('Nmap not found', )

Question

Where is the problem?

import nmap

I installed nmap and python, and when I use import nmap there is no any problem. But when us

Note about nmap

I used nmap to search the mask 192.168.1.0/24, but it didnt seam to find ALL ip´s. Eg: my laptop on 192.168.1.119 wasnt found, so I ended up using a combination of:

def ping(self, ip):
    # Use the system ping command with count of 1 and wait time of 1.
    ret = subprocess.call(['ping', '-c', '1', '-W', '1', ip],
                          stdout=open('/dev/null', 'w'),
                          stderr=open('/dev/null', 'w'))

    return ret == 0 # Return True if our ping command succeeds

inside a multithreaded Pinger

Pinger I got from: http://blog.boa.nu/2012/10/python-threading-example-creating-pingerpy.html

I created my own IpInfo class to store information and search for open ports on each IP, and here I use nmap: (Code is "work in progress", but you will get the idea. Ideas to tune performance would be nice)

class IpInfo(object):
ip = None
hostname = None
ports = []
lastSeenAt = strftime("%Y-%m-%d %H:%M:%S", gmtime())


def findHostName(self):
    if(ip):
        self.hostname = str(socket.gethostbyaddr(ip)[0])
    else:
        raise NameError('IP missing')

def findOpenPorts(self):
    print('findOpenPorts')
    nm = nmap.PortScanner()
    nm.scan(host)
    nm.command_line()
    nm.scaninfo()

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

        lport = nm[self.ip][proto].keys()   #<------ This 'proto' was changed from the [proto] to the ['tcp'].
        lport.sort()

        for port in lport:
            if(nm[self.ip][proto][port]['state'] == 'open'):
                self.ports.append(port)
