Basic setup of Fedora 20 firewall |
2014-04-11 |
Linux Fedora |
After almost a decade of using Centos and Red Hat, jumping into Fedora 20 can be quite a learning experience, let's take one step at a time.
To start with, firewall administration is now administered through zones which are administered with the firewall-cmd . In order to start making use of anything with a Linux command line utility, one must start by knowing the state of things:
{% highlight bash %} $ firewall-cmd --state $ firewall-cmd --list-all-zones $ firewall-cmd --zone=public --list-ports {% endhighlight %}
If you don't have the necessary ports open, they can be opened up explicitly:
{% highlight bash %} $ firewall-cmd --zone=public --permanent --add-port=80/tcp $ firewall-cmd --zone=public --permanent --add-port=22/tcp {% endhighlight %}
or you can use the pre-defined zones:
{% highlight bash %} $ firewall-cmd --add-service=http --permanent {% endhighlight %}
