If you are looking for a comprehensive guide to help you unleash the powers of Wireshark, you've come to the right place. Wireshark is the best open-source network analyzer available. It is packed with features comparable to commercial network analyzers, and with a large, diverse collection of authors, new enhancements are continually developed. Wireshark is a stable and useful component for all network toolkits, and new features and bug fixes are always being developed. A lot of progress has been made since the early days of Wireshark (when it was still called Ethereal); the application now performs comparably to (and in some regards better than) commercial sniffing software.Use Wireshark in Your Existing Network Architecture
