本文实例讲述了python实现的多线程端口扫描功能。分享给大家供大家参考，具体如下：

下面的程序给出了对给定的ip主机进行多线程扫描的Python代码

#!/usr/bin/env python#encoding: utf-8import socket, sys, thread, timeopenPortNum = 0socket.setdefaulttimeout(3)def usage(): print '''''Usage: Scan the port of one IP: python port_scan_multithread.py -o <ip> Scan the port of one IP: python port_scan_multithread.py -m <ip1, ip2, ip3, ip4 ...> ''' print 'Exit' sys.exit(1)def socket_port(ip, PORT): global openPortNum if PORT > 65535: print 'Port scanning beyond the port range, interrupt to scan' sys.exit(1) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) result = s.connect_ex((ip, PORT)) if(result == 0): print ip, PORT,'is open' openPortNum += 1 s.close()def start_scan(IP): for port in range(0, 65535+1): thread.start_new_thread(socket_port, (IP, int(port))) time.sleep(0.006)if __name__ == '__main__': t = 0 if len(sys.argv)<2 or sys.argv[1] == '-h': usage() elif sys.argv[1] == '-o': ONE_IP = raw_input('Please input ip of scanning: ') t = time.time() start_scan(ONE_IP) elif sys.argv[1] == '-m': MANY_IP = raw_input('Please input many ip of scanning: ') IP_SEG = MANY_IP.split(',') t = time.time() for i in IP_SEG: start_scan(i) print print 'total open port is %s, scan used time is: %f ' % (openPortNum, time.time()-t)
