Trying to use python-nmap but receiving however python2 or 3 can't find PortScanner.

[PythonNmap]

I'm editing it in the same folder and user that I'm running it from.

Any way to get more debug info to trace where it's getting it's packages from?

[buran]

add following to your script, e.g. inside if __name__ == '__main__': block
quick and dirty:

import os
print(os.path.abspath(nmap.__file__)

or using inspect module from Standard Library:

import inspect
print(inspect.getfile(nmap))

[PythonNmap]

Hmm, this is handy. Used this code:

print(nmap.__file__)

and it printed

/usr/local/lib/python3.6/site-packages/nmap/__init__.py

I have python 2.7.X installed as well. The nmap module for that guy is:

/usr/lib/python2.7/site-packages/nmap
[root@server01 nmap]# ls -altri
total 140

[root@server01 nmap]#

So switched to python 2.7 temporarily just to see if finds the above.  Now it gives a different error, so looks like it progressed to the next problem:

[python]
$  ./ip-get.py vlan2.xml
/usr/lib/python2.7/site-packages/nmap/__init__.pyc

I'll try the second bit of code now. Looks like we were thinking the same.

[buran]

Hm. that is strange
you have python-nmap installed for both python2 and python3

so, you shoould have also /usr/local/lib/python3.6/site-packages/nmap/nmap.py file
the __init__.py you show imports everything from it, incl PortScanner.

Can you check that that file is there and also __init__.py file has from .nmap import * line?

you can have a look at the package structure in the source https://xael.org/pages/python-nmap-0.6.1.tar.gz or in the repo https://bitbucket.org/xael/python-nmap/src/default/

As to the error you get in python2 - python-nmap package is wrapper that makes easy to automate running nmap port scanner - https://nmap.org/

i.e. as far as I understand it - you need to install nmap port scanner utility separately

Yep, the above file exists.

$ cat __init__.py

Ya, looks good:

[user@server01 nmap]$ cat __init__.py

Ya, I see nmap is missing from my system. That's an easy fix I'll do now.

I thought I did install it separately. When you say 'separately', what do you consider 'separately'?

Tried to install python3-nmap, since python3 is the future:

pip search nmap
python3-nmap (1.3.1)     - Python3-nmap converts Nmap commands into python3 methods making it very easy to use nmap in any of your python pentesting projects

pip install python3-nmap
ERROR: Could not find a version that satisfies the requirement python3-nmap (from versions: none)
ERROR: No matching distribution found for python3-nmap

Though it comes up in search, it fails to install. When I switch the interpreter to python3, since I would like to use the latest supported version, I get the original error:

from .nmap import nmap

that doesn't look right
if you look at the source code, it's

from .nmap import *

and it's even more strange because you should get

Error:
ImportError: cannot import name 'nmap' from 'nmap.nmap'

python-nmap works with python3 - I installed it on my system (linux mint) in virtual environment and I got the same error you got in python2

Error:
nmap.nmap.PortScannerError: 'nmap program was not found in path

I don't have nmap installed on my systems, so it's not available

Tried to install python3-nmap, since python3 is the future:

python3-nmap is different package, I didn't look into it

install separately - that it nmap tool should be available on your system, python-nmap will not install it, you should install it yourself if not available

python-nmap will install correctly depending on the python version in which it is installed. As I said I installed it on my python3.7 without any issues

[PythonNmap]

Tried nmap3.

#!/bin/python3

import sys
import getopt
import nmap3

import inspect
print(inspect.getfile(nmap3))

print(nmap3.__file__)

import xml.dom.minidom, xml.etree.ElementTree as et

def nmapScan(vlan, netmask):
    # NMAP VLAN to determine IP availability.
    print ("NMAP Scanner")
    nm = nmap3.PortScanner ()


def main():
    xmltree = et.parse(sys.argv[1])

    # XML Tree Item = xti
    for xti in xmltree.iter('AR'):
        network_address = xti.find('NETWORK_ADDRESS').text
        network_mask = xti.find('NETWORK_MASK').text

        print ("[*] Network Address: ", network_address)
        print ("[*] Network Mask: ", network_mask)

    nmapScan(network_address, network_mask)

if __name__ == "__main__":
    main();

But that looks like it's a different animal altogether. It doesn't have the PortScanner function apparently, so that's a valid error message.

Don't see much documentation for nmap3. Basing it on only a few google queries however.

[buran]

did you install python-nmap on python3 yourself or it was already installed by someone else? is it possible that someone changed something? uninstall it and install it again
as I said - from .nmap import nmap should not be in the __init__.py

obviously the one in python2 is OK and should work once nmap tool is installed

---

This is interesting
https://bitbucket.org/xael/python-nmap/i...ortscanner

most of them had the problem because of having their own nmap.py that was creating problems. Original poster however looks like legit problem.

[PythonNmap]

I uninstalled all nmap python3 modules I could find and installed the specific python-nmap from python2 onto the python3 libraries, and it appears to have worked like a charm:

# python3 -m pip install python-nmap
WARNING: Running pip install with root privileges is generally not a good idea. Try `__main__.py install --user` instead.

Installing collected packages: python-nmap
  Running setup.py install for python-nmap ... done
Successfully installed python-nmap-0.6.1

Output now is:

$

Full code:

#!/bin/python3

import sys
import getopt
import nmap

import inspect
print(inspect.getfile(nmap))

print(nmap.__file__)

import xml.dom.minidom, xml.etree.ElementTree as et

def nmapScan(vlan, netmask):
    # NMAP VLAN to determine IP availability.
    print ("NMAP Scanner")
    nm = nmap.PortScanner ()


def main():
    xmltree = et.parse(sys.argv[1])

    # XML Tree Item = xti
    for xti in xmltree.iter('AR'):
        network_address = xti.find('NETWORK_ADDRESS').text
        network_mask = xti.find('NETWORK_MASK').text

        print ("[*] Network Address: ", network_address)
        print ("[*] Network Mask: ", network_mask)

    nmapScan(network_address, network_mask)

if __name__ == "__main__":
    main();

So I suppose I can consider this issue resolved now.

Thankx very much!

[buran]

just to make it clear - python-nmap supports BOTH 2 and 3, don't make the assumption it's just python2 because it doesn't say python3, like the other package.
