that is *not* the same and frankly that breaks not only "ab", also older browsers - please look at the thread below, handshake compatibility != protocol
i have disabled sslv2 *asnd* sslv3 on any httpd without breaking older clients and combined with the fact that ATS don't support DHE ciphers "ssllabs" lists *a lot* of clients not able to talk with ATS over TLS
http://comments.gmane.org/gmane.comp.apache.devel/54510
can that be the reason "ab -c 100 -n 100000" fails to a ATS? keep in mind that don't mean sslv3 or even sslv2 are enabled!Not really sure about that, but should be easy to test when I get a minute.
see above
HTTPD: Heartbeat (extension) Yes TS: Heartbeat (extension) No how does ATS that using the same openssl binaries? "OPENSSL_NO_HEARTBEATS=1" as ENV don't disable it for httpdYou need to set OPENSSL_NO_HEARTBEATS=1 at OpenSSL build time
i know but.....
I don't know why we would not be vulnerable to heartbleed with a vulnerable OpenSSL version. I poked around in OpenSSL and mod_ssl for a while and AFAICT heart beats are enabled by default. I didn't see any special knob that would turn it on.
but https://www.ssllabs.com/ssltest/ says "Heartbeat (extension) No" on a Fedora 20 machine with ATS and the same OS and SSL binaries than httpd
