Can not use SSH after renaming the device - 3640 Router

Used SSH to change the device name, wrote the config and logged out of the box. When I attempted to use SSH to get back into the box, it would not connect. I removed the old keys and I attempted to create a new key, but I keep recieving this error message "Signature Creation Failed Status -1" Any suggestions?

Duane,

You are running into Bug ID CSCsa83601.

Workaround:

Set the key pair name to the key name, as shown in the "show crypto key mypubkey rsa".

ip ssh rsa keypair-name

Example:

test#show crypto key mypubkey rsa

% Key pair was generated at: 13:31:48 UTC Apr 8 2005

Key name: test.example.invalid

Usage: General Purpose Key

Key is not exportable.

Key Data:

xxx

% Key pair was generated at: 13:32:28 UTC Apr 8 2005

Key name: test.example.invalid.server

Usage: Encryption Key

Key is not exportable.

Key Data:

I had that problem on my PIX. Did you try "ca zeroize" then generating them again?
