SSH Issues on Cisco Catalyst 3750E

[richardfinnie]

Hi All,

I upgraded one of my WS-C3750E-24PD this AM and am now experiencing a strange issue. When trying to connect to this stack via SSH I am unable to (receive "connection refused"), and in the switch logs I see the following error message:

Mar 22 08:39:26 CST: SSH2 0: RSA signature generation failed, status 545

Mar 22 08:39:26 CST: SSH2 0: signature creation failed, status -1

Anyone seen this before? any ideas?

Thanks,

Rick

Try zeroizing the key and regenerating RSA again

"crypto key zeroize rsa"

"crypto key generate rsa"

Incase you find this post helpful. Do rate it.

@Sebastian - That was actually the first thing I tried, as i had thought that maybe the keys got screwed up in the image upgrade. The really unusal thing is that several other stacks went smoothly without this issue.

I guess a call to TAC may be order for this.

Richard I guess so, time for an expert call from TAC.
