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…

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…
