Webbpf -- Berkeley Packet Filter SYNOPSIS. device bpf DESCRIPTION. The Berkeley Packet Filter provides a raw interface to data link layers in a protocol independent fashion. All packets on the network, even those destined for other hosts, are accessible through this mechanism. The packet filter appears as a character special device, /dev/bpf. The Berkeley Packet Filter (BPF) is a technology used in certain computer operating systems for programs that need to, among other things, analyze network traffic. It provides a raw interface to data link layers, permitting raw link-layer packets to be sent and received. In addition, if the driver for the network … See more BPF provides pseudo-devices that can be bound to a network interface; reads from the device will read buffers full of packets received on the network interface, and writes to the device will inject packets on the network interface. See more Classic BPF is generally emitted by a program from some very high-level textual rule describing the pattern to match. One such representation is found in libpcap.
