several set-ups following the Quick Start Guide for Ubuntu (should work for Debian Squeeze as well). The entire installation below takes on a more serious deployment schema, and you might find yourself a little overwhelmed if this is your first time starting-out. There are plans to write some troubleshooting guidelines related to installation described below, but it's currently not the first thing on the TODO list, unfortunately.
Software Requirements For the purpose of running the EJBCA as certification authority, several software requirements need to be met. The version of JBoss AS used in this guide is 5.1.0.GA. ? Installing Required Java Packages ? ? ? Setting-up MySQL Server ? ? ? Setting-up System Accounts ? Joomla! The CMS Trusted By Millions for their Websites. Customising the way modules are displayed. This document explains different ways of customising your template to change the way modules are displayed.
Counting modules in a given module position The countModules method can be used within a template to determine the number of modules enabled in a given module position. This is commonly used to include HTML around modules in a certain position only if at least one module is enabled for that position. This prevents empty regions from being defined in the template output and is a technique sometimes referred to as “collapsing columns”. For example, the following code includes modules in the 'user1' position only if at least one module is enabled for that position. <? The countModules method can be used to determine the number of Modules in more than one Module position. The argument to the countModules function is normally just the name of a single Module position.
$this->countModules( 'user1 + user2' ); $this->countModules( 'user1 and user2' ); $this->countModules( 'user1' and 'user2' );
