Capturing the Data Packet by Setting the NIC Card in Promiscuous Mode

Packet Sniffer is computer software. That can capture the data packets from the network. Whatever the data is capturing that will be decoded. the decoding or capturing the data can be done by using network interfacing controller in promiscuous mode. It also discusses ways to detect the presence of such software on the network and to handle them in an efficient way. Packet sniffer can able to capture the data of entire network that either wired network or wireless network. This paper presents practical results of capturing the data packet by setting the NIC card and results are verified.
