Ethernet data logger

[Ivoryblade]

I need to find some kind of logger that can act as a middleman on an ethernet line. It just has to store the data that goes through this line onto like, an SD card or something. I'm doing this for a project, but the only ones I've found run $1500 + and have 1000's of options I don't need.

Pretty simple, record all data that runs along ethernet cord and save it. If it needs an external power source, thats fine. But, if the logger can run on batteries, that'd be better.

Any ideas at all would be helpful. I might look into piecing one together myself if need be.

I think what you need is a "packet sniffer". If so, ethereal is free and it is available for various operating systems. Check out the features here: http://www.ethereal.com/introduction.html

Do you need the actual data, or just a report of what's happening on the data lines?

As said above, a packet sniffer is probably what you need. They can output some really good reports about what exactly went on.

I'd like the actual data if possible.

a "project" huh? like snooping on your friends IM conversations or something? ahaha


anyways, just put a hub in between your wifes/girlfriends/roomates computer, plug in your computer with the packet sniffer (ethereal rocks), and start capturing!
