Bandwidth Monitoring over Local Network

I've been trying to find an application that will let me monitor how much of my DSL bandwidth is being used up by computers on the home network, by IP. I live in a share house and it would be useful to be able to identify usage via a more scientific method than unplugging people one by one!

I've tried searching this forum & online to no avail, is anyone familiar with this sort of software and give me advice? I've downloaded Wireshark but I couldn't get it to give me the results I need.

If anywhere, the software would have to be on a router, or any other machine which sat between your internet connection and the rest of your network.

Unfortunately, you probably will need a managed switch to do this, and those aren't cheap.

Could you find your packet request logs on your router and tally up IPs by hand, or write a quick program to do it for you?

Install bwmon on router? (Assuming you have a linux-flashable router)

I have the same issue. I was playing with netmeter, the problem there is that it needs to run client side and can't differentiate between LAN and internet traffic.

My netgear FS726T does this, and it is cheap for a managed switch.

It also has other nice stuff like vlan and so on.

Port 26 is incomming internet
Port 25 internet to firewall
Port 24 is firewall to lan
Port 1 is IP TV
The rest is my lan.

This image might be better to describe it.

I endorse this solution.

Well, we will soon have a spare... it might be viable.
