A lot ... as far as the filter table and sshcheck is concerned,
iptables -N sshcheck;
iptables -A sshcheck -m recent --name sshcheck --seconds 60 --update -j DROP;
iptables -A sshcheck -m hashlimit --hashlimit-name sshcheck \
--hashlimit-mode srcip --hashlimit 4/min --hashlimit-burst 4 \
-j RETURN;
iptables -A sshcheck -m recent --name sshcheck --set -j DROP;
