Building a router with Open vSwitch
As part of my work in OpenDaylight, we are looking at creating a router using Open vSwitch... Why? Well OpenStack requires some limited L3 capabilities and we think that we can handle those in a distributed router.

Rolling back to Maven 3.0.X on OSX (Homebrew)
The current version of Maven in Homebrew at the time of writing is 3.2.2
This is great... unless one of the plugins in your project doesn't support it and then you have to downgrade :(
Fortunately it's not too painful
brew uninstall maven
brew tap homebrew/versions
brew install …Rolling back to Maven 3.0.X on OSX (Homebrew)

Creating a Vagrant base box for RHEL with Bento
I <3 the Opscode Bento project. I use the Amazon S3 hosted images for pretty much all of my Vagrant boxes. When I started to use RHEL, I didn't want to make an exception... Fortunately Bento allows you to build your own RHEL, OSX or Windows boxes using Packer. This is how I built my RHEL 6.4 x64 box, but this process should work for any other box you want to build manually...

OpFlex – is the abstraction in the right place?

SSH for Python – In search of API perfection
My mission is simple: Establish an SSH connection to a device and run some commands in as few lines as possible. The contenders? Paramiko, Spur and Fabric.

NETCONF, YANG, RESTCONF and NetOps in an SDN World
I've had some great discussion with the OpenDaylight OVSDB team around NETCONF, YANG, RESTCONF and what network operations will look like in an SDN world. This post summarizes where my head is at on this subject.

Installing KVM, Libvirt and Open vSwitch on Fedora
In my NetOps to DevOps Training Plan I mentioned installing KVM, Libvirt and Open vSwitch. I did this a few weeks ago and documented it to produce this tutorial. My motivation was to replace my VMware environment at home with something Open Source. I am also a strong believer in "eat your own dog food" and as a lot of the work I am doing in the Open Source community centers around these 3 technologies, I should get used to using them every day...

Network Flavors in OpenDaylight
OpenStack uses the concept of flavors to define compute/storage configurations that vary in terms of resource consumption. When we start to consume the network as a resource pool, we need a similar concept. This post explains how this is achieved in the context of the Flavors application in the OpenDaylight project

A NetOps to DevOps Training Plan
In one of my rants, I asked people to kindly stop with the "All Network Guys will Need to be Programmers" FUD. My recommendation was basically for Networkers to be open to change, and to start broadening their horizons. DevOps is coming to networking and that is a FACT. You might be wondering what skills a Network DevOps Engineer needs and here I attempt to answer that.
