Downloading Cisco Access Registrar Software

Chapter 1 Overview

Example Configuration

The installation dialog asks if you want to install the example configuration. You can use the example configuration to learn about Cisco AR and to refer to the examples that appear later in this document.

You can delete the example configuration at any time by running the command:

/opt/CSCOar/bin/aregcmd -f /opt/CSCOar/examples/cli/delete-example-configuration.rc

Base Directory

The installation process asks “where do you want to install [/opt/CSCOar]?”

If the base directory does not exist, the installation process asks if you want to create the selected base directory.

The selected base directory </opt/CSCOar> must exist before installation is attempted.

Do you want this directory created now [y,n,?,q]

The base directory must be created before you can install the software. If you do not agree to create the base directory at this point, the installation process terminates and no changes are made to the system. The default base directory is /opt/CSCOar.

setuid and setgid Permissions

The installation process asks before installing the following files with setuid and setgid permissions:

•/opt/CSCOar/.system/screen <setuid root>

•/opt/CSCOar/bin/aregcmd <setgid staff>

•/opt/CSCOar/bin/radclient <setgid staff>

If you do not agree to install these files, the installation will continue, but you will only be able to run aregcmd as user root. Cisco recommends that you answer Yes to this question.

Continue with Installation

The final question asked by the installation process dialog is, “Do you want to continue with the installation of <CSCOar>?” Enter Y or yes to continue with the installation. No further user input is required.
