The post Worth Reading: Breach Presumption appeared first on 'net work.
I mentioned a few months ago that I had been asked to write some thought-provoking blogs on the subject of network management for the Solarwinds Thwack Community “Geek Speak” area. I’ve now finished my six posts, and while they won’t be reproduced on movingpackets.net, I’m linking to them here as I think they touch on some subjects close to my Software Defined Heart.

I hope you find something to think about or react to there. I’ve tried to blend some hyperbole with a tablespoon of annoyance and a light dash of technical reality. If you have any specific comments on any of these posts, the right thing to do would be to login to Thwack and comment there, but I’ll take any feedback you want to give, wherever it is.

This last week I received an email from a friend asking about scaling. The situation is this: a particular company has well over 100 EIGRP routers on a single L2 service from a provider. Will this scale? What’s more interesting than simply asking about scale, though, is to ask the “why” question — no matter […]

If you’ve been a networking engineer (or a sysadmin) for a few years, you must be pretty familiar with DHCP and might think you know everything there is to know about this venerable protocol. So did I… until I read the article by Chris Marget in which he answers two interesting questions:
We've got a great show for you this week. Mark Dowd drops by to talk about the recent spate of Trojaned iOS apps that made it into Apple's China App Store. We also talk to him about his awesome AirDrop bug. How did it work?
This week's sponsor segment is actually a real cracker. Context IS consultant David Klein tells us how he owned an entire cloud platform by enumerating some shitty 90s-style bugs in some third party libraries they were using. It's comedy gold. This cloud platform that uses security at a selling point. It's bad.
I finally had the chance to finish watching all of the Arista videos from Networking Field Day 10. They did quite a few presentations and if you haven’t watched them yet I would recommend you do…
While the bulk of the videos talked about Arista platforms or features, Ken Duda’s presentation (EOS Evolution and Quality) really struck a chord with me. Early in the presentation Ken summarizes the problem by saying “when the network ain’t working, ain’t nothing working”. The software powering your network just has to work and it has to work consistently. Ken then goes into where he thinks quality should come from breaking it into 3 pieces.
Culture – It’s obvious from Ken’s talk that Arista legitimately cares about software quality. While I don’t think this is unique to Arista, I think it’s something they’ve fully embraced because they can. Arista was born out of the commodity network era. When you are working with commodity chips, the real differentiator becomes software. This puts them at a unique position compared to other traditional vendors who Continue reading
Having struggled in China since Snowden, Cisco is taking a new tack.
In this post, I’m going to show you how to use Docker Machine with OpenStack. This is something I’ve been interested in testing for a while, and now that I finally have my test lab back up and running, I was able to spend some time on this. I’ll spend some time later in the post covering my reasons for wanting to look at this, but I’ll start with the technical content of how it works.
I tested this setup with the following components:
There are (at least) two approaches to using Docker Machine and OpenStack together:
generic
driver to consume already-provisioned OpenStack instances. This is, in large part, very similar to what I covered here, but I’ll cover it in this post just for the sake of completeness.openstack
driver to automatically provision and configure new instances on an OpenStack cloud. This is the Continue reading
