Yep, sure, could also use hosts.allow and hosts.deny. Personally, I 
prefer to filter at the firewall level against source IPs, but of course 
that's just my preference :)

David - sorry, I don't speak fluent sed, but I assume you're suggesting 
limiting the protocol to SSH2 only? ie, editing /etc/ssh/sshd_config to:


#   Protocol 2,1
     Protocol 2
