Solution 2112055.1 : CDR/HDR push failing to SFTP server.

Applies to:

Acme Packet 4500 - Version S-Cz7.2.0 to S-Cz7.3.0 [Release S-Cz7.0]
Acme Packet OS

Symptoms

CDR/HDR push failing from SBC to SFTP server.

Changes

Customer replaced the old SFTP server with the new SFTP server.

Cause

Since customer was using plain username and password, asked customer to import the host-key of SFTP server to SBC.

Solution

Following steps were followed to find the resolution :-

1) Check whether its a new installation or a working setup. If it was a working setup, was there any change such as ip-address, username, password or a new server was installed.

2) Does manual SFTP/SSH to the remote sftp server works fine? Since SBC doesn't support SFTP/SSH please request customer to do a SFTP from a local machine to the SFTP server.

3) Please verify the directory path of SFTP and configuration in SBC. Make sure that the directory has write permissions and enough space in the SFTP server.

4) If customers are using public key for authentication, then check the certificate validity, and import both RSA and DSA keys.

5) If plain username and password is used then verify manual login works fine.

6) If no public key is used and plan username, password is used then please follow the below steps and import the host key of SFTP to SBC for the CDR/HDR push to work :-

(i) On Sftp Server:

[root@JSSIndia-155 ssh]# ssh-keygen -e -f /etc/ssh/ssh_host_dsa_key.pub | tee sftp_host_dsa_key.pub
