pcap flow generation utility

generate ranodmized pcap data based on netflow topology. e.g. this generates X number of unique 5 tupple IPv4 TCP/UDP flows.

Primary usage for load testing capture and analytics systems

Options:
-v                 : verbose output

--pktcnt   <total packts>        : total number of packets to output
--flowcnt  <total flows>         : total number of flows
--pktsize  <packet size>         : size of each packet
--pktslice <packet slice amount> : packet slicing amount (default 0)
--bps      <bits output rate>    : output generation rate (e.g. 1e9 = 1Gbps)


Generate PCAP from histogram example:
./pcap_genflow --histogram <path>/histograms.bin > test.pcap

Convert binary histogram to text histogram example:
./pcap_genflow --histogram-bin2txt <path>/histograms.bin > test.txt
