Filtering Terabytes of pcaps using nBPF and Wireshark
In a previous post we introduced our new nBPF library that able to convert a BPF filter to hardware rules for offloading traffic filtering to the network card. We did not mention…

n2disk 2.6 Just Released
This is to announce the release of n2disk 2.6. In this release we have made many changes to the indexing system adding a new flow-based index that should improve packet retrieval as…
How to Build a 2×10 Gbit Packet Recorder using n2disk and PF_RING (2016 Update)
Earlier in 2014 we advised how to build a continuous packet recorder using n2disk and PF_RING. Since that time computing architectures have progressed, we have added support for new ethernet controllers, and…
Building a (Cheap) 2×10 Gbit (Continuous) Packet Recorder using n2disk and PF_RING
Continuous packet recorders are devices that capture network traffic and save it to disk. The term continuous means that this activity is performed "continuously" until the device is active and not just…
Visualising n2disk Captured Traffic using CloudShark
Introduction ntop users are familiar with n2disk and the nBox web interface that ease its use. As you know, the nBox includes a small web-based tool that allows you to preview pcap…
Introducing on-the-fly 10 Gbit pcap compression on n2disk
Compressing pcap produced by n2disk is a good idea for a few reasons: It allows disk space to be saved as compressed data takes less space on disk. It enables the creation…
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…
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…
Learning The ntop World of Apps
The main criticism to ntop is the lack of documentation. This is because we have to maintain many projects, have little time, and also because we prefer coding to documentation. We decided…
How to build yourself a nBox Probe and Packet Recorder
If you need a network probe or a packet recorder you have two options. Grab a turn-key nBox or built it yourself using our software. In the first case you will receive…
Filtering n2disk-captured Packets and Replaying them at 10 Gbit using the nBox
The nBox is not just a no-cost web GUI for ntop products, but it's a totally new experience for dealing with pcap files. n2disk is able to index packets while capturing and…
Using n2disk for 10 Gbit line-rate packet-to-disk
Packet-to-disk is the ability to dump network packets to disk. This activity is important for implementing a sort of "network time machine" so that when something unexpected happens, you have the ability…
