Python Implements port status scanning

A Python namp module is required to implement port status scanning.

First to address: Https://pypi.python.org/pypi/python-nmap Download the Namp package.

I downloaded the version 0.6.1, the OS is CentOS 7.

Execute the following command to install the Namp module:

CD python-nmap-0.6.1

Python setup Install

The Python implementation code is as follows:

#!/usr/bin/env python

#-*-Coding:utf-8-*-

#python Version:python 2.7.5

Import Sys

Import Nmap

Scan_row=[]

Input_data=raw_input ("Please input hosts and port:")

Scan_row=input_data.split ("")

If Len (scan_row)!=2:

print ' Input error! For example:192.168.18.128 80,443,22 '

Sys.exit (0)

HOSTS=SCAN_ROW[0]

PORT=SCAN_ROW[1]

Try

Nm=nmap. Portscanner ()

Except Nmap. Portscannererror:

Print (' Nmap not Found ', Sys.exc_info () [0])

Sys.exit (0)

Except

Print ("Unexcepten error:", Sys.exc_info () [0])

Sys.exit (0)

Try

Nm.scan (hosts=hosts,arguments= '-v-ss-p ' +port)

Except Exception,e:

Print "Scan error:" +str (E)

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:%s\tstate:%s '% (port,nm[host][proto][port][' state '))
