![]() Press the shark symbol with the word Start. Options lets you change the network interface. The Packet Bytes Pane: This shows a canonical hex dump of the packet data. The Packet Details Pane: This is the gray area that shows the protocol fields of the packet. The Packet List: This shows all packets that are captured and is shown in blue in the preceding image. The Filter Toolbar: This has a filter pane when you type in the protocol that you want to view. The Menu: This is broken into the following 11 headings:įile, Edit, View, Go, Capture, Analyze, Statistics, Telephony, Wireless, Tools, Help. The view above shows The Main Window, which is broken into different sections: If you need to change the interface, go to Capture and select Options. When your Wireshark console appears, it should look similar to that shown below. You will now see a Wireshark shortcut on the desktop, the same as below:ĭouble-click it and choose your network interface. ![]() The wizard will appear to say the installation is complete. It should take roughly another 2-3 minutes. The Wireshark installation will still be running in the background. The following wizard will appear (see below). The installation will commence, and the pop-up box below will appear.Īccept the license agreement and press I Agree.Īccept the default settings by pressing Next. Keep pressing ‘Next’ and accept the defaults. ![]() This will bring up the installation wizard. You want to download the Windows Installer (64 bit).Ĭlick on the link for your version of software, and you will see a pop-up box at the foot of your screen.Ĭhoose run, and when the UAC prompt appears, choose Yes. The output will look similar to the following: You must ensure that you use the full URL. Go to to visit the Wireshark download page. In this practical exercise, you are going to install Wireshark on a Windows 10 computer, and then capture a packet. cap.Practical Exercise – Capturing a Packet Using Wireshark Save the captured data by selecting 'File -> Save As.'.When you have finished the capture, press 'Stop'.Now a smaller window opens showing the number of packets received. From the menu in Wireshark select 'Capture -> Options.', and in the field 'Interface' select your network card.Connect the hub between the AlphaCom and the IP network.So to capture the data a HUB or a managed switch must be used, an unmanaged switch cannot be used. Managed switches - These switches have one or more methods to modify the operation of the switch.This type of switches are not suitable for network analysis. They are typically the least expensive switches, found in home, SOHO, or small businesses. Unmanaged switches - These switches have no configuration interface or options.The availability of low-priced network switches has largely rendered hubs obsolete but they are still seen in older installations and more specialized applications. Hubs do not manage any of the traffic that comes through them, and any packet entering any port is regenerated and broadcast out on all other ports. HUB - A network hub is a fairly unsophisticated broadcast device. ![]() However, these cost much more than a hub or an unmanaged switch. ![]() Managed switches can be configured to allow one port to listen in on traffic from another ports. Connecting the protocol analyzer to a hub allows it to see all the traffic on the segment. Ī protocol analyzer connected to a switch does not always receive all the desired packets since the switch separates the ports into different segments. Wireshark is freeware and can be downloaded from. As data streams flow across the network, the sniffer captures each packet and eventually decodes and analyzes its content according. Wireshark (formerly known as Ethereal) is a packet analyzer (also known as Ethernet sniffer) that can intercept and log traffic passing over the ethernet port. In order to capture data you need the following equipment: This article describes how to use the PC program Wireshark to capture data from the ethernet port of the AlphaCom. Sometimes it is useful for debugging purposes to analyze the data on the IP network. ![]()
