My notes: Simple configuration and easy to comprehend. The filtering features via GUI is very helpful... we can even filter traffic by application. Ethereal is known as the mother of all sniffers .... i liked the GUI of Analyser 3.0 very simple and better than ethereal.
Analyzer 3.0 notes on its website
Analyzer is a packets capture tool; it captures packets from network and it displays them through a graphical interface. The user can choose the network adapter (used for the capturing and monitoring process), specify an appropriate filter, select, copy and paste packets. Advanced features concern both the possibility to make (and plot) some advanced statistics on the captures packets and to plot statistics in real time (number of packets flowing through the network and so on).
