我正在尝试将数据包从我的 pcap 文件发送到我的树莓派。我在 Windows 笔记本电脑上使用 WSL2 盒通过 wifi 发送数据包。
WSL2 可以 ping 通树莓派
--- 192.168.1.79 ping statistics ---
240 packets transmitted, 239 received, 0.416667% packet loss, time 239444ms
rtt min/avg/max/mdev = 3.469/38.258/621.335/103.481 ms
Wireshark 确认：
但是当我运行 tcpreplay 时
sudo tcpreplay -i eth0 -K /home/barry/pcaps/HomeWifi.pcap
我在 Wireshark 上没有得到任何输出。尽管有 WSL2 输出，Pi 仍没有收到数据包：
$ sudo tcpreplay -i eth0 -K HomeWifi.pcap

我很困惑为什么 ping 有效，但 tcpreplay 却不起作用。有解决办法吗？
