I'm planning to show how heartbleed bug work in my class by making small exercising web server. so using virtual machine, i installed Ubuntu 14.04 OS, which has vulnerable version of openssl(1.0.1f). and installed apache2, made small web site. But when i run heartbleed python code to that web site in my mac os, i only got
`Connecting...
Sending Client Hello...
Waiting for Server Hello...
... received message: type = 22, ver = 0302, length = 66

... received message: type = 22, ver = 0302, length = 4
Sending heartbeat request...
Unexpected EOF receiving record header - server closed connection

Should it be vulnerable to this attack? I don't know why this result come out
