## 捕包
``` shell
/opt/tsg/mrzcpd/bin/mrpdump -- --pdump "dev_name=nf_0_fw,queue=*" --bpf-rule="host 192.0.2.110 and port 80" --dumpfile-path=/home/admin/fw.pcap
tcpdump -i virtio_dign_c host 192.0.2.110 and port 80 -n -v -w virtio_dign_c.pcap
tcpdump -i virtio_dign_s host 192.0.2.110 and port 80 -n -v -w virtio_dign_s.pcap
```
## 运行
``` shell
./packet_injector -t tcp-rst -c c2s-packet -n 1 # After recv SYN
./packet_injector -t tcp-rst -c s2c-packet -n 1 # After recv SYN-ACK
./packet_injector -t tcp-rst -c c2s-packet -n 2 # After recv Sub-ACK
./packet_injector -t tcp-rst -c c2s-packet -n 3 # After recv First-Payload
```
``` shell
./packet_injector -t tcp-fin -c c2s-packet -n 1 # After recv SYN
./packet_injector -t tcp-fin -c s2c-packet -n 1 # After recv SYN-ACK
./packet_injector -t tcp-fin -c c2s-packet -n 2 # After recv Sub-ACK
./packet_injector -t tcp-fin -c c2s-packet -n 3 # After recv First-Payload
