Setting up Telnet

I am trying to setup Telnet on my Cisco 2900 Series K9.  I have read a bunch of articles to see if what I am doing wrong.  All the articles are pretty much the same thing:

Router>enable
Router#configure terminal
Router(config)#enable secret password
Router(config)#service password-encryption
Router(config)#line vty 0 4
Router(config-line)#password password
Router(config-line)#login
 
I have done this a bunch of times and still receive the error could not open connection to the host on port 23 connect failed.  Here is my show line:

Here is my vty 0 4 :

 

 

line vty 0 4
 access-class 23 in
 privilege level 15
 password password
 login local
 transport input telnet
 transport output telnet ssh

 

Any ideas whats wrong?  Thanks!

the first thing that pop out

the first thing that pop out for me is the  access-class 23 in, can you try and remove that and see if it works.

 

Secondly on your show line, I do not see the vty lines 0 - 4 at all, it seems they begin from 644 to 659...which is kind of weird for me. If your access-list is not blocking, I would suggest you configure your Vty line as:

line vty 644 659

which seems odd but would actually resolve your issue because those are the lines available on your device.

Get rid of the login local

Get rid of the login local under the vty , that is trying to call a locally defined username and password which you don't appear to be using .  Also you have an ACL on the vty so whatever address range you are trying to telnet in from must be allowed in that ACL.
