Linux router stats software

[hapoo]

I really hope someone can help me on this one. I use my linux box as a router. I want a program that will give me stats on how much was uploaded/download each day/week/month etc., which days were the highest/lowest. and separate stats for each computer on the network. If this software doesn't exist (which i doubt is true) then someone better get on it and make one Thanks
