I wrote the below code

    pid = os.fork()
    port = random.randint(30000, 40000)
    if (pid > 0):
        result = {}
        def addresult(res):
            if (res[0] not in result):
                result[res[0]] = [res[1]]
            elif (res[1] not in result[res[0]]):
                result[res[0]].append(res[1])
        iface = conf.route.route('127.0.0.1')[0]
        count = 14
        pl = sniff(iface=iface, filter=('tcp    and    port    ' + str(port)), count=count, timeout=3)
        map(addresult, map(packet2p0f, pl))
        os.waitpid(pid, 0)
    elif (pid < 0):
        log_runtime.error('fork    error')
    else:
        time.sleep(1)
        s1 = socket.socket(socket.AF_INET, type=socket.SOCK_STREAM)
        try:
            s1.connect(('127.0.0.1', port))
        except socket.error:
            pass
        s1.bind(('127.0.0.1', port))
        s1.connect(('127.0.0.1', port))
        s1.close()
        os._exit(0)
    return result
