Packet visualization with Rumint
One of the tools recommended in Chris Sander’s Practical Packet Analysis book is called Rumint.
Rumint is a free, open source packet visualization tool available for Microsoft Windows (written in Visual Basic.)
Roomint’s author, Greg Conti, has a book to be published by No Starch Press called Security Data Visualization.
One problem I’ve run into with Rumint is that it doesn’t work on my setup. I run Windows XP and I’ve got WinPCap 4.0.1. It looks to me like a problem between Rumint and the latest version of WinPCap. The problem is that Rumint won’t show any network interfaces to sniff, so obviously things don’t work too well. 😉
