I am trying to telnet to a router that is configured with a BRI interface (using Ip Unnumbered Ethernet 0) and Ethernet 0 (exampe of ip: 22.214.171.124). The result when I telnet to 126.96.36.199 is:
Could not open a connection to host: connection failed.
There is no one logged into the router. The router was running IOS 11.*, the same problem exsist, so I upgraded the software to 12.1.7, and problem is still there.
The router functions correctly, it routes just fine, you just can't telnet.
The router is a 3620.
Any help is welcomed!
Solved! Go to Solution.
to be pretty sure of what the problem could be is to explain the error displayed when u enter d command
i want you to know it could be non connectivity problem or simply the fact that you are yet to enable enable password or secret,without this been enablepassword or secret configured, telnet becomes partial functional..
A cisco, by default, will not allow a vty connection. You will need to do the following
router(config)# line vty 0 4
what is your real error message when you telnet on it ?
I don't think it missed passowrd on vty line . In the case, router will respond you " password is not set "
If you have verified that no access-list is set, make sure you have set a default route.
(eg. ip route 0.0.0.0 0.0.0.0 188.8.131.52)
I think the other gentleman hit it on the head with "line vty 0 4" but the other thing is you need to make sure the computer you are telnet'ing from can actually get to the router. See if you can ping it from your command line. I had a similar issue with a pc that had two nic cards. One was set for a class B address and accessed the Intranet/Internet. The other card I had to set up with in the subnet of the router E0 port so that I could telnet to it.
I think the problem would have been due to the missing line vty
line vty 0 4
You can hyperterm using the console cable and make these changes and try
