How To Install ntopng on Ubuntu 18.04
Introduction
In this tutorial we learn how to install ntopng on Ubuntu 18.04.
What is ntopng
ntopng is:
ntopng is the next generation version of the original ntop, a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntop is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Win32 as well.
ntopng users can use a web browser to navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. In the latter case, ntop can be seen as a simple RMON-like agent with an embedded web interface. The use of:
- a web interface
- limited configuration and administration via the web interface
- reduced CPU and memory usage (they vary according to network size and traffic)
What ntopng can do:
- Sort network traffic according to many protocols
- Show network traffic and IPv4/v6 active hosts
- Store on disk persistent traffic statistics in RRD format
- Geolocate hosts
- Discover application protocols by leveraging on nDPI, ntop’s DPI framework
- Characterise HTTP traffic by leveraging on characterisation services provided by block.si. ntopng comes with a demo characterisation key, but if you need a permanent one, please mail [email protected]
- Show IP traffic distribution among the various protocols
- Analyse IP traffic and sort it according to the source/destination
- Display IP Traffic Subnet matrix (who’s talking to who?)
- Report IP protocol usage sorted by protocol type
- Act as a NetFlow/sFlow collector for flows generated by routers (e.g. Cisco and Juniper) or switches (e.g. Foundry Networks) when used together with nProbe
- Produce HTML5/AJAX network traffic statistics
