If you have a requirement to investigate and capture packets being transported across your campus network then the latest version of Wireshark could be what you’re looking for. Previously known as Ethereal this latest update has many improvements and additional features that are usually found on expensive commercial products.
Wireshark has been compiled as a Windows application but the available source code will easily compile on OS X, Linux & Solaris etc. Being an open source tool it is continuously being enhanced and developed, because of its ubiquitous nature, there are plenty of excellent books and manuals published as well as support and help which can be readily found from other academic users not to mention commercial consultants.
To download the free windows version visit the Wireshark website.
