The predators are the numerous script kiddies (skiddies) and crackers out there that either trying it on, seeking to find yet another server to host their warez, or they're building a massive, high bandwidth botnet in which to strike down those who oppose them.
When I looked at my new herd of servers (okay, 3 isn't really a herd...) I saw a neglected bunch that needed some tender loving care. So all this week I have been looking at what makes them tick and for what purposes they serve. In the process I've been cutting the fat, optimizing and tightening things up. There's still a ways to go but things are already looking better, especially after upgrading the link from 10Mbit to 100. I hope whoever owned those domains I disabled doesn't get too pissed.
Things that need to happen:
- Consolidate servers into a single rack and connect them via a private LAN
- Adjust load balancing to go between all three servers
- Establish a managed firewall
- Upgrade OS and packages on each
I won't feel comfortable until all that is in place.
