Introducing NetQ — a fabric validation system providing unparalleled visibility

Today is a big day for us over here at Cumulus Networks! We are pleased to announce the launch of a brand new product designed to bring you unparalleled network visibility & remediation.  The newest addition to the Cumulus Networks portfolio, NetQ, is a telemetry-based fabric validation system that ensures the network is behaving as it was intended to. It allows you to test, validate and troubleshoot using advanced fabric-wide telemetry and Cumulus Linux.

Why NetQ?

To respond to the evolving industry, increasing business demands and growth, many companies have started the web-scale journey by deploying a fully programmable fabric with fully automated configurations across an open network infrastructure. Companies that have implemented some of these best practices are quickly seeing the benefits of agility, efficiency and lowered costs.

However, these organizations are also facing some unknowns: They are worried about making ad-hoc changes that disrupt the network and they can’t easily demonstrate “network correctness.” They’re interested in moving towards intent-based networking methods, but don’t have the right technology in place to do so.

Traditional operations tools and workflows weren’t built for the speed and scale that a modern cloud data center needs as they are manual, reactive and Continue reading

Don’t be left behind by IPv6 deployment, ISOC warns enterprises

They have the resources, the expertise and, though they may not realize it, the need -- but it turns out that enterprises are often the ones that don't yet have IPv6.That's the finding of the Internet Society its latest report on IPv6 deployment, published five years after the organization began a worldwide push to deploy the new addressing protocol and almost 20 years after the protocol was defined.Around 13 percent of the top one million websites is inviting IPv6 traffic today, it said, citing a Hurricane Electric analysis of data provided by Amazon.com. That figure rises to around 22 percent for the top 1,000 websites.In 37 countries, IPv6 is used for over 5 percent of internet traffic, according to Google, which bases its estimate on traffic hitting its load-balancers.To read this article in full or to leave a comment, please click here

Self-Study Exercises Added to Ansible for Networking Engineers Webinar

Last week I published self-study exercises for the YAML and Jinja2 modules in the Ansible for Networking Engineers webinars, and a long list of review questions for the Using Ansible and Ansible Deeper Dive sections.

I also reformatted the webinar materials page. Hope you’ll find the new format easier to read than the old one (it’s hard to squeeze over 70 videos and links on a single page ;).

Oh, and you do know you get Ansible webinar (and over 50 other webinars) with ipSpace.net subscription, right?

Certification – Major News for Expert Level Recertification

Certification – Major News for Expert Level Recertification

Everyone holding an expert level Cisco certification knows the pain of recertifying. Recertification today is achieved by taking any expert level written exam which means you can take the written in the track you are already certified in (the “safe bet”) or in another track if you want to learn something new. The quality of these written exams have varied over the years. Some revisions have been very difficult to pass even for people that are masters of their trade due to the pool of questions not being as high quality as can be expected from an expert level exam. This has been debated for years.

Every two years the pain of recertifying kicks in. Taking the written exam costs around 400$ per attempt depending on local rates, VAT etc. Many people have had to go through multiple attempts to recertify and some have chosen other written exams than their own track because the written of that track was not up to par quality-wise.

Over the years we have been many that have suggested that there must be a better path to getting recertified. Many of us go to Cisco Live, write Continue reading

Docker Enterprise Edition Now on G-Cloud 9 Framework

 G-Cloud 9

Docker Enterprise Edition (EE) has been accepted to G-Cloud 9, further exemplifying Docker’s commitment to delivering tools for application modernization and innovation across the UK public sector.

G-Cloud 9 is the UK government’s latest framework that is designed to simplify and accelerate adoption of cloud-based services within the public sector. The inclusion of Docker Enterprise Edition subscriptions, training and Professional Services Organization (PSO) within HM Government Crown Commercial Service’s (CCS) G-Cloud 9 Framework gives UK public sector organizations the opportunity to procure the de facto container solution through the online store known as the “Digital Marketplace” without needing to run a full tender, competition or lengthy procurement process.

Docker’s meteoric rise within enterprise-class business has been built on its ability to be agnostic, agile and secure – whether for hybrid cloud migration, modernizing the application stack or adopting a DevOps methodology.

Bringing application modernization to the public sector

With the UK government’s shift to cloud and DevOps, and move away from locked-down IT contracts in favor of smaller suppliers, Docker perfectly addresses these needs by giving  UK public sector organizations the ability to innovate, transform, define, select and control their infrastructure. Additionally, these organization can retain staff who now feel engaged as they can run their programs Continue reading

How The Intercept Outed Reality Winner

Today, The Intercept released documents on election tampering from an NSA leaker. Later, the arrest warrant request for an NSA contractor named "Reality Winner" was published, showing how they tracked her down because she had printed out the documents and sent them to The Intercept. The document posted by the Intercept isn't the original PDF file, but a PDF containing the pictures of the printed version that was then later scanned in.

The problem is that most new printers print nearly invisibly yellow dots that track down exactly when and where documents, any document, is printed. Because the NSA logs all printing jobs on its printers, it can use this to match up precisely who printed the document.

In this post, I show how.

You can download the document from the original article here. You can then open it in a PDF viewer, such as the normal "Preview" app on macOS. Zoom into some whitespace on the document, and take a screenshot of this. On macOS, hit [Command-Shift-3] to take a screenshot of a window. There are yellow dots in this image, but you can barely see them, especially if your screen is dirty.

We need to highlight the yellow Continue reading

BrandPost: Selecting the Right Managed SD-WAN Service Provider

Many of you are already aware that an SD-WAN enables distributed enterprises to connect users to applications with the flexibility to use any combination of underlying transport technologies (MPLS, broadband, LTE), bring branch offices online quickly and become more agile, all while saving money.THE VALUE OF CHOOSING AN SD-WAN MANAGED SERVICEHowever, finding the right SD-WAN solution for your business can take time and may not always be the highest business priority, given other digital transformation project priorities. The accelerating pace of technological change within the SD-WAN segment can also lead to confusion. It’s no surprise that many enterprises considering an SD-WAN to simplify their branch WAN deployments are turning to managed service providers to deploy and manage an SD-WAN as a managed service. As I wrote in my previous blog, there is tremendous value in working with a managed service provider for an SD-WAN.To read this article in full or to leave a comment, please click here

Defining Cybersecurity

Cybersecurity, as defined by Merriam-Webster, is “measures taken to protect a computer or computer system (as on the Internet) against unauthorized access or attack.”

—

The true importance of cybersecurity can only be understood if our dependence on “computer systems” is understood. It is difficult to imagine a day using nothing that is actively dependent on technology. We depend on connected systems to purchase groceries, perform medical procedures, manage the delivery of utilities and facilitate communications. These systems facilitate safe travel and alert us of impending dangers. It is conceivable that a cyberattack could take the power grid offline making it difficult or impossible to fill a car with fuel, purchase groceries, receive healthcare and even gain access to the typical procedures to restore the grid itself.

In our world today, unless we are primitive camping, we are using products of computer systems continually. To state it differently, our lives would change drastically if these systems became under widespread compromise. Considering Maslow’s hierarchy of needs, most individuals in a civilized society depend on computer systems for most of the elements defined in the critical first two layers. Since we have built this dependence, we must also protect these systems Continue reading

Top 5 skills needed for the industrial IoT
