Etherscan Analyzer is an advanced network sniffer and protocol analyzer for Windows. With Etherscan, you can capture and analyze all packets over the local network. Etherscan decodes all major protocols, including Ethernet, NetBEUI, TCP/IP, and others. Packets are decoded down to the lowest layer with analysis of the most protocols and full access to raw data is provided. Etherscan Analyzer is capable of reconstructing TCP/IP sessions. With this feature, you can easily view data in their original format, for example, you will be able to read the actual text of an email - as well as any attachment - exactly as it was sent.
With Etherscan you are able to filter for specific traffic easily. Using these flexible, powerful filters during or after capture you can isolate traffic by specific node, protocol, error type and/or packet content. Also you can set aliases to IP or MAC addresses.
Etherscan Analyzer is a helpful tool for LAN administrators, security professionals, network programmers, or anyone who wants to have a full picture of the traffic going through one's PC or LAN segment. This application is designed for Internet users and small and medium-sized networks and can run on any Windows
