Preparation and Installation of the CDRouter Demo

Thank you for exploring CDRouter for your broadband gateway, CPE, and Wi-Fi access point testing needs! This page will help you get the CDRouter Demo up and running in seven easy steps. Please feel free to contact us at if you have any questions.

1. Select a Linux system

To get started, you must provide a suitable bare-metal Linux system that meets the hardware and software requirements below. Note that virtual machines are not supported.

Hardware requirements

An x86_64 (64-bit) PC with at least three (3) Ethernet interfaces is required. One interface will be used for management of the system and the other two will be used for testing. The two test interfaces will be connected to the LAN and WAN interfaces of the device under test (DUT).

Most 802.11 a/b/g/n/ac/ax Wi-Fi interfaces that are natively supported by Linux may also be used with the CDRouter Demo. Please contact for guidance on selecting an appropriate Wi-Fi interface, if needed.

Software requirements

The CDRouter Demo must be installed on a system running Rocky Linux 8. Rocky Linux 9 is not currently supported.

We recommend downloading the GNOME (Workstation) ISO image from the Rocky Linux 8 download mirror:

The ISO image should be installed on a bootable USB stick that is 4 GB or greater in size.

2. Install Rocky Linux 8

Boot from the USB stick to start the Rocky Linux 8 installation process on your PC. When the Desktop appears, the option to run the Rocky Linux installation program will be displayed:

Select Install to Hard Drive to begin the installation process.

Note that you may need to perform a few Linux administration tasks prior to and during the installation of Rocky Linux 8, such as partitioning the hard drive, choosing a password for the root user, or adding an additional user:

Once you’ve completed these tasks, press the Begin Installation button:

Note that the default installation settings will work in most situations.

Following installation, please remove the USB stick and reboot the system. The system should boot into Rocky Linux 8.

3. Post install setup

Disable firewalls

To access CDRouter’s web UI the selinux and firewalld services must be disabled on the system. Please perform the steps below from a terminal window or SSH session on the system.

a) As the root user, edit the selinux config file /etc/selinux/config and change the value of the SELINUX option from enforcing to disabled:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled                                         <--------------
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.

b) Also as the root user, disable firewalld by running the following command:

systemctl disable firewalld

Network interface configuration

The network interfaces used by the CDRouter Demo for testing must be configured properly within Linux. The following page contains additional information and instructions on how to configure the test interfaces:

Reboot the system

Once all post install steps have been completed, reboot the system to apply all changes.
