[cisco-voip] [External] Re: expressway E GoDaddy certificate

[Matthew Huff]

TAC is the one that showed me. The big clue is that in expressway it has the ability to upload a private key. Why have that feature if you can't extract it?

Curious if you passed this method by Cisco/Expressway support. 

I find the Expressway support team very critical of any changes to supported methods. It's the only team that doesn't support ESXi maintenance releases unless it's explicitly stated in the document.

Same.

We have a multi-san certificate for our expressway-e cluster from Entrust. You have to create the CSR on the first node in the cluster, install the certificate and then copy the private key via SCP. You then load the private key and certificate into the 2nd server.

To get the private key. Login to the server that has the installed certificate via SCP as root.

The file is privkey.pem in /tandberg/persistent/certs/

Since I just love being contrarian, we are running the same cert on both Expressway-E. It is not GoDaddy though. But feel free to take a look at how this works. Our expe are vbhexpe.voip.uah.edu and libexpe.voip.uah.edu and I've also attached the cert to this email.
