Freeware tools and useful information

These are the latest tools for download. Theyíre all freeware and can be used without fear of retribution! In most cases (when possible), Iíve 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

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 itís 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.

Configuration and support docs

RADIUS server setup procedures
About: Written by Jimmy Ray Purser, an HP SA out of Chicago. This document contains step-by-step instructions for configuring a RADIUS server and a switch to support 802.1x authentication.  Itís the first REALLY useful paper Iíve 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. (JohnL@pgcgi.com)

Management tools

TFTPD32n tftp server
About: This is updated version of the TFTP software includes basic syslog, DHCP (very useful in lab testing when you donít want to mess with Win 2K) and an SNTP server. 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.

TERA TERM terminal emulation
About: This terminal emulation program works great. Itís 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 Ďem out.

Download and More info: Tera Term Pro v2.3

 

KIWI SYSLOG and other useful tools

Traffic generators/receivers

TFGEN traffic generator
About: A good traffic (unicast, multicast and broadcast)generator for testing.

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.

Packet capture tools

Wireshark protocol analyzer
About: Once Ethereal; now Wireshark. This is an open source network protocol analyzer for most platforms. 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.
