    });

    ipc.server.on('MONITOR:MSG', function(msg, socket) {
        console.log(msg.data.line);
        socket.destroy();
        ipc.server.stop();
    });

    ipc.server.on('KLYNG:MSG', function(msg, socket) {
        console.log(msg.data);
        socket.destroy();
        ipc.server.stop();
    });
