Mina Linux向广播地址192.168.0.255发送UDP广播失败！

Question

Windows下可以正常广播，但是Linux下就不行。

 // UDP
            connector = new NioDatagramConnector();
            connector.getFilterChain().addLast("codec",
                    new ProtocolCodecFilter(ConfigMgr.getInstance().getKJLJProtocolCodecFactory()));

            // 设置连接超时检查时间
            connector.setConnectTimeoutCheckInterval(ConfigMgr.getInstance().getClientConnectTimeoutCheckInterval());
            connector.setHandler(ConfigMgr.getInstance().getClientIoHandler());
            ConnectFuture connectFuture = connector.connect(new InetSocketAddress(ip, port));
            DatagramSessionConfig dataGramSessionConfig = (DatagramSessionConfig)connector.getSessionConfig();
            dataGramSessionConfig.setBroadcast(true);
            // 等待建立连接
            connectFuture.awaitUninterruptibly();
            System.out.println("udp连接成功");
            IoSession session = connectFuture.getSession();
            WriteFuture wf = session.write(msg);
            wf.awaitUninterruptibly();
            connector.dispose(true);
