    Hey so a player is trying to login while using a vpn called FastVPN but gets this error (client sided) which might have to do with the rs2 login decoder but im not sure what and how.

    It's telling you the exact error... your byte MACa is null..
    assuming MACa is macaddress you need to edit the way your mac address is being set for his os type.

    Someone was having a problem with Kronos a couple days ago with mac address aswell (https://www.rune-server.ee/runescape...gin-crash.html)

    To allow VPN users: In the client I recommend adding a try exception when sending the mac address byte, and if there is an exception send the bytes {0} instead of the players mac address.

    Can you help me with this code because it makes sense.

    public byte[] getMACaddress() {
    try {
    InetAddress ip = InetAddress.getLocalHost();
    NetworkInterface network = NetworkInterface.getByInetAddress(ip);
    return network.getHardwareAddress();
    } catch (Exception e) {
    e.printStackTrace();
    }
    return null;
    }

    Try this:

    Code:
    public byte[] getMACaddress() {
    try {
    InetAddress ip = InetAddress.getLocalHost();
    NetworkInterface network = NetworkInterface.getByInetAddress(ip);
    return network.getHardwareAddress();
    } catch (Exception e) {
    e.printStackTrace();
    }
    return "0".getBytes();
    }

    Shouldn't use this tho, should find a way to return the proper mac ID. this leads to a lot of issues.
    But here's it spoon fed and fixed.
    If multiple people have invalid mac's they will be set to 0 which may limit your login usages if you are using runesource. runesource uses macid to not allow more than 2 clients, with this if two people have a "invalid" mac thats set to 0, next person with an invalid mac id wont be able to login.
    Cheap fix.

    If you want a proper fix my suggestion is to learn how to pull mac address by each os type and to make a proper method to pull that mac id because each machine's os pulls mac id's differently.
    https://stackoverflow.com/questions/...es-mac-address

    identify the machines OS
    use commands to run a "ipconfig" or "ifconfig" or whatever to return the value of mac id.
    Use that info to store and send that macid.

    That might be one way of doing it.. And also a cheapfix would be to stop VPN all together by macbanning bytes 0 to avoid exploits.
