ntopng has been traditionally used to passively monitoring network traffic. However as years ago IDS (Intrusion Detection System) became mature products and eventually became IPS (Intrusion Prevention System), it was time to add inline traffic capabilities in ntopng. This post gives you s sneak preview of this new feature (still under development) that will be […]
Come to see the new ntopng at CeBIT 2015
As you might have noticed, we are busy working at ntopng. We will soon publish a blog post where we summarise the current activities and what is still missing before the next version of ntopng will be released. However we believe that while communicating through the Internet is a convenient way to reach the ntop […]
ntop 2015 Roadmap
Like every year, we have made a short-term plan for the first half 2015. As we are a research-oriented company, we plan to tackle open issues or provide better answer to existing ones. This is our short list of activities we are carrying on: 40 Gbit We are in the process of supporting the new Intel X710 […]
Using ntop Applications with Docker and OpenStack
In order to ease the deployment of our applications, in addition to source code distribution, we have released binary packages (x64 and ARM) for CentOS/RedHat and Ubuntu/Debian. For PF_RING, that requires to be compiled against the installed kernel version, we have moved to DKMS so that you are no longer required to use the same kernel version […]
Combining System and Network Visibility using nProbe and Sysdig
Introduction When in 1998 we have started the development of the original ntop, there were many Unix tools for monitoring network traffic: ping, tcpdump, netstat, and many others. Nevertheless we have decided to develop ntop, because there was no tool able to show on a simple way what was happening on our network. Early this year we […]
Introducing nProbe v7
After more than three years of work, we are announcing the release of nProbe v7. This is a major evolution of v6 that many of you used in the bast few years. In essence we have worked a lot for improving the application performance, supporting new protocols (including mobile 3G/LTE network monitoring), adding new information […]
Running ntopng and nDPI on MacOSX
On Mac OS X users expect simple tool packaging and installation. Initially we planned to distribute .dmg files containing our apps, but then we have decided that in order to support current and future OSX version more easily, this was not the way to go. For this reason we have added support for packaging systems […]
Released nDPI 1.5.1 and ntopng 1.2.1
Today we have released a maintenance version of both nDPI and ntopng that address minor issues present in the previous stable release. In particular for ntopng we have addressed many small security holes identified by security researchers (our thanks go to Luca Carettoni), and thus we encourage you to upgrade when possible; note that for all […]
Active vs Passive Polling in Packet Processing
From time to time, PF_RING users ask us whether they should use passive polling techniques (i.e. call pfring_poll()) or use active polling that basically means to implement an active loop until the next packet to process becomes available. All those who have read a programming book or attended university classes, might answer that polling is the answer. […]
Using sysdig from PF_RING (and soon from all ntop apps)
Months ago Draios Inc introduced sysdig a kernel module and user-space library for capturing systems events and thus analyse what is happening on a Linux box. The idea has been immediately appealing for us at ntop, this for many reasons: With our tools we can analyse network packets, extract metadata (e.g. URLs, network delays, username […]
