How can i pass the ip address to a nmap scanner?

Question

I have a code which basically returns 3 things

ip, instance_tag_name, availability_zone

as follows :

def call_me ():

  ACCESS_KEY= "XXXXXXXXXXXX"

  SECRET_KEY= "XXXXXXXXXXXXXXXXXXX"

  regions = ['us-west-2','eu-central-1','ap-southeast-1']

  combined_shit = []

  for region in regions:

    instance_information = {}

    ip_dict = {}

    client = boto3.client('ec2',aws_access_key_id=ACCESS_KEY,aws_secret_access_key=SECRET_KEY,region_name=region,)

    addresses_dict = client.describe_addresses().get('Addresses')



    for address in addresses_dict:



        if address.get('InstanceId'):

            instance_information[address['InstanceId']] = [address.get('PublicIp')]

         #   print  instance_information



    dex_dict = client.describe_tags().get('Tags')

    for dex in dex_dict:

        if instance_information.get(dex['ResourceId']):

            instance_information[dex['ResourceId']].append(dex.get('Value'))

    for instance in instance_information:



        if len(instance_information[instance]) == 2:

            ip_dict[instance_information[instance][0]] = instance_information[instance][1]

        else:

            ip_dict[instance_information[instance][0]] = ''

#    print (json.dumps(instance_information,indent=4))

    #print type(instance_information)

    ip_list = [i[0]  for i in instance_information.values()]

    tag_list = [i[1] for i in instance_information.values()]

    region_list = []

    for i in instance_information.values():

        try:

            region_list.append(i[3])

        except:

            region_list.append("")

    #print (ip_list)

    combined_result = list(zip(ip_list, tag_list, region_list))

    combined_shit.append(combined_result)

  return str(combined_shit)

The

combined_shit

function returns something like this :

[[('52.1.113.171', ' Exclusive LB', ''), ('52.26.2.83', 'pdx-cloud-1-LB', 'us-west-2'), ('51.25.14.146', 'SDlusive LB', ''),........]]

I have a Nmap parser written which basically takes in the IP addresses and scans it, now how can i pass the above list of addresses to function such that it reads on the IP's address ?

The nmap caller looks like

 net_range = call_me()  

 r = s.run(net_range)

The run() method looks like :

 def run(self, targets="" ,options="-Pn  -p 80,443,22,8980,5601,3306,9200,8080,3128"):

        #start a new nmap scan on localhost with some specific options



        syslog.syslog("Scan started")

        parsed = None

        nmproc = NmapProcess(targets,options)

        rc = nmproc.run()

        nmproc.run_background()

        while nmproc.is_running()

        ..

So the question is how can i pass just the IP's to this caller & there is yet another reason to keep the rest information. But first if this can be solved

Answer 1

I think your NMAP run requires a comma separated list of IPs. Here's how to do it.

r = s.run(net_range)

net_range is a list of tuples which have IPs at index 0. We get the list of IPs and join it to create a comma separated string of IPs.

Change your run as follows.

def run(self, data ,options="-Pn  -p 80,443,22,8980,5601,3306,9200,8080,3128"):
    #start a new nmap scan on localhost with some specific options
    targets=','.join(list(itertools.chain(*[[j[0] for j in i] for i in data])))
    tags = list(itertools.chain(*[[j[1] for j in i] for i in data]))
    regions = list(itertools.chain(*[[j[2] for j in i] for i in data]))
