  1. By default, the Red Hat Enterprise Linux (RHEL) profiles block all ports except for those that are listed in the following table.

  2. For SUSE Linux Enterprise Server (SLES), some open ports are dynamically assigned based on the operating system version and profiles. For a complete list of open ports, see your SUSE Linux Enterprise Server documentation.

  3. For Ubuntu Linux Server, some open ports are dynamically assigned based on the operating system version and profiles. For a complete list of open ports, see Ubuntu Server documentation.
