We changed the hostnames on over a dozen others without any issues. I tried re-generating the keys to no avail. Jon Wolberg Systems Engineer Virtacore Systems Inc.

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?
