简单端口扫描工具

这是一个简单的端口扫描工具，可以实现一般的端口扫描功能。

由Python编写，所以效率略低@[email protected]

源代码：

‘’’# ！bin/usr/python/bin’’’
‘’’# _coding_:utf-8’’’

import socket
import threading
import time

socket.setdefaulttimeout(3)
mlock = threading.RLock()

def socket_port(ip, port):
try:
if port >= 65535:
print(u”端口扫描结束 0-65535”)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = s.connect_ex((ip, port))
if (result == 0):
mlock.acquire() #加锁
print(ip, u”:”, port, u”端口开放”)
mlock.release() #释放锁
s.close()
except:
print(u”异常2”)

def ip_port(data):
try:
t = time.time()
for i in range(80, 65535):
threading.Thread(target=socket_port(data, int(i))).start()
print(u”扫描端口完成用时 time:%f” % (time.time() - t))
except:
print(u”异常1”)

if name == ‘main‘:
ip_port(“127.0.0.1”)
