端口扫描器--利用python的nmap模块

安装nmap模块挺麻烦的，搞了半天

不仅要安装pip install nmap

还要sudo apt install nmap

给出代码，没有设多线程，有点慢，注意端口的类型转换，搞了很久

#!/usr/bin/env python
# -*- coding:UTF-8 -*-
import optparse
import nmap

#usage:python scan.py -H 119.75.217.26 -p 3306 80 22

def nampScan(tgtHost,tgPort):
    nmScan = nmap.PortScanner()
    try:
        result = nmScan.scan(tgtHost,str(tgPort))
        state =  result[‘scan‘][tgtHost][‘tcp‘][int(tgPort)][‘state‘]
        service = result[‘scan‘][tgtHost][‘tcp‘][int(tgPort)][‘product‘]
        version = result[‘scan‘][tgtHost][‘tcp‘][int(tgPort)][‘version‘]
        print "[*]" + tgtHost + " tcp/" + str(tgPort) + " " + state + " " + service + " " + version
    except:
        pass

def main():
    parse = optparse.OptionParser(‘usage %prog -H <targethost> -p <targetport>‘)
    parse.add_option(‘-H‘,dest = ‘tgtHost‘,type = ‘string‘,help = ‘specify target host‘)
    parse.add_option(‘-p‘,dest = ‘tgtPort‘,type = ‘int‘,help = ‘specify target port‘)
    (option,args) = parse.parse_args()
    tgtHost = option.tgtHost
    tgtPort = str(option.tgtPort)
    args.append(tgtPort)
    if(tgtHost == None)|(tgtPort == None):
        print "[-]usage : python scan.py -H 192.168.2.3 -p 3306 80 22"
        exit(0)
    for tgport in args:
        nampScan(tgtHost,tgport)

if __name__ == ‘__main__‘:
    main()
