Aside from the ports and services listed on the main window, additional ports from a list of more than 60,000+ tcp and udp ports may be added from the Other Ports window. Like the ssh service, any port you add and enable from here will be accessible to all hosts and networks.
You can add custom rules from the Custom Rules window. However, adding custom rules requires loading the rule(s) from a file, which in turn requires that you know how to write IPTables rules.
New to Fedora 15 is FirewallD, a firewall daemon with a D-Bus interface, which is being designed to provide a dynamic frontend to the firewall application, so that reloading is not required when a change is made to the firewall rules. It is not installed by default, but if you do, you also need to install its applet. With the applet installed, you can make changes to the firewall from the panel, without needing to launch another application. And if it lives up to its billing, you will not need to reload or apply changes when a new rule or service is added.
If you look closely at the image below, you will see a “Panic Mode” checkbox. I could not determine exactly what enabling that mode is supposed to accomplish, but the applet crashed every time I clicked on the checkbox. I could not find any reference to a “Panic Mode” in FirewallD’s official page.
FirewallD has a very user-friendly command line utility called by firewall-cmd. For example, to enable access to the Secure Shell server, all you need to type is, firewall-cmd –enable –service=ssh. And to enable the same service for, say, 30 seconds, you would type firewall-cmd –enable –service=ssh –timeout=30.
FirewallD is expected to be the default on Fedora 16 onwards. You may read more about it here.
Another new security feature in Fedora 15 is the removal of setuid applications. These are applications that run with the permissions or privileges of the applications owner or group. Potentially, they can be a security nightmare. More about this feature here.
Final Thoughts: I think Fedora 15 is a decent distribution. Because of the projects philosophical stance on Free Software, there are certain features that are not expected to work out of the box. However, there are other features that have nothing to do with that philosophical stance that did not work as expected. I am referring, of course, to the state of Amarok, the default music player, but also to printer configuration. On many of the top distributions, a connected printer is automatically configured, but not so on Fedora 15 KDE and the other Fedora 15 Spins that I have reviewed. I am yet to review Fedora 15, the main Fedora 15 version, but judging from how a connected printer is configured on Fedora 14, I do not think it will be anything like the situation on these Spins.
These are the features that separate the good from the not-so good distributions, so I expect, hope, that when Fedora 16 rolls outs, features that should work out of the box, like automatic printer configuration, will work. And something has to be done about Amarok.
