net.js UNIX domain socket issue

domainsocket.js

var net = require('net');
var path = '/tmp/echo.sock';
var server = net.createServer(function(c) {
    console.log('server connected');
      c.on('end', function() {
            console.log('server disconnected');
              });
        c.write('hello\r\n');
          c.pipe(c);
});
server.listen(path, function() {
    console.log('server bound on %s', path);
});

And now?
