如果客户端和服务器在不同的网络上，那么他们可以使用套接字编程相互通信？ [英] if client and server are on different network then they can communicate with each other using socket programming?

问题描述

我想知道在套接字编程客户端和服务器可以相互通信，如果两者都在不同的网络位置..像一个skype信使..

e.g i just want to send "hello string " from clients and recieve its on server then after response back to clients that "server recieved your message" ..

推荐答案

要向某人发送消息，您需要能够要到达目的地地址，如果您在不同的本地网络之间发送，而您之间没有桥接器/路由器则无法发送。



To看看是否可以尝试：

To send a message to someone you need to be able to reach the destination address, if you are sending between different local networks and you don't have a bridge/router in between then you can't send.

To see if it is possible try :

c:\>ping <your destination="" ip=""></your>

如果它不起作用则无法发送。

If it does not work then you can't send.

这与您的编码无关，而且与您的网络配置和防火墙有关。如果您无法在客户端和服务器之间执行ping操作，则这两个点之间没有打开的路由。如果这是您的网络，则需要检查防火墙设置以及路由表。如果这是其他人的网络，那么您需要向他们寻求帮助。

This has nothing to do with your coding, and everything to do with your network configuration and firewall. If you cannot ping between client and server then there is no open route between those two points. If this is your network then you need to check the firewall settings and also the routing tables. If this is someone else's network then you need to ask them for assistance.
