Dell DL4000 Appliance Deployment Guide

Configuring the Rapid Recovery Agent on a Linux machine

1. Open a terminal session with root access.
2. Launch the configuration utility by typing the following command, and then press Enter:

   		sudo /usr/bin/rapidrecovery-config

   The configuration utility starts. This lists several configuration options, each with an index number to enter for the appropriate configuration step.

3. Configure the port for this protected machine by typing the following command, and then press Enter. The default port is 8006.

   		1 <agent_port>

   For example, if using the default port, type the command:

   		1 8006

4. Configure users available for protection, by typing the following command, and then press Enter:

   		1 <user_names_separated_by_comma>

   For example, if using usernames michael, administrator, and test_user1, type the command:

   		2 michael,administrator,test_user1

5. Configure firewall rules to select a firewall configuration manager. This establishes firewall exceptions for the port designated in step 1.

   If the utility detects one or more firewall configuration managers (such as lokkit or firewalld), each is listed in the utility in line 3. Select the appropriate configuration manager and enter it, starting with the command number (3), and then press Enter:

   		3 <firewall_configuration>

   For example, if using firewalld, type the command:

   		3 firewalld

6. Query the list of compatible kernel modules from the utility by entering the command number, and then press Enter:

   		4

   A sub-shell returns all kernel modules compatible for installation. For example, the following could be returned:

   Searching for all available for installation kernels.
   This might take a while, depending on the Internet connection speed.
   Kernels compatible for module installation:
    0 - linux-image-3.16.0.23-generic
    1 - linux-image-3.16.0.31-generic
    2 - linux-image-3.16.0.33-generic
    3 - linux-image-3.16.0.34-generic
   Input indices of the kernel modules you wish to install, delimited by space; use 'all' to install into all supported kernels, or 'q' to quit.

7. Configure the appropriate Rapid Recovery kernel module.

   For example, to enter kernel modules for 3.16.0-23 and 3.16.0-34, enter 1 4 and press Enter.

   To enter all kernel modules, enter all and press Enter.

8. After configuring the newly installed Agent software, restart the machine. Restarting ensures that the proper kernel driver version is used to protect your machine.
