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.
