Using Telnet in Python


To make use of Telnet in Python, we can use the telnetlib module.

That module provides a Telnet class that implements the Telnet protocol.

The Telnet module have several methods, in this example I will make use of these:
read_until, read_all() and write()

Telnet Script in Python


Let’s make a telnet script

import getpass
import sys
import telnetlib

HOST = "hostname"

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()

At ActiveState you can find more Python scripts using the telnetlib,
for example this script.

For more information about using the Telnet client in Python, please see the
official documentation.
