		<description><![CDATA[I haven&#8217;t really spent that much time configuring nscd, so I thought I would take a crack at it this morning while sipping my cup of joe. Looking at one of my production hosts, I queried for the &#8220;host&#8221; cache statistics. This is the nscd cache which keeps DNS lookups. With the nscd daemon running, [...]]]></description>

		<description><![CDATA[I have been replacing some old hardware over the past few months, and recently noticed that we had several machines with uptimes in the hundreds of days (one 800+ days). For the longest time I thought only Solaris and AIX provided this kind of stability, but over the past few years I&#8217;ve started to include [...]]]></description>

		<description><![CDATA[One feature I really liked in Solaris 10 was SMF.  It provides a framework using services manifests on the system to automatically respawn services should they die off.  It handles dependencies, restarts, and a single unified command set to configure the system using svcs, svccfg, and svcadm.
