Securing the Server

As if SPAM wasn't enough of a problem, my server has been putting up with dozens of malicious script-kiddies trying dictionary attacks. I counted 23,412 'Illegal user' login attempts in a day and a half - that's gotta be a load on the server, even if all of the logins ultimately fail. So I spent a couple of hours this morning and installed DenyHosts, which is really an excellent tool - it's already stopped three attacks today, before they could get started. It's flexible, too, and can run as a cron job or a daemon. If you run a Unix style server, get this installed. You'll sleep better...
