Freeware tools and useful information These are the latest tools for download. They’re all freeware and can be used without fear of retribution! In most cases (when possible), I’ve included the link to the developer/distributor website to ensure that you download the latest version and get the most current support information. Hope these help. Also...If you come across a bad link or have something to add/update, please take a moment and send me a quick email.  Site Update History January 14, 2007 Link Update: The link to a Ethereal changed to WireShark. May 5, 2004 Link Update: The link to a TeraTerm download site was changed. The old one required a password for access. March 19, 2004 Link Update: The link to the RADIUS/802.1x configuration .pdf was incorrect. Study tools 9300 routing switch emulator About: This emulator approximates the operation of a 9300-series routing switch and, therefore, should be used only as a study tool. It defaults to the Foundry product name but it’s the same as the firmware for HP. The emulator is for an early version of the 07.x firmware; so, it may not be exactly like the most current version of firmware. And, like most emulators, it does not allow every available command...but it does a very good job. Important note: If you find that the emulator differs from the courseware, then always follow the courseware...because it provides the information that is fair-game on the exam.

This document contains step-by-step instructions for configuring a RADIUS server and a switch to support 802.1x authentication.  It’s the first REALLY useful paper I’ve come across on the subject. If you have not configured this before, you should try it out on a non-production server. By the way, if you have any related information on 802.1x, PLEASE email it to me so that I can include it here.

Note about the SNTP: On XP and Win2k, it may conflict with the native Windows Time Services. Optionally, you can disable these services within  Windows.

It’s an Open Source program and can be downloaded from many sites...do a Google search for more sites, if needed. BTW...this site has a lot of other great freeware and shareware tools. Check ‘em out.

Download from here: TFGEN MCAST multicast traffic receiver About: Use this multicast traffic reciever with TFGEN. Set TFGEN to send to a mutlicast address, i.e., 239.100.1.1 and a vaild port, i.e., 5000. Set Mcast to receive that traffic. A packet-capture will show the IGMP Joins and Leaves.

It allows you to examine data from a live network or from a capture file on disk. You can  interactively browse the capture data, viewing summary and detail information for each packet. Wireshark has several powerful features, including a rich  display filter language and the ability to view the reconstructed stream of a  TCP session.
