[tcpreplay] tcpreplay高级用法--使用tcpreplay-edit进行循环动态发包

tcpreplay-edit提供了可对包进行修改的高级用法：

      --unique-ip

              Modify IP addresses each loop iteration to generate unique flows.  This option must appear in combination with the following options: loop.  This option must not appear

              in combination with any of the following options: seed, fuzz-seed.

              Ensure IPv4 and IPv6 packets will be unique for each --loop iteration.  This is done in a way that will not alter packet CRC, and therefore will genrally not affect per‐

              formance. This option will significantly increase the flows/sec over generated over multiple loop iterations.

       --unique-ip-loops=string

              Number of times to loop before assigning new unique ip.  This option may appear up to  times.  This option must appear in combination with the following options: unique-

              ip.

              Number of --loop iterations before a new unique IP is assigned. Default is . Assumes both --loop and --unique-ip.

原包如下：

┬─[tong@T7:~/Data]─[:: AM]

╰─>$ sudo tcpreplay-edit -i replay-br0 -t baidu.pcap

收包如下：

[root@dpdk ~]# tcpdump -i eth1 -nn "tcp[tcpflags] & (tcp-syn) != 0 and tcp[tcpflags] & (tcp-ack) == 0"

::17.125017 IP 192.168.10.56. > 202.89.233.103.: Flags [S], seq , win , options [mss ,sackOK,TS val  ecr ,nop,wscale ], length

::17.125093 IP 192.168.10.56. > 203.208.39.205.: Flags [S], seq , win , options [mss ,sackOK,TS val  ecr ,nop,wscale ], length

::17.125124 IP 192.168.10.56. > 120.25.241.229.: Flags [S], seq , win , options [mss ,sackOK,TS val  ecr ,nop,wscale ], length

::17.125133 IP 192.168.10.56. > 114.55.49.182.: Flags [S], seq , win , options [mss ,sackOK,TS val  ecr ,nop,wscale ], length

使用，--uique-ip 参数可以在保证flow关系的前提下修改IP，修改策略是，源IP地址加一，目的IP地址减一

发包如下：

┬─[tong@T7:~/Data]─[:: AM]

╰─>$ sudo tcpreplay-edit -i replay-br0 -t --unique-ip -l3 baidu.pcap

收包如下：

[root@dpdk ~]# tcpdump -i eth1 -nn "tcp[tcpflags] & (tcp-syn) != 0 and tcp[tcpflags] & (tcp-ack) == 0"   

::31.745157 IP 192.168.10.56. > 202.89.233.103.: Flags [S], seq , win , options [mss ,sackOK,TS val  ecr ,nop,wscale ], length

::31.745292 IP 192.168.10.57. > 114.55.49.181.: Flags [S], seq , win , options [mss ,sackOK,TS val  ecr ,nop,wscale ], length

::31.745395 IP 192.168.10.54. > 203.208.39.207.: Flags [S], seq , win , options [mss ,sackOK,TS val  ecr ,nop,wscale ], length

再增加 --unique-ip-loops=3 参数，可以增加策略复杂性，效果就是，第2次loop和第3次loop的包，与第一次loop重复，例子如下：

发包：

┬─[tong@T7:~/Data]─[:: AM]

╰─>$ sudo tcpreplay-edit -i replay-br0 -t --unique-ip --unique-ip-loops= -l9 baidu.pcap

收包：
