java.io.IOException：在 MacOS X Snow Leopard 上没有使用 MulticastSocket 到主机的路由
我有一个使用多播的 java 应用程序来宣传某些实体 - 当我几周前尝试该应用程序时，一切都工作正常。但是，情况不再是这样：
java.io.IOException: No route to host
当未更改的应用程序再次启动时，我收到异常。应用程序正在将 DatagramPackets 发送到 224.0.0.1。
我当前的系统是 Mac OS X Snow Leopard (10.6.7)，安装了 Java 1.6.0_24。
我尝试了多种方法，得到了以下结果： - 谷歌搜索 ->一些建议，到目前为止没有任何帮助 - 禁用防火墙->不成功 - 禁用网络接口（强制其使用环回）->不成功 - 在 Win 机器上运行 ->成功，所以我认为它肯定与当前（或更改/更新）的系统配置有关
任何指针或建议都非常感谢！
干杯
I have a java application using multicast in order to advertise some entity - all worked fine when I tried the application a couple of weeks back. However, this is not the case anymore: I'm getting a
java.io.IOException: No route to host
exception when the unchanged application is started again. The application is sending DatagramPackets to 224.0.0.1.
My current system is Mac OS X Snow Leopard (10.6.7) with Java 1.6.0_24 installed.
I've tried out several approaches with the following outcomes:
- search google -> some suggestions, none of which helped so far
- disable firewall -> not successful
- disable network interface (to force it to use the loopback) -> not successful
- running it on Win machine -> successful, so I assume it definitely has something to do with the current (or changed/updated) system configuration
Any pointers or suggestions are greatly appreciated!
Cheers

没有到主机的路由是由于您的进程从您和目标 IP 之间的路径上的某个路由器接收到 ICMP“主机无法访问”消息而导致的。由于您是在多播地址上获得此信息，因此我怀疑您的路由器配置有问题。No route to hostis caused by your process receiving an ICMP "host unreachable" message from some router on the path between you and the destination IP. Since you're getting this on a multicast address, I'd suspect something wrong with your router configuration.
