Simple 2911 Question

Chris White
Level 1
Level 1

We have a new 2911 that needs to be configured, unfortunately it's at a remote site.  I had my hands and eye guy install the following config:

Current configuration : 944 bytes
!
! Last configuration change at  17:24:09 UTC Mon Feb 28 2011

end

Router#

Now, I do get a dhcp ip on the G0/0 interface and I can ping it from my remote network and the local router as well as the local lan.  The hands and eye guy is able to telnet from the local lan but I am unable to telnet from either my remote lan or the local router    The only error I receive is "connection refused by remote host".  All lines are clear so I have no conflicts with multiple telnet sessions.

Any help is appreciated.

Thanks

hi chris,

further adding to andrew's commen, kindly add the "login" command under line vty.

Hi Chris,

Below is how line vty 0 4 needs to be configured.

Router(config-line)#line vty 0 ?
<1-4> Last Line Number

Router(config-line)#line vty 0 4
Router(config-line)# password admin2
Router(config-line)# login


And also you can create access-list for security bindings. Below is the sample config as per best practices.

access-list 23 permit 10.10.10.0 0.0.0.255
access-list 23 permit 10.20.20.0 0.0.0.255
access-list 23 permit 10.30.30.0 0.0.255.255

Router(config-line)#line vty 0 4
Router(config-line)#access-class 23 in


Hope this helps you.

Please rate the helpfull posts.

Hi,

The hands and eye guy is able to telnet from the local lan but I am unable to telnet from either my remote lan or the local router

If telnet is working from local lan then it's not an authentication problem but 2 things:

1) did you post complete running?

2)where are you trying to telnet from ---> just draw the topology with the addresses( modified for security reasons of course)?

3) are you using the same credentials as the eye guy?

It is looking more like a routing or ACL problem between your endpoint and the router you're trying to telnet in.

Regards.

The 2911 is in Mexico and I am in Dallas and since I can ping from the desktop in Dallas, then we know the routing is working.  The config I posted is the full config so there are no ACL's or any security on the 2911.  Still waiting for the onsite guy to add the vty config.  I have tested the config I posted on a 2811 on a seperate LAN segment in Dallas and verified that it works.  Thanks for the help so far, will repost once the vty is configured.

*** UPDATE ***

Using the vty config doesn't help.

There has to be something on the 2911 that needs to be turned on.  This is a very simple config and has seved me will when trying to configure a remote router.  Jsut dont' understand why it's not working on a 2911.

Can you post the config after making the changes to "line vty"

Hi,

Can you post the output of your ping and telnet to the router.

From which OS are you telnetting.

Can you also sniff on your computer while telnetting and put the pcap file here.

Regards.

Alain.
