scans and add a firewall rule to temporarily block that ip. Does anyone know what tool that is?

Also disabling remote login as root should help.

Sweet, actually this looks more like what I wanted, but rackspace said wasn't available. This bans the ips if there are a lot of password failures.

There is also another tool which bans ips for port scans. I think it's been discontinued, but perhaps there is another one out there?

I think that was portsentry. http://sourceforge.net/projects/sentrytools/
