Deteksi port dengan Python (dengan soket paket):

import socket


def port_checker(ip_address_or_domain, port_number):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    try:
        sock.connect((str(ip_address_or_domain), int(port_number)))
        return "PORT {0} is OPEN on '{1}'.".format(port_number, ip_address_or_domain)
    except Exception as e:
        print(str(e))
        return "PORT {0} is CLOSED on '{1}'.".format(port_number, ip_address_or_domain)
    finally:
        sock.close()

Deteksi port di Jawa (dengan paket java.net.Socket):

    public static boolean check_port(String ip_or_domain, int port) {
        try (Socket server = new Socket(ip_or_domain, port)) {
            System.out.println("Port " + port + " is OPEN on " + ip_or_domain);
            return true;
        } catch (IOException ignored) {
            System.out.println("Port " + port + " is CLOSED on " + ip_or_domain);
            return false;
        }
    }

    public static void main(String[] args) {
