Data Mobility and Freedom Maximizes Its Business Value
Companies that fail to manage their unstructured file and object data often end up with unstructured data silos, leaving valuable intelligence on the table.IETF 109
The latest IETF meeting was held in mid-November. Here I’m going to pick just one presentation from each of a small collection of the week’s working group meetings and explore that topic in a little more detail.The History of EARN, RARE, and European Networks (part 1)
European networks from the mid-1980’s to the late 2000’s underwent a lot of change, bolstered by the rise and fall of America Online, the laying of a lot of subsea cables, and the creation of several organizations, including EARN and RARE, to bolster the spread and use of the Internet. Daniele Bovio joins Donald Sharp and Russ White on this episode of the History of Networking to give us a good overall perspective of this history.

New LibSSH Connection Plugin for Ansible Network Replaces Paramiko, Adds FIPS Mode Enablement
As Red Hat Ansible Automation Platform expands its footprint with a growing customer base, security continues to be an important aspect of organizations’ overall strategy. Red Hat regularly reviews and enhances the foundational codebase to follow better security practices. As part of this effort, we are introducing FIPS 140-2 readiness enablement by means of a newly developed Ansible SSH connection plugin that uses the libssh library.
Ansible Network SSH Connection Basics
Since most network appliances don't support or have limited capability for the local execution of a third party software, the Ansible network modules are not copied to the remote host unlike linux hosts; instead, they run on the control node itself. Hence, Ansible network can’t use the typical Ansible SSH connection plugin that is used with linux host. Furthermore, due to this behavior, performance of the underlying SSH subsystem is critical. Not only is the new LibSSH connection plugin enabling FIPS readiness, but it was also designed to be more performant than the existing Paramiko SSH subsystem.
The top level network_cli connection plugin, provided by the ansible.netcommon Collection (specifically ansible.netcommon.network_cli), provides an SSH based connection to the network appliance. It in turn calls the Continue reading
Leading from the Front: How the Internet Society’s Training Efforts Are Helping to Upskill Africa’s Future Digital Champions
Tech skills are important for digital transformation in Africa. To realize this transformation, the Internet Society is supporting work-ready digital skills development with local talent.
By 2030, over 230 million jobs in Sub-Saharan Africa will require digital skills. With the fourth industrial revolution taking shape, we are helping to build a community of digital champions in Africa who will fill the skills gap on the continent.
African governments are already banking big on the contributions that digital technologies will provide to this transformation. For example, the African Union’s Digital Transformation Strategy (2020-2030) wants to create a “Digital Single Market” for the continent, while national governments are increasingly embracing digitalization in several sectors of their economies.
But the continent needs the right talent for its ambitious economic agenda to succeed. Though more learners are taking interest in STEM (science, technology, engineering, and mathematics) subjects, school curricula in Africa primarily focus on theoretical learning with scarce engagement with digital subjects. This is one of the main reasons a skills gap exists for jobs that require digital skills.
To play a role in positively changing these circumstances, the Internet Society developed the Introduction to Network Operations course, which equips novice and intermediate level Continue reading
Fast Failover: Hardware and Software Implementations
In previous blog posts in this series we discussed whether it makes sense to invest into fast failover network designs, the topologies you can use in such designs, and the fault detection techniques. I also hinted at different fast failover implementations; this blog post focuses on some of them.
Hardware-based failover changes the hardware forwarding tables after a hardware-detectable link failure, most likely loss-of-light or transceiver-reported link fault. Forwarding hardware cannot do extensive calculations; the alternate paths are thus usually pre-programmed (more details below).

Pyenv Install Centos 8
cuction Pyenv is a similar tool to rbenv, where you can easily install and use mulitple versions of python. This allows you to test across multiple versions of python as well as pin an app to a specific release. Software Versions Used Centos - 8.2.2004 Pyenv - 1.2.21 Pre-requisites ...Advanced Threat Intelligence Begins with Network Visibility
The current reality has pushed users, applications, and data to the edge of the network —where traditional perimeter security solutions have historically fallen short. Threat actors know this, of course, and have spent the past nine months targeting the weakest link in the security stack: the user.
Email and web browsing continue to be popular attack vectors. Security vendors have beefed up web and email security, but issues with legacy architectures are letting some attacks slip through. Information and context derived from advanced threat intelligence remain the most powerful weapons in a security team’s arsenal. Advanced technologies such as artificial intelligence and machine learning can help scan, detect, and warn at scale, but they’re not bulletproof. Increasingly sophisticated threat actors, powered by AI and ML, are finding ways to evade threat detection.
Security professionals interested in learning more about the current state of advanced threat inspection, threat intelligence, and the emerging technologies that power these capabilities should check out the following sessions:

How do you become a “senior engineer?” It’s a question I’m asked quite often, actually, and one that deserves a better answer than the one I usually give. Charity recently answered the question in a round-a-bout way in a post discussing the “trap of the premature senior.” She’s responding to an email from someone who is considering leaving a job where they have worked themselves into a senior role. Her advice?
Quit!
This might seem to be counter-intuitive, but it’s true. I really wanted to emphasize this one line—
Exactly! Knowing the CLI for one vendor’s gear, or even two vendor’s gear, is not nearly the same as understanding how BGP actually works. Quoting the layers in the OSI model is just not the same thing as being able to directly apply the RINA model to a real problem happening right now. You’re not going to gain the understanding of “the whole ball of wax” by staying in one place, or doing one thing, for the rest of Continue reading

Great heights: As his classes move online, Russian student Alexei Dudoladov has to climb a birch tree to get Internet access, Reuters reports. The student at the Omsk Institute of Water Transport, which is nearly 1,400 miles east of Moscow, says his home Internet service is not strong enough to connect to online classes. “I need to go into the forest 300 meters from the village and climb a birch tree that is eight-meters high … and I get on Zoom to speak to professors and prove that I am not skipping class for no reason.”
Even greater heights: Meanwhile, the Ector County Independent School District in Odessa, Texas, is hoping that the new SpaceX satellite Internet service will help give students and teachers better Internet access, Education Dive says. The district is the first in the U.S. to work with SpaceX’s Starlink Internet service. A pilot project in early 2021 will include 45 families with students or teachers in the district.
