telnet to a device under tacacs management

[kang18]

Hi,

I am trying to telnet a device under a tacacs management. but it seems I am missing something. When i run the code it just stop and terminate the program.

import getpass
import telnetlib

host = "10.107.1.2"
user = raw_input("Enter your username: ")
password = getpass.getpass()


tlnt = telnetlib.Telnet(host)

tlnt.read_until(b'TACACS Username: ')
tlnt.write(user.encode('ascii') + b'\n')

if password:
	tlnt.read_until(b'TACACS Password: ')
	tlnt.write(password.encode('ascii') + b'\n')
	
tlnt.read_until('>')	
tlnt.write(b'enable \n')
tlnt.write(b'exit \n')

output = tlnt.read_all().decode('ascii')

print output
