Configuring the firewall

If the server on which Micro Focus Enterprise Developer UNIX Components is installed is running a firewall, you must ensure that certain ports and services are allowed through so that Eclipse running on a client machine can communicate with it.

To ensure successful communication between the IDE and Micro Focus Enterprise Developer UNIX Components when a firewall is active, use the configrdo utility after initial setup or if you experience problems establishing a connection between the two.

Tip: If you run the client-side and/or server-side connection diagnosis tools, these include a number of tests relating to firewall configuration, and can indicate any problems with the current firewall settings.

Use configrdo to configure the following settings:

Set the default RDO daemon and server ports used by Micro Focus Enterprise Developer UNIX Components.
Open additional ports in the firewall.
This option is only available on the following platforms: Red Hat 7.2 and later, or CentOS 7.2 and later.
Add the ssh and samba services to the firewall.
This option is only available on the following platforms: Red Hat 7.2 and later, or CentOS 7.2 and later.

These changes can be temporary (for the duration of the current firewall being active), or be made permanent (so that they persist after a system reboot). If you are not running any of the supported platforms listed above, use your operating system's firewall commands to perform the equivalent functions.
