You mean the SSH host key. Hobbit cannot do that currently, since it
doesn't know about the SSH protocol other than to expect the "SSH-..."
banner when it connects to an SSH service.

One could probably pick out the necessary pieces of code from the 
OpenSSH client to build a checker for this. That would be useful, 
because it would also eliminate the warnings that OpenSSH logs 
when Hobbit checks the service.

Ouch - whatever you find out, I'll be interested to hear about it.
My server setup looks disturbingly much like yours, so if there is a
new root exploit out there, I'd like to know.
