If not there are some simple script for rcon attempt I found:

Код:

public OnRconLoginAttempt(ip[], password[], success)
{
    for(new i=0; i<MAX_PLAYERS; i++) //Loop through all players
    {
        if(adminlevel[i] >  3) //If the admin level is greater than 3 then 
        {
            if(!success)
            {
                printf("FAILED RCON LOGIN BY IP %s USING PASSWORD %s",ip, password);
            }
            else
            {
                printf("IP %s logged in to rcon successfully using password %s",ip, password);
            }
        }
        else
        {
            SendClientMessage(playerid, 0xFFFFFFFF, "Only Administrators may use RCON.");
        }
    }
    return 1;
}

If a player who is not an admin try to use /rcon, then kick/ban/banip him. I prefer banip+banname . Hope someone give you a script for this.
