My unix background is mainly Irix, for that, probably a picobsd-based bridge does the job fairly well. there is a floppy image at http://www.iet.unipi.it/~luigi/ip_dummynet/ which also has Weighted Fair Queueing enabled. > 2) Where I work: > we have a wireless 4.5 meg connection to the net, the boss wants to know > how much surfing/streaming audio/napster traffic we are doing, and from > which machines.
