[code=Java]
socket = serverSocket.accept();
socket.getRemoteSocketAddress(); // liefert die IP und den Port des Clients, der sich mit dem Server verbunden hat
[/code]
Jetzt wird das mit der JList alles ein klein wenig komplizierter, denn jetzt musst der JList nicht einfach nur einen Wert geben, sondern ein Objekt, welches mehrere Werte beinhaltet (IP und Progress). Ein Objekt deswegen, weil ja IP und Progress in Relation stehen.
Aber möglich ist das alles, irgendwie
