Node.js: ECONNREFUSED on Port 80

Question

I've written a web-server using Node.js. When I tried to test my server with the tester I've written for it, I succeed only if the port I'm using for the server is not 80. I've checked on netstat, and no other application is using port 80. The error I'm getting on the console is:

Error: connect ECONNREFUSED
  at errnoException (net.js:640:11)
  at Object.afterConnect [as oncomplete] (net.js:631:18)

What can be done in this case?

Answer 1

You should not make a habit of running node as a privileged user. Here is a method I'm using on 6 different machines:

Use iptables to forward incoming traffic on port 80 to 8080 like so:

sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

Then be sure to save that

sudo iptables-save

Youd also want to add that to rc.local so those are set at reboot or instance launch (in the case of EC2 or other cloud)

Then you can safely start node listening on 8080 as any user.
