python3实现指定IP多线程端口扫描

1、socket实现端口扫描

#!/usr/bin/python3
#-*- coding:utf-8 -*-

#编写环境  windows 7 x64 + Python3.7.0
#socket实现端口扫描

import socket
import time

def scan(ip, port):
    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    try:
        server.connect((ip,port))
        print('{0} port {1} is open'.format(ip, port))
    except Exception as e:
        print('{0} port {1} is off'.format(ip,port))
    finally:
        server.close()

def scanport():
    
    ip = '10.10.10.3'
    print('{0}'.format(ip))
    portlist = [22,443,80,21,23,3306,1433,1521,3389,5432,6379,7001]
    #portlist = [80,443]
    starttime = time.time()
    
    for port in portlist:
        scan(ip, port)
        
    endtime = time.time()
    print('一共运行了{0}秒'.format((endtime-starttime)))

if __name__ == '__main__':
    scanport()

2、telnetlib实现端口扫描

#!/usr/bin/python3
#-*- coding:utf-8 -*-

#编写环境  windows 7 x64 + Python3.7.0
#telnetlib实现端口扫描

import telnetlib
import time

def scan(ip, port):
    server = telnetlib.Telnet()      # 创建一个Telnet对象
    try:
        server.open(ip,port)         # 利用Telnet对象的open方法来创建TCP连接测试端口是否开放
        print('{0} port {1} is open'.format(ip, port))
    except Exception as e:
        print('{0} port {1} is off'.format(ip,port))
    finally:
        server.close()

def scanport():
    
    ip = '10.10.10.3'
    print('{0}'.format(ip))
    portlist = [22,443,80,21,23,3306,1433,1521,3389,5432,6379,7001]
    #portlist = [80,443]
    starttime = time.time()
    
    for port in portlist:
        scan(ip, port)
        
    endtime = time.time()
    print('一共运行了{0}秒'.format((endtime-starttime)))

if __name__ == '__main__':
    scanport()

3、多线程实现端口扫描

#!/usr/bin/python3
#-*- coding:utf-8 -*-

#编写环境  windows 7 x64 + Python3.7.0
#telnetlib实现端口扫描

import telnetlib
import threading
import time

def scan(ip, port):
    server = telnetlib.Telnet()      # 创建一个Telnet对象
    try:
        server.open(ip,port)         # 利用Telnet对象的open方法来创建TCP连接测试端口是否开放
        print('{0} port {1} is open'.format(ip, port))
    except Exception as e:
        print('{0} port {1} is off'.format(ip,port))
    finally:
        server.close()

def scanport():
    
    ip = '10.10.10.3'
    print('{0}'.format(ip))
    portlist = [22,443,80,21,23,3306,1433,1521,3389,5432,6379,7001]
    #portlist = [80,443]
    starttime = time.time()
    
    threads = []
    for port in portlist:
        t = threading.Thread(target=scan,args=(ip,port))
        t.start()
        threads.append(t)
    
    for t in threads:
        t.join()
    endtime = time.time()
    print('一共运行了{0}秒'.format((endtime-starttime)))

if __name__ == '__main__':
    scanport()
