How to setup telnet server in python

Question

How can I build a telnet server in python? What tools should I use? I've seen a lot of code on the internet but nothing worked. It needs to run a python file as a shell with no login prompt. How can I do that?

Answer 1

The telnetlib module provides a Telnet class that implements the Telnet protocol.

A simple example illustrating typical use:

import getpass
import telnetlib

HOST = "localhost"
user = input("Enter your remote account: ")
password = getpass.getpass()

tn = telnetlib.Telnet(HOST)

tn.read_until(b"login: ")
tn.write(user.encode('ascii') + b"\n")
if password:
    tn.read_until(b"Password: ")
    tn.write(password.encode('ascii') + b"\n")

tn.write(b"ls\n")
tn.write(b"exit\n")

print(tn.read_all().decode('ascii'))
