On network security, Firewalld was supposed to be the new firewall application for Fedora, but it still not yet production-ready. Though another blogger reported that it is installed, Firewalld and Firewall-applet are not installed by default. Even when you do manager to install, firewall-applet is not even usable, so it does not really make sense to install it.
So for managing the firewall in Fedora 17, system-config-firewall is still the installed graphical interface. Out of the box, it is configured to allow connections from all sources to ssh service, a service provided by OpenSSH server. And that is a major drawback of system-config-firewall: creating more granular rules is not a simple point-and-click operation. That requires knowing how to write firewall rules in Linux.
Fedora 17 gives you all the tools with which to build a very usable Linux desktop or server. The problem, for inexperienced users, is that some of the most important after-installation tasks have to be done from the command line. An example is adding extra repositories. It would be much better to have the ability to add repositories in Apper, just as it is on the graphical package manager on Mandriva, ROSA and Mageia.
