A nice Network Management Tool
I use MRTG for monitoring and graphing many of the devices on my personal network, and also on our 80211.net wireless network. MRTG is a very simple, yet powerful application. I happened to come across this project the other day, and we’re about to give it a test. It appears to be a very good extension of the capabilities of MRTG without getting too complex.
