- Berkeley Packet Filter - Wikipedia
The Berkeley Packet Filter (BPF; also BSD Packet Filter, classic BPF or cBPF) is a network tap and packet filter which permits computer network packets to be captured and filtered at the operating system level

Extended BPF (or eBPF) is similar to the original ("classic") BPF (cBPF) used to filter network packets
- BPF Documentation — The Linux Kernel documentation
This directory contains documentation for the BPF (Berkeley Packet Filter) facility, with a focus on the extended BPF version (eBPF) This kernel side documentation is still work in progress

Berkeley Packet Filters (BPF) provide a powerful tool for intrusion detection analysis Use BPF filtering to quickly reduce large packet captures to a reduced set of results by filtering based on a specific type of traffic Both admin and non-admin users can create BPF filters

What Is A Berkeley Packet Filter (BPF)? A Berkeley Packet Filter (BPF) is a software mechanism that provides a way to capture, filter, and process network packets in real-time Originally developed at the University of California, Berkeley in the 1990s, BPF has become widely used in network analysis, monitoring, and security applications

This page shows examples of performance analysis tools using enhancements to BPF (Berkeley Packet Filter) which were added to the Linux 4 x series kernels, allowing BPF to do much more than just filtering packets

qualifiers specify a particular transfer direction to and or from id Possible directions are src, dst, src or dst and src and dst E g , `src foo', `dst net 128 3', `src or dst port ftp-data' If there is no dir qualifier, src or dst is assumed
