Alfresco is an enterprise document management system. There is a free Community Edition that is open source, but its web interface pulls in an image from their official website that can be used to remotely track usage. This tracking image is added via Javascript and cannot be removed by simply changing a template. It is hard coded into a core class. This tutorial goes through the steps needed to patch the Alfresco WAR file in order to remove the tracking image. It has been tested for Alfresco 4.2c and may need to be adjusted for other versions.

Typically, internal DNS entries for websites must be different than the external addresses due to NAT issues. If your organization has a lot of web sites that exist on either a single server or a set of identical servers behind a load balancer, it’s best practice to have all DNS entries be CNAME records to either that particular server’s DNS entry or the entry for a server farm’s load balancer. Recently I was involved in a mass server migration where actual IPs were used throughout a Windows DNS server. The following is a Power Shell script designed to rename DNS records in mass on an Active Directory Domain Controller.

Using public/private key pairs to digitally sign text is a common way to validate the authenticity of a piece of data.
