Mastering Python for Networking and Security

Synchronous scanning

In this example, we implemented a class that allows us to scan an IP address and a list of ports that are passed to the script as a parameter.

In the main program, we add the necessary configuration for the treatment of the input parameters. We perform a loop that processes each port sent by parameter, and call the nmapScan (ip, port) method of the NmapScanner class.

You can find the following code in the filename: NmapScanner.py:

import optparse, nmapclass NmapScanner:    def __init__(self):        self.nmsc = nmap.PortScanner()    def nmapScan(self, host, port):        self.nmsc.scan(host, port)        self.state = self.nmsc[host]['tcp'][int(port)]['state']        print " [+] "+ host + " tcp/" + port + " " + self.statedef main(): parser = optparse.OptionParser("usage%prog ...
