public static final void chargenUDP(String host) throws IOException {

    address = InetAddress.getByName(host);
    client = new CharGenUDPClient();

    client.open();
    // If we don't receive a return packet within 5 seconds, assume
    // the packet is lost.
    client.setSoTimeout(5000);

    while (packets-- > 0) {
        client.send(address);

        try {
            data = client.receive();
        }
        // Here we catch both SocketException and InterruptedIOException,
        // because even though the JDK 1.1 docs claim that
        // InterruptedIOException is thrown on a timeout, it seems
        // SocketException is also thrown.
        catch (SocketException e) {
            // We timed out and assume the packet is lost.
            System.err.println("SocketException: Timed out and dropped packet");
            continue;
        } catch (InterruptedIOException e) {
            // We timed out and assume the packet is lost.
            System.err.println("InterruptedIOException: Timed out and dropped packet");
            continue;
        }
        System.out.write(data);
