As that host is not supposed to get any connection, I would put a Banner 
entry on sshd_config saying "This is not the drone you were expecting to 
log into" (or a more elaborate phrase of your email :P).
That would at least hint that instead of panicking we should go to irc 
to bug you for crashing the network service ;)
