CDR Server Remote Port Configuration

Spacevars
0product
is enhanced to support transferring the call accounting files (.ACT) to the CDR server through a user configured port.
Spacevars
0product
also supports using the Secure Shell (SSH) public keys instead of password to authenticate with the remote CDR server.

The following parameters are added in CDR server configuration to set remote port and ssh key based authentication:

  • cdrPort
  • useSshKeyFile 
  • generateSshPublicKeys
Note

User can either use the existing username/password or the SSH public key to authenticate with the remote CDR server. The parameter useSshKeyFile must be enabled to generate the SSH public key.

To generate a new SSH public key, execute the following command:

Code Block
languagenone
% request oam accounting cdrServer admin primary generateSshPublicKeys

The generated SSH public key must be installed on CDR server to use ssh key based authentication from 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.
