I’ve put together a guide on how to configure a Windows nProbe to send NetFlow v5 to your favorite NetFlow collector and analyzer. Network administrators need to pin-point problems, understand bottlenecks but in particular to know exactly what is the cause of a certain problem. As shown in Figure 1, nProbe is listening to port 2055 and translate this *flow data into json for ntopng to process. Most software work without licenses.

It's a very advanced router and one of the possibilities is sending netflow data. ntop – the company behind nProbe – provides a suite of leading web traffic analysis products. Here we configure our The communication between nProbe and ntopng happens though ZeroMQ that decouples ntopng from nProbe. yum install --enablerepo=epel pfring n2disk nprobe ntopng ntopng-data cento PF_RING is now packaged without ZC drivers so you can optionally install them: yum install pfring-drivers-zc-dkms Most software works without nProbe on a public network/IP, ntopng on a private network/IP protected by a firewall.
