Space Game - Multiplayer

Hi,

I am already making my Spacegame and multiplayer isnt working. I am trying to fix it 3 months now but I still cant find any good tutorial or something. Multiplayer is working on Photon Cloud and the problem is that when second player joins the server, he can control his and my ship and I can control my and his ship. Also there appears big lags and the positions are changed.

Here is Webplayer demo: http://galaxon-eu.clanweb.eu/WebPlayer.html

Please tell me what can I do or sent me some script. For player prefab I am using my SSControls (Spaceship Controls) and Rigidbody.
