Minotaur is a simple layer 2 traceroute program written in PHP. The script is desgined to work with almost all kinds of Cisco switches with CDP (Cisco Discovery Protocol) turned on and TACACS+ login turned on. The script will take an IP or MAC address you are looking for and traverse through the switch network. There is an option for a seed device as well.

Update: Works now with PHP 4.2+ (register_globals on/off). Validation of form updated (security fix). PHP-Trace is a traceroute script that performs a tracert from your webserver to a target that you can enter via a form.

Designed to use with MTR (http://www.bitwizard.nl/mtr/) as a traceroute/ping program, this application allows you to add sites and places from where you can traceroute and store the info into a database. You can look at different traceroutes from one site on one screen, and print them. You can also set the order on screen, etc. Requires PHP and MySQL. Includes a little perl-script to import logfiles that are generated by MTR. Also, more reliable, faster and offers more detailed statistics. Update: php-version check.
