If you want to monitor and manage your Internet bandwidth, perhaps to make sure your ISP is not overbilling you, try vnStat, an open source, Linux-based application that gives you a clear picture of your bandwidth usage. This command-line application is simple to install and easy to use.

Good tool for the comcast users that are getting shutdown by their isp,Baldy
