   A server example _does_ exist at [SshServerMain](https://github.com/apache/mina-sshd/blob/master/sshd-cli/src/main/java/org/apache/sshd/cli/server/SshServerMain.java). Note that it is insecure: it allows any password log-in where the password equals the user name given, and it accepts any public key.
   
   If you want it even simpler: here's a quick'n'dirty hack I sometimes use for testing:
   ```
   import java.nio.file.Paths;
   import java.time.Duration;
   
   import org.apache.sshd.common.session.SessionHeartbeatController;
   import org.apache.sshd.server.SshServer;
   import org.apache.sshd.server.forward.AcceptAllForwardingFilter;
   import org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider;
   import org.apache.sshd.server.shell.InteractiveProcessShellFactory;
   
   public class TestServer {
   
       public static void main(String[] args) throws Exception {
           SshServer sshd = SshServer.setUpDefaultServer();
           sshd.setPort(12133);
           SimpleGeneratorHostKeyProvider hostKeys = new SimpleGeneratorHostKeyProvider(Paths.get("/tmp/a.ser"));
           sshd.setShellFactory(InteractiveProcessShellFactory.INSTANCE);
           sshd.setSessionHeartbeat(SessionHeartbeatController.HeartbeatType.IGNORE, Duration.ofSeconds(5));
           sshd.setKeyPairProvider(hostKeys);
           hostKeys.loadKeys(null);
           sshd.setPasswordAuthenticator((username, password, session) -> true);
           sshd.setPublickeyAuthenticator((username, pubkey, session) -> true);
           sshd.setForwardingFilter(AcceptAllForwardingFilter.INSTANCE);
           sshd.start();
           Thread.sleep(10000000);
       }
   }
   ```
   Listens on port 12133 and allows any password or public key.
