Introducing ntopng 1.2
ntopng 1.2 is the result of  10 months of work. We have tried to both introduce new features, and make the product more robust, easy to use, and modern. The result is a simple tool with a refreshed GUI, user preferences, and new reports to display data in new ways. Leveraging on the multi-interface support, ntopng (unless a specific interface is specified) listens on all network interfaces so that you do not have to play with the command line to move from one interface to others All the tables are …

Introducing ntop Video Tutorials
We have been asked many times to create some videos that introduce novice users to our tools and products. Although English is not our mother tongue, we have decided to take this request seriously and start uploading them on the ntop channel. This said we need your help and we hope that you will contribute by sharing your videos with the whole community. …

Creating a hierarchical cluster of ntopng instances
As you know via ZMQ you can use ntopng as collector for nProbe instances. You can decide to merge all probes into one single ntopng interface (i.e. all the traffic will be merged and mixed) or to have an interface per probe. Example: Start the remote nProbe instances as follows [host1] nprobe --zmq "tcp://*:5556" -i ethX [host2] nprobe --zmq "tcp://*:5556" -i ethX [host3] nprobe --zmq "tcp://*:5556" -i ethX [host4] nprobe --zmq "tcp://*:5556" -i ethX If you want to merge all nProbe traffic into a single ntopng interface do: ntopng -i tcp://host1:5556,tcp://host2:5556,tcp://host3:5556,tcp://host4:5556 If you want to …

Introducing nProbe Splunk App for (Free) Network and Application Monitoring
Splunk is a popular realtime data capture, aggregation, and data visualisation system. Designed initially for handling application logs, in its current version is available  with a free enterprise license can index up to 500 megabytes of data per day. We have decided to use Splunk to capture and index in realtime flows generated by nProbe, and in particular those that contain non-numerical information, such as HTTP URLs for instance. The versatile of splunk is such that it can be easily customised with a few mouse clicks, so that new reports, views …

Napatech and ntop will demonstrate 10 Gbps capture-to-disk at RSA and MWC
Napatech, the world’s leading supplier of network analysis adapters, and ntop, the renowned traffic monitoring software expert, today announced a collaboration focused on accelerating time to market for high-performance network management and security appliances. The first initiative is a 10 Gbps capture-to-disk solution that will be demonstrated at Mobile World Congress and RSA, February 24-28. Capture-to-disk is fast becoming a critical capability for appliances used in network management and security as well as real-time big data analytics, but it requires expertise to implement, especially for high-speed applications. Commercial-off-the-shelf (COTS) servers offer …

Using n2n with Amazon (AWS) EC2
Although we currently have no time to further develop n2n (we have put the project on hold until we have time to work at it again), this tool is still widely used. This article (courtesy of Stuart Buckell) shows how to use n2n to enable broadcast and multicast support on Amazon (AWS) EC2, which is required for certain enterprise applications and protocols. Enjoy! …

Scripting ntopng with Lua
The ntopng architecture is divided in three layers: Ingress layer (flow or packet capture). Monitoring engine: the ntopng core. Lua scripting engine Data export layer (via web, syslog or log files). Thanks to the scripting engine, ntopng is fully scriptable. This means that via Lua you can extract the monitoring information and report it into HTML pages or export it to third party applications. The ntopng Lua API is pretty simple it consists of two classes, ntop and interface. ntopng also comes with some example scripts that highlight the main …

Running nProbe and ntopng on Ubiquity EdgeRouter Lite
On this blog we have already discussed on how to compile and run ntopng and nProbe on a BeagleBoard and Raspberry Pi. Now we explain (courtesy of  Shane Graham) how to achieve the same on a Ubiquity EdgeRouter Lite, a cheap yet powerful router. First, setup the proper Debian repository: configure set system package repository squeeze components 'main contrib non-free' set system package repository squeeze distribution squeeze set system package repository squeeze url http://http.us.debian.org/debian set system package repository squeeze-security components main set system package repository squeeze-security distribution squeeze/updates set system package repository …
