Wireshark has many uses, including troubleshooting networks that have performance issues. After all, when using Wireshark on a networkĬonnection (or a flashlight in a cave), you’re effectively using a tool to hunt around tunnels and tubes to see what you can see.
Folks who use Wireshark on a network are kind of like those who use flashlights to see what cool things they can find.
Packet sniffing can be compared to spelunking – going inside a cave and hiking around. It also allows you to visualize entire conversations and network streams.įigure 1: Viewing a packet capture in Wireshark
Visualization: Wireshark, like any good packet sniffer, allows you to dive right into the very middle of a network packet. By applying a filter, you can obtain just the information you need to see. Filtering: Wireshark is capable of slicing and dicing all of this random live data using filters. Packet Capture: Wireshark listens to a network connection in real time and then grabs entire streams of traffic – quite possibly tens of thousands of packets at a time. Like any other packet sniffer, Wireshark does three things: Wireshark is the most often-used packet sniffer in the world. Packet is the name given to a discrete unit of data in a typical Ethernet network. Wireshark is a network protocol analyzer, or an application that captures packets from a network connection, such as from your computer to your home office or the internet.
