python使用nmap端口扫描

第一版：只支持以逗号分隔的端口，不支持端口范围  

Firstly：      sudo apt-get install nmap

Secondly：pip install python-nmap

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

1. #!/usr/bin/env python
2. import nmap
3. import optparse
5. def nmapScan(tgtHost,tgtPort):
6.    nmScan = nmap.PortScanner()
7.    nmScan.scan(tgtHost,tgtPort)
8.    state=nmScan[tgtHost]['tcp'][int(tgtPort)]['state']
9. print ("[*] " + tgtHost + " tcp/"+tgtPort +" "+state)
11. def main():
12.    parser = optparse.OptionParser('usage %prog '+\
13. '-H <target host> -p <target port>')
14.    parser.add_option('-H', dest='tgtHost', type='string',\
15.                      help='specify target host')
16.    parser.add_option('-p', dest='tgtPort', type='string',\
17.                      help='specify target port[s] separated by comma')
19. (options, args) = parser.parse_args()
21.    tgtHost = options.tgtHost
22.    tgtPorts = str(options.tgtPort).split(',')
24. if (tgtHost == None) | (tgtPorts[0] == None):
25. print (parser.usage)
26.        exit(0)
27. for tgtPort in tgtPorts:
28.        nmapScan(tgtHost, tgtPort)
31. if __name__ == '__main__':
32.    main

Forthly：chmod +x  scan_network.py   

fifthly:      ./scan_network.py -H 192.168.1.1 -p 22,23

第二版：支持以逗号分割及以-分割的端口范围

#!/usr/bin/env python import nmap import optparse def 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 <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 ######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()
