No httpd service listening on TCP4

[74cmonty]

Hi,
I just completed installation with Fedora 29 in KVM.
The installation finished w/o errors.
Setup complete

Next steps:
        1. You must make sure these network ports are open:
                TCP Ports:
                  * 80, 443: HTTP/HTTPS
                  * 389, 636: LDAP/LDAPS
                  * 88, 464: kerberos
                  * 53: bind
                UDP Ports:
                  * 88, 464: kerberos
                  * 53: bind
                  * 123: ntp

Checking the open ports I cannot identify any TCP4 port 80,443.
[root@ipa ~]# netstat -tulpen | egrep "80|443"
tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      17        
56422      3678/java
tcp6       0      0 127.0.0.1:8009          :::*                    LISTEN      17        
53206      3678/java
tcp6       0      0 :::80                   :::*                    LISTEN      0         
60216      4570/httpd
tcp6       0      0 :::8080                 :::*                    LISTEN      17        
53200      3678/java
tcp6       0      0 :::443                  :::*                    LISTEN      0         
60224      4570/httpd
tcp6       0      0 :::8443                 :::*                    LISTEN      17        
53204      3678/java

Ports 80,443 are listening on TCP6 only.

How does this happen?

That is normal, they are actually listening on both IPv4 and IPv6. The netstat output
shows it as :::80 :::*. Listening on both protocol versions makes it show up as IPv6. You
do not get two separate entries.
You could try to start netcat in listen mode on port 80 and you’ll find that it errors out
because the port is in use.

Regarding the post-setup network access in general; you’ll need to fix your firewall to
allow access; by default it is blocked. See firewall-cmd for more info (IIRC).
