Big Switch Meets Ansible
Big Switch offers on demand labs to get instant access to Big Cloud Fabric (BCF) and Big Monitoring Fabric (BMF). Using these labs, it’s quite easy to experience the products first hand and see what they are all about. The labs also come with lab guides that walk you through step-by-step on how to get started using BMF and BCF.
For me, one of the more appealing aspects of these labs is that Big Switch also exposes the APIs such that you can access them directly from your personal machine. This makes it possible to not only test the product, but also test the API on each controller platform (BMF and BCF).
The best part is, you don’t even need to use any docs because they offer a command that shows the API calls being made by certain show commands.

Like the output from a show version? Ensure debug rest is enabled, and then just issue the command to grab the APIs being called to generate the text output on the CLI.

This is another post in the series of how to protect SSH keys with hardware, making them impossible to steal.
This means that you know that your piece of hardware (e.g. Yubikey or TPM inside your laptop) was actively involved in the transaction, and not, say, turned off and disconnected from the Internet at the time (like in a safe or on an airplane).
What’s new this time is that we can now have a physical presence test on every use of the key. That means that even if someone hacks your workstation completely and installs a keylogger to get your PIN, unless they also break into your home they can’t use the key even while the machine is on and connected. Evil hackers in another country are out of luck.
Intro
Most of this is a repeat of official docs (see references).
If it looks like a command is hanging, check to see if the Yubikey is flashing. If it is, then touch it.
The touch feature is optional. If you don’t want a key to require it, you can chose to generate a key that doesn’t.

In this post, I’m going to show you how to use macvlan interfaces with Docker for networking. The use of macvlan interfaces presents an interesting networking configuration for Docker containers that may (depending on your use case) address issues with the standard Linux bridge configuration.
Macvlan interfaces, if you’re unfamiliar with them, are a (somewhat) recent addition to the Linux kernel that enables users to add multiple MAC address-based logical interfaces to a single physical interface. These logical interfaces must reside in the same broadcast domain as the associated physical interface, which means that Docker containers attached to macvlan interfaces also will be in the same broadcast domain as the associated physical interface. In other words, the Docker containers will be on the same network as the host—no IPTables rules, no Linux bridge, just attached directly to the host’s network. This introduces some interesting possibilities (and potential challenges), but I’ll save that discussion for a future post.
Right now, macvlan supported is implemented via an unsupported Docker Network plugin hosted on GitHub. However, I suspect that the macvlan functionality found in this plugin will find its way into the core of Docker Network, and probably sooner rather than later.
