Logged in from another location

I just noticed that when you join an offline server twice with the same account (name), the already logged-in user gets kicked. What is up with this??? It does not make sense to kick the player that was already on the server to let someone new with the same name in. I am currently writing a (desperate?) plugin which handles the login event to kick the player that tries to log in, but obviously not everyone can write plugins like that. I believe this is a bug which should be fixed soon, before annoying people start "kicking" players on servers by joining the server with their name.

EDIT

Temporary fix I use:

Code:

    @Override
    public void onPlayerKick(PlayerKickEvent event) {
        if (event.getReason() == "Logged in from another location.") {
            event.setCancelled(true);
        }
    }

    @Override
    public void onPlayerLogin(PlayerLoginEvent event) {
        for (Player p : plugin.getServer().getOnlinePlayers()) {
            if (p != event.getPlayer() && p.getName().equalsIgnoreCase(event.getPlayer().getName())) {
                event.setResult(Result.KICK_OTHER);
                event.setKickMessage("Another player with your name is already on this server!");
                break;
            }
        }
    }

 

The Bukkit team does not fully endorse offline servers, this is how it is coded by Mojang, and they will most likely not be changing this behaviour. If you want your server to be secured against users doing actions such as this, run in online mode and don't support piracy.

 

Expected reply, although you are completely right.
I still find this behaviour kind of odd, even for a legit online server.

 

It's standard behaviour in most online games, actually. And if your server were set to online mode, this wouldn't happen, because you can't just randomly change your username when signed in.

 

You can log in with the same account on a different computer, but not sure if this is possible through the webserver.

 

I think xAuth blocks this.

 

can someone please write a simple plugin or a tutorial to fix this problem.

 

Yea, can you make a plugin with this?
