So you're not alone. I had my IP changed several times, my servers are only hosting personal data. But I'm still seeing bruteforce attemps in my logs. Here's something I use on my servers. In cron, every 5-10 minutes, that should do it. Of course, if you're running *BSD, pf is way more interesting to do that. Perhaps could be better to use something standard as fail2banhttp://www.ducea.com/2006/07/03/using-fail2ban-to-block-brute-force-attacks/? _______________________________________________ Full-Disclosure - We believe in it.

If you have iptables it has ways you can do this throttle too many connections within a specified period. I much prefer using something such as this over third party software. I'm sure you can do this in PF however I'm not familiar with it enough to be certain (I'd be surprised if you couldn't however). _______________________________________________ Full-Disclosure - We believe in it.
