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 …
nDPI

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 …

Detecting and Fighting Ransomware Using ntopng (yes including WannaCry)
These days many people are talking about ransomware and in particular of the problems created by WannaCry. Some ntop users contacted us asking if they could use our tools for detecting and stopping ransomware. While the best solution to these issues is to properly implement network security (that is a process, not a product in our opinion) by designing the network properly and keeping hosts updated,  it is usually possible to use ntopng to detect infections, block most of them, and have a list of hosts that might have been …

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 de-facto standards used to remotely monitor network devices such as routers, switches and servers, just to name a few. With ntopng Enterprise it is possible to consistently and programmatically interact with those devices to have a real-time view …

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 have some preliminary results and lessons learnt that are worth to be shared with our community. This is a presentation we created on this subject and that has been shown at the Wurth-Phoenix Roadshow (BTW …

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 after years mitigating attacks using proprietary appliances and servers running customised Linux kernel code based on netfilter, they reached the conclusion that those solutions were not affordable, or flexible, or fast enough. Their experience with …
