How to Spy on Your "Buddy's" Network Traffic: An Intro to Wireshark and the OSI Model. Wouldn't it be nice to just sit at your buddy's house, plug into his network, and see exactly what he's doing? What if it was as easy as that? What makes packet sniffers like Wireshark such potent tools is that a majority of local area networks (LANs) are based on the shared Ethernet notion.
In a shared Ethernet, you can think of all of the computers in a LAN as being plugged into the same wire, and all of the traffic that travels through it can be captured. Packet sniffers are more formally known as network analyzers and protocol analyzers. Everything. For example, assume that your network card picks up a packet from someone else's network. Now, this is an oversimplified version of what really goes on, but I'm trying to illustrate a point. Before we get into grabbing frames and causing mayhem for lulz, we need to explain what a packet is and the concept of a frame.
The Open Source Interconnection (OSI) Model The model is divided into seven layers, as shown below. Layer 1: Physical $ .
