There are 2 things: 1) I look after the Unix (Irix) boxes at a education facility that has about 400 machines running on 5 class C's, and a 10 meg connection to the net. There traffic has jumped from about 200 gigs a month to about 900 gigs a month, and I told them they should get a traffic shaping tool. The Cisco product to this costs about 15 000$, or so I am told, that has yet to be confirmed, so it seems like running all the traffic through a box is the way to go. My unix background is mainly Irix, a little bit of Linux, some Sun, HP and I actually did an install of FreeBSD4 about a month ago. I would like to set them up with a way to say this group of machines (called A), and this protocols, either get 1st priority or X megs (not sure if I? get an option on that), these machines (B) and these protocols get 2nd or 70% of X megs, and anything outside that (which I hope is all the streaming audio and napster traffic) gets very little. 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. He may want to traffic shape, that is why I mentioned both on the same box. There is 80 users, on 3 class c's, and we are also providing network access for a couple other small (less than 5 machines) clients in the building, and need to monitor their traffic ona monthly basis, to bill back at X per gig. (We will control their bandwidth via the router) > i would rather use ntop or trafshow or things like that. In ports/net, i > think. I will look into trafshow, I have not seen that before. ntop I have and like.
