| What does "IP_ADD_MEMBERSHIP: No such device" mean? It means that the tool is trying to use multicast but the network interface doesn't support it There are two likely causes: ·Your machine doesn't have multicast support enabled. For example, on Linux and FreeBSD it is possible to compile a kernel which doesn't support multicast. ·You don't have a route for multicast traffic. Some systems don't add this by default, and you need to run: route add -net 224.0.0.0 netmask 224.0.0.0 eth0(or similar). If you wish to use RAT in unicast mode only, it is possible to add the multicast route on the loopback interface. |
出现上诉问题的两种可能:
1.你的机器没有可用的组播功能(在ubuntu下通过ifconfig检查虚拟机是否支持本功能)。
2.没有为主机添加路由,有些系统不添加默认情况。你需要在终端下输入:route add -net 224.0.0.0 netmask 224.0.0.0 eth0(or similar).
本文详细解释了IP_ADD_MEMBERSHIP:Nosuchdevice错误的含义,指出这通常意味着尝试使用组播功能但网络接口不支持此功能。问题可能源于机器未启用组播功能或缺少针对组播流量的路由设置。文中提供了排查步骤及解决方案,包括检查虚拟机组播支持、为主机添加组播路由。
