Permanently Changing the Port a CIM Extension Uses (UNIX Only)

CIM extensions on UNIX use port 4673 by default. You can start a CIM extension on another port by entering ./start -port 1234, where 1234 is the new port. With this method, you must always remember to provide the nondefault port when starting the CIM extension.

You can configure a CIM extension to remember the nondefault port, so you only need to enter

./start to start the CIM extension:

1.Go to the /opt/APPQcime/conf directory.

2.Open the cim.extension.parameters file in a text editor, and provide the following line:

-credentials username:password

-port 1234

IMPORTANT: The values for -credentialsand –portmust be on separate lines, as shown in the example.

where

•username is the user that is used to discover the CIM extension. You will need to provide this user name and its password when you discover the host.

•password is the password of username.

•1234 is the new port for the CIM extension

3.Save the file.

4.Restart the CIM extension for your changes to take effect.

NOTE: The CIM extension looks for parameters in the cim.extension.parameters file whenever it starts, such as when it is started manually or when the host is rebooted.

5.The management server assumes the CIM extension is running on port 4673. If you change the port number, you must make the management server aware of the new port number.

Enter the port number on the System Protocol Settings page (Options > Protocol Settings > System Protocol Settings) under the WBEM section. See the SIM documentation for more information.

Configuring UNIX CIM Extensions to Run Behind Firewalls

In some instances you will need to discover a host behind a firewall. Use the following table as a guideline. Assume the management server wants to discover HostA, which has three network interface cards on three separate networks with three separate IPs: 10.250.250.10, 172.31.250.10, and 192.168.250.10. In the following table different configurations are presented:

•The “Manual Start Parameters for CIM Extensions” column provides what you would enter to start the CIM extension manually on the host. See the Installation Guide for more information on how to start a CIM extension manually.
