Hello,

For reasons that I don't want to go into here, I have recently  
downgraded my principal FreeBSD server from 6.1 to 4.11-RELEASE. I  
did this by installing a fresh copy of FreeBSD 4.11 on a clean HD,  
and then I rsync'd all of my data over.

Everything has been working fine, until I tried to SSH to the box  
this afternoon. While everything was working fine this morning, now  
sshd hangs up immediately on all clients that attempt to connect. In / 
var/log/messages, I see errors like this for every ssh connection  
attempt:

May 31 15:21:06 redefine sshd[8543]: error: ssh_dss_sign: sign failed
May 31 15:21:06 redefine sshd[8543]: fatal: mm_answer_sign: key_sign  
failed

Google hasn't enlightened me at all. This was *just* working a few  
hours ago, and now, nada. Does anyone on this list have any ideas?

Thanks,
	-Andy Reitz.
