Jon,
What is different with respect to software version, SSH config &
platform between this swtich and the dozen others that (could be
seeing a similar problem but) aren't?

Hi Paul-
The funny thing is this is the only switch causing problems. We
changed the hostnames on over a dozen others without any issues.
I tried re-generating the keys to no avail.

Normally all we do is a "crypto key gen rsa" if a hostname changes
and we
continue on... this regens the keys and stops/starts the SSH
process....

Subject: [c-nsp] 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
