Full Stack Journey 047: Using Kubernetes And Crossplane To Provision Cloud Infrastructure

Today's Full Stack Journey episode explores the Crossplane project, which uses APIs in Kubernetes and public cloud providers to allow you to provision and manage cloud services and infrastructure from Kubernetes. Crossplane maintainer Daniel Mangum is our guide.

Disowning a process in Linux

When you want a process to continue running even after you log off a Linux system, you have a couple options.One of them is to use the disown command. It tells your shell to refrain from sending a HUP (hangup) signal to the process when you log off. So, the process continues running. This can be very handy whenever you start a process and then, for some reason, you can’t stay logged in and wait until it finishes.[Get regularly scheduled insights by signing up for Network World newsletters.] The disown command is a shell built-in. This means that you don’t have to install it to use it, but it also means that it won’t be available if you use a shell that doesn’t support it. For those of us using bash and related shells (zsh, ksh etc.), disown should be available and you can verify this with a command like this that lists shell built-ins and then looks for "disown":To read this article in full, please click here

Cisco targets WAN edge with new router family

Cisco has launched a family of core and branch routers that take aim at refining secure, cloud resource access distributed at the edge.Cisco Catalyst 8000 edge router family includes three models--the high-end 8500 for data-center or colocation customers, the 8300 for branch users, and the software-based 8000 for virtual environments and feature support for advanced routing, SD-WAN,  security and secure-access service edge (SASE)--depending on customer requirements.To read this article in full, please click here

Bot Attack trends for Jan-Jul 2020

Bot Attack trends for Jan-Jul 2020
Bot Attack trends for Jan-Jul 2020

Now that we’re a long way through 2020, let’s take a look at automated traffic, which makes up almost 40% of total Internet traffic.

This blog post is a high-level overview of bot traffic on Cloudflare’s network. Cloudflare offers a comprehensive Bot Management tool for Enterprise customers, along with an effective free tool called Bot Fight Mode. Because of the tremendous amount of traffic that flows through our network each day, Cloudflare is in a unique position to analyze global bot trends.

In this post, we will cover the basics of bot traffic and distinguish between automated requests and other human requests (What Is A Bot?). Then, we’ll move on to a global overview of bot traffic around the world (A RoboBird’s Eye View, A Bot Day and Bots All Over The World), and dive into North American traffic (A Look into North American Traffic).  Lastly, we’ll finish with an overview of how the coronavirus pandemic affected global traffic, and we’ll take a deeper look at European traffic (Bots During COVID-19 In Europe).

On average, Cloudflare processes 18 million HTTP requests every second. This is a great opportunity to understand how bots shape the Continue reading

Going Postal

The Internet was not the first communications system constructed as compound service, where the end-to-end service was built using the services provided by many individual service providers. International telephony was constructed in a similar manner, and predating the telephone was the international postal service. In this article I’d like to look at the Universal Postal Union's track record of trying to construct a fair and efficient way to allow each service provider to be compensated for their part in the construction of the delivered end-to-end service. As with the Internet, it all comes down to the choice of the framework for settlement and peering between providers.

My Journey Towards the Cisco Certified DevNet Specialist – Service Provider by Nick Russo

On 14 October 2020, I took and passed the Automating Cisco Service Provider Solutions (SPAUTO) exam on my first attempt. This is the fifth DevNet exam I’ve passed and was a topic area in which I was already strong. Many people know me for my CCIE Service Provider Comprehensive Guide where I cover advanced SP technology. Others know me for my Pluralsight Ansible and Python network automation courses that implement an “infrastructure as code” solution to manage MPLS L3VPN route-targets. Suffice it to say that I’ve been doing SP stuff for a while.

Compared to the other concentration exams I’ve passed (ENAUTO and SAUTO), SPAUTO was about the same level of difficulty. The exam has a fair amount of carryover from DEVASC, DEVCOR, and ENAUTO, given the similarities of their blueprints, but is still quite heavy on SP products. Fortunately, there are only a few key products listed on the blueprint, making it narrower than SAUTO (which tested about 15 different APIs). Like ENAUTO, strong Python and network automation skills are important for this exam, and I’d strongly recommend having real-life SP design, implementation, and operations experience before attempting it.

Unlike DEVASC, DEVCOR, ENAUTO, and Continue reading

How to enforce password complexity on Linux

Deploying password-quality checking on your Debian-based Linux servers can help ensure that your users assign reasonably secure passwords to their accounts, but the settings themselves can be a bit misleading.For example, setting a minimum password length of 12 characters does not necessarily mean that all your users' passwords will actually have 12 or more characters.Let's stroll down Complexity Boulevard and see how the settings work and examine some that are worth considering.[Get regularly scheduled insights by signing up for Network World newsletters.] The files that contain the settings we're going to look at will be:To read this article in full, please click here
