Thanks.

Your ciphersuite is wrong anyway. You want DHE, not DH, for PFS.

Either I miss something subbtle, or I am right:

$ openssl ciphers DH:!SHA:!aNULL|tr ':' '\n' DHE-DSS-AES256-GCM-SHA384 DHE-RSA-AES256-GCM-SHA384 DHE-RSA-AES256-SHA256 DHE-DSS-AES256-SHA256 DHE-DSS-AES128-GCM-SHA256 DHE-RSA-AES128-GCM-SHA256 DHE-RSA-AES128-SHA256 DHE-DSS-AES128-SHA256

$ openssl ciphers DHE:!SHA:!aNULL|tr ':' '\n' Error in cipher list
