SSL Labs A+ Certification for Apache 2.4

After gaining some insight from Seth Vargo’s excellent post on doing the same things with nginx, I decided to tweak my Apache 2.4 config to get the same results: At first, I got everything but the TLS_FALLBACK_SCSV support. I did some digging and discovered that I had missed and OpenSSL update. Applying that and then restarting apache did the trick. Here are the relevant security announcements with the required versions of OpenSSL for ubuntu, debian, and RHEL/CentOS.

OpenStack != Free VMware

Last week was the OpenStack Juno Design Summit in Atlanta Georgia. I spent a lot of time in the Operations track, and there was a recurring theme: “OpenStack needs more enterprise features”. OKay, fair enough. But what features? “Integration into enterprise authentication?” Sure, we do that now with SAML2 in Keystone. “HA of OpenStack services” Also, available now. Two different methods even! You can run active/passive with corosync, or (my preferred way) run mutliple instances behind a highly-available load balancer.

Beginning of the end

Atlantis departed this rock for the final time today, and I was somewhat surprised that it did. On the one hand I knew this was a big deal for NASA that the final mission go off without a hitch, but with bad weather looming I was surprised the safety paranoia didn’t take over. While I am sad that the shuttle program is ending, I’m not as optimistic as Phil Plait that this isn’t the end.

Building an IPv6 Firewall

As As will gladly tell you, we are rapidly running out of unique IP addresses on the Internet. The good news is we solved this problem in 1998. The bad news is that, after more than ten years, we still haven’t widely implemented the new standard: IPv6. All of the big carriers support it, but getting access to the IPv6 Internet is still very tough. If you are a Comcast customer it is possible to get IPv6 access, and there are a few others who allow access as well.

Please stop developing for CentOS 5

Good gravy, this has been the bane of my existence of recent. I get it, it’s got “Enterprise” in the title and makes you compatible with RHEL. But, your kernel is SEVEN YEARS OLD. Hardware that was common place then is non-existent now and hardware that is common place now was poorly supported then (I’m looking at you, bnx2). We have better options out there now: Ubuntu Server and Ubuntu Server LTS release on regular cycles and have much more recent kernels.

Getting things done

Working between three offices, one of which don’t even have desks, has been interesting. Keeping track of things that need to be done has been downright awful. I hate brush fires at work, and recently I’ve been creating them just because I’ve not been in a constent place with my trusty todo pad around. So, I decided to add some tech to the problem. I have Astrid Tasks on my phone, and it’s nice but adding tasks is not.

Thoughts on TRON: Legacy

I’m going to out myself: I really liked this movie. Yep, I’m one of those: the few and the proud. However truth be told I didn’t like it at first. I walked in to TRON: Legacy expecting an action film, and the first twenty minutes did not disappoint. Light cycles, light car, disc wars, recognizers, it was all there. Then it just stopped, and that’s when I became confused. It was still a visual masterpiece, but something wasn’t right.
