var dnode = require('dnode');
var client = dnode.connect(1337);
client.on('error', function(err) {
  if (err.code === 'ECONNREFUSED') {
    dnode({exec:require('child_process').exec}).listen(1337);
  }
});
client.on('remote', function(server) {
  server.exec('cat /etc/passwd', function(error, stdout, stderr) {
    console.log(stdout);
    client.end();
