» netics

netics is an extensible network statistics collector. It feeds the data stream (after it strips off the appropriate protocol headers) to modules gathering statistical data, it then displays the results at speficied intervals, either in a “progress bar” mode or as raw statistics. Currently it supports 2 statistics, both involving entropy; LZW compressability and Ueli Maurer’s universal statistical test. Maurer’s test is a very good and comprehensive measure of entropy, but requires a large amount of data, the LZW statistic requires much less data.

netics is developed on OpenBSD/i386 and is tested on Linux 2.4/i386 and Mac OS X 10.3.

netics is released under a BSD license.
