node.js - Socket.io 在某些机器上无法工作

Question

我从 Socket.io 开始，我制作了一个快速示例应用程序，大多数事情似乎都正常。然而，当我在办公室的另一台电脑上测试它时，它不起作用。我无法确定问题或共同点。它可以在运行 Chrome 和 Firefox 的 iMac 以及运行 Firefox 15.0.1 的 Windows 计算机上运行。

但是在另外 2 台机器上它不起作用，它们运行 Firefox 15.0.1 和最新的 Chrome。他们可以连接并接收广播，但不会发送任何广播。

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。所有计算机共享相同的 IP 地址，这会是问题吗？

谢谢。

我部分解决了这个问题。防病毒程序阻止了一些计算机上的 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/显示所有端口均已打开，并且软件显示没有事件的防火墙。然而，当退出防病毒程序时，一切又开始工作。

不知道为什么 http://websocketstest.com/显示所有端口均已打开。暂时切换到843端口。

谢谢
