Into the Flows: Collecting Data with nProbe and nTop

The role of these two components is pretty clear: nProbe has the role of collecting traffic data, while nTop makes that data visible and easily analyzable. There is something, however, that needs to be explicitly stated, which is to decide whether it’s ntopng that should contact nProbe or vice versa, and as we’re in a…

nTop and nDPI: How to Increase Network Traffic Analysis

nTop now uses the nDPI (network deep packet inspection) library to classify packets within network traffic for those protocols that either do not use a standard port (defined as well known ports like https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers and https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml) or that are dynamically assigned. In any case the need to classify not only the packet header but also…

Grafana for nTop: Realizing a Dashboard

A customer with a NetEye installation to which I had added the nTop module asked me if I could integrate nTop’s Grafana Dashboards, so they could view them by consulting NetEye’s ITOA Menu. The installation and configuration of nTop for this client, a task I had already conducted some time ago, was a matter of…

nBox to NetEye Elastic Module

A customer asked me to analyze their network flows, with a solution oriented towards using an nBox that collects NetFlow data from a router located away from the branch office, takes it in for analysis, and then sends it to a NetEye Elastic module, which act as an analysis console for that NetFlow data. The…

Distributed, Multi-Instance nProbe: NetFlow Analysis

A client with a really large number of routers installed at their client asked me one day to analyze each of those network flows. They hoped that an analysis tool would be able to discover and impose a multitenant configuration all on its own, so that access could be granted to final users while guaranteeing…

nProbe and nTop All-in-One (Single Node): Netflows Analysis

One of my clients with a number of routers installed at their own remote location asked me if I could analyze the network flows at multiple locations. Their network architecture is a full mesh, and thus has private subnetworks, data center environments, and even in some cases cloud providers. Complex architectures like this require increasing…

Chi si sta mangiando la banda? Scoprilo con ntopng

Chi riesce a sapere veramente quali sono i protocolli utilizzati nella rete locale? Solitamente con i netflow si può distinguere il traffico attraverso le porte L4 (80=http,443=https,..) ma non è più sufficiente. Alcune applicazioni usano invece porte dinamiche (vedi nfs, ftp, routed sap, …), altre le porte stesse, come si può allora essere in grado…

Identifizieren Sie Bandbreitenfresser mit ntopng

Wer von Ihnen weiß genau welche Protokolle im Unternehmensnetzwerk verwendet werden? Dank NetFlow können wir den Traffic der L4-Ports (80=http,443=https,..) unterscheiden, leider reicht das heutzutage aber nicht aus. Einige Applikationen verwenden dynamische Ports (siehe nfs, ftp, routed sap, …), andere nutzen die selben Ports, wie sollen wir diese noch voneinander unterscheiden? Erschwerend hinzu kommt, dass sich…

Find out who is eating your bandwidth with ntopng

Who really knows what are the protocols used in the local network? Usually with netflow you can distinguish traffic per l4 port (80=http,443=https,..) but this is no more sufficient. Some applications use dynamic ports (see nfs, ftp, routed sap, …), several applications use the same ports, how can we distinguish them? Applications grow and change really fast (like…
