我正在为网络交换机的 IGMP 和 MLD 实现编写测试用例。这些测试用例在 Raspbian 上运行。但是，Raspbian 似乎会定期发送自己的 IGMP 报告/查询，这会干扰我的测试用例。我如何全局或针对给定接口禁用这些数据包？
我见过这个答案，但无法确定哪个进程生成了 IGMP 流量。据我所知，我没有安装任何需要多播组的应用程序。
因为我需要使用 Scapy 发送和接收 IGMP 来进行测试用例，所以仅在防火墙中阻止 IGMP 不是一个选择。
以下是有问题的流量：
pi@raspberrypi204:~ $ sudo tshark -i any -Y igmp
tshark: Lua: Error during loading:
[string "/usr/share/wireshark/init.lua"]:46: dofile has been disabled due to running Wireshark as superuser. See http://wiki.wireshark.org/CaptureSetup/CapturePrivileges for help in running Wireshark as an unprivileged user.
Running as user "root" and group "root". This could be dangerous.
