NodeJS on Remote Ubuntu 14.04 not working

Question

I have a remote server running on Ubuntu 14.04. I have used express-generator to create a basic express APP.

The nodeJS is listening on port 8000. When I make a request using the http://ServerIP:8000 there is no response. The HTTP request is actually going through but does not seem to reach the nodejs process.

sudo tcpdump -vv -x -X -s 1500 -i interface1 'port 8000'

xx.xx.xx.xx > yy.yy.yy.yy.8000: Flags [S], cksum 0x18b7 (correct), seq 202090794, win 65535, options [mss 1400,sackOK,eol], length 0

Also

netstat -pan | grep 8000
tcp        0      0 0.0.0.0:8000            0.0.0.0:*               LISTEN      2769/node

Any idea whats going wrong/what I'm missing ?

Answer 1

In your app.js try to define your addresss and your port

    var server = app.listen(8000, function () {
    var host = server.address().address;
    var port = server.address().port; // put your adress here :)

    console.log('Example app listening at http://%s:%s', host, port);
    });

Tell me if it works :)

Answer 2

I got the problem solved using nginx as a reverse proxy and redirect traffic to the nodejs server. I'm not really sure what the problem still is.

PS : Should I close the question ?? Or should I wait for an explanation ?
