Enable firewalld in Centos 7 How to do it

This article will guide you on steps to enable firewalld on #centos 7 servers for our customers. The firewall is one of the most important features of webservers. The #firewalld supports both IPv4 and IPv6 #firewall #settings.

Never run the iptables service and FirewallD service at the same time! The #iptables service is now provided by a separate package called iptables-services: Stop and disable the firewalld service first. # systemctl stop firewalld.

The firewalld daemon manages groups of #rules using entities called "zones". Zones are basically sets of rules dictating what traffic should be allowed depending on the level of trust you have in the networks your #computer is connected to.

To use FirewallD:

1. Installing and Managing FirewallD.

2. To start the service and enable FirewallD on boot: sudo systemctl start firewalld sudo systemctl enable firewalld.

3. Check the firewall status.

4. To view the status of the FirewallD daemon: sudo systemctl status firewalld.

5. To reload a FirewallD configuration: sudo firewall-cmd --reload.

If you apply draggable() to the modal dialog element, the browser window scroll bars will drag around the screen as you drag the modal dialog. The way to fix that is to apply draggable() to the modal-dialog class instead: $(". modal-dialog").
