Am running a example script of telnet lib and observed that the script is printing out on to the console.

import getpass
import sys
import telnetlib

HOST = "xxxxxxxxx"
user = raw_input("Enter your remote account: ")
password = getpass.getpass()

tn = telnetlib.Telnet(HOST)

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

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

print tn.read_all()

and the it return nothing The Target is windows machine and source where the script is executed is linux.

Did you try to manually telnet to the target machine, and did you control the prompts (I had to change the Password prompt for my BSD machine)? – Serge Ballesta Feb 27 '19 at 11:27
Yah i tried manually. Changing password prompt means? – Sagar Feb 28 '19 at 04:34
My system has an additional (variable) string between `Password` and `:`, and no space after the colon. So I had to use `tn.read_until(":")` before `tn.write(password + "\n")` – Serge Ballesta Feb 28 '19 at 06:43
Thanks Ballesta, that helped. – Sagar Feb 28 '19 at 10:27
