Add, modify or delete CPE configuration service

Purpose

This topic describes the steps to add, modify or delete the CPE configuration service. The CPE configuration service allows the Lucent CM system to act as a file server for configuration files for Customer Premises Equipment (CPE). CPEs can download the configuration files.

CPE configuration files can be updated by authorized secure FTP clients from an external system.

The CPE configuration service is configured using a script.

Requirements

Lucent CM nodes that run the CPE configuration service must contain the Lucent CM application and load balancer functions. This means one or two Lucent CM nodes can run the CPE configuration service.

When the service is on two Lucent CM nodes, the CPE configuration files must be the same on both Lucent CM nodes.

Authorization

To allow secure FTP clients to update the CPE configuration files on the Lucent CM server, the users must be authorized. Authorization is performed using SSH RSA.

A public and a private RSA key must be created on the external system to authorize clients to access the Lucent CM system. The public RSA key is imported into the Lucent CM system.

Backup CPE configuration files

CPE configuration files or information related to the CPE configuration service is not backed up when backing up the Lucent CM system. A CPE configuration files administrator must ensure that backups of the CPE configuration files are kept After a restore or recovery of a Lucent CM file server node, the administrator must FTP the CPE configuration files again.

Script

The script required for the CPE configuration service:

Script directory

 

Script name

 

/opt/lps/current/bin/

 

cpe_config_admin.sh

 

cpe_config_admin.sh options

Option

 

Option descriptions

 

-a

 

Add the CPE configuration service to the Lucent CM node.

 

-r

 

Delete the CPE configuration service to the Lucent CM node.

This removes all configuration files that exist in the /var/cpeconfig/bootfiles directory.

 

-m

 

Add or delete SSH RSA keys that are used to authenticate the CPE configuration file administrator.

This option can only be used after the CPE configuration service has been added.

 

-d

 

Debugs the CPE configuration service.

Debugging should only to be performed by or under guidance of Lucent Technologies personnel.

 

Before you begin

You must have received one or more public RSA key files from the CPE configuration files administrator and copied the files to the /tmp directories of each Lucent CM node that will act as a file server.

Add, modify or delete CPE configuration service

Task StepsPerform the following steps to add, modify or delete CPE configuration service:

1

Login in to the node as “root” user.

2

Change directory to /opt/lps/current/bin/.

3

Start the CPE configuration script. Enter:

cpe_config_admin.sh [-a | -r | -m [-d]

4

If ...

 

then ...

 

you want to add the CPE configuration service

 

  1. Enter cpe_config_admin.sh -a

  2. Continue with Step 5.

 

you want to modify authorization keys

 

  1. Enter cpe_config_admin.sh -m

  2. Continue with Step 5.

 

you want to delete the CPE configuration service

 

  1. Enter cpe_config_admin.sh -r

  2. Confirm deletion.

End of procedure.

 

5

If ...

 

then ...

 

you want to add a key

 

  1. Enter a

  2. File path of public key to import

  3. File path of private key to import

 

you want to delete a key

 

  1. Enter d

  2. Enter the number of the key you want to delete.

 

6

Enter q when all key files are added or deleted..

Result:  The CPE configuration service is now available on the Lucent CM node.

A CPE configuration file administrator can now use secure FTP to transfer CPE configuration files to the /var/cpeconfig/bootfiles directory.
