As for limiting ssh access only to those who need it, how would that be done and how can I restrict on IP and user? I've found this page http://doc.trustix.org/cgi-bin/trustixdoc.cgi?Restrict_SSH_Per_User which explains about allowing only certain users. It's cool. Now, what would be the user/ip combi approach?
I make my firewall do that.
