libpcap Library - Linux User-space Network Stack Development
libpcap Library - Linux User-space Network Stack Development

libpcap is a very popular user-space networking library, with which you can capture and or generate packets. libpcap is the underlying framework for many popular packet capture tools such as tcpdump, Wireshark and so on. In fact libpcap is a part of tcpdump project. But besides just using it as a packet capture tool, you can use libpcap in various applications, such as user-space based networking stack development, etc. In some cases libpcap is yet another alternative to raw-sockets and tun/tap interfaces.

Here is my detailed multi-episode YouTube video series on libpcap Library with a sample libpcap C code.

Download this episode my entire kernel module sample code, make file, clean script which I hosted in my GitHub Repo.

I also conduct sessions/classes on Systems and Network Software Programming, Linux Kernel Programming and Architecture. If you are interested, click HERE for more details.
