For system administrators, network engineers, and security analysts, it is essential to keep a track of network traffic. At some point it will be necessary to read the network traffic directly instead of monitoring application level details. Network security audits, debug network configurations, and usage patterns analyzing can all require network traffic monitoring. This task can be achieved by using network monitoring software, or network sniffers, that sniff the traffic and display it on your computer on the network.
