How to Monitor and Troubleshoot an Unfamiliar Network
At ntop we use wireshark to dissect traffic and to learn how to make our tools better. We’re not typical packet-oriented users however, as we want to see traffic as a whole and not packet-by-packet. This has been the motivation for contributing to wireshark for extending it towards a more monitoring-oriented tool. Above you can …

How to Enhance Wireshark with DPI, latency measurement and more
This week at Sharkfest US 17, we have presented the ntop contributions to wireshark. In particular: How to use nDPI to complement Wireshark traffic classification How to remote capture on a remote box at 10/401/100 Gbit and stream traffic securely to wireshark via SSH Same as above but extracting packets from TBytes (of pcaps)  using …

Integrating ntopng with Grafana
Last week the NYC Metrics and Monitoring meetup invited ntop to give a talk. The topic was how to open ntopng so that it can become a gateway for producing network metrics that could be used by popular applications and frameworks such as Snap-io, Prometheus or Influx. The first result of this activity is the …

Introducing nProbe 8.0, the ntopng flow companion
The current nProbe 8.0 release contains many changes with respect to the 7.x series. We have optimised the code, added the ability to collect non standard fields (e.g. Cisco AVC), improved Kafka export, and reworked many tiny details to make the tool a stable solution for all those looking for a flexible and versatile flow …

Introducing ntopng 3.0
If you have enjoyed ntopng 2.x, we believe you will like 3.0 even more as we have worked for almost one year to this release. We have modified many things, improved security in ntopng (in the cybersecurity days this is the least we could do), added layer 2 visibility, improved metrics calculations, added alerts support …

Say hello to nDPI 2.0 (with wireshark integration)
nDPI 2.0 is a major release that: Consolidates the API, in particular for guessing new protocols or notifying nDPI that for a given flow there are no more packets to dissect. Introduces nDPI support into Wireshark by means of a lua script and extcap plugin. Available via an extcap interface, the plugin sends Wireshark the …

Monitoring Network Devices with ntopng and SNMP
Summary SNMP is widely used for network monitoring. Being able to remotely monitor network devices is fundamental to have a clear picture of present and past network health. ntopng systematically interacts with SNMP devices to provide historical and real-time insights on the network. ntopng SNMP support Simple Network Management Protocol (SNMP) is one of the …

Monitoring IoT and Fog Computing: Challenges and Solutions
Since last year we are designing a solution for monitoring IoT and Fog computing devices. This is becoming a hot argument since they are more and more used to create large Internet attacks and also because our privacy can be affected by this new computing trend. While we do not have a complete solution ready, we …

Introducing nScrub: Powerful yet Affordable DDoS Mitigation
ntop has always tried to make the Internet a better place by developing many open-source network monitoring tools, and releasing all the software at no cost to non-profit and education. A few years ago, Qurium/VirtualRoad, a swedish foundation offering secure hosting to independent online news outlets and human rights organisations, contacted us. The reason was that …

Introducing n2disk 2.8 with Microburst Detection
Together with PF_RING 6.6, today we also released n2disk 2.8. In this release we introduced support for microburst detection in order to spot traffic bursts, which is crucial in identifying potential capacity issues and troubleshooting packet loss in network equipments. We also improved our “fast” BPF engine extending the supported primitives, and improving the ability to …
