having a telnet login issue

[DarylPienta]

1st let me say I am not the most experienced CCNA out there.

Here's my problem. I am trying to telnet into a router from my workstation. I was using the wrong password earlier in the day, but resolved this. My boss can telnet into the router from his workstation but we still cannot log in from mine. When I telnet it prompts me for the password so I know I'm communicating with the router

there are no access lists denying me or anyone access at this time. I have tried a few different interfaces and it just will not let me in.

Has my IP address been locked out in some way. Anyone have any suggestions. Also after I try and fail 1/2 dozen times both my boss and I cannot log in, but the boss seems to be able to after a period of time, not sure how long that time period is though.

Thanks in advance for any advice

Is the router using aaa for authentication with an authentication server or is the router authenticating locally?

If authenticating with an authentication server it could explain the difference in your boss logging in and you not.

If it is not authenticating with an authentication server then there must be some other explanation. Is it possible that you have the caps lock engaged on your keyboard?

If the telnet is from the workstation of your boss can you login? If the telnet is from your workstation can your boss login?

Are you very sure that there is no access list or access class configured that is controlling access?

I am not aware of anything in IOS that counts how many incorrect attempts to login or that would lock out anything based on failed login attempts.

Hi, I have never heard of a lockout feature based on ip address unless you are going through a tacacs server and have configured the number of attempts, ect.

Make sure that you do not have 'access-class xx in' on the vty lines tying it to a access-list. Or something like ip telnet source in the config. Maybe a post of your config would help.

Have your boss login and do a show users and see if all your vty sessions are being tied up for some reason , if they are then you should be able to clear them out .

Well we finally got back into the router. We ended up doing a password recovery which seemed to fix the problem.

not sure why it was tempermental, but obviously something was corrupted

Thanks for the suggestions
