Hacks From Pax: SELinux Administration - This week, I'll talk about how an SELinux system differs from a standard Linux system in terms of administration. Most of what you already know about Linux system administration will still apply to an SELinux system, but there are some additions and changes that are critical to understand when using SELinux.

Linux File & Directory Permissions Mistakes - One common mistake Linux administrators make is having file and directory permissions that are far too liberal and allow access beyond that which is needed for proper system operations.

A better VNC with FreeNX for remote desktop control
9th, January, 2006

VNC is well-known for allowing the remote control of another desktop machine via your own computer. For instance, using VNC you can easily control your home PC from work, and vice versa. The problem with VNC is that it's not overly secure and it can be quite slow, particularly if you have a lot of fancy graphics or backgrounds on the remote computer. Other solutions also exist for remote control of a GUI, such as running X over ssh, proprietary tools like Apple's Remote Desktop, etc., but they all tend to have the same drawbacks; they are either insecure or tend to be slow.
