As seen in the previous example, you can filter the ports with:.You can also filter the source or destination IP addresses with:.Filter the IP address (to analyze only one device on your network):.Reading these filters is quite intuitive, but instead of trying random formulas, here are some of the most useful ones: It’s exactly what you think, it will display only the packets using the port 80 (HTTP traffic in general). That’s why Wireshark includes a field near the top of the screen, where you can enter a formula to only show the packets that are potentially interesting for you (or exclude them). Devices talk quite a lot on our networks, and it might be overwhelming to see all of these packets.

Learn how the good and the bad guys hack! So, I won’t give you more details here, but you can check the official documentation to learn more about it. Packet analysis with Wireshark could be a dedicated article, or even a full book on its own. I’ll show you how to filter this list in the next section. For example, if you are looking for suspect HTTP activity from a specific IP address, you can skip everything unrelated (like DNS requests and other IP addresses). It will help you to select the ones you are interested in. On the first part, you’ll see the macro information, like source, destination and protocol. Packet bytes: the exact packet content, with bytes and hexadecimal format (less useful for us ^^).Packet details: when you select one packet, you can see its content, in a more or less readable text format. Where you can see all captured packets, and use the display filters to only show those that interest you. Packets analysisĪfter doing a capture of the network traffic, you can then analyze its content. It will keep capturing the network traffic until you press the stop button (the red one in the top bar).
