In this section:

The CDR Server Admin window allows you to configure an SBC Core accounting object that controls transferring files to an external CDR server. Its parameters identify the remote server and login details.

The SBC supports transferring call accounting files (.ACT) to the CDR server through a user-configured port. The SBC also supports using either a username/password combination or a Secure Shell (SSH) public key to authenticate with the remote CDR server. The parameter Use Ssh Key File  must be enabled to generate an SSH public key.

The generated SSH public key must be installed on the CDR server to use SSH key-based authentication from the SBC. The SSH public key must be copied to the remote CDR server file /home/<user>/.ssh/authorized_keys. If the private key is compromised, the key must be re-generated. Once the key is re-generated, the CDR server must be updated with the new key.

Note:
  • The SSH public key generated for the primary CDR server can also be used to authenticate the secondary CDR server. The SSH public key can be installed on both primary and secondary CDR servers.

  • The configured user must have access to /home/<user>/.ssh for reading the public key.

Configuring CDR Server Admin List

To view the list of CDR Server Admin objects, on the SBC main screen, go to Administration > Accounting and Logs > CDR Server > Admin. The CDR Server Admin window is displayed. You can configure a primary and a secondary object.

  • IPv4—This is V4 IP address in dotted decimal form (for example 128.127.50.224).
  • IPv6—This is V6 IP address in hexadecimal/colon form (for example, 1280:1276:3350:2224:2222:3333:8888:1245 or fd00:21:445:128::7880).
CDR PortSpecifies the SSH port number of the remote server. The value ranges from 1 to 65535 and the default value is 22.
Use Ssh Key File Enable this parameter to use SSH public key for authenticating the remote CDR server.  
  • Disable (default)
  • Enable

Username

Specifies the remote username.

Password

Specifies the remote server password.

Note: You can enter password in non-echo mode when prompted and not inline. 

Path

Specifies the remote directory path where the files should be transferred.

File Prefix
