Berkeley Packet Filter: History, Filtering & Overview

The Berkeley Packet Filter (BPF; also BSD Packet Filter, classic BPF or cBPF) is a network tap mechanism and packet filter which permits computer network packets to be captured and filtered at the operating system level. It provides a raw interface to data link layers, permitting raw link-layer packets to be sent and received, and allows a userspace…
