ntopng

This post is obsolete, please read Saying Goodbye to Hierarchical Clusters in ntopng. As you know via ZMQ you can use ntopng as collector for nProbe instances. You can decide to merge all probes into one single ntopng interface (i.e. all the traffic will be merged and mixed) or to have an interface per probe. Example: Start the remote nProbe instances as follows [host1] nprobe --zmq "tcp://*:5556" -i ethX [host2] nprobe --zmq "tcp://*:5556" -i ethX [host3] nprobe --zmq "tcp://*:5556" -i ethX [host4] nprobe --zmq "tcp://*:5556" -i ethX If you want to merge all nProbe …

The ntopng architecture is divided in three layers: Ingress layer (flow or packet capture). Monitoring engine: the ntopng core. Lua scripting engine Data export layer (via web, syslog or log files). Thanks to the scripting engine, ntopng is fully scriptable. This means that via Lua you can extract the monitoring information and report it into HTML pages or export it to third party applications. The ntopng Lua API is pretty simple it consists of two classes, ntop and interface. ntopng also comes with some example scripts that highlight the main …

This is to announce the release of ntopng 1.1. The main changes with respect to 1.0 include: Enhanced web GUI with new menus and extension of previous sections. Ability to specify multiple interfaces simulatenously (just repeat -i). Performance improvements both in nDPI and the ntopng engine (yes multi-Gbit traffic analysis is possible). Several enhancements to the flow collection interface (note that you need the very latest nProbe) that is not much faster and written in native C++ code. Added Google Maps support and HTML 5 map geolocation support. Ability to save …

Last Saturday 26th of October, we have presented a tutorial on ntopng at the Italian LinuxDay 2013. The slides we used for this presentation can be used to learn the idea behind ntopng and highlight the main design principles. We are also glad that this presentation has been accepted for submission consideration at the Italy in a Day contest, so it might have the chance to become part of this upcoming movie. …

It has been a busy summer here at ntop. Since the initial ntopng 1.0 release, we have tried to fill the gap in terms of missing with respect to the original ntop. This post is to update you about the new features of the upcoming 1.1 release schedule for this fall and that are currently available in the SVN development tree: Ability to support multi-interfaces. This means that you can repeat on the command line “-i <interface>” multiple times, one per interface you want to add. Use of HTTP sessions …

After 15 years since the introduction of the original ntop, it was time to start over with a new, modern ntop. We called it ntopng, ntop next generation. The goal of this new application are manyfold: Released under GNU GPL3. Feature a modern, HTML5 and Ajax-based dynamic web interface (caveat: you need a modern browser to use ntopng). Small application engine, memory wise and crash proof. Ability to identify application protocols via nDPI, ntop’s open-source DPI (Deep Packet Inspection) framework. User’s ability to script, extend, and modify ntopng pages coding …
