This is an announcement from valve about the new cs 1.6 update:
PHP Code:
"Added privilege checking to command execution. Commands originating outside of the client are now only able to execute commands that are considered to be safe. Commands such as 'connect', 'bind', 'quit' and certain cvars such as 'cl_filterstuffcmd' are now only executable by trusted sources."
does somebody knows what they mean by "trusted sources"? there isn't official servers for cs 1.6 so I'm guessing you need to apply to be trusted, does somebody knows anything about that?
