This chapter provides information about CSRC support for multiple hosts. It also provides an installation worksheet that can helfp you enter consistent values when you install the software packages required to run CSRC. This chapter also provides information to help you design your data center.
The Cisco Subscriber Registration Center (CSRC) software packages operate with the following five software components:
You must precisely install and configure each software package to ensure the proper operation of CSRC. If you already have the required version of a component installed, you do not need to re-install it.
To install CSRC and the five independent software packages that CSRC requires, you need the following:
During the installation of CSRC and the various required software packages, the installation utilities sometimes require you to enter values that pertain to the installation of a previously installed component (for example, the LDAP administrative password entered during the directory server installation). The "CSRC Installation Worksheet"
(Table 2-1) is designed to help you remember the values you enter and to provide consistent parameter information.
Before you begin installing CSRC, review the parameters listed on the "CSRC Installation Worksheet" in the Parameter column. These are the parameters for which multiple installer programs ask you to enter values. If you know a parameter value, enter it in the corresponding numbered box in the Value column.
Default values, if available, are prefilled in the dialog boxes.
As you install each required software package, refer to the appropriate box on the "CSRC Installation Worksheet" when the installer prompts you for a specific parameter value. If a value is not specified explicitly on the "CSRC Installation Worksheet", then enter that value at the installer's prompt and in the appropriate box on the "CSRC Installation Worksheet" to help you remember it.
 | Tips
Make a photocopy of the "CSRC Installation Worksheet" and enter the parameter values on the photocopy.

The architecture of CSRC provides for flexibility in designing your data center. CSRC requires that you install the following software packages:
You can install the software packages on multiple hosts with different operating systems. If you choose to install multiple CSRC packages on the same host and these packages both require the same additional support package, you only need to install the additional package once on the host. For example, both the CNR user interface and the Web user interface packages require Perl. If you install the CNR user interface and the Web user interface on the same host, you only need to install Perl once on the host.
Table 2-2 lists the major server components of CSRC and the software components that you must install for each server component.
| Server Component | Required Software |
|---|---|
Directory Server | Directory Server LDAP data Perl |
Cisco Network Registrar Server (CSRC DNS services) | Cisco Network Registrar |
Cisco Network Registrar Server (Standard DNS) | Cisco Network Registrar |
Cisco Network Registrar Server (DHCP services) | Cisco Network Registrar |
Cisco Network Registrar Server (Time of Day and TFTP services) | Cisco Network Registrar CNR user interface Perl |
CSRC Web Interface (Modem Registrar and User Registrar) | Web user interface Netscape Application Server Web server CNR user interface Perl |
CSRC Command Line Utilities | Utilities CNR user interface Perl |
Table 2-3 lists the major components of CSRC and provides three example configurations.
| Server Function | Example 1: Four Hosts | Example 2: Five Hosts | Example 3: One Host |
|---|---|---|---|
| Directory Server
Provides directory services. | Host 1 | Host 1 | Host 1 |
| Cisco Network Registrar Server (CSRC DNS services)
Provides DNS services for the User Registrar component of CSRC. Provides a "dummy" root zone that resolves all names to the CSRC User Registrar server. | Host 2 | Host 2 | Host 1 |
| Standard DNS Services
A place holder for "standard" DNS services, which are not part of the CSRC installation. If you use CNR to provide DNS, Cisco recommends a three-server configuration in the RDC: two primary servers (forward and reverse) and one secondary server that accepts resolver requests. | |||
| Cisco Network Registrar Server (DHCP services) | Host 3 | Host 2 | Host 1 |
| Cisco Network Registrar Server (TOD and TFTP services)
CNR time-of-day (TOD) and trivial file transfer protocol (TFTP) servers typically share a single host. | Host 3 | Host 3 | Host 1 |
| CSRC Web user interface
Provides the core CSRC services, such as User Registrar. You must install the software components required for this server on one host. | Host 2 | Host 4 | Host 1 |
| CSRC command line utilities
Cisco recommends that you install these utilities on the same host as the CSRC Web user interface. | Host 2 | Host 4 | Host 1 |
| Cisco Access Registrar (CAR) RADIUS Server
Required for installations in a telco-return cable modem environment. You cannot install CAR on the same host as CNR. This guide does not discuss the installation and use of CAR. | Host 4 | Host 5 | Not Applicable |
The process used to install CSRC involves installing five independent software components as well as the CSRC software packages. Since CSRC is not a standalone, off-the-shelf product, but instead depends heavily on the proper installation and configuration of other applications and utilities, Cisco recommends that you first review the installation process summary to familiarize yourself with the overall installation process.
For more detailed information, see the appropriate chapters in this guide.
Step 1 Install Perl from the CSRC distribution media or download Perl version 5.00503 or higher from the Internet.
Step 2 Install Cisco Network Registrar version 3.0 (1)T or higher Technology version.
Step 3 Install a Web server if one is not already installed.
Step 4 Install an LDAP version 3 compliant directory server.
Step 5 Install the Netscape Application Server version 2.1 for Windows NT.
Step 6 Install the CSRC software packages for Windows NT.
Step 7 Verify the installation.
Step 8 Change encoded CSRC passwords.
