Talking about updates and the updates manager, this screenshot shows the type of interface that the updates manager presents, if there are any updates. By the way, the list of applications shown in this image, are the available updates after booting into a new installation on one of my test systems.

Aside from Synaptic, there is an alternate package manager in the System Control Center. It too, like Synaptic, looks old, but it works.

Graphical Administrative Applications: Graphical applications for managing desktop settings are accessible from the KDE Settings manager. For system-wide management tasks, there are several applications in the System Management Center. Like Synaptic, they work, but they all have a very old feel to them. This screenshot is a view of the main interface of the System Management Center.

Physical and Network Security: With no support for disk encryption and boot loader password protection, ALT Linux 6 KDesktop has a very weak physical security posture. Throw in the fact that the screensaver and its security setting, are deactivated by default, the physical security posture slips even lower.

On the network security front, things are no better. Even with ports 13 (daytime), 22 (ssh), and Samba ports (139 and 445) open out of the box, the firewall is not enabled. There is a graphical firewall application, but it too, of course, is disabled out of the box. The image below shows the graphical firewall in its default state.

Aside from the firewall, there is an Internet Protocol address blacklisting application in the System Management Center that you may use to blacklist offending IP addresses. Other than the firewall and this blacklisting application, I did not see any other network security system in place.

Final Thoughts: The most striking aspect of ALT Linux 6 KDesktop is that even though it is running a very recent version of the K Desktop Environment, it has a very old feel. It is not something I can explain, but that should not take any thing from the fact that it is a very stable distribution, one that I would not hesitate to recommend to any person looking to distro-hop.
