http://code.google.com/p/whmtools/ This is a project I've been working on for quite sometime now. It's a php script I've come up with to make my life easier. My webhosting company now has 20 servers. It does a fairly simple job, poll cpanel servers for a list of accounts and allows for you find what domain or user is on what server. I know there are other scripts/applications (whmadmin for example) out there that do very similar jobs. But I was working on this script long before I heard about them. I'm only doing this to help those that only have a few servers and do not feel comfortable dropping a sum of cash for a product that does a very simple task. Its very alpha right now. So if you want to help develop it, it may take a bit of massaging to get it to work for you. whmtools is free and open source and I'll provide as much support as possible. But if you feel more comfortable paying for software that does about the same thing, use whmadmin (http://www.whmadmin.comf).
