I'm just starting out in Ubuntu/Linux, and have some trouble opening port 80 for incoming connections.

I ran the sudo ufw allow 80/tcp command, and when I run sudo ufw status the result looks like this:

Status: active



To                         Action      From

--                         ------      ----

22                         ALLOW       Anywhere

80/tcp                     ALLOW       Anywhere

22 (v6)                    ALLOW       Anywhere (v6)

80/tcp (v6)                ALLOW       Anywhere (v6)

However, I still get this error when trying to connect to the port with cURL.

Failed to connect to MY_IP_ADDRESS port 80: Connection refused

When I run this command netstat -ntlp | grep LISTEN to see what ports are open, I get this result:

(No info could be read for "-p": geteuid()=1000 but you should be root.)

tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      -               

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -               

tcp6       0      0 :::22                   :::*                    LISTEN      -         

Which doesn't look that promising..

How do I open port 80 for incoming connections?
