nTop and all network monitors can only report on the traffic they see. If you install it on your workstation, you'll only see traffic to and from your workstation unless you use some other components to ... "replicate" traffic to/from the other workstations to your workstation.
If you want to see traffic from both systems in real-time AND without any wires - that could be tricky. Adding some sort of fixed desktop system (*nix) running nTop would be best. nTop can also read files as input, so you could install Ethereal or similar on each system and configure it to capture only the headers of the packets to save on disk space requirements and overhead. Then you can feed these all to your system and process with nTop for reports. Bottom line is to see traffic to/from a host, you need a probe somewhere that can physically see those frames/packets - which means a probe on each host or a probe(s) on the gateways, routers, firewalls, etc - the access points to/from your network. I've heard of people "hacking" LinkSys routers to make them support netflow. This might be an option for you. Netflow processes run on the gateway and count the traffic and send this to the nTop system. Since it's only counts of the traffic flows is very light weight compared to full packet captures.

I want to monitor the traffic in my wireless network to see where the traffic is going to. So I installed ntop on my computer (not the router or gatewy - simple workstation) but I only see the traffic from ny computer and not from the other computer in the network (unless it is connecting to my computer). Is there any way that I can set ntop up to monitpor the traffic from the other computer as well? Theya are both laptops, so the setup needs to be flexible and I can not use the one computer as a gateway. My setup: two laptops and one DG834gt netgear ADSL router. Thanks, Rainer -- Rainer M.
