Positioning ntopng vs nProbe for Traffic Analysis
Recently we have compared the use of nDPI in a realtime application (ntopng) and a near-realtime (nProbe). We have captured a short pcap with some mixed traffic and analysed it with both applications. The expectation was to find comparable results between the two applications, but this happened only partially. This blog posts explains the main differences between the two tools and why there are some discrepancies in results. In our tests, we have configured both nProbe and ntopng to analyze the same pcap and write results on two different ClickHouse …

HowTo Extend ntopng with new Host/Flow Checks and Alerts
ntopng can be easily extended with new host/flow checks and alerts. They are developed in C++ with a few Lua files used by the UI to configure the check and format the emitted alerts. In order to introduce you to thir development, we have written a short guide that shows you step-by-step how to develop a simple check and alert. If you want you can see a code example of host check that rtiggers an alert when a server contacted a new port after a learning period. If you have …

HowTo Export ntopng Alarms to Checkmk Event Console
Checkmk is a popular platform for monitoring IT infrastructure. ntopng has been integrated in Checkmk some time ago, enabling users to provide traffic visibility in additional to classic bytes/packets metrics. As ntopng is able to produce traffic alerts that, we have decided to extend ntopng in order to export alert information towards Checkmk event console where alerts are received.This guide will walk you through configuring ntopng and Checkmk to enable this functionality. In order to do so, within ntopng, it’s necessary to configure a new Endpoints as well as a …

Advancements in Traffic Processing Using Programmable Hardware Flow Offload
This week we have presented at the IEEE HPSR (IEEE International Conference on High Performance Switching and Routing) our latest work that shows how nProbe can benefit of acceleration provided by modern SmartNICs to achieving multi-100 Gbit traffic processing (both passive and inline) on low-end servers while deep-packet inspecting traffic using nDPI. If you want to know more about it, you can view the presentation slides, or read thw paper. Your feedback is welcome. Enjoy ! …

ELLIO for ntopng: HowTo Prevent CyberAccidents Using Blacklists
Time is one of the main problems in cybersecurity. Detecting issues after they have happened can cost you money and resources to restore the system. Network traffic monitoring tools have as goal to show what is happening on a network.  Traditionally, monitoring protocols such as IPFIX/NetFlow export monitoring data periodically and often limit their analysis to the protocol header, thus the flow collector is partially blind as it is informed after a certain event happened with limited contextual information. In ntop tools we operate in real-time with pre-labelled information thanks …

HowTo Use Cloud Licenses
As discussed in our spring webinar, it is now possible to use (in beta) cloud licenses with ntopng and nProbe. Contrary to standard licenses that are bound to a physical system (based on the systemId), cloud licenses are “floating” as the same license file can be used on multiple hosts, of course not simultaneously (i.e. only one system at time can use the license). This is good news for those who use containers or VMs as they do no have to pay attention to the systemId anymore. If you want …
