B1 HANA - weak ephemeral Diffie-Hellman key in Server

[former_member260921]

Hi,

I have successfully installed Suse Linux, HANA 74 and B1 Server Tools 9.1. Everything seems to be running correctly but when I try to browse to the SLD Control Center I get the error message:

ssl_error_weak_server_ephemeral_dh_key

This happens for both Chrome and Firefox browsers so I think the problem is with the server. It doesn't matter whether I run the browser on the linux console or remotely from a workstation. In either case I get the error.

I have tried various approaches that I found on google, including trying to use Open SSL, and creating a new 2048 bit key and created a certificate.

I re-installed SLD to ensure that the certificate was implemented and I installed the certificate on the browser.

But I still get the same error.  I think I am missing something but don't know where to look.

Is there a clear set of steps that will resolve this issue?

Thanks for any help.

Regards,

Mel

Hi,

You have to change value true to false in browser cofig for this records:

- security.ssl3.dhe_rsa_aes_128_sha

- security.ssl3.dhe_rsa_aes_256_sha

Open new tab and in address bar, put about:config

and accept the risk.

Next plese find these records, change these values to false

and refresh browser. It solved my problem.

I hope it help.
