Per-user bandwidth monitoring tool for linux-based routers

What is it ? A small shell script designed to run on linux powered routers (OpenWRT, DD-WRT, Tomato, and other routers where shell access is available). It provides per user bandwidth monitoring capabilities and generates usage reports. How do I use it ? Please have a look at this wiki page : http://code.google.com/p/wrtbwmon/wiki/Deploying Alternatives wrtbwmon is not actively developed anymore. I invite you to consider these alternative projects : 1. The tomatousb guys have done an awesome job at integrating its functionality into the tomato firmware and have taken it way beyond anything I could have dreamed of. Look for the IP traffic monitoring features in Toastman, Shibby or Teaman late
