6500 MSFC wont accept enable password

This router has a very restrictive access list for vty 0 4. All the machines that could possibly access it have been checked for hackage. I still have enable access to the switch. I still have snmp access and no config changes have apparently been made to the MSFC. It seems real unlikely that it has been broken into. The last config written to tftp shows the same secret as in 2 old configs.

I'm interested in any and all suggestions as to how to proceed from here... any known exploits any explanations or any ideas or any tricks to try would be greatly appreciated.

Thanks

Ron

Re: 6500 MSFC wont accept enable password

try the password you think it should be with a space at the end, then try 2 spaces, etc.

Things that can happen

1. people who use the ? every time they work through a command can end up with space/s at the end of their password and they become part of the password.

2. copy/pasting config in can add space/s to the end of a password

3. entering the coomand incorrectly like enable password secret cisco (where it should have been enable secret cisco) creates a password with embedded space of "secret cisco".

It can be multiple spaces so if one doesn't work try more progressively. You might be able to see the spaces on the saved config if it is not encrypted.
