		<description><![CDATA[This may be a surprise to some people, but I personally believe that Microsoft&#8217;s Active Directory is one of the best directory services out there. It offers LDAP, RADIUS, Kerberos, internal Certificate Authority servers, and more. Tying all of that together yourself with OpenLDAP, Samba, open source RADIUS servers, and other services would be a [...]]]></description>

This lead me to begin testing all the inbound MX records for Google domains, and domains hosted by Google Apps to see if I could reproduce this [...]]]></description>

		<description><![CDATA[Turns out, the OpenBSD CARP (failover protocol) conflicts in port number, and behavior with devices running VRRP. We have switch and router equipment which uses VRRP to perform gateway fail over. When we brought in CARP, using the same CARP VHID, and VRRp VRID will cause severe packet loss, as it seems the devices become [...]]]></description>

		<description><![CDATA[I&#8217;ve had this goal for quite some time now, every since my employer went with Sun X4540 storage systems to serve as our data storage for backup applications. The goal was to handle data replication at the ZFS file system level, removing the need for application-level awareness of the file system replication. A couple products [...]]]></description>

		<description><![CDATA[While setting up and testing our Sun X4540 OpenSolaris NFS server, I noticed that our FreeBSD NFS clients were having severe performance issues while writing to the server. After a few days of digging around, I came across some ancient posts (circa 2005) on the FreeBSD-performance mailing lists describing similar problems. Here is a brief [...]]]></description>

		<description><![CDATA[I've wondered how to integrate standard SNMP traps into Zabbix for some time, many of our systems are Dell's with OpenManage installed. OpenManage supports sending SNMP traps to a monitoring station who receives them and then takes defined actions. Inside you'll find a writeup on how to capture and report on various SNMP trap events.]]></description>
