[Click] Read data from a real IP address

[Jimmy]

Hi all,

Is it possible to read packets data from a real IP address using user level?

So FromDevice.u reads packets from the kernel that were received on
the network controller named DEVNAME, but if I want to read data from
a specific IP address, how to do that?

How can I identify my own computer's network controller name?

Thanks a lot.

J.
