实现Python端口扫描加服务探测

一、流程

首先，让我们来整理一下实现Python端口扫描加服务探测的流程：

步骤 描述
1 输入目标主机
2 确定端口范围
3 扫描端口
4 探测服务

二、代码实现

1. 输入目标主机

target = input("Please enter the target host IP address: ")

2. 确定端口范围

start_port = int(input("Please enter the starting port number: "))
end_port = int(input("Please enter the ending port number: "))

3. 扫描端口

import socket

for port in range(start_port, end_port+1):
    client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    client.settimeout(0.1)
    code = client.connect_ex((target, port))
    if code == 0:
        print(f"Port {port} is open")
    client.close()

4. 探测服务

import socket

def service_scan(port):
    try:
        service = socket.getservbyport(port)
        print(f"Port {port} is for {service}")
    except:
        print(f"Port {port} is not associated with any service")

for port in range(start_port, end_port+1):
    service_scan(port)

三、类图

classDiagram
    class Developer {
        - name: string
        - experience: string
        + Developer(name: string, experience: string)
        + teachWhite(code: string): void
    }
    class White {
        - name: string
        - level: string
    }
    Developer --> White

四、关系图

erDiagram
    White {
        string name
        string level
    }

结尾

通过以上代码和流程，你可以实现Python端口扫描加服务探测的功能了。希木这篇文章对你有所帮助，如果有任何问题，欢迎随时向我提问。祝你学习顺利！
