通过互联网赢得套接字和通信 [英] Win socket and communication over internet
问题描述
我开发了一个套接字程序，其中有一个聊天服务器和一个客户端。我在我的网络中测试这些应用程序，其中聊天服务器在计算机上运行，客户端正在另一台计算机上运行。当我运行客户端时，我只是给那台机器的IP
，其中聊天服务器正在运行。我的socket客户端可以通过IP与聊天服务器交互。如果我想通过互联网使用这个，那么告诉我如何设置。假设我的聊天服务器将在我们英国办事处的机器上运行，聊天客户端在我们的美国办事处运行
没有任何物理网络。如果我想通过互联网进行沟通，那么我需要做什么。请告诉我这样我可以设置我的聊天应用程序，因此他们可以通过互联网互相交谈.............谢谢。
i have developed a socket program where i have one chat server and one client. i test this apps in my network where chat server is running on a machine and client is running on another machine. when i run client then i just give the IP of that machine where chat server is running. my socket client can interact with chat server through IP. if i want use this over the internet then tell me how could i setup. suppose my chat server would run in a machine of our UK office and chat client run in our USA office there is no any physical network. if i want that communication should occur through internet then what i need to do. please tell me in such way i can setup my chat apps as a result they can talk to each other over the internet.............thanks.
