python高效端口扫描

这次我们使用python-nmap包进行计算机端口扫描，有liunux基础的同学一定知道nmap的强大，不废话，上代码：

# coding=utf8

import nmap
import sys

def main():

    scan_row = []

    input_data = raw_input('Please input hosts and port: ')
    scan_row = input_data.split(" ")

    if len(scan_row) != 2:
        print(" Input error. Please input again.")
        sys.exit(0)

    hosts = scan_row[0]
    port = scan_row[1]

    try:
        nm = nmap.PortScanner()
    except nmap.PortScannerError as e:
        print('Nmap not found. e: %s' % e)
        sys.exit(0)

    except Exception as e:
        print('Unexpected error. e:%s' % e)
        sys.exit(0)

    try:
        nm.scan(hosts=hosts, arguments=' -v -sS -p ' + port)
    except Exception as e:
        print('Scan error.')

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

if __name__ == '__main__':
    main()

这里我们pip 安装python-namp包，具体的详细方法请参考官网源码包中实例。
