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 likescan_network.py
[*] #!/usr/bin/env python
[*] import nmap
[*] import optparse
[*]
[*] def nmapScan(tgtHost,tgtPort):
[*] nmScan = nmap.PortScanner()
[*] nmScan.scan(tgtHost,tgtPort)
[*] state=nmScan['tcp']['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 separated by comma')
[*]
[*] (options, args) = parser.parse_args()
[*]
[*] tgtHost = options.tgtHost
[*] tgtPorts = str(options.tgtPort).split(',')
[*]
[*] if (tgtHost == None) | (tgtPorts == None):
[*] print (parser.usage)
[*] exit(0)
[*] for tgtPort in tgtPorts:
[*] nmapScan(tgtHost, tgtPort)
[*]
[*]
[*] if __name__ == '__main__':
[*] main
Forthly：chmod +xscan_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 pythonimport nmapimport optparsedef nmapScan(tgtHost,tgtPort): nmScan = nmap.PortScanner() nmScan.scan(tgtHost,tgtPort) state=nmScan['tcp']['state'] print ("
