Verifying TDD Scenarios
Now that Ansible has done all the information gathering for us it’s time to finally make use of it. In this post I will show how to use Ansible to run traceroutes from and to the hosts defined in a test scenario and perform verification of the results of those tests. Should any of those tests fail, Ansible will provide a meaningful description of what exactly failed and why. While doing all this I’ll introduce a couple of new Ansible features like conditional looping and interactive prompts.

Some Ridiculous SD-WAN Claims
SDx Central is usually a pretty good web site that I love to read, but even they occasionally manage to publish a gem like this one:
The problem with MPLS and similar technologies is that they weren’t designed with today’s business challenges in mind. Today, a company may need to launch an overseas R&D office overnight, or it may acquire a startup and want to immediately network with offices in distant regions and countries. Older technologies just don’t have the flexibility to do this on the fly.
Not surprisingly, the above paragraph triggered a severe case of Deja-Moo.

Risky Business #373 — Hacking Team gets owned. Quite a lot.
Obviously the Hacking Team breach is the big story of the week and we'll be jumping right into that.
It's a jam packed podcast this week -- we check in with Dave Aitel of Immunity to talk about the impending Wassenaar Arrangement disaster about to hit America. We're also joined by Claudio Guarnieri.
Claudio has spent years tracking Hacking Team's malware to the darkest regions of the planet. For a long time he's been claiming Hacking Team were up to no good, now we know he was right. We get him on to the show for a well-earned gloat.
Big Flowering Thing
This is a rant. It borrows emotional (and some verbal) inspiration from Lewis Black’s “Big F**king Thing” bit. However, in order to keep things light and professional, I will be using the term “flower” in lieu of the four-letter word that I am using in my head.
It’s not unreasonable that ongoing operations for existing applications, and as a result, remaining profitable, have been and always will be the priority. It’s easy to sit atop an ivory tower and critique all of the shortcomings of the industry (applies anywhere, not even just IT), but the reality is, IT (and specifically network infra) is kind of a mess. And that’s okay! It’s the nature of growing organically - and few disciplines have had to learn this the hard way like network infrastructure. Most importantly, we’re all running businesses here. Nothing takes priority over the need to provide ongoing products and services to customers, and to be honest, the rant contained in this post actually points out the need for changes in our industry to be more conducive to this imperative.
All of that said, I feel like the entire networking industry (as well as other, seemingly better-off disciplines to some degree) Continue reading
