How to open port 80 for node server on local machine?

How can I use the port 80 on my local Linux machine as the port of my node server?

The netstat command netstat -ptuln says the following about this port, while the node server is running:

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0  *               LISTEN      -                  

I found on this site some recommendations for the command sudo iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT. I executed this command but when I make a request with curl (curl it keeps responding with curl: (7) Failed to connect to xxxxxx port 80: Connection refused.

But using curl the following ways works: curl or curl localhost:80.

My conclusion is, that I somehow have not opened the port correctly, but all I could find on the internet repetitively is the command I mentioned earlier.

I am aware of the fact that I could fix this easily by using an apache server, but I would like to make it without it.

Thank you!



Paste the output from

netstat -ptuln

command.I think the problem is that your web server runs on local address and can not be reachable for other machines in network.
