一、安装

python 使用python-nmap来扫描端口信息，首先要在系统中安装nmap，命令如下

yum install nmap

二、使用
使用代码如下：

# coding=utf-8

import sys
import nmap

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

print "input_row: " + input_raw

rows = input_raw.split(" ")

if len(rows) != 2:
    print "input row Error"
    exit()

hosts = rows[0]
ports = rows[1]

try:
    nm = nmap.PortScanner()
except nmap.PortScannerError:
    print "Nmap not fount",sys.exc_info()[0]
    exit()
except:
    print "Unexpected error:", sys.exc_info()[0]

try:
    nm.scan(hosts=hosts, arguments=' -v -sS -p '+ports)
except Exception, e:
    print "Scan erro:" + 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'])

运行：

python test.py

输出：

10.3.15.10-20 80,22,433,3306
