I have a cisco 1941 router just configured but no matter how I go about configuring the telnet, it seems not to work.

It has interfaces already set up and systems can browse through it in the office. It has two interfaces WAN and LAN configured with Ip Addresses and the LAN interface with other sub interfaces with IP address configured on them.

I have tried setting up the terminal with the command as stated below but it is not working.

Router(config)#line vty 0 ?
<1-1370> Last Line Number
Router(config-line)#line vty 0 1370
Router(config-line)# password P@$$W)RD
Router(config-line)# login

I even tried using the following configuration but yet not working

Router(config)#line vty 0 4
Router(config-line)# password P@$$W)RD
Router(config-line)# login

Everytime I try to connect to the any of the subinterfaces through telnet or the WAN address through telnet, I get the error message

MacBook-Pro:~ User$ telnet x.x.x.x
Trying x.x.x.x...
telnet: connect to address x.x.x.1x Connection refused
telnet: Unable to connect to remote host

Please what am I getting wrong here?

  • Are you in the same LAN of the router? Commented Apr 3, 2014 at 8:51
  • Yes... on the same Lan. The system I am connecting from is connected to the subinterface of the Lan. Interface GigabitEthernet 0/1.1

  • If you are using subinterfaces I guess you are using VLANs, is the switch properly configured? If you prefer we can switch this conversation on the chat Commented Apr 3, 2014 at 9:05
  • @OlanrewajuT Do you have any ACLs setup on the Router?

The issue has been resolved. When I checked the running configuration on the router, I noticed I have the line below under the line vty 0 4

access-list class 23 in

All I had to do was to negate the command and everything went back to normal.

Thanks all for your support.

    If this router is sitting on the Internet edge, are you sure you want to negate your ACL that gave some additional protection to you? Perhaps updating access-list 23 is more appropriate. Commented Aug 11, 2014 at 8:00
  • How do you mean? Please explain! The access list has no function on the router.

  • @OlanrewajuT, the access-list class 23 in on a VTY applies an ACL limiting access to the VTY's. It is best practice to use them to limit management access to the device.

-- at the running configuration in the line vty interface check if the transport input is set... if it says tansport input none, then go to the line vty interface and write the following command transport input telnet.


run this command in your router

conf t
line vty 0 4
transport input all

Cisco Router as Cisco access Server: Remember the CAB-OCTAL-ASYNC cable is rolled. Therefore, you can connect each cable directly to the console ports of devices with RJ-45 interfaces. Anyway, when you config the ports of this OCTAL-Async you need to start from port 2033 down to 2065 not 2001, 2002, or 2003.

Like this:

AS(config)#interface lo0 AS(config-if)#ip address AS(config-if)#exit AS(config)#ip host r1 2033 AS(config)#ip host r2 2034 AS(config)#ip host r3 2035 AS(config)#ip host sw1 2036 AS(config)#ip host sw2 2037

then if this works after testing it.

Try setting up the password

Hope this answers or others might have some issue as well.
