What port does the Agent use to connect to the Server?

The Agent communicates with the Server using https protocol (port 443). If your organization blocks access to the Internet, contact your Network administrator to grant outgoing access to the following:

  • *.controlm.com:443 (https protocol) (outgoing only)

  • *.amazonaws.com:443 (outgoing only)

What is the difference between root mode, non-root mode, and sudo mode?

The Agent works in one of the following modes:

  • Root Mode: Enables the Agent to execute all submitted jobs without the need for the Run as user password.
  • Non-Root Mode: Enables the Agent processes to run with the Agent account permissions. To run a job with a different Run as User, you need to define the Run as User authentication settings, as described in Adding a Run as User .

  • Sudo Mode: Enables the Agent processes to run with the Agent account permissions. To run a job with a different Run as User, you need to define the Run as User in the operation system sudoers file. See Agent modes for more information.

    BMC recommends using non-root mode.
How do I change the default Agent mode? To set the Agent mode, you need to log in as root and run the set_agent_mode script, as described in Running the set_agent_mode Utility.
