Released Cento 2.0: Hardware Flow Table Offload, Avro Export and Much More
This is to announce that Cento 2.0 is out! This new major release introduces many new great features. First of all it adds support for offloading flows to Napatech SmartNICs featuring Flow Manager. This new feature has been presented at IEEE HPSR (IEEE International Conference on High Performance Switching and Routing) and demonstrated to provide a significant performance boost and dramatically reduce the PCIe and memory bandwidth utilisation when processing 100 Gbit (or more) links with full-speed traffic. This can be used both by standard cento to accelerate passive monitoring, …
nProbe

Released nProbe 10.6: Reworked GTP support, Improved Kafka/ZMQ Export, Several Fixes
This is to announce the release of nProbe 10.6 that includes many changes in a couple of selected areas: Mobile traffic analysis (GTPv1 and GTPv2) and GTP-C/GTP-U correlation has been rewritten to support complexity of modern mobile networks.  nProbe is now more friendly when talking ZMQ/Kafka (hence with ntopng) as it can report various statistics and export of specific information elements has been optimised to improve performance. In addition nProbe supports the latest nDPI version that has been optimised in memory and that features almost 500 application protocols, that is …
PF_RING

Released PF_RING 8.8.0: Flow Table Offload and nVidia BlueField Support
This is to announce a new PF_RING release 8.8.0! This release adds generic support for flow table offload, which is currently supported on Napatech adapters with Flow Manager enabled. This new technology has been successfully used to accelerate nProbe Cento when running with DPI enabled on multi 100 Gbit traffic (both passive and inline) and the work has been presented at IEEE HPSR (IEEE International Conference on High Performance Switching and Routing). This also adds support for zero-copy transmission on Napatech adapters, to reduce bandwidth utilisation and latency when forwarding …
nDPI

Released nDPI 4.10: 421 Protocols, 55 Flow Risks, Several Improvements, Getting Ready for FPC
This is to announce the release of nDPI 4.10. This release adds many improvements and new detected protocols. For this reason future releases will be scheduled more often on a 4 or 6 months (hard) basis in order to provide you constant updates on a predictable timeframe, Beside adding many dissectors, this release paves the way towards First Packet Classification (FPC) that is an attempt (for selected protocols) to detect the application protocol DPI at the first packet of a connection. Of course this is a challenge, and it won’t …

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 ! …

Extended Multilanguage Support in ntopng: Korean, Spanish and French
This is to announce that ntopng now enables users to use a new languages: Korean, Spanish and French.  We have also improved translations of German and Italian. The translation is done using an automatic tool so, we cannot guarantee that the translation is completely correct. Error or typos are accepted as a GitHub issue: please open a ticket if you find problems. To change language click on the top right icon in ntopng and enter in the admin page A popup will open, select language and a list of available …
