示例:
绑定igb_uio(mlx4/mlx5无需绑定)后
./pktgen -c 0xffff --socket-mem=5120,5120 -w 03:00.0 -w 03:00.1 -n 2 -r 2 -- --crc-strip -P -m [1:2-15].0 -T -N
注意事项
1. pktgen 支持单一、范围、随机、序列多重数据流发送模式，每种模式都拥有自己的packet buffer。所以为每种模式启用不同的配置，并启用模式(enable port-id mode)，默认启用为单一数据流放方式;
2. pktgen 最小要求2个CPU才可以运行，0核用于处理命令行&计时器屏幕刷新，其他核用于发送&接收数据报文；
3. pktgen一定要在与pktgen.lua文件同一目录下运行，即pktgen的文件夹中运行;

本人最近在学习使用Pktgen构造DDoS的攻击流，就记录了一下Pktgen和DPDK的使用学习笔记
dpdk是Intel发起的高速网络处理工具，能够旁路Linux在用户空间接管CPU、内存和网卡队列，进行高度并行的网络收发包。pktgen-dpdk是Linux内核发包工具的dpdk加强版
一、安装配置
安装过程需要设置hugepage以支持dpdk，编译加载dpdk模块和绑定网卡，编译pktgen-dpdk，运行pktgen-dpdk.
安装 dpdk-20.11，可以参看dpdk-20.11 编译和安装
dpdk-pktgen 有独立的 git 仓库，并且可以基于 meson 和 ninja 进行构建，因此安装过程很简单。
安装过程如下：
$ git clone git://dpdk.org/apps/pktgen-dpdk
$ cd pktgen-dpdk
$ git checkout ma...

上一篇通过在虚拟机中安装dpdk和pktgen，基本已经有了一个可以测试的环境，今天主要验证pktgen的-s选项，通过pcap格式的数据文件来构造pktgen端口发送的数据，这个功能实在是太有效果了，可惜的是家里的环境没有那么多网卡，没办法捕获到pktgen端口发出的消息，否则看起来会更加直观。
在贴图之前，先简要记录一...
Pktgen, (Packet Gen-erator) is a software based traffic generator powered by the DPDK fast
packet processing framework.
Some of the features of Pktgen are:
• It is capable of generating 10Gbit wire rate traffic with 64 byte frames.
• It can act as a transmitter or receiver at line rate.
• It has a runtime environment to configure, and start and stop traffic flows.
• It can display real time metrics for a number of ports.
• It can generate packets in sequence by iterating source or destination MAC, IP addresses
or ports.
• It can handle packets with UDP, TCP, ARP, ICMP, GRE, MPLS and Queue-in-Queue.
• It can be controlled remotely over a TCP connection.
• It is configurable via Lua and can run command scripts to set up repeatable test cases.
• The software is fully available under a BSD licence.
错误如下EAL: VFIO support initialized
EAL: Probe PCI driver: mlx5_pci (15b3:101e) device: 0000:12:01.0 (socket 0)
mlx5_pci: no Verbs device matches PCI device 0000:12:01.0, are kernel drivers loaded?
