You’re Invited to the ntop and Wireshark Users Group Meeting

On November 7th we will be organising the ntop meetup during the Sharkfest EU 2017 that will take place in Portugal. You can find all details here. This year we will be focusing on cybersecurity, IoT and user traffic monitoring, as well on Wireshark. In fact during our talk at Sharkfest we won’t have enough time to explain in detail all our activities for turning (or complementing) Wireshark into an effective monitoring tool and not just a packet dissector. We welcome all users of our community (attendance of Sharkfest EU is …

Announcing ntopng and Grafana Integration

Disclaimer This article is outdated: please see this document for using ntopng with grafana This is to announce the release of the ntopng Grafana datasource that you can find on the grafana website. Using this plugin you can create a Grafana dashboard that fetches data from ntopng in a matter of clicks. To set up the datasource visit Grafana Datasources page and select the green button Add a datasource. Select ntopng as the datasource Type in the page that opens. The HTTP url must point to a running ntopng instance, …

20 Years of ntop and Beyond

This month it’s 20 years that I have started the ntop project. Initially it was a hobby project, willing to understand what was really flowing on a network after having spent 5 years playing with OSI that was clearly a dead end (whoever used FTAM to download a file and compared it with FTP/NFS or drag-and-drop on a Mac desktop, understands what I mean), even for me that just graduated from university. My initial idea behind ntop was to create a simple tool able to enable network visibility without having …

When Live is not Enough: Connecting ntopng and nProbe via MySQL for Historical Flows Exploration

Using nProbe in combination with ntopng is a common practice. The benefits of this combination are manyfold and include: A complete decoupling of monitoring activities (taking place on the nProbe) from visualization tasks (taking place on ntopng); The capability of building distributed deployments where multiple (remote) nProbe instances send monitored data towards one or more ntopng instances for visualization; A comprehensive support for the collection, harmonization and visualization of heterogeneous flow export protocols and technologies, including NetFlow V5/v9/V10 IPFIX and sFlow; Full support for any proprietary technology that sends custom …

Network Monitoring Deep Dive: Interview with Scott Schweitzer

In early August, Scott Schweitzer interviewed me about network monitoring and packet capture. The conversation has been very broad, and I have covered various topics ranging from packet capture, network traffic analysis, deep packet inspection, IoT (Internet of Things) and cybersecurity. You can hear my view on this market, and what we’re doing at ntopng to tackle new challenges, as well what we envisage the (hardware) networking industry should provide developers in terms of new products. This is because after being almost 20 years on this industry, looking back at …

How to use ntopng for Realtime Traffic Analysis on Fritz!Box Routers

Fritz!Box routers are popular devices that many people use to connect to the Internet. Inside these routers there is a hidden (i.e. not accessible from the router web admin page, but that you access directly with a web browser by writing the whole URL) URL http://192.168.2.1/html/capture.html (BTW replace the 192.168.2.1 IP address with your Fritz!Box router IP if you have changed it) that can be used to dump router traffic in pcap format. While pcaps are good for troubleshooting, most people need to know what is happening on their network in realtime, …

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 see the video (and slides) of our presentation at the Sharkfest US 2017 conference.     …

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 pcap indexes How to turn wireshark into a traffic monitoring tool able to measure traffic and network latency. For those who have not attended the session (recording will appear soon on the sharkfest web site), …

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 integration of ntopng with Grafana that we plan to complete in July. Here you can see the presentation slides  where you can have an idea of the work we’re doing. If you are interested in using …

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 probe and collector. For all those interested in the whole changelog, below you can find the main changes we have implemented in the past months. In summary we have made nProbe better adding new extensions, …

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 (even on the go), improved significantly the Windows version (yes Win 10 is supported out of the box), improved performance, reworked the GUI in many aspects, improved significantly the inline traffic mode, improved FreeBSD support. As …

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 nDPI-detected protocols by adding an ethernet packet trailer that is then interpreted and displayed inside the Wireshark GUI using the companion lua script. If you’re planning to attend the Sharkfest US 2017, we will present …
