问题的描述：\r\na) 用ifconfig 可以看到两个网卡，物理地址及IP正确；\r\nb) 用代码找不到第二块网络接口及其IP。（代码附后）;\r\nc) 用# snoop命令也侦测不到第二个网络接口的收发数据报文；\r\nd) 但即便以上b)、c)，在程序中可以直接对SOCKET绑定第二个接口的IP，仍能够正常收发报文。\r\n说明：之所以想在程序中查询本机接口数及IP，而不直接绑定指定IP，是程序功能要求。因此现在的问题是如何解决以上的问题b)，想请各位高手帮我们查查，另为何用# snoop命令也侦测不到第二个网络接口的收发数据报文。\r\n附：\r\n１．相关的etc下的文件配置：\r\n//--------------------- FILE： path_to_inst \r\n## Caution!
