Introduction

In this tutorial we learn how to install libpcap on Fedora 34.

What is `libpcap`

Libpcap provides a portable framework for low-level network monitoring. Libpcap can provide network statistics collection, security monitoring and network debugging. Since almost every system vendor provides a different interface for packet capture, the libpcap authors created this system-independent API to ease in porting and to alleviate the need for several system-dependent packet capture modules in each application. Install libpcap if you need to do low-level network traffic monitoring on your network. libpcap 14 1.10.1 1.fc34 x86_64 171 k libpcap-1.10.1-1.fc34.src.rpm updates A system-independent interface for user-level packet capture https BSD with advertising Libpcap provides a portable framework for low-level network monitoring.
