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 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
######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).split('-')
if(len(tgtPorts_split) < 2):
tgtPorts.extend(tgtPorts_split)
#print(tgtPorts)
else:
for n in range(int(tgtPorts_split),int(tgtPorts_split)+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 == None):
print (parser.usage)
exit(0)
for tgtPort in tgtPorts:
nmapScan(tgtHost, tgtPort)
if __name__ == '__main__':
main()
