The Info section indicates that the frame is an Echo request, the first step of a ping. In the third frame, the protocol changes to ICMP, the protocol that ping uses. #WIRESHARK CAPTURE INTERFACE NOT SHOWING MAC#In the Info column, you can see that the server answered and provided its MAC address. In the second packet, you can see that the source and destination addresses are also MAC addresses, but that no broadcast was needed. The sender wants that system to tell 192.168.1.22 its MAC address. In the Info column, you can see that the sender of the packet wanted to know who has an IP address of 192.168.1.110. In Figure 2-14, the first frame came from a MAC address that ended in 17:25:16 and was sent as a broadcast to every host on the network. Notice the Source and Destination columns. ARP is used to resolve IP addresses to MAC addresses. Each line in the upper frame of the window represents one packet. Notice the entries in the Protocol column the ARP and ICMP protocols are being used. Compare your capture to Figure 2-14 and note the following explanations. Figure 2-14 shows a typical capture of the preceding steps.When the ping is complete, immediately click the Capture menu in Wireshark and click Stop. Immediately click in the command prompt window and press Enter to begin the ping. The Capture Interfaces window closes and the Wireshark window opens. Click the Start button next to the interface with the most activity. You should perform the next few steps quickly so that you do not capture excess traffic. Arrange your desktop so that you can see both the command prompt window and the Wireshark Capture Interfaces window. Before you start to capture network traffic, open a command prompt and enter a ping to the IPv4 address of your partner’s system, but do not press Enter yet.If multiple interfaces are displayed, use the one that shows the most activity in the Packets column. Figure 2-13 shows the Capture Interfaces window, where only one interface has been detected. Click Interface List in the upper-left corner to display the interfaces detected by Wireshark. If this ping is not successful, you need to troubleshoot connectivity before continuing with the project. ![]() #WIRESHARK CAPTURE INTERFACE NOT SHOWING WINDOWS#Verify that you have connectivity by pinging the IPv4 address of Windows Server 2008 from Windows 7. On both systems, access a command prompt and enter ipconfig to verify the systems’ IP addresses. #WIRESHARK CAPTURE INTERFACE NOT SHOWING WINDOWS 7#
