Today we are seeing that computer networks are increasing in their sizes very rapidly. Number of its user increased in past few years and traffic flows in networks also increased, so it’s very important to monitor networks traffic as well as its user’s activities to keep the network smooth and efficient. For complex network it’s very tough task to maintain and monitor the network, because large amount of data available. For this purpose packet sniffing is used. Packet sniffing is important in network monitoring to watch network activities which help network administrators to find out problems. This paper focuses on packet sniffer working in different environments, Behavior of already existing sniffer; their problems and challenges while performing sniffing. For accomplish of monitoring task, a tool is developed which will remove deficiency of existing tool. By using this packet sniffer we can capture traffic as well as we analyzed capture traffic. We can generate reports on the basis of analyzed traffic. Many protocol like TCP, IP, UDP etc. are implemented and filtering on basis of protocol is also done. Alerts generated on the occurring of suspected activities.
