Examples of multithreaded port scanning capabilities implemented by Python

The example in this paper describes the multi-threaded port scanning function implemented by Python. Share to everyone for your reference, as follows:

The following program gives the Python code for multithreaded scanning of a given IP host

#!/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, P ORT): Global openportnum If port > 65535:print ' port scanning beyond the port range, interrupt to scan ' Sys.ex It (1) s = socket.socket (socket.af_inet, socket.
