- 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
- bpf (2) - Linux manual page - man7. org
Extended BPF (or eBPF) is similar to the original ("classic") BPF (cBPF) used to filter network packets
- Berkeley packet filters - IBM
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
- Linux Extended BPF (eBPF) Tracing Tools - Brendan Gregg
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
- Understanding of BPF - Unix Linux Stack Exchange
BPF (or more commonly, the extended version, eBPF) is a language that was originally used exclusively for filtering packets, but it is capable of quite a lot more
- Linux Socket Filtering aka Berkeley Packet Filter (BPF)
Linux Socket Filtering (LSF) is derived from the Berkeley Packet Filter Though there are some distinct differences between the BSD and Linux Kernel filtering, but when we speak of BPF or LSF in Linux context, we mean the very same mechanism of filtering in the Linux kernel
- Filter packets with Berkeley Packet Filter syntax - ExtraHop
Berkeley Packet Filters are a raw interface to data link layers and are a powerful tool for intrusion detection analysis The BPF syntax enables users to write filters that quickly drill down on specific packets to see the essential information
- BPF syntax - biot. com
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
