nDPI is a ntop-maintained superset of the popular OpenDPI library. Released
under the LGPL license, its goal is to extend the original library by adding
new protocols that are otherwise available only on the paid version of OpenDPI.
In addition to Unix platforms, we also support Windows, in order to provide
you a cross-platform DPI experience. Furthermore, we have modified nDPI do be
more suitable for traffic monitoring applications, by disabling specific
features that slow down the DPI engine while being them un-necessary for
network traffic monitoring.

The nfdump tools collect and process netflow data on the command line.
They are part of the NFSEN project which is explained more detailed at
http://www.terena.nl/tech/task-forces/tf-csirt/meeting12/nfsen-Haag.pdf

pmacct is a small set of passive network monitoring tools to measure, account, classify and aggregate IPv4 and IPv6 traffic; a pluggable and flexible architecture allows to store the collected traffic data into memory tables or SQL (MySQL, SQLite, PostgreSQL) databases. pmacct supports fully customizable historical data breakdown, flow sampling, filtering and tagging, recovery actions, and triggers. Libpcap, sFlow v2/v4/v5 and NetFlow v1/v5/v7/v8/v9 are supported, both unicast and multicast. Also, a client program makes it easy to export data to tools like RRDtool, GNUPlot, Net-SNMP, MRTG, and Cacti.

Power-calibrate calibrates the power consumption of a mobile device that has
a battery power source or of an modern Intel device has RAPL support.
It will attempt to calculate the power usage of 1% of CPU utilisation
(and 1 instruction and 1 cpu cycle if perf is available).

Powerstat measures the power consumption of a mobile PC that has a battery
power source. The output is like vmstat but also shows power consumption
statistics. At the end of a run, powerstat will calculate the average,
standard deviation and min/max of the gathered data.

The radcli library is a library for writing RADIUS Clients. The library's
approach is to allow writing RADIUS-aware application in less than 50 lines
of C code. It was based originally on freeradius-client and is source compatible
with it.
