The problem at thi moment is to start the server when it's offline.
I now it need to be done through the shell. But I don't know how.
I'm programming in php.
I have already several colocated servers running. But it need to be possible to send a command on my websever to the gameserver(another colocated server) to startup the gameserver.
I'd check out xml-rpc (http://www.xmlrpc.com/). Don't worry about doing anything in perl if you don't know much about perl. Anything you can do in perl can be done in PHP. xmL-rpc is nice as it defines a clear interface between talking entities (i.e. servers), is very lightweight, has PHP bindings, and can be performed over a secure channel. It's *almost* as easy as wrighting a script for location execution, but it happens on a remote box...almost .
