Introduction

As a network administrator, monitoring network traffic is crucial to ensure the smooth operation of your network. ntop is a powerful network traffic probe that provides real-time network usage information, similar to the popular top Unix command. In this article, we will explore the features and benefits of ntop for Win32, a platform that allows ntop to run on Windows operating systems.

What is ntop?

ntop is a network traffic probe that uses libpcap, a popular packet capture library, to collect and analyze network traffic data. It has been written in a portable way, allowing it to run on various Unix platforms and Win32 as well. ntop acts as a web server, providing a web interface for users to navigate through network traffic information.

Key Features of ntop

Web Interface

ntop's web interface is one of its most significant features. Users can access ntop using a web browser, such as Netscape, to view real-time network traffic information. This interface provides a user-friendly way to monitor network usage, making it easy to identify potential issues.

Limited Configuration and Administration

ntop's web interface also allows for limited configuration and administration. Users can access various settings and options, such as network interface configuration, traffic filtering, and data export, all from within the web interface.
