"You can see Wikipedia---tcp/udp port list"2.5.4 option: Use external Network name Resolver This option and its approximate options are not available in earlier versions of Wireshark. In practice, I have not personally had the opportunity to experience the difference between this option or not, and I did not find the relevant description in the 1.10 version of my own user g

indicates that the server message is blue.A window similar to the one shown here is useful for reading protocol payloads, such as HTTP,SMTP,FTP.Change to hex dump mode to view the hexadecimal code of the payload, as shown in:When the pop-up window is closed, Wireshark only displays the selected TCP message stream. It is now easy to distinguish 3 handshake signals.Note: Here Wireshark automatically creates

Wireshark only displays the selected TCP packet stream. Now we can easily identify three handshakes. Note: Wireshark automatically creates a display filter for this TCP session. In this example: (IP. addr eq
