SSH no longer functions after hostname change
|
|
Hello-
We recently changed some of our hostnames on various legacy switches to follow our naming convention, and after one change I can no longer SSH to the switch.
I get the below errors on the console with debug ip ssh client running:
Aug 10 11:23:44 EST: SSH5: sent protocol version id SSH-2.0-Cisco-1.25
Aug 10 11:23:44 EST: SSH5: protocol version id is - SSH-2.0-OpenSSH_4.3
Aug 10 11:23:44 EST: SSH2 5: RSA_sign: private key not found
Aug 10 11:23:44 EST: SSH2 5: signature creation failed, status -1
Aug 10 11:23:44 EST: SSH5: Session disconnected - error 0x00
I zero'ized the old keys and re-generated as well as set the hostname back to the original and zero'ized and re-generated to no avail. Nothing shows up on Google and I can find no errata related to SSH access on the version of code we are running.
Has anyone encountered this before? This is a 3750 running 12.2(44)SE2
