저도 똑같네요 read 할땐 에러가 안나오고 정상적으로 출력되고write 할땐 예제처럼 Broken pipe 가 터집니다.자바 버전은 21 쓰는데 자바 버전 11, 17, 21 다 해봤는데 같았구요 OS는 Ubuntu 20.04.6 LTS 사용하고 있어요&nbsp;<pre><code class="language-java">package network.exception.close.reset;

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

import static util.MyLogger.log;

public class ResetCloseServer {

 public static void main(String[] args) throws IOException {
 ServerSocket serverSocket = new ServerSocket(12345);
 Socket socket = serverSocket.accept();
 log("Socket accepted: " + socket);

 socket.close();
 serverSocket.close();
 log("Socket and serverSocket closed");
 }

}</code></pre>&nbsp;&nbsp;<pre><code class="language-java">package network.exception.close.reset;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.Socket;
import java.net.SocketException;

import static util.MyLogger.log;

public class ResetCloseClient {

 public static void main(String[] args) throws IOException, InterruptedException {
 Socket socket = new Socket("localhost", 12345);
 log("Socket connected: " + socket);
 InputStream input = socket.getInputStream();
 OutputStream output = socket.getOutputStream();

 // client <- server : FIN
 Thread.sleep(1000); // wait until server calls close();

 // client -> server : PUSH[1]
 output.write(1);

 // client <- server : RST
 Thread.sleep(1000); // waits for RST message sending

 try {
// java.net.SocketException: Connection reset
 int read = input.read();
 System.out.println("read = " + read);
//
// output.write(0);
 } catch (SocketException e) {
 e.printStackTrace();
 }
 }

}
</code></pre>

SocketException: Connection reset 에러가 뜨지 않습니다

내부아이피 쓰는것도 한 방법이지만, 연결된 네트웍 상황에 따라 달라질 수 있으니 host.docker.internal 한번 이용해보세요<code>http://host.docker.internal:9090</code>필요할 경우 참고하실 링크 하나 남겨둘게요<a target="_blank" rel="noopener noreferrer nofollow" href="https://shanepark.tistory.com/209">https://shanepark.tistory.com/209</a>
