Scan a Single Host or an IP Address. Scan a Single IP Address: $ nmap 192.168.1.1.
With the ubiquity of mobile devices and cheap commoditynetworking equipment, companies are increasingly finding thatemployees are extending their networks in undesirable ways. Among themost dangerous devices are 802.11 wireless access points (WAPs). Users mayinstall a $20 WAP in their cubicle so they can work from the breakroom, without realizing (or caring) that they just opened theprotected corporate network to potential attackers in the parking lotor nearby buildings.

Some WAP installations are even worse than those installed by naive users.Breaching a building's security is much riskier for an attacker thanaccessing corporate data from far away through a network. It carries the risk ofbeing arrested on the spot. So attackers have been known to installcompact WAPs so they can then intrude on the network at will from therelative safety of a car down the street. A WAP taped under a desk orotherwise hidden is unlikely to be noticed for a while.
While the focus of this solution is finding WAPs, the samestrategy can be used to find just about anything. You might need tolocate all Cisco routers to apply a new patch or Solaris boxes todetermine whether you have enough systems to warrant paying forsupport. Download video player for mac.
One way to find unauthorized wireless devices is to sweep thearea with a wireless sniffer such as Kismetor NetStumbler.Anotherapproach is to scan the wired side with Nmap. Not surprisingly, thissolution focuses exclusively on the latter approach. Each techniquecan miss certain WAPs, so the best approach is to do both and merge the results.

This is a python class to use nmap and access scan results from python3
Project description
python-nmap
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 nmap.py module
nm = nmap.PortScanner() # instantiate nmap.PortScanner object
nm.scan('127.0.0.1', '22-443') # scan host 127.0.0.1, ports from 22 to 443
nm.command_line() # get command line used for the scan : nmap -oX - -p 22-443 127.0.0.1
nm.scaninfo() # get nmap scan informations {'tcp': {'services': '22-443', 'method': 'connect'}}
nm.all_hosts() # get all hosts that were scanned
nm['127.0.0.1'].hostname() # get one hostname for host 127.0.0.1, usualy the user record
nm['127.0.0.1'].hostnames() # get list of hostnames for host 127.0.0.1 as a list of dict
# [{'name':'hostname1', 'type':'PTR'}, {'name':'hostname2', 'type':'user'}]
nm['127.0.0.1'].hostname() # get hostname for host 127.0.0.1
nm['127.0.0.1'].state() # get state of host 127.0.0.1 (up|down|unknown|skipped)
nm['127.0.0.1'].all_protocols() # get all scanned protocols ['tcp', 'udp'] in (ip|tcp|udp|sctp)
nm['127.0.0.1']['tcp'].keys() # get all ports for tcp protocol
nm['127.0.0.1'].all_tcp() # get all ports for tcp protocol (sorted version)
nm['127.0.0.1'].all_udp() # get all ports for udp protocol (sorted version)
nm['127.0.0.1'].all_ip() # get all ports for ip protocol (sorted version)
nm['127.0.0.1'].all_sctp() # get all ports for sctp protocol (sorted version)
nm['127.0.0.1'].has_tcp(22) # is there any information for port 22/tcp on host 127.0.0.1
nm['127.0.0.1']['tcp'][22] # get infos about port 22 in tcp on host 127.0.0.1
nm['127.0.0.1'].tcp(22) # get infos about port 22 in tcp on host 127.0.0.1
nm['127.0.0.1']['tcp'][22]['state'] # get state of port 22/tcp on host 127.0.0.1 (open
# a more usefull example :
for host in nm.all_hosts():
print('----------------------------------------------------')
print('Host : %s (%s)' % (host, nm[host].hostname()))
print('State : %s' % nm[host].state())
for proto in nm[host].all_protocols():
print('----------')
print('Protocol : %s' % proto)
lport = nm[host][proto].keys()
lport.sort()
for port in lport:
print('port : %ststate : %s' % (port, nm[host][proto][port]['state']))
print('----------------------------------------------------')
# print result as CSV
print(nm.csv())
print('----------------------------------------------------')
# If you want to do a pingsweep on network 192.168.1.0/24:
nm.scan(hosts='192.168.1.0/24', 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='192.168.1.0/30', 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
