Yet Another Flow Sensor

YAF is Yet Another Flow sensor. It processes packet data from pcap(3) dumpfiles as generated by tcpdump(1) or via live capture from an interface using pcap(3) or an Endace DAG card into bidirectional flows, then exports those flows to IPFIX Collecting Processes or in an IPFIX-based file format. YAF's output can be used with the SiLK tools, yafscii, and super_mediator.
