Trying to setup a node.js web server

Question

I am new to web servers and node.js and I need some help.

I have no idea what to put in the .listen();

I think since I want it to connect to the internet the server needs to listen to port 80 but but I don't know what to put as the second value.

.listen(80, "What do I add here?");

Also i have a free domain name (www.example.co.cc) that is pointing to a dynamic dns (DnsExit) since I dynamic ip. I installed to program needed to update my ip address.

Is there anything I am missing?

Have you seen the example on the homepage of the Node.js project?

http://nodejs.org/

It clearly demonstrated .listen( 1337, "127.0.0.1" ); and then the next line reads Server running at http://127.0.0.1:1337/ - so the second argument is the IP you want to listen on. If you then take a look at the documentation you will see that this second argument is actually optional, if you omit it, Node.js will accept incoming connections directed at any IPv4 address.

http://nodejs.org/docs/v0.5.6/api/http.html#server.listen

How are you testing the connection via your domain? Because, usually you cannot connect to your own IP address (if you are behind NAT, which most people are). So if your external IP is 1.2.3.4, and your domain is pointing to 1.2.3.4, going to your own domain won't work. Try your domain on this: web-sniffer.net

I have already forwarded port 80 and on web-sniffer.net it gets the right ip address and port 80 but it fails to connect. here is what web-sniffer said: Connect to (My ip) on port 80 ... failed Error 110: Connection timed out Error while fetching URL

If it's working from localhost, then my guesses would be either it's only listening to local (you could try second argument 0.0.0.0, but according to the documentation it already uses something similar internally if you omit it.) or there is something wrong with your port forwarding / firewall settings.
