Resources for “Securing WLANs with WPA and FreeRADIUS, Part I”
Dumbill, Edd, Brian Jepson, and Roger Weeks. Linux Unwired. Sebastopol, CA: O'Reilly & Associates, 2004. This book includes one of the more concise and clear explanations of WPA I've seen, plus detailed instructions on creating end-to-end-Linux WPA solutions.
Gast, Matthew. “A Technical Comparison of TTLS and PEAP.” www.oreillynet.com/pub/a/wireless/2002/10/17/peap.html?page=last&x-maxdepth=0 . This on-line article spells out the most important differences among EAP-TLS, PEAP and EAP-TTLS.
Malinen, Jouni. hostap.epitest.fi. Home page for wpa_supplicant, a WPA supplicant for Linux; hostap, a driver for Linux-based APs using Prism WLAN hardware; and hostapd, a WPA-enabled access point daemon package. Besides this essential software, Jouni also provides much useful documentation.
Strand, Lars. “802.1X Port-Based Authentication HOWTO.” www.tldp.org/HOWTO/html_single/8021X-HOWTO. A concise but narrow-scoped guide to setting up WPA with Xsupplicant, Cisco WLAN access points and FreeRADIUS to use 802.1x authentication. As of this writing, Xsupplicant supports only 802.1x authentication, not TKIP encryption.
www.freeradius.org is the home page for the FreeRADIUS project, where you can download the latest FreeRADIUS software and documentation.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.
