这篇文章主要为大家详细介绍了Python端口扫描简单程序的实现方法,具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了Python 端口扫描的实现代码，供大家参考，具体内容如下

获取本机的IP和端口号:

									import socket 

									def get_my_ip(): 

									  try: 

									    csock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) 

									    csock.connect(('8.8.8.8', 80)) 

									    (addr, port) = csock.getsockname() 

									    csock.close() 

									    return addr,port 

									  except socket.error: 

									    return "127.0.0.1"

									def int_to_ip(int_ip): 

									  return socket.inet_ntoa(struct.pack('I', socket.htonl(int_ip))) 

									def ip_to_int(ip): 

									  return socket.ntohl(struct.unpack("I", socket.inet_aton(str(ip)))[0]) 

									(ip,port)=get_my_ip() 

									print "ip=%s port=%d" %(ip,port)

PortScan.py

									# -*- coding: utf-8 -*- 

									import optparse 

									from socket import *

									from threading import *

									screenLock = Semaphore(value=1) 

									def connScan(tgtHost, tgtPort): 

									  try: 

									    connSkt = socket(AF_INET, SOCK_STREAM) 

									    connSkt.connect((tgtHost, tgtPort)) 

									    connSkt.send('ViolentPython\r\n') 

									    results = connSkt.recv(100) 

									    screenLock.acquire() 

									    print '[+] %d/tcp open' % tgtPort 

									    print '[+] ' + str(results) 

									  except: 

									    screenLock.acquire() 

									    print '[-] %d/tcp closed' % tgtPort 

									  finally: 

									  screenLock.release() 

									  connSkt.close()  

									def portScan(tgtHost, tgtPorts): 

									  try: 

									    tgtIP = gethostbyname(tgtHost) 

									  except: 

									    print "[-] Cannot resolve '%s': Unknown host" %tgtHost 

									    return

									  try: 

									    tgtName = gethostbyaddr(tgtIP) 

									    print '\n[+] Scan Results for: ' + tgtName[0] 

									  except: 

									    print '\n[+] Scan Results for: ' + tgtIP 

									  setdefaulttimeout(1) 

									  for tgtPort in tgtPorts: 

									    t = Thread(target=connScan,args=(tgtHost,int(tgtPort))) 

									    t.start() 

									def main(): 

									  parser = optparse.OptionParser('usage %prog '+\ 

									   '-H <target host> -p <target port>') 

									  parser.add_option('-H', dest='tgtHost', type='string',\ 

									   help='specify target host') 

									  parser.add_option('-p', dest='tgtPort', type='string',\ 

									   help='specify target port[s] separated by comma') 

									  (options, args) = parser.parse_args() 

									  tgtHost = options.tgtHost 

									  tgtPorts = str(options.tgtPort).split(',') 

									  if (tgtHost == None) | (tgtPorts[0] == None): 

									  print parser.usage 

									    exit(0) 

									  portScan(tgtHost, tgtPorts) 

									if __name__ == '__main__': 

									  main()
