Hi!

We have different computers connected to a router. I want to control the data usage on each computer. I am the admin of the router off course.
I saw that there are different software for Windows.. but i couldnt find anything for (snow)Leopard

Thanx for your help guys!

Read/watch the video at the web site How to track your broadband data usage on PC or Mac (http://reviews.cnet.co.uk/laptops/how-to-track-your-broadband-data-usage-on-pc-or-mac-50006192/). It will point you in the right direction.

what do you mean by "control"? Do you

just want to observe the amount of bandwidth on each computer
really control / limit bandwidth on the computers
