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 […]
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 […]
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 […]
HowTo Use nProbe to Detect and Shape Traffic Using DPI
Not all the nProbe users know that they can use nProbe not just as a passive monitoring tool, but also for shaping and dropping netwok traffic based on DPI. Ryan Claridge has filled the gap by writing a great article that explains that in detail. Enjoy !
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. […]
HowTo Analyse NetFlow/IPFIX/sFlow pcap Traces
Dumping sFlow/NetFlow/IPFIX flows in pcap format can be very useful for troubleshooting or for creating a compact traffic dump. For instance you can dump flow traffic with n2disk (wireshark, or tcpdump) and store them in pcap format, and eventually share them with a shared disk or sent via email. Flows are usually analysed live with […]
How Sampling and Throughput Calculation Works: NetFlow/IPFIX vs sFlow vs Packets
ntop tools are able to collect various type of flows NetFlow/IPFIX (including dialects such as J-Flow, NetStream) and sFlow/NetFlowLite, this in addition to packet capture/processing. We have decided to seamlessly handle all these formats so that the user does not have to know the inner details of them. so what you do is the usual […]
HowTo Build a 100 Gbit NetFlow Sensor Using nProbe Cento
When it comes to monitor a distributed network, to get a picture of the Network traffic flowing through the uplinks or on critical Network segments, NetFlow like technologies are usually the answer. nProbe Pro/Enterprise and nProbe Cento are software probes that can be used to build versatile sensors able to export flow information in many […]
nProbe 10.4 is now Available: Cloud Support and Agent Mode
This is to announce the release of nProbe 10.4. In this version we have made several improvements (including support for new platforms and distributions) as well merged the agent code into the main code base (via -T) on both Linux and Windows. This feature allows you to export (for traffic originated or terminated on the […]
nProbe Cento 1.20 Just Released
This is to announce the release of nProbe Cento 1.20, that is basically a maintenance release that fixes some issues, improved metadata export using nDPI, and adds new platform and distributions support. Below you can find the whole changelog. Enjoy ! Improvements Add ARM support Add support for dumping bad packets (–dump-bad-packets) Add support for […]
