As a prerequisite, you must purchase a license key from your CTERA authorized reseller, specifying your portal's DNS suffix, antivirus requirements, and the number of required CTERA Edge Filers, server agents, and workstation agent licenses. You receive one or more license keys.
You can view your CTERA Portal's DNS suffix, in the global administration view's Settings > Control Panel > Global Settings page. This DNS suffix was set up when you installed the CTERA Portal, as described in the installation guide for your environment.
To extend a trial license requires Internet access. If this is a problem, contact CTERA support.
