We’re celebrating International Women’s Day this year with great news: The Internet Society welcomes a new Chapter in Lesotho – and the Chapter’s president, vice president, treasurer, secretary, as well as a board member are all talented tech women.
Lesotho is a small landlocked country within South Africa, where less than a third of its population is connected to the Internet. One of the Lesotho Chapter’s key priorities this year is to start an “Internet for Education” project, which aims to encourage five schools to use the Internet to support teaching and to improve the quality of education.
Please join us in welcoming the Lesotho Chapter, then learn about its President Ithabeleng Moreke and other women around the world who are using the Internet to make a difference in their communities!
Ithabeleng Moreke enjoys the world of the Internet and all things networks, the technology behind it, and Internet security – and how they affect our everyday lives. She’s worked as network engineer for the government of Lesotho and is now with Vodacom Lesotho.

On today's sponsored Heavy Networking, VIAVI Solutions joins the Packet Pushers to discuss the intersection of network performance management (NPM) and security. We discuss how network and security teams can leverage VIAVI's packet capture capabilities, how it enriches flow records with additional data to provide valuable context, and how the concept of end user experience informs VIAVI's approach to NPM.

In my last post – we took a look at how we could leverage etcd from Python. In this post, I want to propose a use for leveraging etcd as a sort of message bus for ExaBGP. We saw some pretty compelling features with etcd that I think can work nicely in our ExaBGP model. So without further blabbering – let’s start coding.
Note: I assume you have a local instance of etcd installed and it is currently empty. If it’s not empty – you’ll want to clear it all out using a command like this ETCDCTL_API=3 etcdctl del "" --from-key=true
If you recall – in our last post on ExaBGP we were at a point where the ExaBGP process was using two Python programs we wrote. One for processing received routes (exa_bgp_receive.py
) and one for sending route updates (exa_bgp_send.py
). My goal here it to remove a lot of the logic for static route processing from these two scripts and make them more about route processing. More specifically – I want to turn the two Python scripts that ExaBGP is running on our behalf into simple programs that read/write to to/from etcd. Once we Continue reading
Wherever you look you find three kinds of people: those that build tools they need, those that find the tools they need, and those that yammer about the lack of tools without ever doing anything to solve the problem.
Daniel Teycheney is clearly in the first category. When faced with “collect some data and create a simple report” hands-on assignment during the Building Network Automation Solutions course he started creating a toolbox of playbooks that can be used in initial network auditing. I’m positive you’ll find tons of useful tidbits in his code ;)

As going through learning some basic programming, I encountered Decorators. I should be very honest if any of you are trying to figure out or learn what decorators in python do from my blog post you are dangerously in trouble.
So what this post about if not learning, well its mostly on what the functionality is so that you can learn the concept from better programming resources.
Let’s examine the below code
The output will be something like below
What’s in this code:
The first thing you have to realize is that some representation with ‘@’ symbol. If you have noticed get_reinfo and get_modelinfo functions, they have one thing in common which is to connect to the device and get output before they parse the required fields, that what a Decorator is helping us to do here, we extend that wrapping functionality around new functions without having to write everything or globalize everything.
At least that is what I understood. So, next time when you are writing some code try to think if you can incorporate decorators into them.
