For more information on how to setup the SocketTest for UDP testing, see Section 7.1. The SocketTest in Figure 12-1 shows the two messages sent and received by the server. The length of the two messages is displayed in the terminal window. You can cross-reference the messages captured by Wireshark in Figure 12-2. First, the greetings message is sent. Then the two echo messages, with their received lengths, are sent by the client.
