python-nmap 0.3.1

This is a python class to use nmap and access scan results from python3

Latest Version: 0.4.3


python-nmap is a python library which helps in using nmap port scanner.
It allows to easilly manipulate nmap scan results and will be a perfect
tool for systems administrators who want to automatize scanning task
and reports. It also supports nmap script outputs.

Typical usage looks like::

#!/usr/bin/env python
import nmap # import module
nm = nmap.PortScanner() # instantiate nmap.PortScanner object
nm.scan('', '22-443') # scan host, ports from 22 to 443
nm.command_line() # get command line used for the scan : nmap -oX - -p 22-443
nm.scaninfo() # get nmap scan informations {'tcp': {'services': '22-443', 'method': 'connect'}}
nm.all_hosts() # get all hosts that were scanned
nm[''].hostname() # get hostname for host
nm[''].state() # get state of host (up|down|unknown|skipped)
nm[''].all_protocols() # get all scanned protocols ['tcp', 'udp'] in (ip|tcp|udp|sctp)
nm['']['tcp'].keys() # get all ports for tcp protocol
nm[''].all_tcp() # get all ports for tcp protocol (sorted version)
nm[''].all_udp() # get all ports for udp protocol (sorted version)
nm[''].all_ip() # get all ports for ip protocol (sorted version)
nm[''].all_sctp() # get all ports for sctp protocol (sorted version)
nm[''].has_tcp(22) # is there any information for port 22/tcp on host
nm['']['tcp'][22] # get infos about port 22 in tcp on host
nm[''].tcp(22) # get infos about port 22 in tcp on host
nm['']['tcp'][22]['state'] # get state of port 22/tcp on host (open

# a more usefull example :
for host in nm.all_hosts():
print('Host : %s (%s)' % (host, nm[host].hostname()))
print('State : %s' % nm[host].state())

for proto in nm[host].all_protocols():
print('Protocol : %s' % proto)

lport = nm[host][proto].keys()
for port in lport:
print('port : %s\tstate : %s' % (port, nm[host][proto][port]['state']))

# print result as CSV

# If you want to do a pingsweep on network
nm.scan(hosts='', arguments='-n -sP -PE -PA21,23,80,3389')
hosts_list = [(x, nm[x]['status']['state']) for x in nm.all_hosts()]
for host, status in hosts_list:
print('{0}:{1}'.format(host, status))

print '----------------------------------------------------'
# Asynchronous usage of PortScannerAsync
nma = nmap.PortScannerAsync()
def callback_result(host, scan_result):
print '------------------'
print host, scan_result
nma.scan(hosts='', arguments='-sP', callback=callback_result)
while nma.still_scanning():
print("Waiting ...")
nma.wait(2) # you can do whatever you want but I choose to wait after the end of the scan


2013/07/27 (v0.3.1)
- Bug correction on callback's assert in PortScannerAsync.scan
proposed by Robert Bost

2013/06/23 (v0.3.0)
- added support for NMAP SCRIPT ENGINE
>>> r=nm.scan(hosts='', ports='139', arguments="-sC ")
>>> print(nm._scan_result['scan']['']['hostscript'])

2013/02/24 (v0.2.7)
- added an address block in host scan result which contains ipv4, mac and other addresses :
nm = nmap.PortScanner()
r = nm.scan(arguments='-sS -p T:22', hosts='')
print r['scan']['']['addresses']
{u'mac': u'02:50:43:F4:02:B1', u'ipv4': u''}
- Adding a CSV scan output as a string.
- Changes to make it python3 compliant

2012/12/13 (v0.2.6)
- patch from lundberg.johan
- bug correction : when nmap doesn't work displays stderr instead of stdout

2012/11/23 (v0.2.5)
- corrected : Issue 2: "map.nmap.PortScannerError: 'nmap program was not found in path'" on CentOS
- corrected : Issue 3: nmap.scan() short-circuits prematurely

2011/11/09 (v0.2.4)
- implemented a request from Santhosh Edukulla <> :
parse OS scanning output
- Error with multiple host specifications :
bug and patch from

- bug in : if no tcp port was open between 22-443

2010/12/17 (v0.2.3)
- adding __get_last_online_version to check if current version is the last published

2010/12/17 (v0.2.2)
- bug in handling nmap_error output (returned value was bin, string was expected)
- removed test strings form file.

2010/12/15 (v0.2.1)
- corrected bug in about scope problem
- try to find nmap executable in known directories
- raise AssertionError when trying to call command_line, scaninfo, scanstats, has_host before scanning

2010/12/14 (v0.2.0)
- Make python-nmap works with Python 3.x
- Contribution from Brian Bustin <brian at="""">

2010/06/07 (v0.1.4)
Patches from Steve 'Ashcrow' Milner <steve at="""">
- remove shebang from as it is not a runnable script
- allow use with ALPHA and BETA nmap releases
- .has_key() is deprecated, replaced instances with in
- move to using the print function for python2 and 3 usage

- adding PortScanner.listscan
- PortScanner.scan now returns scan_result
- adding class PortScannerAsync (idea from Steve 'Ashcrow' Milner <steve at="""">)

- Import on google code
svn checkout python-nmap --username XXXXX
- added PortScanner.scanstats method
- updated and documentation for pingsweep
- updated Makefile for generating documentation

- Modified packaging. v0.1.1 [norman]

- Initial release. v0.1.0 [norman]
