ntopng is the next generation version of the original ntop, a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntopng is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Windows as well. ntopng users can use a a web browser to navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. In the latter case, ntopng can be seen as a simple RMON-like agent with an embedded web interface.
