Accurate 10 Gbit Traffic Reply Using disk2n
n2disk is a software application that allows to dump traffic to disk at line rate (10 Gbit full duplex) with high-accurate timestamps. This both using networks cards featuring hardware timestamps and also with software timestamps. Most companies focus just on capture to disk, whereas we believe that it is also compulsory  to provide solutions for traffic replay by exploiting these high-accurate timestamps that have been saved on pcap files. This activity is quite challenging. Replying traffic with high-precision timestamps it is necessary for instance whenever we want to reproduce exactly the …

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 …

Introducing nBox 2.0 (aka how to use/configure ntop apps using a web GUI)
Years ago we decided to create the nBox appliance as turn-key solution for those that were not fans of the command line. Then we decided to rewrite the nBox GUI to make it simpler, more modern, and usable by all ntop users, to configure ntop, nProbe, n2disk, PF_RING and DNA.   In essence we have created a new web interface that can simplify your configurations, assist with complex things such as core affinity or DNA configuration, and let you focus on ntop applications rather than on their configuration. You can download …

Say hello to nDPI (Network DPI)
The equation “port = (application) protocol” no longer holds. DPI (Deep Packet Inspection) is the way to detect known protocols on non-known ports (e.g. http on ports other than 80) and traffic on know port that is not the one we expect (e.g. skype on port 80). On a nutshell, we need to look at packet content and see what’s inside. P2P protocols have been designed from day one with the ability to circumvent network policies in order to reach their peers, and they are good example of places where …

PF_RING 5.0 Introduced: DNA 1/10 Gbit and vPF_RING
We’ve just cut the code of PF_RING 5.0. As it contains many changes with respect to the previous version, it deserved a major version number. We refreshed our DNA drivers to 1 Gbit Intel NICs (e1000e and igb families) in addition to the existing 10 Gbit DNA driver. All the DNA drivers source code is stored inside the PF_RING SVN. You can just install the DNA driver, and use our test applications (pfcount for receiving packets, and pfsend for generating/reproducing traffic) for enjoying 1/10 Gbit RX/TX wire-speed using commodity adapters. …

Power to see all
Almost a decade ago Dr Ian Graham was in Europe for a series of conferences and I have met him in person along with other people from Politecnico di Torino, that were developing winpcap (one of the key guys of the group, Loris Degioanni, at that time was visiting Endace, thus was not present at the meeting. Loris later become a successful entrepreneur having founded Cace, now Riverbed). For me it was a big pleasure to have such meeting, as Endace was in the early days (and also all of …

Say hello to NetFlow-Lite (NFLite)
As you all know, NetFlow has been initially designed for routers (or L3 switches if you wish), contrary to sFlow that instead has been deployed mostly on switches. In this view, people use NetFlow just for monitoring internet traffic, as NetFlow is not supported across the product portfolio due to dedicated ASIC required. NetFlow-lite (first introduced with Catalyst 4948E) bridges the gap by providing a lightweight solution that allows capturing of important flow information through packet sampling mechanisms combined with the extensibility of NetFlow version 9 and IPFIX. What is NetFlow-Lite? In …
