Well the one i bought from
No1Servers - Home works like this.
Its all worked through online. You go to:
No1Servers Game CP - Login
Then once your there you can log in.
After logged in you go to your file manager, upload your server.
Then once your server is uploaded, there is a box that says, Rune - Stop - Restart. And some numbers above it. The numbers above it are the ip address for people to log onto your server. And then the port is next to it (always 43594) Then you click run, to turn it on, You click Stop to turn your server off, and Restart, to restart it.
Its very simple and a very easy thing to help out your RSPS.
