把每个睡醒后的早晨当成一件礼物，把每个开心后的微笑当成一个习惯。朋友，短信祝早上好，愿你微笑今天，快乐永远！有勇气并不表示恐惧不存在，而是敢面对恐惧克服恐惧。
本文实例为大家分享了python 3.6.7端口扫描器的具体代码，供大家参考，具体内容如下
环境：python 3.6.7
# -*- coding: utf-8 -*-
import socket
import threading
import argparse
lock = threading.Lock()
openNum = 0
threads = []
def portscan(ip, port):
global openNum
try:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((ip, port))
lock.acquire()
openNum = openNum + 1
print('[+] %d open' %port)
lock.release()
s.close()
except:
pass
def main():
parse = argparse.ArgumentParser()
parse.add_argument('-H', dest = 'ip', type = str)
args = parse.parse_args()
ip = args.ip
socket.setdefaulttimeout(3)
for port in range(1, 1024):
t = threading.Thread(target = portscan, args = (ip, port))
threads.append(t)
t.start()
for t in threads:
t.join()
print('[*] The host:%s scan is complete!' %(ip))
print('[*] A total of %d open port ' %(openNum))
if __name__ == '__main__':
main()
