If I telnet via the network to a 3640 router I immediately see what appears to be 3 failed password attempts.
Password:
Password:
% Bad passwords
Connection closed by foreign host.
If I telnet via serial connection to the console port it works fine. I have tried removing all unnecessary commands from the 'line vty' interface but it's still doing. I've also tried from several different machines with different OSes. Thanks for any help.

First let us clarify something. When you connect to the console port it is not telnet. You are establishing a serial connection to a hardwired port and not a telnet.
There recently was a posting about a similar issue. Look at this link and see if it is any help to you:
If it does not help then there are a couple of things that you could tell us that would help us understand the issue and perhaps to make some suggestions:
- has telnet worked before and then stopped working? or is this a fairly new router and telnet has never worked?
- can you post the relevant parts of the config of the router (especially the aaa if it is configured and the configuration of the vty lines).

Hi Rick, thanks for the response. I did the same thing as mentioned in the other thread and it worked. Just did the no login and logged in with no password, then reissued the login command and logged in fine with the password.
As for the misnomer about telnet, you're right, but I didn't mention I was telneting to a terminal server which passes through to the console.
Thanks again.
