re: 10 Free Network Analysis Tools
www.networktimeout.com is a free online packet analysis service that uses the protocol parser included in ExtraHop's real-time product. This service analyzes packet dumps and teases out critical metrics for HTTP, CIFS, Citrix ICA, all major databases, TCP, and more. It's like having network engineers pouring over your packet dump with Wireshark for 10 hours ... but in a minute.
