Accomplishable with minimal modifcations of the example on the SA-MP wiki:

Код:

public OnRconLoginAttempt(ip[], password[], success)
{
    if(!success) //If the password was incorrect
    {
        printf("FAILED RCON LOGIN BY IP %s USING PASSWORD %s",ip, password);
        new pip[16];
        for(new i=0; i<MAX_PLAYERS; i++) //Loop through all players
        {
            GetPlayerIp(i, pip, sizeof(pip));
            if(!strcmp(ip, pip, true) && !PlayerInfo[i][pAdmin]) //If a player's IP is the IP that failed the login AND they aren't an admin
            {
                SendClientMessage(i, 0xFFFFFFFF, "Wrong Password. Bye!"); //Send a message
                Ban(i); //They are now banned.
            }
        }
    }
    return 1;
}

Of course you'll need to replace '!PlayerInfo[i][pAdmin])' with the variable that matches your script/admin system.

I'd HIGHLY advise you use foreach instead if you use that, and if you don't use it, what are you waiting for?
