How do Packet Sniffers work? Every network has various components like workstations and servers, which are called nodes in networking terminology. The data is transferred in the form of packets between these nodes. Every packet has actual data and control information. This control information helps the packet to reach the destination for the source. This control information includes various details like IP addresses of sender and receiver, packet sequencing information, etc. When the data packets are transmitted through the network, they pass through several nodes in the network. These packet’s control information will get checked by each network adapter and the connected device. It is checked for the node it is headed toward. For the normal circumstances, the packet gets ignored if it is addressed for another node. Packet sniffing programs make some nodes to collect all or a defined sample of packets regardless of their destination address. Packet Sniffers analyze the network by...
