Below is my code:

import os
import telnetlib
import re

def telNetCall():
 host  = "xx.xx.xx.xx"
 user  = "admin"
 password = "password"
 enable_password = "enable_password"
 telnet  = telnetlib.Telnet(host)


 telnet.read_until('Username: ', 3)
 telnet.write(user + 'r')
 telnet.read_until('Password: ', 3)
 telnet.write(password + 'r')
 telnet.write('enable' + 'rn')
 telnet.write(enable_password + 'rn')
 telnet.read_until("#")
 raw input("Press Enter to continue...")
 telnet.write("telnet xx.xx.xx.xx" + 'rn')
 telnet.read_until('Username: ', 3)
 telnet.write(user + 'r')
 telnet.read_until('Password: ', 3)
 telnet.write(password + 'r')
 telnet.write('enable' + 'rn')
 telnet.write(enable_password + 'rn')
 telnet.write("show logg"+ "rn")
 telnet.write('exit' + 'r')
 a = telnet.read_all()
 f = open(host, 'w')
 f.write(str(a))
telNetCall()
