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 …

Using WeChat For Delivering ntopng Alerts
WeChat is a multi-purpose messaging, social media, and mobile payment app developed by Tencent in China. Our Chinese-speaking users requested for a long  time an integration of ntopng with it, and this is to announce it. By integrating ntopng alerts with WeChat, users can conveniently access network notifications within a platform they are already comfortable with. Overall, integrating ntopng alerts with WeChat enhances the user experience by providing timely, centralised, and customisable notifications directly to users’ preferred communication platform. So, we are happy to announce that it is now possible …

Using ClickHouse Cloud with ntopng
We are happy to announce that from the latest ntopng dev (6.1) version, ntopng supports exporting data (flows & alerts) to ClickHouse Cloud. Below you can find a step-by-step guide. Quick Start First of all let’s start by creating our account and service on the ClickHouse Cloud (you can find the official guide here); remember to save the ClickHouse username and password used for accessing your database. After that we have to jump to the ‘Connect’ section: Then, we have to select MySQL, turn on “Enable the MySQL protocol” and …

Fixing Packet Deduplication: Introducing nDedup
When it comes to monitor a busy network, network monitoring tools can become bogged down, or even worse produce misleading information for your analysis, by a hidden culprit: duplicate packets. Imagine a firehose of data streaming across your network, much of this data can be redundant, with identical packets being sent multiple times due to retransmissions or mirroring configurations. As an example, when a SPAN (Switch Port Analyzers) port is used to mirror ingress and egress direction of switch ports, the resulting mirrored traffic might contain up to 50% of …

ntop Cloud: Basic Concepts
We have designed the ntop Cloud as a way to securely interconnect customer applications deployed across hosts in heterogeneous environments not necessarily directly interconnected. Initially the goal of ntop Cloud is to enable users to administer easily these applications, update/restart/stop/start them with a mouse click, reconfigure them, and supervise their activities. Future SaaS (software as a service) features are planned but not a short term goals. The idea is to simplify application deployment, check application status regardless of the physical network, detect restarts etc. things that before the ntop Cloud …

ntop Cloud: Security Design and Architecture
In late 2023 we have announced the beginning of a new project we have called ntop Cloud. The first goal of this project is to enable ntop applications to communicate regardless of the network topology where they are deployed, This in a secure way. In essence we want to create a new network overlay that allow ntop applications to communicate and share data. Some use cases: Be notified when a ntop application is no longer active or more in general when it changes its status. Implement a public web interface …

How Historical Traffic Behaviour Analysis Works
In ntopng we have implemented various techniques for analysing historical traffic. This post shows you the options available: In timeseries you can see the current traffic rate (line) or the traffic rate of the previous period of time (dotted). This allows you to visually analyse when traffic deviates from previous period of time (see for instance in the chart below the traffic drop happened at 10 AM). 2. You can trigger interface alerts based on statistical traffic analysis (exponential smoothing) when traffic exceeds (up/down) its baseline. Note that when this …

DoS Detection Using ntopng and NetFlow/IPFIX
Recently ntopng has been used in academia for detecting DoS (Denial of Service) attacks using NetFlow flows. In this thesis (note that the document it is written in Italian) it is shown how ntopng has been successfully used collect flow and use them to detect DoS attacks. Enjoy ! …

How ntopng Host Traffic Accounting Works
Despite ntop has implemented rich network metrics over the years, the two most important metrics that people keep asking us are volume (how much) and time (how long).  Timeseries offer a quick view of the traffic and allow people to immediately spot traffic peaks or absence of transmissions. They are good for traffic analysis but are too complex for producing accounting data and comparing usage overtime. For this reason ntopng provides for each local host an additional feature that allows you to see immediately the amount and time that a …
