n2disk

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 then filter captured packets. Once you have filtered your favourite packets (based on a BPF filter and a time span) you can then download them to your PC or reproduce them at line rate (or at any speed you like). Even BPF filters are simplified with the nBox thanks to the ability to drag and drop filtering expressions …

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 …

nProbe

Monitoring Mobile Networks (2G, 3G, and LTE) using nProbe
Monitoring mobile networks traffic has been traditionally perceived by the telecommunications industry as something complex, costly, proprietary. This is unfortunately one of the few fields where the open-source movement  has not been able to spread much, where vendor lock-in is still the standard. Last year we visited the Mobile World Congress in Barcelona to understand more about this world (btw, it’s a crazy expo as the  cheapest entry ticket costs 900$ and up), and the conclusion is that mobile terminals are pretty open thanks to Android, but the network is …
