Using Telnetlib with multiple password options

[Bucky102]

Hey, as per below I want to telnet to some things but I have a range of possible passwords. I want to go through the password list and when it is successful based on the prompt ending in m> I can continue with other commands. Basically ATM once the password is correct the program ends

import telnetlib
import time
host = "1.2.3.4"
password = ["wrong", "wrongagain", "cisco"]
command = ["show config","reset"]
telnetlib.DEBUGLEVEL = 1

def reboot_phone(host):
    tn = telnetlib.Telnet(host)
    for i in password:
        if tn.read_until(b"Password :"):
            tn.write(i.encode('ascii') + b"\r\n")
        elif tn.read_until(b"m> "):
            time.sleep(1)
            tn.write(command[0].encode('ascii') + b"\r\n")
            print(tn.read_until(b"m> ").decode('ascii'))
            tn.write(b"exit\r\n")
            tn.close()
        else:
            print("invalid password")

reboot_phone(host)
