We are facing one weird problem on one of our RHEL apache server.Actually, it is not listening on port 80 from remote hosts. When we locally browse http://localhost it is opening default page. When we checked listening port through netstat, we found that only tcp6 interface was listening at :::80.And there was no entry for tcp, and that entry should be present there liketcp 0 0 0.0.0.0:22 0.0.0.0:* LISTENI have tried searching many forums for this issue, but none of the solution suggested worked. In httpd.conf, we change Listen 80 to Listen 0.0.0.0:80and Listen 127.0.0.0:80but it did not open 80 port to access from remote hosts. IPtables is disabled from the beginning.How can we set the server to listen on IPv4?
Apache server not listening on IPv4 but listening on IPv6
iptables;apache httpd;port forwarding;ipv6;ipv4
