Dumping sFlow/NetFlow/IPFIX flows in pcap format can be very useful for troubleshooting or for creating a compact traffic dump. For instance you can dump flow traffic with n2disk (wireshark, or tcpdump) and store them in pcap format, and eventually share them with a shared disk or sent via email. Flows are usually analysed live with […]
ipt_geofence: Protecting Networks using Geofencing, Blocklists and Service Analysis
Last week the ntop team has organised the network devroom at FOSDEM 2024, that took place in Brussels on Feb 2-3. During the devroom we have presented one tool named ipt_geofence that we have created for protecting our network infrastructure and generate blacklists that can be used with ntop tools (this task is still ongoing). […]
How Sampling and Throughput Calculation Works: NetFlow/IPFIX vs sFlow vs Packets
ntop tools are able to collect various type of flows NetFlow/IPFIX (including dialects such as J-Flow, NetStream) and sFlow/NetFlowLite, this in addition to packet capture/processing. We have decided to seamlessly handle all these formats so that the user does not have to know the inner details of them. so what you do is the usual […]

Securing ClickHouse and MySQL Flow Storage
ntopng stores flows data in various databases including MySQL, Elastic and ClickHouse that is the database storage that we have selected as it outpaces the others in terms of speed and reduced disk space. ClickHouse is a columnar database and while it is very fast during data access, it is optimised for batch data insertion. […]
nDPI: Internals and Frequent Questions

How ntopng Merges Vulnerability Scan with Traffic Monitoring for Better Cybersecurity
ntopng was initially designed as a passive traffic monitoring tool. Over the years we have added active monitoring features such as network discovery, SNMP, and now vulnerability scan. A network vulnerability scanner is a tool designed to identify vulnerabilities (often know as CVEs) in network services such as a web or SSH server by performing […]
