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-8 import socket, sys, thread, time openportnum = 0 socket.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)
