netics   an extensible network statistics collector. it puts the network interface in promiscuous mode and feeds the data stream (after it strips off the appropriate protocol headers), 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 lwz statistic requires much less data.
statistics    lzw entropy, maurer entropy
platforns    developed on openbsd, tested on linux and other unix like platforms
availability   netics 2.0 is available here. openbsd port here.
