Simply Wireshark

It could be used for the following; analysis of network problems, detection of intrusion and misuse by internal and external forces, screening of bandwidth utilization, running statistical analysis on data in motion, debugging client/server communications, spying on other networks, and identifying data traffic on a network that is requested by a user.
