Packet sniffer is a tool which captures all the packets on the network irrespective of the final destination of the packet. Packet Sniffer could be used to monitor the bottlenecks in the network, alarm the irregular behavior in the network, capture passwords and VoIP from any system in that network. This paper gives a brief introduction of what is a packet sniffer, its structure and what is its working. Then key features of top packet sniffing tools (i.e. Wireshark, TCPdump and Colasoft Capsa) are discussed. Further, the above tools are compared on the basis of characteristic behavior and quantitative parameters. Finally, one gets the best tool amongst these three in a particular situation.
