#SCREENSHOT WIRESHARK PACKET CAPTURE HOW TO#

After you captured the data, click Capture > Stop to stop the network trace. (Screenshots property of Wireshark 2021 Wireshark) Click Launch to start the capture. Once again, the thickness of the links represent the amount of data that was transferred to/from each port. In the toolbar, click the Capture icon and select the interfaces. Please answer the questions below based on the snapshot.

It appears that there might be an ongoing network attack. How to do it From the Statistics menu, choose Capture File Properties: What you will get is the Capture File Properties window (displayed in the following screenshot). Question: Above is a snapshot of Wireshark packet capturing. Q2.2 What is the IP address and service of. In the screenshot we see that almost all servers were listening on port 443 (HTTPS), except one - 8.8.8.8 was listening on port 53 (DNS). Please justify your answer based on information given in the snapshot. On the added line, write there a name of the filter (for example MikroTik sniffing) and set udp port 37008 as the filter. You should be able to use Wireshark to drill into the sFlow packets. Select the products and versions this article pertains too. This will show to read a sflow data in packet capture. Click on + button to add a new line to the list. This article provides steps about how to break down an sFlow packet in Wireshark. It will open a new window with capture filters. In addition, on the right hand side we see the port numbers which those servers were listening on. In Wireshark menu, click on capture and then select capture filters. For example, the link connecting 192.168.1.107 to 52.85.219.239 is much thicker than the link with 8.8.8.8, representing the fact that in this packet capture much more data was transferred to the former IP address than to the latter one.

The nodes are connected to each other by links which vary in thickness depending on the amount of bytes transferred between the two IP addresses. Wait a bit more than one minute (we’ll see why shortly), and then begin Wireshark packet capture. On the left, you can see an internal IP address (192.168.1.107) made a number of connections to public servers represented by multi-colored nodes in the middle of the diagram.

As can be seen in the above screenshot, the Sankey diagram makes it easy to see what’s happening in the packet capture at a glance. This module uses a Sankey Diagram to help you visualize the top 50 connections (more than 50 becomes difficult to read).
