I apologize in advance for asking a question that has been answered in a thousand threads and tutorials. In theory I know what to do, but still cant get it to work. I've got a tiny station in Kerbin orbit, and a spacecraft that I'm trying to dock with it. Both have clamp-o tron ports, one of them shielded. The actual rendevouz is not the problem. I have both craft aligned, but when I bring the docking ports close together, or even have one inside the other, the two will at some point just bounce off. From the KSP wiki I learned that they are supposed to magnetically clamp but that doesnt happen. One thing I noticed is that when I set the approaching ships docking port to "control from here", nothing really changes. I'm not sure whats supposed to happen, but apparently its important. Hope some kind Kerbal can point out my mistake(s). Thanks.
