Re: OpenSSL version used by Httpd

[Oscar Knorn <oscar.knorn@xxxxxxxxxxxxxxxxxxxxx>]

Is there a way to specify/modify the order of locations in the path of where to look for the libraries in compile/run time?
Might help.

Hey 

Thank you very much for quick reply, I did modify ServerTokens from OS to Full and did restart apache. However I tried to hit my server I do not see server header added. Is there any other precondition that I need to take care of I am using Apache HTTPD 2.2.25.

In your httpd.conf specify

        ServerTokens Full

Then from the client side you can inspect the headers for the OpenSSL
version. eg: http://httpd.apache.org/ currently reports:

        Server: Apache/2.4.11 (Unix) OpenSSL/1.0.1l

See http://httpd.apache.org/docs/2.2/mod/core.html#servertokens
You might consider this as information leakage so may not wish to leave
it permanently enabled.
