You should look at these: http://mrtg.saintjoe.edu/mrtg/ratelimit/ http://www.freenet.org.nz/python/pyshaper/ http://sourceforge.net/projects/rcc http://www.shurdix.org/ I don't know if any of these is exactly what you want because the errors in wireless cause problems for traffic shaping, but you will certainly find lots of ideas and at least some answers. -- gypsy _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
