如何列出LAN上无身份验证的可用SMB服务器(Java)

import java.io.IOException;
import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.ArrayList;
import java.util.List;

public class SMBServerScanner {

    public static void main(String[] args) {
        List<String> availableServers = scanSMBServers();
        System.out.println("Available SMB Servers:");
        for (String server : availableServers) {
            System.out.println(server);
        }
    }

    public static List<String> scanSMBServers() {
        List<String> availableServers = new ArrayList<>();

        try {
            InetAddress[] addresses = InetAddress.getAllByName("255.255.255.255");
            for (InetAddress address : addresses) {
                if (address.isReachable(1000)) {
                    availableServers.add(address.getHostAddress());
                }
            }
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return availableServers;
    }
}
