How to open a new console from python script and be able to manage it

Question

I am writing a script that needs to be able to open a separate console window and read and write to it(on Windows). I want to use telnet and ssh from new consoles and the main console use as a manager

Right now i was trying thoes things:

main file

import subprocess as sp from getpass import getpass import telnetlib import multiprocessing as mp import os def run(command): cmd = sp.Popen(command.split(), sp.PIPE) com, err = cmd.communicate() print(com,err) if __name__ == "__main__": login = input("Podaj login: ") password = getpass() ip = "10.74.119.252" command = f"python LogInConsol.py {ip} {login} {password}" process = mp.Process(target=run, args= (command,)) process.start()

LogInConsol file

import telnetlib import subprocess as sb import sys argv = sys.argv ip = argv[1] login = argv[2] pw = argv[3] # tn = telnetlib.Telnet(host=ip, port= 23) # tn.read_until(b"login: ") command = f"cmd.exe start /k telnet {ip}" cmd = sb.run(command.split(),sb.PIPE) com, err = cmd.communicate()

But the behavior is such that everything happens in main consol window(from which i start program)

UPDATE

This started to work as i wanted it to.

Main.py

from subprocess import Popen, PIPE, CREATE_NEW_CONSOLE from getpass import getpass import telnetlib import multiprocessing as mp import threading as th def run(command): cmd = Popen(command, PIPE, creationflags=CREATE_NEW_CONSOLE) com, err = cmd.communicate() print(com,err) if __name__ == "__main__": mp.freeze_support() login = input("Podaj login: ") password = getpass() ip = "10.10.10.10" command = f"python LogInConsol.py {ip} {login} {password}" process = mp.Process(target=run, args= (command,)) process.start() input("Wait ")

LogInConsol.py

import telnetlib import subprocess as sp import sys argv = sys.argv ip = argv[1] login = argv[2] pw = argv[3] print(argv) tn = telnetlib.Telnet(host=ip,port=23) red = tn.read_until(b"username: ") print(red)

Could try wshshell:

1. pip install pywin32-221-cp36-cp36m-win_amd64.whl 2. python.exe pywin32_postinstall.py -install (DOS command line)

in script:

 import win32com.client WshShell = win32com.client.Dispatch("WScript.Shell") WshShell.run("cmd")

I am testing it and i may work. Can you tell me how to get to input and output of new console ?

take a look at the answer to this question : stackoverflow.com/questions/6732543/… im not too familiar with the library myself so the shell.echo seems to be the answer

It's hard for me to wrap my mind around this api, the example is not very accurate. Still problem is not solved.

try using subprocess.communicate. more here: stackoverflow.com/questions/25815078/… also subprocess.check_output will give the output of the subprocess call. You must call it correctly, in your example script you are not. try this documentation : docs.python.org/2/library/subprocess.html

Could this be a case of the XY problem? You need to connect via telnet or ssh, but do you really need that console in between?

You can make telnet connections in python using telnetlib and ssh ones with paramiko.

What i want is to start connection from main console but manage the rest from the new one
