Two methods for using nmap port scanning in python

This article introduces two methods for using nmap port scanning in python: The first version only supports ports separated by commas and does not support Port ranges.

Firstly: sudo apt-get install nmap

Secondly: pip install python-nmap

Thirdly: copy the code bellow to a file like scan_network.py

#!/usr/bin/env pythonimport nmapimport optparsedef nmapScan(tgtHost,tgtPort):    nmScan = nmap.PortScanner()    nmScan.scan(tgtHost,tgtPort)    state=nmScan[tgtHost]['tcp'][int(tgtPort)]['state']    print ("[*] " + tgtHost + " tcp/"+tgtPort +" "+state)def main():    parser = optparse.OptionParser('usage %prog '+\                                   '-H 
 
   -p 
  
   ')    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)    for tgtPort in tgtPorts:        nmapScan(tgtHost, tgtPort)if name == 'main':    main
  
 

Forthly: chmod + x scan_network.py

Export thly:./scan_network.py-H 192.168.1.1-p

Version 2: supports comma-separated and-separated port ranges

#!/usr/bin/env pythonimport nmapimport optparsedef nmapScan(tgtHost,tgtPort):    nmScan = nmap.PortScanner()    nmScan.scan(tgtHost,tgtPort)    state=nmScan[tgtHost]['tcp'][int(tgtPort)]['state']    print ("[*] " + tgtHost + " tcp/"+tgtPort +" "+state)def main():    parser = optparse.OptionParser('usage %prog '+\                                   '-H 
 
   -p 
  
   ')    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######this code bellow is to support scan port range like 66-88    tgtPorts = []    tgtPorts_cache = str(options.tgtPort).split(',')    i = int(len(tgtPorts_cache))    for m in range( 0,i ):        tgtPorts_split = str(tgtPorts_cache[m]).split('-')        if(len(tgtPorts_split) < 2):            tgtPorts.extend(tgtPorts_split)            #print(tgtPorts)        else:            for n in range(int(tgtPorts_split[0]),int(tgtPorts_split[1])+1):                tgtPorts.append(str(n))                #print(tgtPorts)######above the tgtPorts are the ports list you want to scann    #tgtPorts = str(options.tgtPort).split(',')        if (tgtHost == None) | (tgtPorts[0] == None):        print (parser.usage)        exit(0)    for tgtPort in tgtPorts:        nmapScan(tgtHost, tgtPort)if name == 'main':    main()
