Review the ports that the Controller uses to communicate with agents and the rest of the Splunk AppDynamics On-Premises platform. For more information, see Port Settings.

Note that on Linux systems, port numbers below 1024 may be considered privileged ports that require root access to open. The default Controller listen ports are not configured for numbers under 1024, but if you intend to set them to a number below 1024 (such as 80 for the primary HTTP port), you need to run the Enterprise Console as the root user.
