Hi I am an ISP running FreeBSD as a firewall and as a Mail Server. My problem is that I am not able to monitor the amount of traffic that user are using on my network. in south Africa bandwidth is extremely expensive and I need to take my bandwidth to the edge. My network looks like this: My Link comes in on a Cisco 805 from the router it goes to the first NIC on the Firewall from the second NIC it runs into a 10base HUB where there are only 3 ports used one as I said for the Firewall the other for a FreeBSD box (I want to use this box for traffic monitoring) and then one port for the rest of the network which connects to a 100base switch. The reason I used the 10base HUB is because it broadcasts all the data to all the ports. So for all data to and from the firewall will be caught by the Monitoring BSD box. I hope this makes sense. What I am looking for is some app that could show me live what ip on my network is utilizing what part of the bandwidth. Don't laugh !!I have a 256k Diginet connection and I would like to see who is killing my network. I do get live graphs from my upstream supplier but it shows the line utilization from my router and not who is using what. So I can't be proactive in solving speed issues I need to wait for it to happen and then by a process of elimination disconnect segments of the network and see when the graph drops. I tried TCPDUMP but it is difficult to understand (perhaps I am just stupid) but it's a time consuming process and to late to fix the problem. I hope this makes sense to someone thank you Spidey
