Java - 無法連接ServerSocket

Question

我正在嘗試使用端口2649的ServerSocket，而其他人無法連​​接。它可以與localhost正常工作。這是錯誤試圖連接當人們：

Exception in thread "main" java.net.ConnectException: Connection timed out: connect 
at java.net.TwoStacksPlainSocketImpl.socketConnect(Native Method) 
at java.net.AbstractPlainSocketImpl.doConnect(Unknown Source) 
at java.net.AbstractPlainSocketImpl.connectToAddress(Unknown Source) 
at java.net.AbstractPlainSocketImpl.connect(Unknown Source) 
at java.net.PlainSocketImpl.connect(Unknown Source)

at java.net.Socket.connect(Unknown Source) 
at java.net.Socket.<init>(Unknown Source) 
at java.net.Socket.<init>(Unknown Source) 
at Client.main(Client.java:11) 

我有端口轉發，我沒有在我的電腦上主動防火牆。以下是端口轉發時使用的設置。

當我檢查端口2649上canyouseeme.org，它說，連接超時。

我也使用Windows XP。任何幫助表示讚賞。

感謝

Answer 1

如果不是防火牆的代碼。確保你將服務器套接字綁定到0.0.0.0而不是localhost。嘗試調用server.bind（new InetSocketAddress（「0.0.0.0」，port））;

Answer 2

「連接超時」 - >防火牆丟棄數據包。最有可能的Windows防火牆 - 嘗試禁用它，看看他們是否可以連接。
