How Packet Sniffing tools work
There are different types of packet sniffers. Some packet sniffers are used only for detecting hardware related problems. Other packet sniffing tools are actually some software apps that run on the host computers.
The packet sniffing tools intercept and log network traffic. The tools ‘view’ the network using wireless or wired network interface. The packet sniffing tool needs to have access to this interface on its host computer. If it is a wired network, a packet sniffing tool can capture the data which totally depends on the network’s structure.
The network structure might let the packet sniffer tool view traffic on the entire network or it can let it view only a small segment of it. If it’s a wireless network, packet sniffing tools can capture one channel using the wireless interface. If the host computer has multiple wireless interfaces, then the packet sniffer can capture multiple channels.
The sniffing tool then analyzes the captured raw packet data. The analysis is converted by the sniffing tool into a readable format. This analysis is nothing but the conversation between nodes on the network. This very information is helpful for the network technicians to locate the fault.
