Cisco 2621XM - IOS Version 12.4(25d) Login failed [user: ] - Does not show "user" when connecting through telnet and trying with wrong "user and password" - Valid user works perfect.

Hi, Everyone!

 

Cisco 2621XM - IOS Version 12.4(25d)  Login failed [user: ] - Does not show "user" when connecting through telnet and trying with wrong "user and password" - Valid user works perfectly.

 

When a failed login attempt is tried through telnet connection the field user does not show the user that was typed and I need this info in other to do some troubleshooting on my network. 

 

Log messages inside the router: 

 

003123: Sep 28 11:29:39.430 ART: %SEC_LOGIN-4-LOGIN_FAILED: Login failed [user: ] [Source: 10.0.0.123] [localport: 23] [Reason: Login Authentication Failed] at 11:29:39 ART Thu Sep 28 2017

 

003127: Sep 28 11:30:11.818 ART: %SEC_LOGIN-5-LOGIN_SUCCESS: Login Success [user: pepe] [Source: 10.0.0.123] [localport: 23] at 11:30:11 ART Thu Sep 28 2017

 

Thanks a lot!

Re: Cisco 2600 Login failed [user: ] - Does not show user when sending Syslog messages

if you log into the device itself and check the log it should tell you what user iD last attempted

Ey, Denis! That's exactly the problem. Even in the router itself, we are not getting the users registered for a failed login attempt.

 

Thanks for your answer!
