I have created a simple game, that two computer connect together. I have tested on same computer, no problem. When I create ad-hoc network (in Windows 7). One computer is a server, it created successfully :
ssock = new ServerSocket(PORT);
sock = ssock.accept();
And one computer is client:
sock = new Socket("localhost", PORT);
When run to this line. I received this error :
java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:213) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:200) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:529) at java.net.Socket.connect(Socket.java:478) at java.net.Socket.(Socket.java:375) at java.net.Socket.(Socket.java:189) at com.controller.MainController$GameObject.(MainController.java:78) at com.controller.MainController$3.run(MainController.java:180) at java.lang.Thread.run(Thread.java:662)
Please help me point out, what wrong here.
Thanks :)
In the line
sock = new Socket("localhost", PORT);
the first argument "localhost" is the hostname of the machine you want to connect to. "localhost" always means the current machine. When the server runs on another machine, you have to tell the socket where to find it.
You need to replace "localhost" with the IP address or the hostname of the other machine. When you don't know these, follow these steps on the server machine:
cmd and press enter to open the command shellipconfig in the command shell and press enterYou will now see configuration information about all network adapters on the machine, including their IP addresses.
