    Well, nobody want to use Webmin without SSL. So just add the correct stuff, if not already installed:
    # yum install openssl
    # yum install openssl-devel
    # yum install perl
    # yum install perl-Net-SSLeay perl-Crypt-SSLeay

  3. Shorty Stuff says:

    Does Webmin support the new firewalld in RedHat/CentOS 7, or is it stuck with the old iptables?

    • vlad says:

      there is a new plugin “FirewallD” that you need to install fro mthe webmin modules to support that.

    You should use this command to add the firewall rule:

      Are you definitely using centos 7?

    • Radek Havelka says:

      well the correct command is firewall-cmd –add-port=10000/tcp –permanent, with TWO dashes before ADD and PERMANENT …

      • Radek Havelka says:

        and because this idiotic comment system replaces it, this is with added spaces …

        firewall-cmd – -add-port=10000/tcp – -permanent

    Maybe the firewall is not installed:
    1. Check the status with systemctl status firewalld
    2. Install firewall if need it with yum install firewalld
    3. Reboot a try again to add the port
