wms listen interface问题 #38

Closed unissoft-bj closed 9 years ago

unissoft-bj commented 9 years ago

wms部署到ihost上时，read stream time out.

ihost上的interfaces：

其中的eth0/tun0分别相当于wan口和lan口。但是因为ihost上只有一个物理网口，所以实际上tun0是虚拟出来的，与eth0是一个物理网口

在eth0上抓包，能抓到语音udp包 在tun0上抓包，抓不到语音udp包（即使接通client端的internet，也抓不到udp包）。如果wms listen tun0的话，得不到udp包。

wms需要从eth0上获取udp包，而不是tun0

对比：不启动chilli

eth0:10对应的是上面的tun0，但二者的工作模式有区别。tun0仅允许流控的包 此时在eth0上抓包，和在eth0:10上抓包，效果是一样的。wms能正常保存语音文件到/wms/audio
