Question

我开始使用Socket.io，我做了一个快速的示例应用程序，大多数事情似乎都在起作用。但是，当我在办公室的另一台PC上测试它时，它不起作用。我无法确定问题或共同的因素。它适用于chrome和firefox中的iMac，以及运行Firefox 15.0.1的Windows机器。

然而，在其他2台机器上它不起作用，它们运行Firefox 15.0.1和最新的chrome。他们可以连接和接收广播，但他们不会发送任何广播。

随socket.io提供的示例应用程序面临同样的问题，所以我知道我的代码不是问题。

服务器是机架空间虚拟机。这些计算机都共享相同的IP地址，这会是问题吗？

感谢。

我部分解决了这个问题。一个反病毒程序阻止了几台机器上的Web套接字连接。我花了一段时间才发现这个问题，因为http://websocketstest.com/显示所有端口都处于打开状态，并且软件显示没有防火墙处于活动状态。但是，退出防病毒程序时，一切都开始工作了。

不知道为什么http://websocketstest.com/显示所有端口都已打开。现在切换到843端口。

由于

Socket.io无法在某些机器上运行
