Video: IPv6 Myths and Reality
I was talking and writing about IPv6 myths for years, but like any good myth they tend to be pretty robust. Unfortunately, as I explained in the IPv6 Myths and Reality part of IPv6 High Availability Strategies webinar, the reality seems pretty bleak: all we got are longer addresses, half-baked protocols, unsolved challenges, and heaps of confusion.
How to use MiniEdit, Mininet’s graphical user interface
The Mininet network simulator includes MiniEdit, a simple GUI editor for Mininet. MiniEdit is an experimental tool created to demonstrate how Mininet can be extended.
To show how to use MiniEdit to create and run network simulations, we will work through a tutorial that demonstrates how to use MiniEdit to build a network, configure network elements, save the topology, and run the simulation.
Set up Mininet
You should already be familiar with Mininet before trying to use MiniEdit. If you need some basic information about Mininet, please read my Mininet overview.
Before starting this tutorial, you should have already started the Mininet VM and connected to it via SSH with X forwarding enabled. If you need to learn how to do this, please read my post describing how to set up Mininet. If you want to use Mininet on an Amazon EC2 server, please see my post about installing Mininet on Amazon EC2.
Start MiniEdit
The MiniEdit script is located in Mininet’s examples folder. To run MiniEdit, execute the command:
$ sudo ~/mininet/example/miniedit.py
Mininet needs to run with root privileges so we started MiniEdit using the sudo command.
MiniEdit user interface
MiniEdit has a simple user interface that Continue reading

Ansible and Containers: Why and How
Everyone loves the promise of containers.
More specifically: everyone loves the promise of a world where they can build an application on their laptop, and have that application run exactly the same way in every environment -- from their laptop all the way to production, and at every step in between.
That's still a holy grail, though. In the meantime, people seem to be looking for practical ways to get all of the advantages of containers -- consistency, lightweight environments, application segregation, and so on -- while still maintaining the flexibility required to work with the many environments that are not amenable to containerization.
Which may explain why so many people... wow, just a lot of people... seem to be talking about Ansible and containers together:
* Ansible playbooks are portable. If you build a container with a pure Dockerfile, it means that the only way you can reproduce that application is in a Docker container. If you build a container with an Ansible playbook, you can then reproduce a very similar environment in Vagrant, or in a cloud instance of your choice, Continue reading
