Now a days Network communication become an important part of every organization as well as part of every human beings.In a computer communication communicated data are in the form of data packets.Network packets in a computer communications can be defined as an amount of data in a limited size.In Internet all traffic travels in the form of packets, the entire file downloads, Web page retrievals, email, all these Internet communications always occur in the form of packets.Packet sniffer is a tool or device that can be used for capturing the packet at data link layer in a Network.Packet sniffer is not only a hackers tool but it can be used both by the hacker for eavesdropping and by the administrators for network monitoring and troubleshooting.Sometimes a packet sniffer is known as a network monitor or network analyzer.Many machine administrator or community administrator use it for tracking and troubleshooting community visitors.Packet sniffers are useful in wired as well as Wi-Fi networks for monitoring network.In this paper we studied the various methods for sniffing the data packets traveling across the Network in a LAN.Index term: Network packet sniffer,
