You mention to see data in = real time. For this trafshow is nice to have. For more information and a = heavier load you could look at ntop. It provides a great deal of = information. There is also the ability to log IPFW which could also be = used to provide you with some detail. Another possibility is bandwidthd. As mentioned trafshow does show the traffic in real time and is = light-weight and very easy to use. I Ntop runs it's on web server and provides a much greater depth of detail = than what you have mentioned here. Bandwidthd provides graphs (similar to MRTG but monitors each ip address = on the router individually!!) for the hosts it is configured to monitor. = HTH, Lewis Watson
