Use fail2ban to target active abusers using your logs. (recommended) Leverage the cloud with something like: http://iplists.firehol.org/?ipset=firehol_level1 (loaded to shorewall with ipset:hash) to preemptively ban via blacklists - recommended. There are many good blacklists out there - this one is a meta-list and has fast and responsive updates. Snort (in IDS mode triggering a fail2ban rule) is a bit heavier resource-wise but quite useful. Snort in IPS mode is better, but it can impact throughput. (if you are commercial, consider a licence to get the latest rules as soon as they are created/needed.) or use all of them at the same time :) BillK
