Hi all,

I was wondering how i would monitor network traffic, like in wireshark.
I have googled and most of the answers are, to use a library like winpcap.
But i dont want to use this method. I want to know what exactly one must do to be able to monitor network traffic at the core, and also with c/c++.
Do I have to use the NIC's driver or is there something I am missing.

Thanks.

Even if you don't want to use winpcap you can have a look on how it works.

You can download the sources at https://www.winpcap.org/devel.htm[^]. A description about the driver internals can be found at http://www.winpcap.org/docs/docs_412/html/group__NPF.html[^].
