    Für ein Mindestmaß an Rechtschreibung, Interpunktion und Majuskeln!

    Ok erst mal danke soweit für die Hilfe.
    Aber leider werden die Adressen nicht angezeigt die auf meine Datein zugreifen.

    Wollte eine Tool schreiben das z.b. bei COD MW2 verwenden hätte können.
    Wenn ich der Host bin greifen ja alle auf meine Server Dateien zu, und dann wenn ein Cheater im Spiel ist das ich "nur" seine IP Adresse Blocken muss damit er keine Verbindung mehr hat.
    Aber leichter gesagt als getan, ich weiß.....
