What's to say? Check my personal website for a touch more detail, if you want to. I've been a professional UNIX/network sysadmin since 1991, and currently sysadmin free software professionally through my own little company. A long time ago, I and a co-author wrote "Building Linux and OpenBSD Firewalls" (Wiley, 2000). That's it.

And it's worked - you just don't realise that it's worked. My answer here may help shed some light on why you've been rendered safe and up-to-date even though your SSL version number hasn't changed.

Either the server has to have the key locally, or not. If the former, the key can be recovered from the unencrypted FS; if the latter, then the service can't be restarted without remote assistance - which session can be intercepted.

+1 for this question from me, for not redacting the domain name. Made solving the problem easy, instead of a punishing series of how-about questions. Thanks, Robert.

In short, no. You can make it more difficult, but in the end, if you've got hold of a system, you control it.

comment Samba / smbd on Centos 6.5
I think Iain was on the right track here. Try a service iptables stop and see if that gets you more log information, or even full functionality. Either of those means you have a firewall issue, which we can address after you've diagnosed it.
