尝试创建SSL客户端套接字时，CLOSE_WAIT和FIN_WAIT_2

Question

The server port was listening correctly before I invoked this line:

SSLSocket socket = (SSLSocket) ssFactory.createSocket(ipAddress, port);

Then it became like this:

1. TCP 0.0.0.0:23333 0.0.0.0:0 LISTENING
2. TCP 10.200.49.196:23333 10.200.49.196:50814 FIN_WAIT_2
3. TCP 10.200.49.196:50814 10.200.49.196:23333 CLOSE_WAIT

I never wanted to close the port. Why did it hang like that? The code worked fine before.

Answer 1

I can not ask as comment. :(

Did the certificate change and the SSL hand shake failed? This may result in a closed SSL connection.

The netstat output shows:

• a running server socket
• a client to server entry of a closed connection
• and a server to client entry of a closed connection

Is there any exception thrown?
