使用Python让用户登录到网络中的每台计算机

Question

我正在寻找一种方法，可以监视用户是否使用Python登录到网络中的某些计算机，并将数据返回到一台计算机。理想情况下，我希望能够通过ip地址检查每台计算机，并查看用户是否登录。计算机有Windows

所以我想构建一个这样的函数：

IP_ADDRESS = '123.123.123.123'
check_user(IP_ADDRESS)

输出： 登录用户：Ed

或

输出： 登录用户：不适用

Answer 1

您必须像这样准备MS Windows服务：How do you run a Python script as a service in Windows? 您的服务必须打开端口进行检查，您可以使用FastAPI。您可以通过以下方式检查当前用户：https://docs.python.org/3/library/getpass.html#getpass.getuser

Answer 2

下面的解决方案工作得很好

如果有人知道如何使用python命令解锁计算机，请告诉我。我从网上的一个人那里得到了这个代码，并根据我的目的修改了它

如果有人认出了我，让我知道，这样我们就可以给信用。我记不起他的名字了

这是我的服务器

import socket
import argparse
import threading 
import csv



parser = argparse.ArgumentParser(description = "This is the server for the multithreaded socket demo!")
parser.add_argument(' host', metavar = 'host', type = str, nargs = '?', default = socket.gethostname())
parser.add_argument(' port', metavar = 'port', type = int, nargs = '?', default = 9999)
args = parser.parse_args()

print(f"Running the server on: {args.host} and port: {args.port}")

sck = socket.socket()
sck.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

try: 
    sck.bind((args.host, args.port))
    sck.listen(5)
except Exception as e:
    raise SystemExit(f"We could not bind the server on host: {args.host} to port: {args.port}, because: {e}")


def on_new_client(client, connection):
    ip = connection[0]
    port = connection[1]
    print(f"THe new connection was made from IP: {ip}, and port: {port}!")
    while True:
        msg = client.recv(1024)

        # with open('aa.csv', 'w', newline='') as csvfile:
        #     thewriter = csv.writer(csvfile)
        #     thewriter.writerow([msg.decode(),'computer 2'])

        if msg.decode() == 'exit':
            break
            
        if msg.decode() == 'lock computer 1':
            reply = 'lock'
            client.sendall(reply.encode('utf-8'))

        elif msg.decode() == 'open computer 1':
            reply = 'open'
            client.sendall(reply.encode('utf-8'))

        # print(f"The client said: {msg.decode()}")
        # reply = f"You told me: {msg.decode()}"


        # client.sendall(reply.encode('utf-8'))
    #print(f"The client from ip: {ip}, and port: {port}, has gracefully diconnected!")
    #client.close()

while True:
    try: 
        client, ip = sck.accept()
        threading._start_new_thread(on_new_client,(client, ip))
    except KeyboardInterrupt:
        print(f"Gracefully shutting down the server!")
    except Exception as e:
        print(f"Well I did not anticipate this: {e}")

sck.close()
