Which Apache version do you use?

Betreff: Odd - SSLCipherSuite

Now I must be getting rusty - we have in the config file

          SSLCipherSuite -ALL:ECDHE-RSA-AES256-SHA
          SSLProtocol -ALL +TLSv1.1 +TLSv1.2 +SSLv3

with the first resolving nicely with

          openssl ciphers -ALL:ECDHE-RSA-AES256-SHA

to just


So my assumption is that this server will insist on talking above - and =
nothing else.

And on the wire - if I observer the Server Hello I see:

          Secure Sockets Layer
                      TLSv1.2 Record Layer: Handshake Protocol: Server Hello
                      Cipher Suite: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 =

which is sort of what i expect.

However when I throw

their analyzer at it - it seems to be quite able to convince the server =
to say hello=92s with

              SSLv3 Record Layer: Handshake Protocol: Server Hello
          Content Type: Handshake (22)
                  Version: SSL 3.0 (0x0300)
                      Cipher Suite: TLS_RSA_WITH_RC4_128_MD5 (0x0004)


   TLSv1.2 Record Layer: Handshake Protocol: Server Hello
           Cipher Suite: TLS_DHE_RSA_WITH_DES_CBC_SHA (0x0015)

And so on*. I must be missing something very obvious here! Am I  misunderstanding SSLCipherSuite
or is there something specific about 1.2 which makes certain things mandatory and not under
control of SSLCipherSuite?


* besides             Cipher Suite: =
Server Hello=92s with
