Python端口扫描 Python端口扫描简单程序
Linux_Google 人气:1想了解Python端口扫描简单程序的相关内容吗,Linux_Google在本文为您仔细讲解Python端口扫描的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:python,端口扫描,下面大家一起来学习吧。
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
#!/usr/bin/python # -*- 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()
