A little problem about an idea, help please

Hello there, Thank you for taking the time to read this, i H ave a problem about a program I have to make for school and I have no Idea on how to do it, so any help could come useful:

I have to make a program to get the IP direction of someone who is either sending me or receiving a file from me, for example if I am connected to Imesh, the program should track all directions of the people who are sending files to me and receiving files, ad to display them on screen.

I actually am in real trouble about that, because I have no Idea on how to track someone by the packs that are being sent, so if someone ther could help me I would be truly thankful

thank you

well you could be cheap and go

Code:

---

system("netstat");

---

:)

EDIT: I do not actually suggest this,
Is this a Win32 program?

Well I don't know about writing this, but you could always download a packet sniffer like ethereal. I'm not entirely sure why you need to do this anyway though...

Edit: Oh sorry I didn't see that you had to make it. My bad

I can't really help you here, except to suggest looking at the resources on the network programming board

Well depending on the platform, there might be api functions that you can use.
