在 Python 中选择多播网络接口 [英] Choosing multicast network interface in Python

问题描述

我有一台带有两个独立以太网连接的服务器.当我在 python 中绑定一个套接字时，它默认为两个网络之一.如何从 Python 中的第二个网络中提取多播流?我曾尝试在第二个网络上使用服务器的 IP 地址调用 bind，但没有奏效.

I have a server with two separate Ethernet connections. When I bind a socket in python it defaults to one of the two networks. How do I pull a multicast stream from the second network in Python? I have tried calling bind using the server's IP address on the second network, but that hasn't worked.

推荐答案

我想通了.事实证明，我缺少的部分是将接口添加到用于向多播组添加成员资格的 mreq 结构中.

I figured it out. It turns out that the piece I was missing was adding the interface to the mreq structure that is used in adding membership to a multicast group.
