Greetings.
Short and to the point - Is there any way to get some sort of identifier , from where a servercommand came from?
Currently using   object OnServerCommand(ConsoleSystem.Arg arg)  
But arg.Connection is always null for me . 

 I would like to monitor the IP from where a command was send from ...  someone any idea?  

arg.Connection is for players, consider using OnRconCommand

well then i suppose it is done via extension or something and there would be no way to detect it unless the extension provides code
