		<title>A Practical View of Comcast vs FCC</title>
		<description><![CDATA[One thing to note about the United States Court of Appeals for the District of Columbia Circuit  decision in Comcast vs. F.C.C.&#8211; it doesn&#8217;t restrict the F.C.C.&#8217;s ability to regulate Internet services; rather, the court ruled that the broad regulatory powers  enjoyed by the F.C.C. were overstepped when they told Comcast  to [...]]]></description>

		<title>Automount USB drives on Ubuntu servers.</title>
		<description><![CDATA[In most cases, Ubuntu desktop systems will automatically detect and mount removable media, and this is largely done with software that is part of the X Windows system; for server systems without X Windows however, this sort of thing requires a bit of work.
Now some may ask, &#8220;Why automount removable media at all?&#8221; It is [...]]]></description>

		<title>Diagnosing Sound Problems in Ubuntu Linux</title>
		<description><![CDATA[Sound problems fall in to three basic categories, and the first thing you want to do is determine which one you&#8217;re dealing with.

		<title>SSH Coolness &#8230; even on Windows.</title>
		<description><![CDATA[prerequisite concepts: prelude, basic config., port fwd, proxy conn.

I don&#8217;t often have the opportunity to experiment on computers running Windows, but every  once in a long while it simply cannot be avoided. I recently found myself wanting to look up a password in Revelation, a password manager for the Gnome Desktop on Linux; I [...]]]></description>

		<title>OpenSSH: Environmental Override</title>
		<description><![CDATA[prerequisite concepts: prelude, basic configuration
This post is as much about customizing the root shell as it is about SSH environment variables, but I&#8217;m adding this to my OpenSSH collection because it&#8217;s applicable to  any user.
I occasionally work on servers where, for a variety of reasons, I share an account with one or more other [...]]]></description>

		<title>OpenSSH: Proxy Connections</title>
		<description><![CDATA[prerequisite concepts: prelude, basic configuration, port forwarding
Network address translation (NAT) is a very common method of providing secure access to hosts on a private network.  Given the limited amount of IPv4 addresses, computer networks with relatively few, very few, and even a single public IP address are common. A typical small business customer of [...]]]></description>

		<title>I have seen the light.</title>
		<description><![CDATA[Having discovered the advantages of á la carte VoIP pricing, I pondered how to extrapolate my experience for general discussion while avoiding the pitfalls of interpolation and abridgement.

		<title>OpenSSH: Basic Configuration</title>
		<description><![CDATA[prerequisite concepts: prelude
If you&#8217;re not already using a config file (~/.ssh/config) you should peruse the documentation to see what it offers; an ongoing benefit I enjoy is that it allows me to accomplish more while typing less.
