monitering internet traffic on network

[Hellotalkie]

Right now i have a wireless network with 4 pc's. I just wanted to knw if there is a program to moniter one computers internet traffic. All of the computers have xp on it. Also for the program to be free would be great, and if the product would have a performance moniter built in that would also be great but not really needed. Just need the internet traffic software.

What type of router do you have?

http://www.ethereal.com/ and and put the computer you want to monitor and the monitoring computer into the hub, then hub to router



didnt see wireless but you could still use ethereal i think there is a wireless plugin if you have the right wireless card

You can monitor the bandwidth on each individual computer by using the NetSstat

NetStat Live.

Entry Level Routers cannot monitor centrally.

To monitor Centrally you need a professional Managed Router (they are very expensive).

Alternatively, get rid of the Entry Level Router and build a Linux Box to act as a Router.

Or Use Windows 2003 as a Server Router.

If you want to Limit the usage.

You can use Qos available with flashable (v.1 -4) Linksys WRT54g with 3rd party firmware. (

In general, Can I Monitor my LAN, control the usage of the Internet, and Network Resources by other computers from my main computer?

you need to create a tap into the network.

For wireless sniffing (packet level stuff) airopeek works, but is very buggy for some things

if you are looking for "general" stuff, setup a router as an access point and bridge the ap to the router using an old school hub, then plug in a linux box and run ethereal, ntop, snort, or one of any number of programs. Ntop is pretty easy to setup on Debian (I have several) and gives a good "overall" feel for the network, but it's hardware hungry.
