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.
- 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.
