Wireshark is a free and open source packet analyzer used for network troubleshooting and analysis. These days, home networks are becoming more and more complex, with a variety of devices connecting to the internet and each other. Monitoring your home network traffic can be a daunting task, but it doesn’t have to be. Wireshark can help you keep an eye on your home network and see what’s going on. In this article, we’ll show you how to use Wireshark to monitor your home network traffic.
The first thing you need to do is download and install Wireshark. You can get it for free from the Wireshark website. Once you have Wireshark installed, launch it and you should see a screen like this:
The top part of the Wireshark interface is the menu bar. The second part is the toolbar, which contains a variety of buttons that let you do things like start and stop captures, apply filters, and more. The third part is the packet list, which shows you a list of all the packets that Wireshark has captured. The fourth part is the packet details, which shows you more information about the currently-selected packet. And the fifth part is the packet bytes, which shows you the raw data of the currently-selected packet.
Now that you know your way around the Wireshark interface, it’s time to start capturing some packets. To do this, click the “Capture” menu and then select “Interfaces”. This will bring up a list of all the interfaces on your computer. Select the interface that you want to capture traffic on and then click the “Start” button. Wireshark will now start capturing all traffic on that interface.
Now that Wireshark is capturing traffic, take a look at the packet list. You should see a long list of packets scrolling by. If you want to see more information about a particular packet, just click on it and the packet details will appear in the packet details pane. To see the raw data of a packet, click on the “Packet Bytes” tab.
Wireshark comes with a powerful filtering system that lets you filter the packets that are displayed in the packet list. This can be very useful if you’re only interested in seeing certain types of traffic. For example, if you only want to see DNS traffic, you can apply a filter that only displays DNS packets. To apply a filter, click the “Capture” menu and then select “Display Filter”. This will bring up a list of all the available filters. Select the filter you want to apply and then click the “Apply” button. The filter will be applied and only the matching packets will be displayed in the packet list.
Wireshark is a powerful tool that can be used to monitor your home network traffic. By following the steps in this article, you can get started using Wireshark to see what’s going on your home network.
