ntopng

ntopng is computer software for monitoring traffic on a computer network. It is designed to be a high-performance, low-resource replacement for ntop. The name is derived from ntop next generation. ntopng is open-source software released under the GNU General Public License (GPLv3) for software. Source code versions are available for the operating systems: Unix, Linux, BSD, Mac OS X, and Windows. Binary versions are available for CentOS, Ubuntu, and OS X. A demo binary is available for Windows that limits analysis to 2,000 packets. ntopng's engine is written in the programming language C++. The optional web interface is written in Lua.

ntopng relies on the Redis key-value server rather than a traditional database, takes advantage of nDPI for protocol detection, supports geolocation of hosts, and is able to display real-time flow analysis for connected hosts.

Sample use

 
ntopng --dns-mode 1 --interface 5 --daemon --redis localhost:6379 --verbose

Explanation: run ntopng executable, set DNS mode to decode DNS responses and resolve all numeric IPs, use fifth network interface, operate in daemon mode, use Redis server running on local host, and operate in verbose mode.

gollark: Phone #1 died to screen damage and then being consigned to wait for replacement parts forever, phone #2 died to a manufacturing defect (friend's identical one had it too) where the micro-USB port apioformed, phone #3 mysteriously had touchscreen failure, phone #4 is working but has a somewhat degraded battery.
gollark: All my phones have suffered damage of some kind to non-core parts, because apparently the computer bits are extremely reliable.
gollark: You would need an ESP32 *and* screen thing *and* 4G modem.
