How to fetch the CSR generated on Data Domain Management Center

Hello,

In my corporation we have strict rules about https, and attempt to browse services protected by unrecognized or untrusted source is prevented

Through the CLI, we managed to create a certificate signing request

but we didn't find any guideline on how to fetch this request and feed it to our PKI.

Since the appliance is a stripped down version of DDOS, nfs export or cifs share are unavailable.

We've tried FTP, FTPS, SCP , but all those  protocol are failing to fetch the text file located at :

/ddvar/certificates/CertificateSigningRequest.csr

so to resume we are looking for ways:

1. To fetch that file
2. Sign the request with our PKI
3. Copy the answer back to the appliance
4. Finish the  signing request workflow, and configure the https service with the signed version
5. Deactivate http and keep only the secure version
